President's Letter

Dear Shareowner,

The U.S. economy went through a soft patch in the first half of 2011, and the
second half of the year, so far, has been highlighted by the U.S. government's
battle over the debt ceiling and Standard & Poor's downgrade of the U.S.
Treasury's credit rating from the top rating of "AAA" for the first time in
history. The markets reacted quite negatively to the credit downgrade, and
there is concern about the strength of the global economy going forward.

Pioneer is cautiously optimistic that the U.S. economy will see moderate
economic growth over the balance of 2011, though at a slower pace than we had
expected earlier this year. While housing and employment remain weak, the
private sector shows signs of slow but steady improvement, led by higher
capital investment, solid exports, and improved consumption. At the same time,
the risks to growth remain substantial, including high unemployment, continued
delays in the housing sector's recovery, and the fiscal drag of U.S. federal
and state budget cuts.

The difficult recovery process has been accompanied by wide market swings.
While this is a challenging environment, our investment professionals continue
to focus on finding good opportunities to invest in both equity and bond
markets using the same disciplined approach Pioneer has used since 1928. Our
approach is to identify undervalued individual securities with the greatest
potential for success, carefully weighing risk against reward. Our teams of
investment professionals continually monitor and analyze the relative
valuations of different sectors and securities globally to help build
portfolios that we believe can help you achieve your investment goals.

At Pioneer, we have long advocated the benefits of staying diversified and
investing for the long term. The strategy has generally performed well for many
investors. Our advice, as always, is to work closely with a trusted financial
advisor to discuss your goals and work together to develop an investment
strategy that meets your individual needs. There is no single best strategy
that works for every investor.

investing by consulting with your financial advisor or visiting us online at

you for investing with Pioneer.

Portfolio Management Discussion | 8/31/11

In the following interview, Paul Cloonan, head of equity research, U.S., and
Ashesh ("Ace") Savla, vice president and senior quantitative research analyst,
discuss the market environment and other factors that affected Pioneer
Disciplined Growth Fund's performance over the 12 months ended August 31, 2011.
Mr. Cloonan and Mr. Savla are responsible for the day-to-day management of the
Fund.

Q  How would you characterize the investment environment for equities, over the
   12-month period ended August 31, 2011?

A  The U.S. equity market continued to advance through April 2011, driven by
   strong corporate earnings and attractive equity valuations compared to many
   other asset classes. With short-term interest rates at historically low
   levels and abundant liquidity due to the Federal Reserve Board's (the
   Fed's) "quantitative easing" program, investors became less risk-averse and
   increased their exposure to equities. In the last few months of the period,
   however, the equity market traded below the level it reached in late April
   2011, due to increasing macroeconomic risk factors such as slowing economic
   growth, the U.S. debt ceiling and fiscal debates, the debt crisis in
   Europe, and tighter monetary policy in China as well as other countries.
   Corporate earnings have continued to be strong, but there is risk that
   earnings growth could slow as a result of the macro factors. Despite the
   macro-related concerns at the end of the period, the Russell 1000 Growth
   Index, the Fund's benchmark, delivered a total return of 23.96% for the 12
   months ended August 31, 2011. The Russell 1000 Growth Index outperformed
   the Russell 1000 Value Index return of 14.37% over the same 12-month
   period, primarily due to the larger weighting of the financials sector in
   the Russell 1000 Value Index. The financials sector has been lagging other
   sectors due to regulatory risks, concerns about credit risk, sluggish loan
   growth and other factors.

Q  How did the Fund perform over the 12 months ended August 31, 2011?

A  Pioneer Disciplined Growth Fund Class A shares returned 21.62% at net asset
   value over the 12 months ended August 31, 2011, while the Fund's benchmark,
   the Russell 1000 Growth Index, returned 23.96%. Over the same 12-month
   period, the average return of the 763 mutual funds in Lipper's Large-Cap
   Growth Funds category was 21.33%.


4     Pioneer Disciplined Growth Fund | Annual Report | 8/31/11


Q  The Fund underperformed the Russell 1000 Growth Index over the full 12-month
   period ended August 31, 2011. Could you highlight some of the factors
   behind the Fund's underperformance relative to the benchmark?

A  As designed, the Fund's performance is derived primarily from individual
   stock selection. The underperformance of the Fund during the 12-month
   period did not come from any clear macroeconomic factor or industry bias,
   but rather from specific individual securities that did not perform as well
   as the Russell 1000 Growth Index benchmark.

Q  What sector allocations or portfolio holdings disappointed during the
   12-month period ended August 31, 2011?

A  The Fund's underperformance during the period derived primarily from stock
   selection in two industry groups, retailing and capital goods. In
   retailing, Fund holdings Target and Staples both underperformed the overall
   group as both companies experienced weaker-than-expected sales. In capital
   goods, Fund holdings Textron and Ingersoll-Rand underperformed as slowing
   economic growth dampened the growth prospects for Textron's business jets
   (Cessna) and Ingersoll-Rand's air conditioning systems business.

Q  Given the fairly negative economic news over the past few months, what is
   your outlook for the remainder of 2011?

A  We remain optimistic about the outlook for equities, although some of the
   macro issues addressed in the first question above may provide headwinds
   for the equity market in the near term. Our optimism on the longer-term
   outlook for equities is supported by attractive equity valuations relative
   to other asset classes and our assumption that the economy will continue to
   grow. In addition, corporate balance sheets and cash flow are strong, which
   may lead to increased merger-and-acquisition activity, share repurchases
   and dividend increases.

   We will continue to focus our efforts on stock picking, which we believe is
   the Fund's key competitive advantage and primary performance driver. Our
   approach to stock picking emphasizes bottom-up, fundamental analysis. We
   believe our approach is durable and repeatable and can deliver reasonable
   investment results across the business cycle, and in a variety of market
   conditions.

of Fund securities.

Small- and mid-sized companies may offer the potential for higher returns, but
are also subject to greater short-term price fluctuations than larger, more
established companies. The Fund invests in a limited number of securities and,
as a result, the Fund's performance may be more volatile than the performance
of other funds holding more securities. At times, the Fund's investments may
represent industries or industry sectors that are interrelated or have common
risks, making it more susceptible to any economic, political, or regulatory
developments or other risks affecting those industries and sectors.

These risks may increase share price volatility.

Any information in this shareholder report regarding market or economic trends
or the factors influencing the Fund's historical or future performance are
statements of opinion as of the date of this report. These opinions should not
be relied upon for any other purposes. Past performance is no guarantee of
future results, and there is no guarantee that market forecasts discussed will
be realized.

month-end performance results. Current performance may be lower or higher than
the performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

NAV results represent the percent change in net asset value per share. Returns
would have been lower had sales charges been reflected. POP returns reflect
deduction of maximum 5.75% sales charge. All results are historical and assume
the reinvestment of dividends and capital gains. Other share classes are
available for which performance and expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers
may not be in effect for all funds. Certain fee waivers are contractual through
a specified period. Otherwise, fee waivers can be rescinded at any time. See
the prospectus and financial statements for more information.

The net expense ratio reflects the contractual expense limitation currently in
effect through January 1, 2012, for Class A shares. There can be no assurance
that Pioneer will extend the expense limitation beyond such time. Please see
the prospectus and financial statements for more information.

The performance table and graph do not reflect the deduction of fees and taxes

Call 1-800-225-6292 or visit us.pioneerinvestments.com for the most recent
month-end performance results. Current performance may be lower or higher than
the performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

Class C shares held for less than one year are also subject to a 1% contingent
deferred sales charge (CDSC). "If Held" results represent the percent change in
net asset value per share. Returns would have been lower had sales charges been
reflected. All results are historical and assume the reinvestment of dividends
and capital gains. Other share classes are available for which performance and
expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers
may not be in effect for all funds. Certain fee waivers are contractual through
a specified period. Otherwise, fee waivers can be rescinded at any time. See
the prospectus and financial statements for more information.

The net expense ratio reflects the contractual expense limitation currently in
effect through January 1, 2012, for Class C shares. There can be no assurance
that Pioneer will extend the expense limitation beyond such time. Please see
the prospectus and financial statements for more information.

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Fund distributions or the redemption of Fund
shares.

month-end performance results. Current performance may be lower or higher than
the performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

The performance shown for Class Y shares for the period prior to the inception
of Class Y shares on July 31, 2008, is based on the net asset value performance
of the Fund's Class A shares, which has not been restated to reflect any
differences in expenses, including Rule 12b-1 fees applicable to Class A
shares. Since fees for Class A shares generally are higher than those of Class
Y shares, the performance of Class Y shares prior to their inception would have
been higher than the performance shown.

Class Y shares are not subject to sales charges and are available for limited
groups of eligible investors, including institutional investors. All results
are historical and assume the reinvestment of dividends and capital gains.
Other share classes are available for which performance and expenses will
differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers
may not be in effect for all funds. Certain fee waivers are contractual through
a specified period. Otherwise, fee waivers can be rescinded at any time. See
the prospectus and financial statements for more information.

The net expense ratio reflects the contractual expense limitation currently in
effect through January 1, 2012, for Class Y shares. There can be no assurance
that Pioneer will extend the expense limitation beyond such time. Please see
the prospectus and financial statements for more information.

The performance table and graph do not reflect the deduction of fees and taxes

shares.


                Pioneer Disciplined Growth Fund | Annual Report | 8/31/11     11


Comparing Ongoing Fund Expenses

As a shareowner in the Fund, you incur two types of costs:

(1)   ongoing costs, including management fees, distribution and/or service
      (12b-1) fees, and other Fund expenses; and

(2)   transaction costs, including sales charges (loads) on purchase payments.

This example is intended to help you understand your ongoing expenses (in
dollars) of investing in the Fund and to compare these costs with the ongoing
costs of investing in other mutual funds. The example is based on an investment
of $1,000 at the beginning of the Fund's latest six-month period and held
throughout the six months.


Using the Tables
--------------------------------------------------------------------------------
Actual Expenses

The first table below provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period as
follows:

(1)   Divide your account value by $1,000
      Example: an $8,600 account value [divided by] $1,000 = 8.6

(2)   Multiply the result in (1) above by the corresponding share class's number
      in the third row under the heading entitled "Expenses Paid During Period"
      to estimate the expenses you paid on your account during this period.

-----------------------------------------------------------------------------


* Expenses are equal to the Fund's annualized expense ratio of 1.25%, 2.15%,
  and 0.90% for Class A, Class C, and Class Y shares, respectively, multiplied
  by the average account value over the period, multiplied by 184/365 (to
  reflect the one-half year period).

Hypothetical Example for Comparison Purposes

The table below provides information about hypothetical account values and
hypothetical expenses based on the Fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not the Fund's actual
return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.

You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
funds.

Please note that the expenses shown in the tables are meant to highlight your
ongoing costs only and do not reflect any transaction costs, such as sales
charges (loads) that are charged at the time of the transaction. Therefore, the
table below is useful in comparing ongoing costs only and will not help you
determine the relative total costs of owning different funds. In addition, if
these transaction costs were included, your costs would have been higher.

             assumptions in determining fair value of investments)


Generally, equity securities are categorized as Level 1, fixed income

Notes to Financial Statements | 8/31/11

1.    Organization and Significant Accounting Policies

Pioneer Disciplined Growth Fund, formerly Pioneer Research Growth Fund (the
Fund), is one of four portfolios comprising Pioneer Series Trust V, a Delaware
statutory trust. The Fund is registered under the Investment Company Act of 1940
as a diversified, open-end management investment company. The Fund was organized
on October 12, 2005, and commenced operations on December 15, 2005. The Fund's
investment objective is to seek long-term capital growth.

The Fund offers three classes of shares designated as Class A, Class C and Class
Y shares. Class C shares were first publicly offered on July 17, 2008. Class Y
shares were first publicly offered on July 31, 2008. Each class of shares
represents an interest in the same portfolio of investments of the Fund and has
identical rights (based on relative net asset values) to assets and liquidation
proceeds. Share classes can bear different rates of class-specific fees and
expenses such as transfer agent and distribution fees. Differences in
class-specific fees and expenses will result in differences in net investment
income and, therefore, the payment of different dividends from net investment
income earned by each class. The Amended and Restated Declaration of Trust of
the Fund gives the Board the flexibility to specify either per-share voting or
dollar-weighted voting when submitting matters for shareholder approval. Under
per-share voting, each share of a class of the Fund is entitled to one vote.
Under dollar-weighted voting, a shareholder's voting power is determined not by
the number of shares owned, but by the dollar value of the shares on the record
date. Each share class has exclusive voting rights with respect to matters
affecting only that class, including with respect to the distribution plan for
that class. There is no distribution plan for Class Y shares.

At times, the Fund's investments may represent industries or industry sectors
that are interrelated or have common risks, making the Fund more susceptible to
any economic, political, or regulatory developments or other risks affecting
those industries and sectors. The Fund's prospectus contains unaudited
information regarding the Fund's principal risks. Please refer to that document
when considering the Fund's principal risks.

