President's Letter

Dear Shareholder,

Over the past several years, many investors experienced positive returns across
most major asset classes. However, 2015 was a tale of two markets, with
favorable market conditions in the first half of the year, followed by an abrupt
slowdown and increased volatility beginning in August. The global markets were
challenged by significant economic cross-currents in different geographic
regions and industrial sectors. While the U.S. economy gradually improved,
growth slowed in China. Emerging markets struggled following a decline in
commodity prices, especially oil. While lower energy prices are good for the
consumer, there were ripple effects throughout the global economy.

Against this backdrop, the Standard & Poor's 500 Index rose by just 1.4% in
2015, international equity markets were essentially flat, and emerging market
equities fell sharply. Across U.S. fixed-income sectors, U.S. government and
investment-grade corporate bonds were fairly flat for the year, while high-yield
bonds, as measured by the Bank of America Merrill Lynch Master II High Yield
Index, posted a -4.9% total return.

Entering 2016, we see the possibility of a cyclical upswing, against an overall
economic backdrop that remains fragile and points towards structurally lower
growth. As always in a Presidential election year, political rhetoric has the
potential to impact U.S. sectors such as health care in 2016. Economies around
the world in both developed and emerging markets are experiencing deep
structural change. Geopolitical instability on many fronts, the rising risk of
policy mistakes, and market liquidity issues all increase the possibility of
sharp swings in asset values. In this environment, financial markets remain
vulnerable to unusual levels of volatility. While divergences among regions and
industries is an important theme, we are generally optimistic about the outlook
for the U.S. economy, which we expect will see modest growth.

Throughout Pioneer's history, we have believed in the importance of active
management. In periods of market volatility, we believe that the value of active
management is even more compelling. Our experienced and tenured investment teams
focus on identifying value across global markets using proprietary research,
careful risk management, and a long-term perspective. Our ongoing goal is to
produce compelling returns consistent with the stated objectives of our
investment products, and with our shareowners' expectations. We believe our
shareowners can benefit from the experience and tenure of our investment teams
as well as the insights generated from our extensive research process.

2 Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/15


As always, and particularly during times of market uncertainty, we encourage you
to work with your financial advisor to develop an overall investment plan that
addresses both your short- and long-term goals, and to implement such a plan in
a disciplined manner.

We greatly appreciate the trust you have placed in us and look forward to
continuing to serve you in the future.

Sincerely,

/s/ Lisa M. Jones

Portfolio Management Discussion | 11/30/15

During the 12-month period ended November 30, 2015, returns for Pioneer Select
Mid Cap Growth Fund exceeded those of the Fund's benchmark, the Russell Midcap
Growth Index, and the Fund's Lipper and Morningstar peers. In the following
interview, Ken Winston reviews the investment background and details some of the
factors and decisions that drove the Fund's performance during the 12-month
period. Mr. Winston, a vice president and a portfolio manager at Pioneer, is
responsible for the day-to-day management of the Fund, along with Shaji John, a
vice president and a portfolio manager at Pioneer, and Jon Stephenson, a vice
president and a portfolio manager at Pioneer.

Q    How did the Fund perform during the 12-month period ended November 30,
     2015?

A    Pioneer Select Mid Cap Growth Fund's Class A shares returned 3.13% at net
     asset value during the 12-month period ended November 30, 2015, while the
     Fund's benchmark, the Russell Midcap Growth Index (the Russell Index),
     returned 1.82%. During the same 12-month period, the average return of the
     396 mutual funds in Lipper's Mid Cap Growth Funds category was 1.82%, and
     the average return of the 738 mutual funds in Morningstar's Mid Cap Growth
     Funds category was 1.92%.

Q    How would you describe the investment environment for equities during the
     12-month period ended November 30, 2015?

A    After peaking in June 2015, U.S. equity markets became very volatile over
     the balance of the reporting period, despite generally favorable economic
     conditions. Economic growth, overall, was steady, but fell short of the
     accelerated pace hoped for by market participants. Employment trends
     featured healthy job creation late in the period, after months of sluggish
     gains. Oil prices remained low, wreaking severe damage on the energy
     sector, with spillover effects into several industrial businesses.

     With regard to energy, we think the negatives attributable to slumping oil
     and other commodity prices outweighed the benefits, as low energy prices
     appeared not to have stimulated consumer spending, with rising costs for
     health care, rents, and other day-to-day expenses offsetting any savings
     consumers derived from reduced energy outlays. Robust car and truck sales -
     direct beneficiaries of low prices at the gas pump - were a notable bright
     spot in the consumer discretionary sector. Moreover, unusually warm weather
     during the fall hurt sales of winter goods.