The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the Fund
to, among other things, make estimates and assumptions that affect the reported
amounts of assets and liabilities, the disclosure of contingent assets and
liabilities at the date of the financial statements, and the reported amounts

                Pioneer Disciplined Growth Fund | Annual Report | 8/31/11     27


of income, expenses and gain or loss on investments during the reporting period.
Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements, which are consistent with
those policies generally accepted in the investment company industry:

A.    Security Valuation

      Security transactions are recorded as of trade date. The net asset value
      of the Fund is computed once daily, on each day the New York Stock
      Exchange (NYSE) is open, as of the close of regular trading on the NYSE.
      In computing the net asset value, securities that have traded on an
      exchange are valued at the last sale price on the principal exchange where
      they are traded. Securities that have not traded on the date of valuation,
      or securities for which sale prices are not available, generally are
      valued at the mean between the last bid and asked prices. Securities for
      which market prices and/or quotations are not readily available or are
      considered to be unreliable are valued using fair value methods pursuant
      to procedures adopted by the Board of Trustees.

      Trading in foreign securities is substantially completed each day at
      various times prior to the close of the NYSE. The values of such
      securities used in computing the net asset value of the Fund's shares are
      determined as of such times.

      The Fund may use fair value methods if it is determined that a significant
      event has occurred after the close of the exchange or market on which the
      security trades and prior to the determination of the Fund's net asset
      value. Thus, the valuation of the Fund's securities may differ from
      exchange prices.

      At August 31, 2011, there were no securities that were valued using fair
      value methods (other than securities that were valued using prices
      supplied by independent pricing services). Inputs used when applying fair
      value methods to value a security may include credit ratings, the
      financial condition of the company, current market conditions and
      comparable securities. Short-term fixed income securities with remaining
      maturities of sixty days or less generally are valued at amortized cost.
      Money market mutual funds are valued at net asset value.

      Dividend income is recorded on the ex-dividend date except that certain
      dividends from foreign securities where the ex-dividend date may have
      passed are recorded as soon as the Fund becomes aware of the ex-dividend
      data in the exercise of reasonable diligence. Interest income is recorded
      on the accrual basis. Dividend and interest income are reported net of
      unrecoverable foreign taxes withheld at the applicable country rates.

      Gains and losses on sales of investments are calculated on the identified
      cost method for both financial reporting and federal income tax purposes.

28     Pioneer Disciplined Growth Fund | Annual Report | 8/31/11


B.    Federal Income Taxes

      It is the Fund's policy to comply with the requirements of the Internal
      Revenue Code applicable to regulated investment companies and to
      distribute all of its taxable income and net realized capital gains, if
      any, to its shareowners. Therefore, no federal income tax provision is
      required. Tax years for the prior three fiscal years are subject to
      examination by tax authorities.

      The amounts and characterizations of distributions to shareowners for
      financial reporting purposes are determined in accordance with federal
      income tax rules. Therefore, the sources of the Fund's distributions may
      be shown in the accompanying financial statements as from or in excess of
      net investment income or as from net realized gain on investment
      transactions, or as from paid-in capital, depending on the type of
      book/tax differences that may exist.

      At August 31, 2011, the Fund reclassified $37 to decrease undistributed
      net investment income and $37 to increase accumulated net realized gain,
      to reflect permanent book/tax differences. The reclassification has no
      impact on the net assets of the Fund and presents the Fund's capital
      accounts on a tax basis.

      Under the recently enacted Regulated Investment Company Modernization Act
      of 2010, the Fund will be permitted to carry forward capital losses
      incurred in taxable years beginning after December 22, 2010 for an
      unlimited period. However, any losses incurred during those future years
      will be required to be utilized prior to the losses incurred in
      pre-enactment tax years. As a result of this ordering rule, pre-enactment
      capital loss carryforwards may be more likely to expire unused.
      Additionally, post-enactment capital losses that are carried forward will
      retain their character as either short-term or long-term capital losses
      rather than being considered all short-term as under previous law.

      The tax character of distributions paid during the years ended August 31,
      2011 and August 31, 2010 was as follows:



--------------------------------------------------------------------------------
                                                                2011        2010
--------------------------------------------------------------------------------
                                                                  
Distributions paid from:
Ordinary income                                           $2,691,667    $884,001
Long-term capital gain                                     1,063,387       8,768
--------------------------------------------------------------------------------
   Total                                                  $3,755,054    $892,769
================================================================================

      The following shows the components of distributable earnings on a federal
      income tax-basis at August 31, 2011:



--------------------------------------------------------------------------------
                                                                            2011
--------------------------------------------------------------------------------
                                                                   
Distributable earnings:
Undistributed ordinary income                                         $1,412,783
Undistributed long-term gain                                           2,898,028
Net unrealized gain                                                    2,485,455
--------------------------------------------------------------------------------
   Total                                                              $6,796,266
================================================================================


      The difference between book-basis and tax-basis unrealized appreciation is
      attributable to the tax deferral of losses on wash sales.

C.    Funzd Shares

      The Fund records sales and repurchases of its shares as of trade date.
      Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the
      Fund and a wholly owned indirect subsidiary of UniCredit S.p.A.
      (UniCredit), earned $4,357 in underwriting commissions on the sale of
      Class A shares during the year ended August 31, 2011.

D.    Class Allocations

      Income, common expenses and realized and unrealized gains and losses are
      calculated at the Fund level and allocated daily to each class of shares
      based on its respective percentage of adjusted net assets at the beginning
      of the day.

      Distribution fees are calculated based on the average daily net asset
      value attributable to Class A and Class C shares of the Fund, respectively
      (see Note 4). Class Y shares do not pay distribution fees. All expenses
      and fees paid to the transfer agent, Pioneer Investment Management
      Shareholder Services, Inc. (PIMSS), for its services are allocated among
      the classes of shares based on the number of accounts in each class and
      the ratable allocation of related out-of-pocket expenses (see Note 3).

      Distributions to shareowners are recorded as of the ex-dividend date.
      Distributions paid by the Fund with respect to each class of shares are
      calculated in the same manner and at the same time, except that net
      investment income dividends to Class A, Class C, and Class Y shares can
      reflect different transfer agent and distribution expense rates.

E.    Securities Lending

      The Fund lends securities in its portfolio to certain broker-dealers or
      other institutional investors. When entering into a securities loan
      transaction, the Fund typically receives cash collateral from the borrower
      equal to at least the value of the securities loaned, which is invested in
      temporary investments.

30     Pioneer Disciplined Growth Fund | Annual Report | 8/31/11


      Credit Suisse AG, New York Branch, as the Fund's securities lending agent,
      manages the Fund's securities lending collateral. The income earned on the
      investment of collateral is shared with the borrower and the lending agent
      in payment of any rebate due to the borrower with respect to the
      securities loan, and in compensation for the lending agent's services to
      the Fund. The Fund also continues to receive payments in lieu of dividends
      or interest on the securities loaned. Gain or loss on the value of the
      loaned securities that may occur during the term of the loan will be for
      the account of the Fund. The amount of the collateral is required to be
      adjusted daily to reflect any price fluctuation in the value of the loaned
      securities. If the required market value of the collateral is less than
      the value of the loaned securities, the borrower is required to deliver
      additional collateral for the account of the Fund prior to the close of
      business on that day. The Fund has the right, under the lending agreement,
      to terminate the loan and recover the securities from the borrower with
      prior notice. The Fund is required to return the cash collateral to the
      borrower and could suffer a loss if the value of the collateral, as
      invested, has declined.

2.    Management Agreement

Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary of
UniCredit, manages the Fund's portfolio. Management fees are calculated daily at
the annual rate of 0.65% of the Fund's average daily net assets up to $1
billion, 0.60% of the next $4 billion and 0.55% on assets over $5 billion. For
the year ended August 31, 2011, the effective management fee (excluding waivers
and/or assumption of expenses) was equivalent to 0.65% of the Fund's average
daily net assets.

PIM has contractually agreed to limit ordinary operating expenses of the Fund to
the extent required to reduce Fund expenses to 1.25%, 2.15%, and 0.90% of the
average daily net assets attributable to Class A, Class C, and Class Y shares,
respectively. Expenses waived and reimbursed during the year ended August 31,
2011 are reflected on the Statement of Operations. These expense limitations are
in effect through January 1, 2012. There can be no assurance that PIM will
extend the expense limitation agreement for a class of shares beyond the date
referred to above.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund as administrative reimbursements. Included in
"Due to affiliates" reflected on the Statement of Assets and Liabilities is $923
in management fees, administrative costs and certain other reimbursements
payable to PIM at August 31, 2011.

                Pioneer Disciplined Growth Fund | Annual Report | 8/31/11     31


3.    Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially
all transfer agent and shareowner services to the Fund at negotiated rates.

In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by
PIMSS related to shareholder communications activities such as proxy and
statement mailings, outgoing phone calls and omnibus relationship contracts. For
the year ended August 31, 2011, such out-of-pocket expenses by class of shares
were as follows:



--------------------------------------------------------------------------------
Shareholder Communications:
--------------------------------------------------------------------------------
                                                                       
Class A                                                                   $5,092
Class C                                                                    1,635
Class Y                                                                    1,450
--------------------------------------------------------------------------------
   Total                                                                  $8,177
================================================================================


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $3,369 in transfer agent fees and out-of-pocket reimbursements
payable to PIMSS at August 31, 2011.

4.    Distribution Plan

The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the
Investment Company Act of 1940 with respect to its Class A and Class C shares.
Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net assets
attributable to Class A shares as compensation for personal services and/or
account maintenance services or distribution services with regard to Class A
shares. Pursuant to the Plan, the Fund also pays PFD 1.00% of the average daily
net assets attributable to Class C shares. The fee for Class C shares consists
of a 0.25% service fee and a 0.75% distribution fee paid as compensation for
personal services and/or account maintenance services or distribution services
with regard to Class C shares. Included in "Due to affiliates" reflected on the
Statement of Assets and Liabilities is $71 in distribution fees payable to PFD
at August 31, 2011.

In addition, redemptions of each class of shares (except Class Y shares) may be
subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be
imposed on redemptions of certain net asset value purchases of Class A shares
within 12 months of purchase. Redemptions of Class C shares within one year of
purchase are subject to a CDSC of 1.00%, based on the lower of cost or market
value of shares being redeemed. Shares purchased as part of an exchange remain
subject to any CDSC that applied to the original purchase of those shares. There
is no CDSC for Class Y shares. Proceeds from the CDSCs are paid to PFD. For the
year ended August 31, 2011, CDSCs in the amount of $81 were paid to PFD.

events and transactions for potential recognition or disclosure and has
determined that there were no subsequent events requiring recognition or
disclosure in the financial statements.

Report of Independent Registered Public Accounting Firm

To the Trustees of Pioneer Series Trust V and
Shareholders of Pioneer Disciplined Growth Fund:
--------------------------------------------------------------------------------
We have audited the accompanying statement of assets and liabilities of Pioneer
Disciplined Growth Fund (the Fund) (one of the portfolios constituting Pioneer
Series Trust V), including the schedule of investments, as of August 31, 2011,
and the related statement of operations for the year then ended, the statements
of changes in net assets for each of the two years in the period then ended, and
the financial highlights for each of the periods indicated therein. These
financial statements and financial highlights are the responsibility of the
Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Fund's internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Fund's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of August 31, 2011, by correspondence with the custodian and
brokers or by other appropriate auditing procedures where replies from brokers
were not received. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer Disciplined Growth Fund at August 31, 2011, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each of
the periods indicated therein, in conformity with U.S. generally accepted
accounting principles.

President's Letter

Dear Shareowner,

The U.S. economy went through a soft patch in the first half of 2011, and the
second half of the year, so far, has been highlighted by the U.S. government's
battle over the debt ceiling and Standard & Poor's downgrade of the U.S.
Treasury's credit rating from the top rating of "AAA" for the first time in
history. The markets reacted quite negatively to the credit downgrade, and there
is concern about the strength of the global economy going forward.

Pioneer is cautiously optimistic that the U.S. economy will see moderate
economic growth over the balance of 2011, though at a slower pace than we had
expected earlier this year. While housing and employment remain weak, the
private sector shows signs of slow but steady improvement, led by higher capital
investment, solid exports, and improved consumption. At the same time, the risks
to growth remain substantial, including high unemployment, continued delays in
the housing sector's recovery, and the fiscal drag of U.S. federal and state
budget cuts.

The difficult recovery process has been accompanied by wide market swings. While
this is a challenging environment, our investment professionals continue to
focus on finding good opportunities to invest in both equity and bond markets
using the same disciplined approach Pioneer has used since 1928. Our approach is
to identify undervalued individual securities with the greatest potential for
success, carefully weighing risk against reward. Our teams of investment
professionals continually monitor and analyze the relative valuations of
different sectors and securities globally to help build portfolios that we
believe can help you achieve your investment goals.

At Pioneer, we have long advocated the benefits of staying diversified and
investing for the long term. The strategy has generally performed well for many
investors. Our advice, as always, is to work closely with a trusted financial
advisor to discuss your goals and work together to develop an investment
strategy that meets your individual needs. There is no single best strategy that
works for every investor.

investing by consulting with your financial advisor or visiting us online at

you for investing with Pioneer.

Portfolio Management Discussion | 8/31/11

In the following interview, Paul Cloonan, head of equity research, U.S., and
Ashesh ("Ace") Savla, vice president and senior quantitative research analyst,
discuss the market environment and other factors that affected Pioneer
Disciplined Value Fund's performance over the 12 months ended August 31, 2011.
Mr. Cloonan and Mr. Savla are responsible for the day-to-day management of the
Fund.

Q     How would you characterize the investment environment for equities, over
      the 12-month period ended August 31, 2011?

A     The U.S. equity market continued to advance through April 2011, driven by
      strong corporate earnings and attractive equity valuations when compared
      with many other asset classes. With short-term interest rates at
      historically low levels and abundant liquidity due to the Federal Reserve
      Board's (the Fed's) "quantitative easing" program, investors became less
      risk-averse and increased their exposure to equities. In the last few
      months of the 12-month period, however, the equity market traded below the
      level it reached in late April 2011, due to increasing macroeconomic risk
      factors such as slowing economic growth, the U.S. debt ceiling and fiscal
      debates, the debt crisis in Europe, and tighter monetary policy in China
      as well as other countries. Corporate earnings have continued to be
      strong, but there is risk that earnings growth could slow as a result of
      the macro factors. Despite the macro-related concerns seen late in the
      period, the Russell 1000 Value Index, the Fund's benchmark, delivered a
      total return of 14.37% for the 12 months ended August 31, 2011. The
      Russell 1000 Value Index lagged the 23.96% return of the Russell 1000
      Growth Index during the same 12-month period, primarily due to the larger
      weighting of the financials sector in the Russell 1000 Value Index. The
      financials sector has been lagging other sectors due to regulatory risks,
      concerns about credit risk, sluggish loan growth and other factors.

Q     How did the Fund perform over the 12 months ended August 31, 2011?

A     Pioneer Disciplined Value Fund Class A shares returned 13.69% at net asset
      value over the 12 months ended August 31, 2011, while the Fund's
      benchmark, the Russell 1000 Value Index, returned 14.37%. During the same
      period, the average return of the 485 mutual funds in Lipper's Large-Cap
      Value Funds category was 13.56%.

4     Pioneer Disciplined Value Fund | Annual Report | 8/31/11


Q     The Fund slightly underperformed the Russell 1000 Value Index over the
      full 12-month period ended August 31, 2011. Could you highlight some of
      the factors behind the Fund's underperformance relative to the benchmark?

A     As designed, the Fund's performance is derived primarily from individual
      stock selection. The underperformance of the Fund during the 12-month
      period did not come from any clear macroeconomic factor or industry bias,
      but rather from specific individual securities that did not perform as
      well as the Russell 1000 Value Index benchmark.

Q     What sector allocations or portfolio holdings disappointed during the
      12-month period ended August 31, 2011?

A     Underperforming industries during the period included pharmaceuticals &
      biotechnology, household & personal products, and semiconductors &
      semiconductor equipment. In pharmaceuticals, the Fund's large-cap holdings
      in Pfizer, Merck, and Bristol-Myers Squibb lagged the returns of biotech
      stocks as well as mid-cap pharmaceutical stocks. In household & personal
      products, the Fund's performance was hurt by not owning Procter & Gamble
      (the largest stock in this industry group) during a period when the
      company outperformed most other stocks in the group. In the semiconductor
      and semiconductor equipment group, the Fund's positions in ASML and
      Applied Materials underperformed relative to the rest of the industry.
      Investor sentiment towards semiconductor equipment stocks turned negative
      following a slowdown in near-term order growth as companies became more
      cautious about adding capacity due to a weaker outlook for global growth.

Q     Given the fairly negative economic news over the past few months, what is
      your outlook for the remainder of 2011?

A     We remain optimistic about the outlook for equities, although some of the
      macro issues addressed in the first question above may provide headwinds
      for the equity market in the near term. Our optimism on the longer-term
      outlook for equities is supported by attractive equity valuations relative
      to other asset classes and our assumption that the economy will continue
      to grow. In addition, corporate balance sheets and cash flow are strong,
      which may lead to increased merger-and-acquisition activity, share
      repurchases and dividend increases.

      We will continue to focus our efforts on stock picking, which we believe
      is the Fund's key competitive advantage and primary performance driver.
      Our approach to stock picking emphasizes bottom-up, fundamental analysis.
      We believe our approach is durable and repeatable and can deliver
      reasonable investment results across the business cycle, and in a variety
      of market conditions.

Please refer to the Schedule of Investments on pages 14-19 for a full listing of
Fund securities.

Small- and mid-sized companies may offer the potential for higher returns but
are also subject to greater short-term price fluctuations than larger, more
established companies. The Fund invests in a limited number of securities, and,
as a result, the Fund's performance may be more volatile than the performance of
other funds holding more securities. At times, the Fund's investments may
represent industries or industry sectors that are interrelated or have common
risks, making it more susceptible to any economic, political, or regulatory
developments or other risks affecting those industries and sectors.

These risks may increase share price volatility.

the performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

NAV results represent the percent change in net asset value per share. Returns
would have been lower had sales charges been reflected. POP returns reflect
deduction of maximum 5.75% sales charge. All results are historical and assume
the reinvestment of dividends and capital gains. Other share classes are
available for which performance and expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers may
not be in effect for all funds. Certain fee waivers are contractual through a
specified period. Otherwise, fee waivers can be rescinded at any time. See the
prospectus and financial statements for more information.

The net expense ratio reflects the contractual expense limitation currently in
effect through January 1, 2012, for Class A shares. There can be no assurance
that Pioneer will extend the expense limitation beyond such time. Please see the
prospectus and financial statements for more information.

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Fund distributions or the redemption of Fund
shares.

The performance data quoted represents past performance, which is no guarantee

shares, when redeemed, may be worth more or less than their original cost.

The performance shown for Class Y shares for the period prior to the inception
of Class Y shares on July 31, 2008, is based on the net asset value performance
of the Fund's Class A shares, which has not been restated to reflect any
differences in expenses, including Rule 12b-1 fees applicable to Class A shares.
Since fees for Class A shares generally are higher than those of Class Y shares,
the performance of Class Y shares prior to their inception would have been
higher than the performance shown.

Class Y shares are not subject to sales charges and are available for limited
groups of eligible investors, including institutional investors. All results are
historical and assume the reinvestment of dividends and capital gains. Other
share classes are available for which performance and expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers may
not be in effect for all funds. Certain fee waivers are contractual through a
specified period. Otherwise, fee waivers can be rescinded at any time. See the
prospectus and financial statements for more information.

The net expense ratio reflects the contractual expense limitation currently in
effect through January 1, 2012, for Class Y shares. There can be no assurance
that Pioneer will extend the expense limitation beyond such time. Please see the
prospectus and financial statements for more information.

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Fund distributions or the redemption of Fund
shares.

Comparing Ongoing Fund Expenses

As a shareowner in the Fund, you incur two types of costs:

(1)   ongoing costs, including management fees, distribution and/or service
      (12b-1) fees, and other Fund expenses; and

(2)   transaction costs, including sales charges (loads) on purchase payments.

This example is intended to help you understand your ongoing expenses (in
dollars) of investing in the Fund and to compare these costs with the ongoing
costs of investing in other mutual funds. The example is based on an investment
of $1,000 at the beginning of the Fund's latest six-month period and held
throughout the six months.

Using the Tables
--------------------------------------------------------------------------------
Actual Expenses

The first table below provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period as
follows:

(1)   Divide your account value by $1,000
      Example: an $8,600 account value [divided by] $1,000 = 8.6

(2)   Multiply the result in (1) above by the corresponding share class's number
      in the third row under the heading entitled "Expenses Paid During Period"
      to estimate the expenses you paid on your account during this period.

During Period*
--------------------------------------------------------------------------------


*     Expenses are equal to the Fund's annualized expense ratio plus the expense
      ratios of the underlying funds. These combined totals were 1.27%, 2.17%
      and 0.92% for Class A, Class C and Class Y shares, respectively. These
      combined ratios were multiplied by the average account value over the
      period, and then multiplied by 184/365 (to reflect the one-half year
      period) to calculate the "Expenses Paid During Period" in the table above.

Hypothetical Example for Comparison Purposes

The table below provides information about hypothetical account values and
hypothetical expenses based on the Fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not the Fund's actual
return. The hypothetical account values and expenses may not be used to estimate
the actual ending account balance or expenses you paid for the period.

You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the tables are meant to highlight your
ongoing costs only and do not reflect any transaction costs, such as sales
charges (loads) that are charged at the time of the transaction. Therefore, the
table below is useful in comparing ongoing costs only and will not help you
determine the relative total costs of owning different funds. In addition, if
these transaction costs were included, your costs would have been higher.

               similar securities, interest rates, prepayment speeds, credit
               risk, etc.)
  Level 3 --   significant unobservable inputs (including the Fund's own
               assumptions in determining fair value of investments)

Generally, equity securities are categorized as Level 1, fixed income securities
and senior loans as Level 2 and securities valued using fair value methods (see

Notes to Financial Statements | 8/31/11

1.    Organization and Significant Accounting Policies

Pioneer Disciplined Value Fund, formerly Pioneer Research Value Fund (the Fund),
is one of four portfolios comprising Pioneer Series Trust V, a Delaware
statutory trust. The Fund is registered under the Investment Company Act of 1940
as a diversified, open-end management investment company. The Fund was organized
on October 12, 2005, and commenced operations on December 15, 2005. Pioneer
Investment Management Inc. (PIM), the Fund's investment adviser, paid all
organizational costs of the Fund. The Fund's investment objective is long-term
capital growth.

The Fund offers three classes of shares designated as Class A, Class C and Class
Y shares. Class C shares were first publicly offered on July 17, 2008. Class Y
shares were first publicly offered on July 31, 2008. Each class of shares
represents an interest in the same portfolio of investments of the Fund and has
identical rights (based on relative net asset values) to assets and liquidation
proceeds. Share classes can bear different rates of class-specific fees and
expenses such as transfer agent and distribution fees. Differences in
class-specific fees and expenses will result in differences in net investment
income and, therefore, the payment of different dividends from net investment
income earned by each class. The Amended and Restated Declaration of Trust of
the Fund gives the Board the flexibility to specify either per-share voting or
dollar-weighted voting when submitting matters for shareholder approval. Under
per-share voting, each share of a class of the Fund is entitled to one vote.
Under dollar-weighted voting, a shareholder's voting power is determined not by
the number of shares owned, but by the dollar value of the shares on the record
date. Each share class has exclusive voting rights with respect to matters
affecting only that class, including with respect to the distribution plan for
that class. There is no distribution plan for Class Y shares.

Small and mid-sized companies may offer the potential for higher returns, but
are also subject to greater short-term price fluctuations than larger, more
established companies. The Fund's prospectus contains information regarding the
Fund's principal risks. Please refer to that document when considering the
Fund's principal risks.

The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the Fund
to, among other things, make estimates and assumptions that affect the reported
amounts of assets and liabilities, the disclosure of contingent assets and
liabilities at the date of the financial statements, and the reported amounts

                 Pioneer Disciplined Value Fund | Annual Report | 8/31/11     27


of income, expenses and gain or loss on investments during the reporting period.
Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements, which are consistent with
those policies generally accepted in the investment company industry:

A.    Security Valuation

      Security transactions are recorded as of trade date. The net asset value
      of the Fund is computed once daily, on each day the New York Stock
      Exchange (NYSE) is open, as of the close of regular trading on the NYSE.
      In computing the net asset value, securities that have traded on an
      exchange are valued at the last sale price on the principal exchange where
      they are traded. Securities that have not traded on the date of valuation,
      or securities for which sale prices are not available, generally are
      valued at the mean between the last bid and asked prices. Securities for
      which market prices and/or quotations are not readily available or are
      considered to be unreliable are valued using fair value methods pursuant
      to procedures adopted by the Board of Trustees.

      Trading in foreign securities is substantially completed each day at
      various times prior to the close of the NYSE. The values of such
      securities used in computing the net asset value of the Fund's shares are
      determined as of such times.

      The Fund may use fair value methods if it is determined that a significant
      event has occurred after the close of the exchange or market on which the
      security trades and prior to the determination of the Fund's net asset
      value. Thus, the valuation of the Fund's securities may differ from
      exchange prices.

      At August 31, 2011, there were no securities that were valued using fair
      value methods (other than securities that were valued using prices
      supplied by independent pricing services). Inputs used when applying fair
      value methods to value a security may include credit ratings, the
      financial condition of the company, current market conditions and
      comparable securities. Short-term fixed income securities with remaining
      maturities of sixty days or less generally are valued at amortized cost.
      Money market mutual funds are valued at net asset value.

      Dividend income is recorded on the ex-dividend date, except that certain
      dividends from foreign securities where the ex-dividend date may have
      passed are recorded as soon as the Fund becomes aware of the ex-dividend
      data in the exercise of reasonable diligence. Interest income is recorded
      on the accrual basis. Dividend and interest income are reported net of
      unrecoverable foreign taxes withheld at the applicable country rates.

      Gains and losses on sales of investments are calculated on the identified
      cost method for both financial reporting and federal income tax purposes.