     Included among several issues that caused anxiety in the markets during the
     period were the growing likelihood of higher U.S. interest rates and the
     impact of a strong U.S. dollar on exporters. In addition, China's economic

4 Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/15


     growth slackened, eroding global demand for commodities and industrial
     goods. Other emerging markets economies also slowed markedly, with Brazil,
     in particular, suffering recession-like conditions.

Q    What were the main reasons for the Fund's outperformance of its benchmark,
     the Russell Index, during the 12-month period ended November 30, 2015?

A    The Fund's outperformance of the Russell Index stemmed entirely from
     successful stock selection, whereas asset allocation decisions hurt
     relative returns.

     Within the Russell Index, health care, consumer staples and information
     technology were the strongest-performing sectors, while energy, utilities
     and telecommunication services delivered the weakest performance during the
     period. The Fund's strongest selection results relative to the benchmark
     were in consumer discretionary, information technology and health care.

     Meanwhile, the portfolio's overweight stance in the slumping energy sector
     detracted from the Fund's benchmark-relative performance, while an
     overweight of the strong-performing health care sector only partially
     offset the damage done by the energy overweight.

Q    Which stock selections had the greatest positive impact on the Fund's
     benchmark-relative performance during the 12-month period ended November
     30, 2015?

A    In the information technology sector, the Fund's shares of Skyworks
     Solutions made the largest overall contribution to benchmark-relative
     returns during the 12-month period. Skyworks, which designs and
     manufactures semiconductors for mobile devices, continued to gain market
     share over the period. The company has shown particular strength in
     integrating multiple functions (amplification, filtering, switching) onto
     individual chips. Skyworks also has made good progress in broad markets,
     such as automobiles, connected homes and industrial applications. Skyworks'
     chips have met the challenge of being compatible with phones that operate
     on various global standards, thus reducing the need for separate phones in
     different regions. Finally, the so-called "Internet of Things," which is
     the rapid proliferation of connected devices, has the potential to expand
     the company's earnings in coming years.

     In health care, a position in Neurocrine Biosciences was a solid
     contributor to the Fund's relative performance. Neurocrine is a
     biopharmaceutical company that develops treatments for neurological and
     endocrine diseases. One of Neurocrine's lead products, Elagolix, an oral
     drug for endometriosis and uterine fibroids, is expected to launch in 2017,
     based on continued positive trial data. Favorable trial results, too, are
     boosting prospects for

                 Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/15 5


     Neurocrine's second-leading product, Valbenazine. The drug, also expected
     to reach the market in 2017, targets Tardive dyskinesia and Tourette's
     syndrome; treatments for those conditions hold big market potential.

     A position in another biopharmaceutical firm, Alkermes, also aided the
     Fund's relative returns during the period. Alkermes has several drugs on
     the market and in its pipeline that target schizophrenia, addiction and
     depression. The company's shares rose in price as investors came to
     appreciate the potential of the drug ALKS 3831 in treating schizophrenia.
     Alkermes' broad pipeline also includes a promising drug for the treatment
     of multiple sclerosis (M.S.). Both ALKS 3831 and the M.S. drug have
     demonstrated solid clinical data. Also in health care, NPS Pharmaceuticals,
     a long-time portfolio holding, was acquired by Shire during the period at a
     significant premium to its market price, thus contributing to the Fund's
     relative performance. The medications produced by NPS target rare
     gastrointestinal disorders.

     In financial services, the Fund's shares of Nasdaq, an operator of global
     market exchanges and a purveyor of varied information products, contributed
     to benchmark-relative performance during the period. Nasdaq's share price
     rose in response to expanding earnings estimates and a more attractive
     business model. While market volatility over the period boosted trading
     volumes, the vast bulk of the company's revenues are recurring, and not
     reliant on transaction fees. Nasdaq's recurring revenues derive from data
     products and subscription services sold to investment firms. Thanks to its
     excellent cash flow, Nasdaq has been enhancing shareholder value by way of
     dividends* and share repurchases.

     Finally, Lithia Motors, an automobile retailer from the consumer
     discretionary sector, was another Fund holding that contributed to relative
     performance. Lithia has grown through well-integrated acquisitions and the
     resulting efficiencies in managing administrative costs. Once overly
     dependent on Chrysler sales, Lithia now sells Audi, Honda and Toyota
     vehicles among 30 total brands offered at more than 120 retail locations in
     the western and northwestern United States. The company has also done well
     in its used car business, a segment that produces higher margins than new
     car sales.