28     Pioneer Disciplined Value Fund | Annual Report | 8/31/11


B.    Federal Income Taxes

      It is the Fund's policy to comply with the requirements of the Internal
      Revenue Code applicable to regulated investment companies and to
      distribute all of its taxable income and net realized capital gains, if
      any, to its shareowners. Therefore, no federal income tax provision is
      required. Tax years for the prior three fiscal years are subject to
      examination by tax authorities.

      The amounts and characterizations of distributions to shareowners for
      financial reporting purposes are determined in accordance with federal
      income tax rules. Therefore, the sources of the Fund's distributions may
      be shown in the accompanying financial statements as from or in excess of
      net investment income or as from net realized gain on investment
      transactions, or as from paid-in capital, depending on the type of
      book/tax differences that may exist.

      At August 31, 2011, the Fund reclassified $70 to decrease undistributed
      net investment income and $70 to increase accumulated net realized gain,
      to reflect permanent book/tax differences. The reclassification has no
      impact on the net assets of the Fund and presents the Fund's capital
      accounts on a tax basis.

      Under the recently enacted Regulated Investment Company Modernization Act
      of 2010, the Fund will be permitted to carry forward capital losses
      incurred in taxable years beginning after December 22, 2010 for an
      unlimited period. However, any losses incurred during those future years
      will be required to be utilized prior to the losses incurred in
      pre-enactment tax years. As a result of this ordering rule, pre-enactment
      capital loss carryforwards may be more likely to expire unused.
      Additionally, post-enactment capital losses that are carried forward will
      retain their character as either short-term or long-term capital losses
      rather than being considered all short-term as under previous law.

      The tax character of distributions paid during the years ended August 31,
      2011 and August 31, 2010 was as follows:



--------------------------------------------------------------------------------
                                                             2011           2010
--------------------------------------------------------------------------------
                                                                
Distributions paid from:
Ordinary income                                        $2,703,287     $1,232,058
Long-term capital gain                                    724,285             --
--------------------------------------------------------------------------------
   Total                                               $3,427,572     $1,232,058

      The following shows the components of distributable earnings on a federal
      income tax-basis at August 31, 2011:



--------------------------------------------------------------------------------
                                                                           2011
--------------------------------------------------------------------------------
                                                                  
Distributable earnings:
Undistributed ordinary income                                        $1,385,456
Undistributed long-term gain                                          1,641,914
Net unrealized loss                                                    (856,975)
--------------------------------------------------------------------------------
   Total                                                             $2,170,395
================================================================================


      The difference between book-basis and tax-basis unrealized depreciation is
      attributable to the tax deferral of losses on wash sales.

C.    Fund Shares

      The Fund records sales and repurchases of its shares as of trade date.
      Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the
      Fund and a wholly owned indirect subsidiary of UniCredit S.p.A.
      (UniCredit), earned $1,369 in underwriting commissions on the sale of
      Class A shares during the year ended August 31, 2011.

D.    Class Allocations

      Income, common expenses and realized and unrealized gains and losses are
      calculated at the Fund level and allocated daily to each class of shares
      based on its respective percentage of adjusted net assets at the beginning
      of the day.

      Distribution fees are calculated based on the average daily net asset
      value attributable to Class A and Class C shares of the Fund, respectively
      (see Note 4). Class Y shares do not pay distribution fees. All expenses
      and fees are paid to the transfer agent, Pioneer Investment Management
      Shareholder Services, Inc. (PIMSS), for its services are allocated among
      the classes of shares based on the number of accounts in each class and
      the ratable allocation of related out-of-pocket expenses (see Note 3).

      Distributions to shareowners are recorded as of the ex-dividend date.
      Distributions paid by the Fund with respect to each class of shares are
      calculated in the same manner and at the same time, except that net
      investment income dividends to Class A, Class C, and Class Y shares can
      reflect different transfer agent and distribution expense rates.

E.    Securities Lending

      The Fund lends securities in its portfolio to certain broker-dealers or
      other institutional investors. When entering into a securities loan
      transaction, the Fund typically receives cash collateral from the borrower
      equal to at least the value of the securities loaned, which is invested in
      temporary investments.

30     Pioneer Disciplined Value Fund | Annual Report | 8/31/11


      Credit Suisse AG, New York Branch, as the Fund's securities lending agent,
      manages the Fund's securities lending collateral. The income earned on the
      investment of collateral is shared with the borrower and the lending agent
      in payment of any rebate due to the borrower with respect to the
      securities loan, and in compensation for the lending agent's services to
      the Fund. The Fund also continues to receive payments in lieu of dividends
      or interest on the securities loaned. Gain or loss on the value of the
      loaned securities that may occur during the term of the loan will be for
      the account of the Fund. The amount of the collateral is required to be
      adjusted daily to reflect any price fluctuation in the value of the loaned
      securities. If the required market value of the collateral is less than
      the value of the loaned securities, the borrower is required to deliver
      additional collateral for the account of the Fund prior to the close of
      business on that day. The Fund has the right, under the lending agreement,
      to terminate the loan and recover the securities from the borrower with
      prior notice. The Fund is required to return the cash collateral to the
      borrower and could suffer a loss if the value of the collateral, as
      invested, has declined.

2.    Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's
portfolio. Management fees are calculated daily at the annual rate of 0.65% of
the Fund's average daily net assets up to $1 billion, 0.60% of the next $4
billion and 0.55% on assets over $5 billion. For the year ended August 31, 2011,
the effective management fee (excluding waivers and/or assumption of expenses)
was equivalent to 0.65% of the Fund's average daily net assets.

PIM has contractually agreed to limit ordinary operating expenses of the Fund to
the extent required to reduce Fund expenses to 1.25%, 2.15%, and 0.90% of the
average daily net assets attributable to Class A, Class C, and Class Y shares,
respectively. Expenses waived and reimbursed during the year ended August 31,
2011 are reflected on the Statement of Operations. These expense limitations are
in effect through January 1, 2012 for all classes. There can be no assurance
that PIM will extend the expense limitation agreement for a class of shares
beyond the date referred to above.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund as administrative reimbursements. Included in
"Due to affiliates" reflected on the Statement of Assets and Liabilities is $883
in management fees, administrative costs and certain other reimbursements
payable to PIM at August 31, 2011.

3.    Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially
all transfer agent and shareowner services to the Fund at negotiated rates.

                 Pioneer Disciplined Value Fund | Annual Report | 8/31/11     31


In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by
PIMSS related to shareholder communications activities such as proxy and
statement mailings, outgoing phone calls and omnibus relationship contracts. For
the year ended August 31, 2011, such out-of-pocket expenses by class of shares
were as follows:

4.    Distribution Plan

The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the
Investment Company Act of 1940 with respect to its Class A and Class C shares.
Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net assets
attributable to Class A shares as compensation for personal services and/or
account maintenance services or distribution services with regard to Class A
shares. Pursuant to the Plan, the Fund also pays PFD 1.00% of the average daily
net assets attributable to Class C shares. The fee for Class C shares consists
of a 0.25% service fee and a 0.75% distribution fee paid as compensation for
personal services and/or account maintenance services or distribution services
with regard to Class C shares. Included in "Due to affiliates" reflected on the
Statement of Assets and Liabilities is $28 in distribution fees payable to PFD
at August 31, 2011.

In addition, redemptions of each class of shares (except Class Y shares) may be
subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be
imposed on redemptions of certain net asset value purchases of Class A shares
within 12 months of purchase. Redemptions of Class C shares within one year of
purchase are subject to a CDSC of 1.00%, based on the lower of cost or market
value of shares being redeemed. Shares purchased as part of an exchange remain
subject to any CDSC that applied to the original purchase of those shares. There
is no CDSC for Class Y shares. Proceeds from the CDSCs are paid to PFD. For the
year ended August 31, 2011, CDSCs in the amount of $80 were paid to PFD.

Report of Independent Registered Public Accounting Firm

To the Trustees of Pioneer Series Trust V and
Shareholders of Pioneer Disciplined Value Fund:
--------------------------------------------------------------------------------
We have audited the accompanying statement of assets and liabilities of Pioneer
Disciplined Value Fund (the Fund) (one of the portfolios constituting Pioneer
Series Trust V), including the schedule of investments, as of August 31, 2011,
and the related statement of operations for the year then ended, the statements
of changes in net assets for each of the two years in the period then ended, and
the financial highlights for each of the periods indicated therein. These
financial statements and financial highlights are the responsibility of the
Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Fund's internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Fund's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of August 31, 2011, by correspondence with the custodian and
brokers or by other appropriate auditing procedures where replies from brokers
were not received. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer Disciplined Value Fund at August 31, 2011, the results of its operations
for the year then ended, the changes in its net assets for each of the two years
in the period then ended, and the financial highlights for each of the periods
indicated therein, in conformity with U.S. generally accepted accounting
principles.

President's Letter

Dear Shareowner,

The U.S. economy went through a soft patch in the first half of 2011, and the
second half of the year, so far, has been highlighted by the U.S. government's
battle over the debt ceiling and Standard & Poor's downgrade of the U.S.
Treasury's credit rating from the top rating of "AAA" for the first time in
history. The markets reacted quite negatively to the credit downgrade, and
there is concern about the strength of the global economy going forward.

Pioneer is cautiously optimistic that the U.S. economy will see moderate
economic growth over the balance of 2011, though at a slower pace than we had
expected earlier this year. While housing and employment remain weak, the
private sector shows signs of slow but steady improvement, led by higher
capital investment, solid exports, and improved consumption. At the same time,
the risks to growth remain substantial, including high unemployment, continued
delays in the housing sector's recovery, and the fiscal drag of U.S. federal
and state budget cuts.

The difficult recovery process has been accompanied by wide market swings.
While this is a challenging environment, our investment professionals continue
to focus on finding good opportunities to invest in both equity and bond
markets using the same disciplined approach Pioneer has used since 1928. Our
approach is to identify undervalued individual securities with the greatest
potential for success, carefully weighing risk against reward. Our teams of
investment professionals continually monitor and analyze the relative
valuations of different sectors and securities globally to help build
portfolios that we believe can help you achieve your investment goals.

At Pioneer, we have long advocated the benefits of staying diversified and
investing for the long term. The strategy has generally performed well for many
investors. Our advice, as always, is to work closely with a trusted financial
advisor to discuss your goals and work together to develop an investment
strategy that meets your individual needs. There is no single best strategy
that works for every investor.

Portfolio Management Discussion | 8/31/11

In the following interview, Marco Pirondini, head of equities, U.S., at Pioneer
and portfolio manager of Pioneer Global Equity Fund, discusses the factors that
influenced the Fund's performance during the 12-month period ended August 31,
2011.

Q  How did the Fund perform over the 12-month period ended August 31, 2011?

A  In a mixed period for the global equity markets, Pioneer Global Equity Fund
   Class A shares returned 10.48% at net asset value over the 12 months ended
   August 31, 2011, while the Fund's benchmark, the Morgan Stanley Capital
   International (MSCI)* World Index, returned 15.06%. Over the same period,
   the average return of the 125 mutual funds in Lipper's Global Large-Cap
   Core Funds category was 13.52%.

Q  How would you characterize the global equity markets over the Fund's most
   recent fiscal year ended August 31, 2011?

A  The past 12 months featured two sharply contrasting periods of market
   performance. Earlier in the period global stock markets rallied sharply,
   spurred by the U.S. Federal Reserve Board's (the Fed's) announcement of a
   second round of quantitative easing (QE2). The positive impact that market
   watchers felt QE2 would have on liquidity and asset prices helped to push
   stock prices up. The market upturn began in early September 2010, and
   continued through June of 2011. Beginning in July 2011, however, a number
   of unfavorable events short-circuited the rally. They included the
   termination of QE2, the cumulative effect of the tragic natural disasters
   in Japan, continued severe problems with European sovereign debt, and
   downward revisions in the outlook for growth in major developed economies.

Q  Would you review the Fund's overall investment approach during the 12 months
   ended August 31, 2011?

A  In managing the Fund, we examine mid- and large-capitalization stocks
   worldwide, including those in emerging markets. From there, we build a
   diversified portfolio. In selecting securities for the Fund, we look for
   "growth at a reasonable price," and so there is a strong value component to
   our analysis. We seek to invest the Fund in companies that are not only
   benefiting from operating efficiencies as reflected in factors including
   increased market share and revenues, but also those that employ their
   capital efficiently. In particular, we emphasize strong free cash flow,
   because it provides companies with the flexibility to make share buybacks,
   reinvest in their businesses, make acquisitions and raise dividends. We
   also look for stocks with attractive dividend yields as well as those
   trading at lower-than-market valuations.

   Finally, we attempt to assess not only the potential price gains for each
   stock but also the potential for a decline in price if circumstances become
   unfavorable. We prefer stocks with the highest potential upside relative to
   their downside.

Q  What investment strategies or individual securities helped and/or hurt the
   Fund's performance over the 12 months ended August 31, 2011?

A  During the period, the Fund's performance was aided by our gradual
   repositioning of the portfolio toward increased holdings in the emerging
   markets and our moves to hedge the Fund's currency exposure. While the
   Fund's overall weighting to emerging markets ended up being a minor drag on
   benchmark-relative returns, particularly in Asia (ex-Japan), stock
   selection in the emerging markets was a strong positive contributor to
   relative performance.