Q    Which stock selections detracted from the Fund's benchmark-relative
     performance during the 12-month period ended November 30, 2015?

A    Keurig Green Mountain, from the consumer staples sector, was the biggest
     disappointment in the Fund's portfolio during the 12-month period. Poor
     consumer reaction to Keurig's newest line of coffee brewers had the related
     effect of eating into sales of the company's coffee pods. In addition, by

*   Dividends are not guaranteed.

     opening its brewing system to other brands, Keurig lost market share for
     its own Green Mountain coffee pods, which have been more profitable. Keurig
     also introduced its KOLD system for delivering cold drinks during the
     period, and investors were disappointed by the high initial sales prices of
     both the KOLD machines and the pods, which signaled a smaller market
     opportunity for the products than had been anticipated. Due to the many
     issues outlined here, we eliminated the bulk of the portfolio's Keurig
     holding, retaining only a small position that matches the company's
     weighting in the Russell Index.

     The Fund's shares of Cabot Oil & Gas, an exploration-and-production (E&P)
     company, suffered along with the rest of the energy sector during the
     period, and detracted from relative performance. Cabot produces natural
     gas, primarily from its holdings in the Marcellus Shale formation in
     Appalachia, and Cabot is moving aggressively to develop the properties.
     Nevertheless, the company's results fell victim to the sharp decline (more
     than 50%) in the price of natural gas over the 12-month period. We trimmed
     the Fund's position in Cabot, maintaining a small allocation at period end.
     Also in energy, the portfolio's position in Memorial Resource Development
     (MRD), another E&P company, detracted from the Fund's relative returns as
     MRD saw its results severely undercut by falling natural gas prices. We
     continue to hold the MRD position, based on the potential value of the
     company's attractive holdings in Louisiana's Terryville Field.

     In industrials, American Airlines Group, a leading global air carrier, was
     a subpar performer in the Fund's portfolio. American's revenues-per-
     available-passenger-mile, a key metric for the airline industry,
     disappointed investors during the 12-month period. In addition, the market
     has become concerned that fast-growing industry capacity may harm
     American's business. We have retained the Fund's position, however, in the
     belief that the stock's current valuation does not adequately reflect
     American's potential long-term earnings power.

Q    Did the Fund have any exposure to derivatives during the 12-month period
     ended November 30, 2015? If so, did the use of derivatives have any effect
     on the Fund's performance?

A    No. The Fund had no exposure to derivatives during the 12-month period.

Q    What is your outlook as we head into a new calendar year?

A    We are cautiously optimistic on the medium-term outlook for equities,
     although we think volatility is likely to persist into 2016. Earnings for
     U.S. companies seem poised to grow as chaotic commodity markets settle down
     and the U.S. dollar stabilizes relative to other currencies.

                 Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/15 7



     Consumer confidence could get a boost from cheap energy and favorable
     employment trends. Meanwhile, the sluggish pace of global economic growth
     combined with low commodity prices seem likely to contain inflation, thus
     reducing the need for extremely higher interest rates, though the Federal
     Reserve (the Fed) is likely to embark on a course of gradual rate increases
     here in the U.S. over the coming months. Even so, we believe rates will
     remain in a low range for an extended period, given current, relatively
     tame levels of inflation.

     Under these conditions, we believe investors will be willing to pay a
     premium for shares of companies with strong business models that can
     exhibit sustainable growth rates and levels of innovation. We look for all
     of those positive traits when selecting the mid-cap equities we favor
     holding in the Fund's portfolio.

Please refer to the Schedule of Investments on pages 18-25 for a full listing of
Fund securities.

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.

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.

The portfolio invests in REIT securities, the value of which can fall for a
variety of reasons, such as declines in rental income, fluctuating interest
rates, poor property management, environmental liabilities, uninsured damage,
increased competition, or changes in real estate tax laws.

Investing in foreign and/or emerging markets securities involves risks relating
to interest rates, currency exchange rates, economic, and political conditions.

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.

Before investing, consider the product's investment objectives, risks, charges
and expenses. Contact your advisor or Pioneer Investments for a prospectus or
summary prospectus containing this information. Read it carefully.

Index Definition
--------------------------------------------------------------------------------
The Russell Midcap Growth Index is an unmanaged index that measures the
performance of U.S. mid-cap growth stocks. 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 11-15.