   The Fund's holdings in the industrials sector, especially in Schneider
   Industries, also helped performance. We sold the Fund's position earlier
   this year in order to capture price appreciation. In addition, a Fund
   position in Irish government bonds that we purchased during the period
   contributed significantly. For diversification purposes, we bought the
   bonds as a way of generating exposure for the Fund to the European
   financial industry, without holding European bank stocks, which we viewed
   as too risky. Among the nations along the euro-zone "periphery" that have
   experienced significant budgetary problems over the past several years, we
   see Ireland as a country that is resilient and competitive economically,
   with export levels that have been improving. During the 12-month period
   ended August 31, 2011, yields on the Fund's Irish government bond holdings
   declined significantly, thus boosting the prices of the bonds, and the
   Fund's return.


                      Pioneer Global Equity Fund | Annual Report | 8/31/11     5


   Another holding that contributed to performance was the Fund's position in
   ITOCHU, a cyclical company that performed well in spite of the earthquake
   and tsunami in Japan. Investors came to believe that based on its healthy
   import/export business, ITOCHU could benefit in the medium term from
   Japan's extensive reconstruction efforts.

   Overall, our conservative positioning during the first half of the Fund's
   fiscal year subtracted from returns, as we never believed that the Fed's
   QE2 program alone would improve U.S. economic performance in a sustained
   fashion. However, earlier in the period consumer spending in Europe and the
   United States proved stronger than expected, and our cautious investment
   stance regarding the consumer discretionary sector hurt the Fund's
   performance. Specific detractors from performance during the 12-month
   period came mainly from holdings in consumer discretionary and also in
   materials. Within consumer discretionary, the Fund's position in the
   Brazilian real estate developer Gafisa hurt relative return as investors
   worried that interest rate hikes by the Brazilian central bank would slow
   the economy there. The Fund continues to hold the stock as short-term rates
   in Brazil are now being reduced, and many market watchers see improved
   prospects for consumer companies such as Gafisa.

   In the materials area, holdings in Sino-Forest had a significant negative
   impact on the Fund's one-year return. Sino-Forest, a Chinese forestry
   company, came under investigation by Canadian securities authorities during
   the summer of 2011. Company officials have been accused of exaggerating
   revenues and the firm's CEO was forced to resign. Trading in Sino-Forest
   shares has been suspended until January 2012, when the results of a fraud
   investigation are due to be released.

Q  What is your outlook and how is it reflected in the Fund's positioning as the
   Fund's new fiscal year begins?

A  Investors have been focused for some time on the sovereign-debt problems in
   Europe that first emerged with the Greek fiscal crisis in 2010 and
   subsequently spread to peripheral European countries, and beyond. We think
   that the European situation is solvable, but only if the region's leaders
   summon the political will to issue sufficient Eurobonds to ease the crisis,
   and accelerate political and fiscal integration there. We think the
   solutions are possible longer-term, but at the same time we are concerned
   that the European crisis could drag on for years. In addition, we believe
   that developed economies will continue to be structurally weak and that
   emerging market countries should prosper by comparison. We look for slow,
   but steady economic growth in the United States.

   Though our biggest concerns regarding developed markets are focused on the
   European side, we also find that valuations are significantly compressed.
   In light of that, in recent weeks we have added some severely discounted

   European stocks to the Fund, along with hedged currency positions designed
   to offset any further deterioration in the euro.

Investing in foreign and/or emerging markets securities involves certain risks,
including risks relating to interest rates, currency exchange rates, economic
and political conditions. Investments in mid-sized companies may offer the
potential for higher returns, but are also subject to greater short-term price
fluctuations than larger, more established companies. The Fund is
non-diversified and invests in a limited number of securities and, as a result,
the Fund's performance may be more volatile than the performance of funds
holding more securities. At times, the Fund's investments may represent
industries or industry sectors that are interrelated or have common risks,
making it more susceptible to any economic, political, or regulatory
developments or other risks affecting those industries and sectors.

These risks may increase share price volatility.

Past performance is no guarantee of future results, and there is no guarantee
that market forecasts discussed will be realized.

The Morgan Stanley Capital International (MSCI) World Index measures the
performance of stock markets in the developed world. Index returns are
calculated monthly, assume reinvestment of dividends and, unlike Fund returns,
do not reflect any fees, expenses or sales charges. It is not possible to
invest directly in an index.

The index defined here pertains to the "Value of $10,000 Investment" and "Value
of $5 Million Investment" charts on pages 10-13.

Call 1-800-225-6292 or visit us.pioneerinvestments.com for the most recent
month-end performance results. Current performance may be lower or higher than
the performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

NAV results represent the percent change in net asset value per share. Returns
would have been lower had sales charges been reflected. POP returns reflect
deduction of maximum 5.75% sales charge. All results are historical and assume
the reinvestment of dividends and capital gains. Other share classes are
available for which performance and expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers
may not be in effect for all funds. Certain fee waivers are contractual through
a specified period. Otherwise, fee waivers can be rescinded at any time. See
the prospectus and financial statements for more information.

The net expense ratio reflects contractual expense limitations currently in
effect through 1/1/12 for Class A shares. There can be no assurance that
Pioneer will extend the expense limitations beyond such time. Please see the
prospectus and financial statements for more information.

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Fund distributions or the redemption of Fund
shares.

Call 1-800-225-6292 or visit us.pioneerinvestments.com for the most recent
month-end performance results. Current performance may be lower or higher than
the performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

Class C shares held for less than one year are also subject to a 1% contingent
deferred sales charge (CDSC). "If Held" results represent the percent change in
net asset value per share. Returns would have been lower had sales charges been
reflected. All results are historical and assume the reinvestment of dividends
and capital gains. Other share classes are available for which performance and
expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers
may not be in effect for all funds. Certain fee waivers are contractual through
a specified period. Otherwise, fee waivers can be rescinded at any time. See
the prospectus and financial statements for more information.

The net expense ratio reflects contractual expense limitations currently in
effect through 1/1/12 for Class C shares. There can be no assurance that
Pioneer will extend the expense limitations beyond such time. Please see the
prospectus and financial statements for more information.

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Fund distributions or the redemption of Fund
shares.

the performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

Performance shown for periods prior to the inception of the Fund's Class Y
shares on December 31, 2008 reflects the NAV performance of the Fund's Class A
shares. The performance does not reflect differences in expenses, including the
Rule 12b-1 fees applicable to Class A shares. Since fees for Class A shares are
generally higher than those of Class Y shares, the performance for Class Y
shares prior to their inception would have been higher than the performance
shown. Class Y shares are not subject to sales charges and are available for
limited groups of eligible investors, including institutional investors. All
results are historical and assume the reinvestment of dividends and capital
gains. Other share classes are available for which performance and expenses
will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers
may not be in effect for all funds. Certain fee waivers are contractual through
a specified period. Otherwise, fee waivers can be rescinded at any time. See
the prospectus and financial statements for more information.

The net expense ratio reflects contractual expense limitations currently in
effect through 1/1/12 for Class Y shares. There can be no assurance that
Pioneer will extend the expense limitations beyond such time. Please see the
prospectus and financial statements for more information.

Comparing Ongoing Fund Expenses

As a shareowner in the Fund, you incur two types of costs:

(1)   ongoing costs, including management fees, distribution and/or service
      (12b-1) fees, and other Fund expenses; and

(2)   transaction costs, including sales charges (loads) on purchase payments
      and redemption fees.

This example is intended to help you understand your ongoing expenses (in
dollars) of investing in the Fund and to compare these costs with the ongoing
costs of investing in other mutual funds. The example is based on an investment
of $1,000 at the beginning of the Fund's latest six-month period and held
throughout the six months.

Using the Tables
--------------------------------------------------------------------------------
Actual Expenses

The first table below provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period as
follows:

(1)   Divide your account value by $1,000
      Example: an $8,600 account value [divided by] $1,000 = 8.6

(2)   Multiply the result in (1) above by the corresponding share class's number
      in the third row under the heading entitled "Expenses Paid During Period"
      to estimate the expenses you paid on your account during this period.

 During Period*
--------------------------------------------------------------------------------------


* Expenses are equal to the Fund's annualized expense ratio plus the expense
  ratios of the underlying funds. These combined totals were 1.32%, 2.22%,
  2.22%, and 0.82% for Class A, Class B, Class C, and Class Y shares,
  respectively. These combined ratios were multiplied by the average account
  value over the period, and then multiplied by 184/365 (to reflect the
  one-half year period) to calculate the Expenses Paid During Period in the
  table above.

Hypothetical Example for Comparison Purposes

The table below provides information about hypothetical account values and
hypothetical expenses based on the Fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not the Fund's actual
return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.


You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
funds.

Please note that the expenses shown in the tables are meant to highlight your
ongoing costs only and do not reflect any transaction costs, such as sales
charges (loads) or redemption fees that are charged at the time of the
transaction. Therefore, the table below is useful in comparing ongoing costs
only and will not help you determine the relative total costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Notes to Financial Statements | 8/31/11

1. Organization and Significant Accounting Policies

Pioneer Global Equity Fund, formerly Pioneer Global Select Equity Fund (the
Fund), is one of four portfolios comprising Pioneer Series Trust V, a Delaware
statutory trust. The Fund is registered under the Investment Company Act of
1940 as a diversified, open-end management investment company. The Fund
commenced operations on December 15, 2005. The Fund's investment objective is
to seek long-term capital growth.

The Fund offers four classes of shares designated as Class A, Class B, Class C
and Class Y shares. Class Y shares were first publicly offered on December 31,
2008. Effective as of the close of business on December 31, 2009, Class B
shares are no longer offered to new or existing shareholders, except that
dividends and/or capital gain distributions may continue to be reinvested in
Class B shares, and shareholders may exchange their Class B shares for Class B
shares of other Pioneer funds, as permitted by existing exchange privileges.
Each class of shares represents an interest in the same portfolio of
investments of the Fund and has identical rights (based on relative net asset
values) to assets and liquidation proceeds. Share classes can bear different
rates of class-specific fees and expenses such as transfer agent and
distribution fees. Differences in class-specific fees and expenses will result
in differences in net investment income and, therefore, the payment of
different dividends from net investment income earned by each class. The
Amended and Restated Declaration of Trust of the Fund gives the Board the
flexibility to specify either per-share voting or dollar-weighted voting when
submitting matters for shareholder approval. Under per-share voting, each share
of a class of the Fund is entitled to one vote. Under dollar-weighted voting, a
shareholder's voting power is determined not by the number of shares owned, but
by the dollar value of the shares on the record date. Each share class has
exclusive voting rights with respect to matters affecting only that class,
including with respect to the distribution plan for that class. There is no
distribution plan for Class Y shares. Class B shares convert to Class A shares
approximately eight years after the date of purchase.

Investing in foreign and/or emerging markets securities involves risks relating
to interest rates, currency exchange rates and economic and political
conditions. At times, the Fund's investments may represent industries or
industry sectors that are interrelated or have common risks, making the Fund

34     Pioneer Global Equity Fund | Annual Report | 8/31/11


The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the
Fund to, among other things, make estimates and assumptions that affect the
reported amounts of assets and liabilities, the disclosure of contingent assets
and liabilities at the date of the financial statements, and the reported
amounts of income, expenses and gain or loss on investments during the
reporting period. Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements, which are consistent with
those policies generally accepted in the investment company industry:


A. Security Valuation

   Security transactions are recorded as of trade date. The net asset value of
   the Fund is computed once daily, on each day the New York Stock Exchange
   (NYSE) is open, as of the close of regular trading on the NYSE. In computing
   the net asset value, securities that have traded on an exchange are valued
   using the last sale price on the principal exchange where they are traded.
   Securities that have not traded on the date of valuation, or securities for
   which sale prices are not available, generally are valued using the mean
   between the last bid and asked prices. Securities for which market prices
   and/or quotations are not readily available or are considered to be
   unreliable are valued using fair value methods pursuant to procedures adopted
   by the Board of Trustees.

   The Fund invests primarily in securities of non-U.S. issuers. The principal
   exchanges and markets for such securities have closing times prior to the
   close of the NYSE. However, the value of these securities may be influenced
   by changes in global markets occurring after the closing times of the local
   exchanges and markets up to the time the Fund determines its net asset value.
   Consequently, the Board of Trustees of the Fund has determined that daily
   adjustments to the valuation of securities of non-U.S. issuers by an
   independent pricing service that supplies an appropriate fair value factor is
   appropriate for the Fund.

   The Fund may use fair value methods if it is determined that a significant
   event has occurred after the close of the exchange or market on which the
   security trades and prior to the determination of the Fund's net asset value.
   Thus, the valuation of the Fund's securities may differ from exchange prices.

   At August 31, 2011, one security, representing 0.1% of total net assets was
   valued using fair value methods (other than securities that were valued using
   prices supplied by independent pricing services). Inputs used when applying
   fair value methods to value a security may include credit ratings, the
   financial condition of the company, current market conditions and comparable
   securities.


                     Pioneer Global Equity Fund | Annual Report | 8/31/11     35


   Short-term fixed income securities with remaining maturities of sixty days or
   less generally are valued at amortized cost. Money market mutual funds are
   valued at net asset value.

   Dividend income is recorded on the ex-dividend date, except that certain
   dividends from foreign securities where the ex-dividend date may have passed
   are recorded as soon as the Fund becomes aware of the ex-dividend data in the
   exercise of reasonable diligence. Interest income, including interest on
   income bearing cash accounts, is recorded on the accrual basis. Dividend and
   interest income are reported net of unrecoverable foreign taxes withheld at
   the applicable country rates.

   Gains and losses on sales of investments are calculated on the identified
   cost method for both financial reporting and federal income tax purposes.


B. Federal Income Taxes

   It is the Fund's policy to comply with the requirements of the Internal
   Revenue Code applicable to regulated investment companies and to distribute
   all of its taxable income and net realized capital gains, if any, to its
   shareowners. Therefore, no federal income tax provision is required. Tax
   years for the prior three fiscal years remain subject to examination by tax
   authorities.

   The amounts and characterizations of distributions to shareowners for
   financial reporting purposes are determined in accordance with federal income
   tax rules. Therefore, the sources of the Fund's distributions may be shown in
   the accompanying financial statements as from or in excess of net investment
   income or as from net realized gain on investment transactions, or as from
   paid-in capital, depending on the type of book/tax differences that may
   exist.

   Under the recently enacted Regulated Investment Company Modernization Act of
   2010, the Fund will be permitted to carry forward capital losses incurred in
   taxable years beginning after December 22, 2010 for an unlimited period.
   However, any losses incurred during those future years will be required to be
   utilized prior to the losses incurred in pre-enactment tax years. As a result
   of this ordering rule, pre-enactment capital loss carryforwards may be more
   likely to expire unused. Additionally, post-enactment capital losses that are
   carried forward will retain their character as either short-term or long-term
   capital losses rather than being considered all short-term as under previous
   law.

   At August 31, 2011, the Fund reclassified $97,186 to decrease undistributed
   net investment income and $97,186 to decrease accumulated net realized loss
   on investments and foreign currency transactions to reflect permanent
   book/tax differences. The reclassification has no impact on the net asset
   value of the Fund and is designed to present the Fund's capital accounts on a
   tax basis.


36     Pioneer Global Equity Fund | Annual Report | 8/31/11


   At August 31, 2011, the Fund had a net capital loss carryforward of
   $54,042,337, which will expire in 2016 if not utilized.

   The tax character of distributions paid during the years ended August 31,
   2011 and August 31, 2010 were as follows:



   ---------------------------------------------------------------
                                               2011          2010
   ---------------------------------------------------------------
                                                   
   Distributions paid from:
   Ordinary income                       $1,127,166      $575,840
   ---------------------------------------------------------------
      Total                              $1,127,166      $575,840
   ===============================================================



   The following shows the components of distributable earnings on a federal
   income tax basis at August 31, 2011:



   ---------------------------------------------------------------
                                                             2011
   ---------------------------------------------------------------
                                                 
   Distributable earnings:
   Undistributed ordinary income                    $   1,202,656
   Capital loss carryforward                          (54,042,337)
   Net unrealized loss                                 (4,475,635)
   ---------------------------------------------------------------
      Total                                         $ (57,315,316)
   ===============================================================


   The difference between book-basis and tax-basis unrealized depreciation is
   attributable to the tax deferral of losses on wash sales and the mark-to-
   market of foreign currency contracts.


C. Fund Shares

   The Fund records sales and repurchases of its shares as of trade date.
   Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund
   and a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit),
   earned $7,230 in underwriting commissions on the sale of Class A shares
   during the year ended August 31, 2011.


D. Foreign Currency Translation

   The books and records of the Fund are maintained in U.S. dollars. Amounts
   denominated in foreign currencies are translated into U.S. dollars using
   current exchange rates. Net realized gains and losses on foreign currency
   transactions, if any, represent, among other things, the net realized gains
   and losses on foreign currency contracts, disposition of foreign currencies
   and the difference between the amount of income accrued and the U.S. dollars
   actually received. Further, the effects of changes in foreign currency
   exchange rates on investments are not segregated in the statement of
   operations from the effects of changes in market price of those securities
   but are included with the net realized and unrealized gain or loss on
   investments.


                     Pioneer Global Equity Fund | Annual Report | 8/31/11     37


E. Forward Foreign Currency Contracts

   The Fund may enter into forward foreign currency contracts (contracts) for
   the purchase or sale of a specific foreign currency at a fixed price on a
   future date. All contracts are marked to market daily at the applicable
   exchange rates, and any resulting unrealized gains or losses are recorded in
   the Fund's financial statements. The Fund records realized gains and losses
   at the time a portfolio hedge is offset by entry into a closing transaction
   or extinguished by delivery of the currency. Risks may arise upon entering
   into these contracts from the potential inability of counterparties to meet
   the terms of the contract and from unanticipated movements in the value of
   foreign currencies relative to the U.S. dollar (see Note 6).


F. Class Allocations

   Income, common expenses and realized and unrealized gains and losses are
   calculated at the Fund level and allocated daily to each class of shares
   based on its respective percentage of adjusted net assets at the beginning of
   the day.

   Distribution fees are calculated based on the average daily net asset value
   attributable to Class A, Class B and Class C shares of the Fund, respectively
   (see Note 4). Class Y shares do not pay distribution fees. All expenses and
   fees paid to the transfer agent, Pioneer Investment Management Shareholder
   Services, Inc. (PIMSS), for its services, are allocated among the classes of
   shares based on the number of accounts in each class and the ratable
   allocation of related out-of-pocket expenses (see Note 3).

   Distributions to shareowners are recorded as of the ex-dividend date.
   Distributions paid by the Fund with respect to each class of shares are
   calculated in the same manner and at the same time, except that net
   investment income dividends to Class A, Class B, Class C and Class Y shares
   can reflect different transfer agent and distribution expense rates.


G. Securities Lending

   The Fund lends securities in its portfolio to certain broker-dealers or other
   institutional investors. When entering into a securities loan transaction,
   the Fund typically receives cash collateral from the borrower equal to at
   least the value of the securities loaned, which is invested in temporary
   investments. Credit Suisse AG, New York Branch, as the Fund's securities
   lending agent, manages the Fund's securities lending collateral. The income
   earned on the investment of collateral is shared with the borrower and the
   lending agent in payment of any rebate due to the borrower with respect to
   the securities loan, and in compensation for the lending agent's services to
   the Fund. The Fund also continues to receive payments in lieu of dividends or
   interest on the securities loaned. Gain or loss on the value of the loaned
   securities that may occur during the term of the loan will be for the account
   of the Fund. The amount of the collateral is required to be adjusted daily to
   reflect any


38     Pioneer Global Equity Fund | Annual Report | 8/31/11


   price fluctuation in the value of the loaned securities. If the required
   market value of the collateral is less than the value of the loaned
   securities, the borrower is required to deliver additional collateral for the
   account of the Fund prior to the close of business on that day. The Fund has
   the right, under the lending agreement, to terminate the loan and recover the
   securities from the borrower with prior notice. The Fund is required to
   return the cash collateral to the borrower and could suffer a loss if the
   value of the collateral, as invested, has declined.


2. Management Agreement

Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary
of UniCredit, manages the Fund's portfolio. Management fees are calculated
daily at the annual rate of 0.75% of the Fund's average daily net assets up to
$500 million, 0.70% of the next $500 million and 0.65% on assets over $1
billion. For the year ended August 31, 2011, the effective management fee
(excluding waivers and/or assumption of expenses) was equivalent to 0.75% of
the Fund's average daily net assets.

PIM has contractually agreed to limit ordinary operating expenses of the Fund
to the extent required to reduce the Fund's expenses to 1.30%, 2.20%, 2.20%,
and 0.80% of the average daily net assets attributable to Class A, Class B,
Class C and Class Y shares, respectively. Expenses waived and reimbursed during
the year ended August 31, 2011 are reflected on the Statement of Operations.
These expense limitations are in effect through January 1, 2012 for each class
of shares. There can be no assurance that PIM will extend the expense
limitation agreement for a class of shares beyond the date referred to above.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund as administrative reimbursements. Included in
"Due to affiliates" reflected on the Statement of Assets and Liabilities is
$2,771 in management fees, administrative costs and certain other
reimbursements payable to PIM at August 31, 2011.


3. Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially
all transfer agent and shareowner services to the Fund at negotiated rates.

In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by
PIMSS related to shareholder communications activities such as proxy and
statement mailings, outgoing phone calls and omnibus relationship contracts.


                     Pioneer Global Equity Fund | Annual Report | 8/31/11     39

Class A                                                                 $ 84,088
Class B                                                                   12,313
Class C                                                                   13,891
Class Y                                                                    3,231
--------------------------------------------------------------------------------
   Total:                                                               $113,523
================================================================================



Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $37,330 in transfer agent fees and out-of-pocket reimbursements
payable to PIMSS at August 31, 2011.


4. Distribution Plan

The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the
Investment Company Act of 1940 with respect to its Class A, Class B and Class C
shares. Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net
assets attributable to Class A shares as compensation for personal services
and/or account maintenance services or distribution services with regard to
Class A shares. Pursuant to the Plan, the Fund also pays PFD 1.00% of the
average daily net assets attributable to Class B and Class C shares. The fee
for Class B and Class C shares consists of a 0.25% service fee and a 0.75%
distribution fee paid as compensation for personal services and/or account
maintenance services or distribution services with regard to Class B and Class
C shares. Included in "Due to affiliates" reflected on the Statement of Assets
and Liabilities is $700 in distribution fees payable to PFD at August 31, 2011.


In addition, redemptions of each class of shares (except Class Y shares) may be
subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be
imposed on redemptions of certain net asset value purchases of Class A shares
within 12 months of purchase. Class B shares that are redeemed within five
years of purchase are subject to a CDSC at declining rates beginning at 4.00%,
based on the lower of cost or market value of shares being redeemed.
Redemptions of Class C shares within one year of purchase are subject to a CDSC
of 1.00%, based on the lower of cost or market value of shares being redeemed.
Shares purchased as part of an exchange remain subject to any CDSC that applied
to the original purchase of those shares. There is no CDSC for Class Y shares.
Proceeds from the CDSCs are paid to PFD. For the year ended August 31, 2011,
CDSCs in the amount of $5,078 were paid to PFD.


40     Pioneer Global Equity Fund | Annual Report | 8/31/11


5. Expense Offsets Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS, which
may result in a reduction in the Fund's total expenses due to interest earned
on cash held by PIMSS. For the year ended August 31, 2011, the Fund's expenses
were not reduced under such arrangements.


6. Forward Foreign Currency Contracts

At August 31, 2011, the Fund had entered into various forward foreign currency
contracts that obligate the Fund to deliver or take delivery of currencies at
specified future maturity dates. Alternatively, prior to the settlement date of
a forward foreign currency contract, the Fund may close out such contract by
entering into an offsetting contract. The Fund's gross forward currency
settlement contracts receivable and payable were $1,954,526 and $1,955,000,
respectively, resulting in a net payable of $474. The average value of
contracts open during the year ended August 31, 2011 was $16,655,204. Open
portfolio hedges at August 31, 2011 were as follows:

Report of Independent Registered Public Accounting Firm

To the Trustees of Pioneer Series Trust V and
Shareholders of Pioneer Global Equity Fund:
--------------------------------------------------------------------------------
We have audited the accompanying statement of assets and liabilities of Pioneer
Global Equity Fund (the Fund), (one of the portfolios constituting Pioneer
Series Trust V), including the schedule of investments, as of August 31, 2011,
and the related statement of operations for the year then ended, the statements
of changes in net assets for each of the two years in the period then ended,
and the financial highlights for each of the periods indicated therein. These
financial statements and financial highlights are the responsibility of the
Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. We were not engaged to perform an audit of the Fund's internal
control over financial reporting. Our audits included consideration of internal
control over financial reporting as a basis for designing audit procedures that
are appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Fund's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights, assessing the accounting
principles used and significant estimates made by management, and evaluating
the overall financial statement presentation. Our procedures included
confirmation of securities owned as of August 31, 2011, by correspondence with
the custodian and brokers or by other appropriate auditing procedures where
replies from brokers were not received. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer Global Equity Fund at August 31, 2011, the results of its operations
for the year then ended, the changes in its net assets for each of the two
years in the period then ended, and the financial highlights for each of the
periods indicated therein, in conformity with U.S. generally accepted
accounting principles.

              Pioneer High Income Municipal Fund | Annual Report | 8/31/11     1


President's Letter

Dear Shareowner,

The U.S. economy went through a soft patch in the first half of 2011, and the
second half of the year, so far, has been highlighted by the U.S. government's
battle over the debt ceiling and Standard & Poor's downgrade of the U.S.
Treasury's credit rating from the top rating of "AAA" for the first time in
history. The markets reacted quite negatively to the credit downgrade, and there
is concern about the strength of the global economy going forward.

Pioneer is cautiously optimistic that the U.S. economy will see moderate
economic growth over the balance of 2011, though at a slower pace than we had
expected earlier this year. While housing and employment remain weak, the
private sector shows signs of slow but steady improvement, led by higher capital
investment, solid exports, and improved consumption. At the same time, the risks
to growth remain substantial, including high unemployment, continued delays in
the housing sector's recovery, and the fiscal drag of U.S. federal and state
budget cuts.

The difficult recovery process has been accompanied by wide market swings. While
this is a challenging environment, our investment professionals continue to
focus on finding good opportunities to invest in both equity and bond markets
using the same disciplined approach Pioneer has used since 1928. Our approach is
to identify undervalued individual securities with the greatest potential for
success, carefully weighing risk against reward. Our teams of investment
professionals continually monitor and analyze the relative valuations of
different sectors and securities globally to help build portfolios that we
believe can help you achieve your investment goals.

At Pioneer, we have long advocated the benefits of staying diversified and
investing for the long term. The strategy has generally performed well for many
investors. Our advice, as always, is to work closely with a trusted financial
advisor to discuss your goals and work together to develop an investment
strategy that meets your individual needs. There is no single best strategy that
works for every investor.

Portfolio Management Discussion | 8/31/11

Despite facing down a variety of domestic and global headwinds during the 12
months ended August 31, 2011, municipal bonds finished the period with positive
results. In the following interview, Timothy Pynchon, vice president at Pioneer
and lead portfolio manager of Pioneer High Income Municipal Fund, discusses the
factors that affected the municipal bond market and the Fund's performance over
the 12-month period ended August 31, 2011. Mr. Pynchon is responsible for the
day-to-day management of the Fund and is supported by David Eurkus, vice
president of Pioneer.

Q     How did the Fund perform during the 12-month period ended August 31, 2011?

A     Pioneer High Income Municipal Fund Class A shares returned 1.83% at net
      asset value during the 12 months ended August 31, 2011, while the Fund's
      benchmark, the Barclays Capital High Yield Municipal Bond Index (the
      Barclays Index), returned 3.45%. Over the same period the average return
      of the 126 mutual funds in Lipper's High Yield Municipal Debt Funds
      category was 0.86%. As of August 31, 2011, the Fund's Class A shares
      provided a 30-day SEC yield of 6.89%. As of August 31, 2011, 21.66% of the
      Fund's investments were subject to the federal Alternative Minimum Tax
      (AMT), and the Fund held investments in 207 bond issues from 30 states.

Q     What was the investment environment like for high-yield municipal bonds
      during the 12 months ended August 31, 2011?

A     The period started out on a positive note, with high-yield municipal bonds
      continuing a favorable performance trend that had begun in 2010. In
      November 2010, however, well-publicized remarks of one financial analyst
      warning of the possibility of widespread bankruptcies by municipalities
      cast a shadow over the municipal market, including high-yield issues. We
      did not share that view at the time and continue to believe that while
      budget shortfalls exist in many states and municipalities, the chance of
      widespread defaults and bankruptcies remains very small.

      The municipal bond market felt the effect of those remarks for several
      months, producing tepid results into mid-April 2011 when investors began
      to recognize the value that municipal bonds offered. At first, investors
      favored investment-grade bonds when they came back to the market, but
      gradually moved into high-yield issues. In July and August 2011, national
      and global concerns crept into the municipal market. For example,
      uncertainty about raising the U.S. debt ceiling as well as the potential
      for an

4     Pioneer High Income Municipal Fund | Annual Report | 8/31/11


      economic slowdown in Europe and its effect on the U.S. economy and
      corporate profitability weighed on investors. As a result, the municipal
      bond market closed the 12-month period ended August 31, 2011, in a
      slightly weaker, though positive, state.

Q     What were your investment strategies for the Fund during the 12 months
      ended August 31, 2011, and how did they affect the Fund's performance?

A     Throughout the period, we invested the Fund exclusively in revenue bonds,
      which rely on revenues from specific funding sources. We avoided general
      obligation bonds, which are financed by municipal tax revenues and are
      more directly exposed to the general financial problems of state and local
      governments. Investments in health care, particularly continuing care
      retirement communities, and airlines and airports accounted for the
      largest positions in the Fund's portfolio. As of August 31, 2011,
      approximately 40% of the Fund's assets were invested in health care; and
      approximately 24% of the Fund's assets were invested in airline and
      airport bonds. Education bonds accounted for 7.7% of assets, with the
      focus primarily on charter schools in areas with underperforming public
      school systems. As a way to meet redemptions during the weakness in the
      municipal market, we took advantage of the strong valuations of corporate
      revenue bonds and trimmed the Fund's exposure to the sector. We
      substantially reduced the Fund's investments in tobacco bonds because our
      fundamental view changed. Concerns about disputed payments within the
      national settlement agreement and a decline in consumption, which is
      likely to have a negative impact on the bonds over the long term, drove
      the changes. On August 31, 2011, approximately 2.0% of the Fund's assets
      were invested in tobacco bonds, down from roughly 11% of assets on
      February 28, 2011.

      The Fund's focus on revenue bonds, as opposed to general obligation bonds,
      benefited performance during the 12-month period. The Fund's position in
      tobacco bonds, which are not part of the benchmark Barclays Index,
      dampened results.

Q     What is your investment outlook?

A     We are positive in our outlook for the high-yield municipal bond market.
      During 2011 the rate of new issuance has been robust, at approximately 45%
      of 2010 levels, and the fundamentals of the underlying assets are strong.
      We believe that some of the turmoil in other asset classes, including
      equities and other kinds of bonds, should also be positive for municipals,
      as municipal bonds appear to be relatively stable and are attractive on an
      absolute and a relative basis due to their comparatively high current
      yields. Despite our constructive outlook for the high-yield municipal bond
      market, we cannot ignore the macroeconomic issues currently in play on a
      global scale. We do not believe there will be a double-dip recession in
      the United States. However, we expect economic growth to be slower than
      originally

              Pioneer High Income Municipal Fund | Annual Report | 8/31/11     5


      thought; and depending on investors' appetite for risk, that could have a
      negative impact on high-yield municipal bonds.

      As we manage the Fund during these uncertain economic times, our
      investment discipline will continue to be based on independent fundamental
      analysis. Before a security is added to the portfolio, we will maintain
      our practice of analyzing both the credit-worthiness of the issuer and the
      reliability and sustainability of the security's revenue stream. We
      believe there is value in the high-yield municipal bond market, as the
      tax-advantaged yields of municipal securities continue to compare
      favorably with yields provided by taxable bonds.

Please refer to the Schedule of Investments on pages 14-25 for a full listing of
Fund securities.

Investments in high-yield or lower-rated securities are subject to
greater-than-average risk. The Fund may invest in securities of issuers that are
in default or that are in bankruptcy.

A portion of the Fund's income may be subject to state, federal, and/or
alternative minimum tax. Capital gains, if any, are subject to a capital gains
tax. The Fund is not diversified, which means that it can invest a higher
percentage of its assets in any one issuer than a diversified fund. Being
non-diversified may magnify the Fund's losses from adverse events affecting a
particular issuer. By investing primarily in municipal securities, the Fund is
more susceptible to adverse economic, political or regulatory developments than
is a fund that invests more broadly.

When interest rates rise, the prices of fixed-income securities in the Fund will
generally fall. Conversely, when interest rates fall, the prices of fixed-income
securities in the Fund will generally rise. Investments in the Fund are subject
to possible loss due to the financial failure of issuers of underlying
securities and their inability to meet their debt obligations. At times, the
Fund's investments may represent industries or industry sectors that are
interrelated or have common risks, making it more susceptible to any economic,
political, or regulatory developments or other risks affecting those industries
and sectors.

These risks may increase share price volatility.

Past performance is not a guarantee of future results, and there is no guarantee
that market forecasts discussed will be realized.

Any information in this shareholder report regarding market or economic trends
or the factors influencing the Fund's historical or future performance are
statements of opinion as of the date of this report. These opinions should not
be relied upon for any other purposes.

the high-yield municipal bond market. Index returns are calculated monthly,
assume reinvestment of dividends and, unlike Fund returns, do not reflect any
fees, expenses or sales charges. It is not possible to invest directly in an
index.

The index defined here pertains to the "Value of $10,000 Investment" and "Value
of $5 Million Investment" charts shown on pages 10-12.

Call 1-800-225-6292 or visit us.pioneerinvestments.com for the most recent
month-end performance results. Current performance may be lower or higher than
the performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

NAV results represent the percent change in net asset value per share. Returns
would have been lower had sales charges been reflected. POP returns reflect
deduction of maximum 4.50% sales charge. All results are historical and assume
the reinvestment of dividends and capital gains. Other share classes are
available for which performance and expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers may
not be in effect for all funds. Certain fee waivers are contractual through a
specified period. Otherwise, fee waivers can be rescinded at any time. See the
prospectus and financial statements for more information.

The net expense ratio reflects contractual expense limitations currently in
effect through 1/1/12 for Class A shares. There can be no assurance that Pioneer
will extend the expense limitations beyond such time. Please see the prospectus
and financial statements for more information.

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Fund distributions or the redemption of Fund
shares.

Comparing Ongoing Fund Expenses

As a shareowner in the Fund, you incur two types of costs:

(1)   ongoing costs, including management fees, distribution and/or service
      (12b-1) fees, and other Fund expenses; and

(2)   transaction costs, including sales charges (loads) on purchase payments.

This example is intended to help you understand your ongoing expenses (in
dollars) of investing in the Fund and to compare these costs with the ongoing
costs of investing in other mutual funds. The example is based on an investment
of $1,000 at the beginning of the Fund's latest six-month period and held
throughout the six months.

Using the Tables
--------------------------------------------------------------------------------
Actual Expenses

The first table below provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period as
follows:

1.    Divide your account value by $1,000
      Example: an $8,600 account value [divided by] $1,000 = 8.6

2.    Multiply the result in (1) above by the corresponding share class's number
      in the third row under the heading entitled "Expenses Paid During Period"
      to estimate the expenses you paid on your account during this period.

During Period*
--------------------------------------------------------------------------------


*     Expenses are equal to the Fund's annualized expense ratio of 0.88%, 1.63%
      and 0.67% for Class A, Class C and Class Y shares, respectively,
      multiplied by the average account value over the period, multiplied by
      184/365 (to reflect the one-half year period).

Hypothetical Example for Comparison Purposes

The table below provides information about hypothetical account values and
hypothetical expenses based on the Fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not the Fund's actual
return. The hypothetical account values and expenses may not be used to estimate
the actual ending account balance or expenses you paid for the period.

You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the tables are meant to highlight your
ongoing costs only and do not reflect any transaction costs, such as sales
charges (loads) that are charged at the time of the transaction. Therefore, the
table below is useful in comparing ongoing costs only and will not help you
determine the relative total costs of owning different funds. In addition, if
these transaction costs were included, your costs would have been higher.

Notes to Financial Statements | 8/31/11

1.    Organization and Significant Accounting Policies

Pioneer High Income Municipal Fund (the Fund) is one of four portfolios
comprising Pioneer Series Trust V, a Delaware statutory trust. The Fund is
registered under the Investment Company Act of 1940 as an open-end management
investment company. The Fund is non-diversified. The Fund commenced operations
on October 17, 2006. The investment objective of the Fund is to maximize total
return through a combination of income that is exempt from regular federal
income tax and capital appreciation.

The Fund offers three classes of shares designated as Class A, Class C and Class
Y shares. Each class of shares represents an interest in the same portfolio of
investments of the Fund and has identical rights (based on relative net asset
values) to assets and liquidation proceeds. Share classes can bear different
rates of class-specific fees and expenses such as transfer agent and
distribution fees. Differences in class-specific fees and expenses will result
in differences in net investment income and, therefore, the payment of different
dividends from net investment income earned by each class. The Amended and
Restated Declaration of Trust of the Fund gives the Board the flexibility to
specify either per share voting or dollar-weighted voting when submitting
matters for shareholder approval. Under per share voting, each share of a class
of the Fund is entitled to one vote. Under dollar-weighted voting, a
shareholder's voting power is determined not by the number of shares owned, but
by the dollar value of the shares on the record date. Each share class has
exclusive voting rights with respect to matters affecting only that class,
including with respect to the distribution plan for that class. There is no
distribution plan for Class Y shares.

At times, the Fund's investments may represent industries or industry sectors
that are interrelated or have common risks, making the Fund more susceptible to
any economic, political, or regulatory developments or other risks affecting
those industries and sectors. The Fund's prospectus contains unaudited
information regarding the Fund's principal risks. Please refer to that document
when considering the Fund's principal risks.

The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the Fund
to, among other things, make estimates and assumptions that affect the reported
amounts of assets and liabilities, the disclosure of contingent assets and
liabilities at the date of the financial statements, and the reported amounts of
income, expenses, and gain or loss on investments during the reporting period.
Actual results could differ from those estimates.

             Pioneer High Income Municipal Fund | Annual Report | 8/31/11     33


The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements which are consistent with
those policies generally accepted in the investment company industry:

A.    Security Valuation

      Security transactions are recorded as of trade date. The net asset value
      of the Fund is computed once daily, on each day the New York Stock
      Exchange (NYSE) is open, as of the close of regular trading on the NYSE.
      Fixed income securities with remaining maturity of more than sixty days
      are valued at prices supplied by independent pricing services, which
      consider such factors as market prices, market events, quotations from one
      or more brokers, Treasury spreads, yields, maturities and ratings.
      Valuations may be supplemented by dealers and other sources, as required.

      Securities for which independent pricing services are unable to supply
      prices or for which market prices and/or quotations are not readily
      available or are considered to be unreliable are valued using fair value
      methods pursuant to procedures adopted by the Board of Trustees.

      The Fund may use fair value methods if it is determined that a significant
      event has occurred after the close of the exchange or market on which the
      security trades and prior to the determination of the Fund's net asset
      value. Thus, the valuation of the Fund's securities may differ from
      exchange prices.

      At August 31, 2011, there were no securities that were valued using fair
      value methods (other than securities valued using prices supplied by
      independent pricing services). Inputs used when applying fair value
      methods to value a security may include credit ratings, the financial
      condition of the company, current market conditions and comparable
      securities. Short-term fixed income securities with remaining maturities
      of sixty days or less generally are valued at amortized cost. Money market
      mutual funds are valued at net asset value.

      Discount and premium on debt securities are accreted or amortized,
      respectively, daily into interest income on a yield-to-maturity basis with
      a corresponding increase or decrease in the cost basis of the security.
      Interest income is recorded on the accrual basis.

      Gains and losses on sales of investments are calculated on the identified
      cost method for both financial reporting and federal income tax purposes.

B.    Federal Income Taxes

      It is the Fund's policy to comply with the requirements of the Internal
      Revenue Code applicable to regulated investment companies and to
      distribute all of its taxable income, exempt interest income, and net
      realized capital gains, if any, to its shareowners. Therefore, no federal
      income tax provision

34     Pioneer High Income Municipal Fund | Annual Report | 8/31/11


      is required. Tax years for the prior three fiscal years remain subject to
      examination by tax authorities.

      The amounts and characterizations of distributions to shareowners for
      financial reporting purposes are determined in accordance with federal
      income tax rules. Therefore, the sources of the Fund's distributions may
      be shown in the accompanying financial statements as from or in excess of
      net investment income or as from net realized gain on investment
      transactions, or as from paid-in capital, depending on the type of
      book/tax differences that may exist.

      At August 31, 2011, the Fund had a net capital loss carryforward of
      $8,649,148, of which the following amounts will expire in 2017 and 2018 if
      not utilized: $2,640,380 in 2017 and $6,008,768 in 2018.

      The Fund has elected to defer approximately $13,467,896 of capital losses
      recognized between November 1, 2010 and August 31, 2011 to its fiscal year
      ending August 31, 2012.

      At August 31, 2011, the Fund reclassified $54,524 to decrease
      undistributed net investment income and $54,524 to decrease accumulated
      net realized loss, to reflect permanent book/tax differences. The
      reclassification has no impact on the net assets of the Fund and presents
      the Fund's capital accounts on a tax basis.

      Under the recently enacted Regulated Investment Company Modernization Act
      of 2010, the Fund will be permitted to carry forward capital losses
      incurred in taxable years beginning after December 22, 2010 for an
      unlimited period. However, any losses incurred during those future years
      will be required to be utilized prior to the losses incurred in
      pre-enactment tax years. As a result of this ordering rule, pre-enactment
      capital loss carryforwards may be more likely to expire unused.
      Additionally, post-enactment capital losses that are carried forward will
      retain their character as either short-term or long-term capital losses
      rather than being considered all short-term as under previous law.

      The tax character of distributions paid during the years ended August 31,
      2011 and August 31, 2010 was as follows:



--------------------------------------------------------------------------------
                                                             2011           2010
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
                                                               
Distributable earnings:
Undistributed tax exempt income                                   $     714,703
Capital loss carryforward                                            (8,649,148)
Post-October loss deferred                                          (13,467,896)
Dividend payable                                                     (1,391,335)
Net unrealized gain                                                   4,457,447
--------------------------------------------------------------------------------
   Total                                                          $ (18,336,229)
================================================================================


      The difference between book-basis and tax-basis unrealized appreciation is
      attributable to the tax deferral of losses on wash sales, the tax
      treatment of premium and amortization and tax-basis adjustments on
      partnerships.

      The Fund records sales and repurchases of its shares as of trade date.
      Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the
      Fund and a wholly owned indirect subsidiary of UniCredit S.p.A.
      (UniCredit), earned $268,442 in underwriting commissions on the sale of
      Class A shares during the year ended August 31, 2011.

D.    Class Allocations

      Income, common expenses and realized and unrealized gains and losses are
      calculated at the Fund level and allocated daily to each class of shares
      based on its respective percentage of adjusted net assets at the beginning
      of the day.

      Distribution fees are calculated based on the average daily net asset
      value attributable to Class A and Class C shares of the Fund, respectively
      (see Note 4). Class Y shares do not pay distribution fees. All expenses
      and fees paid to the transfer agent, Pioneer Investment Management
      Shareholder Services, Inc. (PIMSS), for its services are allocated among
      the classes of shares based on the number of accounts in each class and
      the ratable allocation of related out-of-pocket expenses (see Note 3).

      The Fund declares, as daily dividends, substantially all of its net
      investment income. All dividends are paid on a monthly basis. Short-term
      capital gain distributions, if any, may be declared with the daily
      dividends. Distributions to shareowners are recorded as of the ex-dividend
      date. Distributions paid by the Fund with respect to each class of shares
      are calculated in the same manner and at the same time, except that net
      investment income dividends to Class A, Class C, and Class Y shares can
      reflect different transfer agent and distribution expense rates.

2.    Management Agreement

Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary of
UniCredit, manages the Fund's portfolio. Management fees are calculated daily at
the annual rate of 0.50% of the Fund's average daily net assets up to $500
million; 0.475% on the next $500 million; and 0.45% on assets over $1 billion.
For the year ended August 31, 2011, the effective management fee (excluding
waivers and/or assumption of expenses) was equivalent to 0.49% of the Fund's
average daily net assets.

PIM has contractually agreed to limit ordinary operating expenses (excluding
taxes, commissions, interest and extraordinary expenses) of the Fund to the
extent required to reduce the Fund's expenses to 0.90% and 1.80% of the average
daily net assets attributable to Class A shares and Class C shares,
respectively. These expense limitations are in effect through January 1, 2012
for Class A and Class C shares. There can be no assurance that PIM will extend
the expense limitation agreement for a class of shares beyond the date referred
to above.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund as administrative reimbursements. Included in
"Due to affiliates" reflected on the Statement of Assets and Liabilities is
$11,621 in management fees, administrative costs and certain other
reimbursements payable to PIM at August 31, 2011.

3.    Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially
all transfer agent and shareowner services to the Fund at negotiated rates.

In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by
PIMSS related to shareholder communications activities such as proxy and
statement mailings, outgoing phone calls and omnibus relationship contracts. For
the year ended August 31, 2011, such out-of-pocket expenses by class of shares
were as follows:

Class A                                                                 $ 91,539

             Pioneer High Income Municipal Fund | Annual Report | 8/31/11     37


4.    Distribution Plan

The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the
Investment Company Act of 1940 with respect to its Class A and Class C shares.
Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net assets
attributable to Class A shares as compensation for personal services and/or
account maintenance services or distribution services with regard to Class A
shares. Pursuant to the Plan, the Fund also pays PFD 1.00% of the average daily
net assets attributable to Class C shares. The fee for Class C shares consists
of a 0.25% service fee and a 0.75% distribution fee paid as compensation for
personal services and/or account maintenance services or distribution services
with regard to Class C shares. Included in "Due to affiliates" reflected on the
Statement of Assets and Liabilities is $9,254 in distribution fees payable to
PFD at August 31, 2011.

In addition, redemptions of each class of shares (except Class Y shares) may be
subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be
imposed on redemptions of certain net asset value purchases of Class A shares
within 12 months of purchase. Redemptions of Class C shares within one year of
purchase are subject to a CDSC of 1.00%, based on the lower of cost or market
value of shares being redeemed. Shares purchased as part of an exchange remain
subject to any CDSC that applied to the original purchase of those shares. There
is no CDSC for Class Y shares. Proceeds from the CDSCs are paid to PFD. For the
year ended August 31, 2011, CDSCs in the amount of $360,114 were paid to PFD.

5.    Expense Offset Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS which
may result in a reduction in the Fund's total expenses due to interest earned on
cash held by PIMSS. For the year ended August 31, 2011, the Fund's expenses were
not reduced under such arrangements.

6.    Line of Credit Facility

The Fund, along with certain other funds in the Pioneer Family of Funds (the
Funds), participates in a $165 million committed, unsecured revolving line of
credit facility. Borrowings are used solely for temporary or emergency purposes.
The Fund may borrow up to the lesser of the amount available under the facility
or the limits set for borrowing by the Fund's prospectus and the 1940 Act.
Interest on borrowings is payable at the higher of the London Interbank Offered
Rate (LIBOR) on the borrowing date plus 1.25% on an annualized basis or the
Federal Funds Rate on the borrowing date plus 1.25% on an annualized basis. The
Funds pay an annual commitment fee for this facility. The commitment fee is
allocated among participating Funds based on an allocation schedule set forth in
the credit agreement.

38     Pioneer High Income Municipal Fund | Annual Report | 8/31/11

outstanding during the period was $2,464,518. The related weighted average

Report of Independent Registered Public Accounting Firm

To the Trustees of Pioneer Series Trust V and
Shareholders of Pioneer High Income Municipal Fund:
--------------------------------------------------------------------------------
We have audited the accompanying statement of assets and liabilities of Pioneer
High Income Municipal Fund (the Fund) (one of the portfolios constituting
Pioneer Series Trust V), including the schedule of investments, as of August 31,
2011, and the related statement of operations for the year then ended, the
statement of changes in net assets for each of the two years in the period then
ended, and the financial highlights for each of the periods indicated therein.
These financial statements and financial highlights are the responsibility of
the Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Fund's internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Fund's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of August 31, 2011, by correspondence with the custodian and
brokers or by other appropriate auditing procedures where replies from brokers
were not received. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer High Income Municipal Fund at August 31, 2011, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each of
the periods indicated therein, in conformity with U.S. generally accepted
accounting principles.

 PIONEER FUNDS
            APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES
                       PROVIDED BY THE INDEPENDENT AUDITOR

                  SECTION I - POLICY PURPOSE AND APPLICABILITY

The Pioneer Funds recognize the importance of maintaining the independence of
their outside auditors. Maintaining independence is a shared responsibility
involving Pioneer Investment Management, Inc ("PIM"), the audit committee and
the independent auditors.

The Funds recognize that a Fund's independent auditors: 1) possess knowledge of
the Funds, 2) are able to incorporate certain services into the scope of the
audit, thereby avoiding redundant work, cost and disruption of Fund personnel
and processes, and 3) have expertise that has value to the Funds. As a result,
there are situations where it is desirable to use the Fund's independent
auditors for services in addition to the annual audit and where the potential
for conflicts of interests are minimal. Consequently, this policy, which is
intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and
procedures to be followed by the Funds when retaining the independent audit firm
to perform audit, audit-related tax and other services under those
circumstances, while also maintaining independence.

Approval of a service in accordance with this policy for a Fund shall also
constitute approval for any other Fund whose pre-approval is required pursuant
to Rule 210.2-01(c)(7)(ii).

In addition to the procedures set forth in this policy, any non-audit services
that may be provided consistently with Rule 210.2-01 may be approved by the
Audit Committee itself and any pre-approval that may be waived in accordance
with Rule 210.2-01(c)(7)(i)(C) is hereby waived.

Selection of a Fund's independent auditors and their compensation shall be
determined by the Audit Committee and shall not be subject to this policy.

  pre-approved service subcategories set forth above must be specifically
  approved by the Audit Committee.

  services by service category, including fees, provided by the Audit firm as
  set forth in the above policy.

Rule 2-01 of Regulation S-X is compatible with maintaining the principal
accountant's independence.

internal controls or in other factors that could significantly affect these
controls subsequent to the date of their evaluation, including any corrective
actions with regard to significant deficiencies and material weaknesses.

There were no significant changes in the
registrant's internal control over financial
reporting that occurred during the second
fiscal quarter of the period covered by this
report that have materially affected, or are
reasonably likely to materially affect, the
registrant's internal control over financial
reporting.

The registrant's principal executive officer and principal financial
officer, however, voluntarily are reporting the following information:

In August of 2006 the registrant's investment adviser
enhanced its internal procedures for reporting performance
information required to be included in prospectuses.
Those enhancements involved additional internal controls
over the appropriateness of performance data
generated for this purpose.  Such enhancements were made
following an internal review which identified
prospectuses relating to certain classes of shares of
a limited number of registrants where, inadvertently,
performance information not reflecting the deduction of
applicable sales charges was included. Those prospectuses
were revised, and the revised prospectuses were distributed to
shareholders.

financial officer of the registrant as required by Rule 30a-2 under the Act