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 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 Fund acquired the assets and liabilities of Pioneer Select Mid Cap Growth
Fund ("the predecessor fund") on June 7, 2013 ("the reorganization"). As a
result of the reorganization, the predecessor fund's performance and financial
history became the performance and financial history of the Fund. The
performance of Class A shares of the Fund is the performance of Class A shares
of the predecessor fund for periods prior to the reorganization, and has not
been restated to reflect any differences in expenses.

The predecessor fund was established in connection with the reorganization of
Regions Morgan Keegan Select Mid Cap Growth Fund into the predecessor fund on
May 15, 2009. The performance of Class A shares of the predecessor fund for
periods prior to May 15, 2009, includes the performance of Regions Morgan Keegan
Select Mid Cap Growth Fund's Class A shares, which has been restated to reflect
differences in any applicable sales charges (but not differences in expenses).
This adjustment has the effect of reducing the previously reported performance
of Regions Morgan Keegan Select Mid Cap Growth Fund. A different investment
adviser served as the adviser of Regions Morgan Keegan Select Mid Cap Growth
Fund.

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 K shares for the period prior to the
commencement of operations of Class K shares on December 31, 2014, is 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 K shares, the performance of Class K shares prior to their
inception would have been higher than the performance shown. For the period
beginning December 31, 2014, the actual performance of Class K shares is
reflected. Class K 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

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 R shares are not subject to sales charges and are available for limited
groups of eligible 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 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 Fund acquired the assets and liabilities of Pioneer Select Mid Cap Growth
Fund ("the predecessor fund") on June 7, 2013 ("the reorganization"). As a
result of the reorganization, the predecessor fund's performance and financial
history became the performance and financial history of the Fund. The
predecessor fund did not offer Class R shares. Accordingly, the performance of
Class R shares of the Fund is the performance of Class A shares of the
predecessor fund for periods prior to the reorganization, restated to reflect
the higher distribution and service fees of Class R shares, but not other
differences in expenses.

The predecessor fund was established in connection with the reorganization of
Regions Morgan Keegan Select Mid Cap Growth Fund into the predecessor fund on
May 15, 2009. The performance shown for Class R shares of the Fund for periods
prior to May 15, 2009, is based on the performance of Regions Morgan Keegan
Select Mid Cap Growth Fund's Class A shares, which has been restated to reflect
differences in any applicable sales charges and the higher distribution and
service fees of Class R shares of the Fund (but not differences in expenses).
This adjustment has the effect of reducing the previously reported performance
of Regions Morgan Keegan Select Mid Cap Growth Fund. A different investment
adviser served as the adviser of Regions Morgan Keegan Select Mid Cap Growth
Fund.

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.

     respectively, multiplied by the average account value over the period,
     multiplied by 183/365 (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 | 11/30/15

1. Organization and Significant Accounting Policies

Pioneer Select Mid Cap Growth Fund (the Fund) is one of two portfolios
comprising Pioneer Series Trust II (the Trust), a Delaware statutory trust. The
Fund is registered under the Investment Company Act of 1940 as a diversified,
open-end management investment company. The investment objective of the Fund is
long-term capital growth.

The Fund offered five classes of shares designated as Class A, Class C, Class K,
Class R and Class Y shares. Class B shares were converted to Class A shares as
of the close of business on November 10, 2014. Class K shares commenced
operations on December 31, 2014. 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 of Trustees 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.

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 gains and losses 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:

A.   Security Valuation

     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.

                Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/15 35


     Equity securities that have traded on an exchange are valued by using the
     last sale price on the principal exchange where they are traded. Equity
     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 or, if both last bid and asked prices
     are not available, at the last quoted bid price. Last sale and bid and
     asked prices are provided by independent third party pricing services. In
     the case of equity securities not traded on an exchange, prices are
     typically determined by independent third party pricing services using a
     variety of techniques and methods.

     Foreign securities are valued in U.S. dollars based on foreign currency
     exchange rate quotations supplied by a third party pricing service. Trading
     in non-U.S. equity 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 a fair value model developed by an
     independent pricing service to value non-U.S. equity securities.

     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 by a fair valuation
     team comprised of certain personnel of Pioneer Investment Management, Inc.
     (PIM), the Fund's investment adviser, pursuant to procedures adopted by the
     Fund's Board of Trustees. PIM's fair valuation team uses fair value methods
     approved by the Valuation Committee of the Board of Trustees. PIM's fair
     valuation team is responsible for monitoring developments that may impact
     fair valued securities and for discussing and assessing fair values on an
     ongoing basis, and at least quarterly, with the Valuation Committee of the
     Board of Trustees.

     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. 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. Examples of a significant
     event might include political or economic news, corporate restructurings,
     natural disasters, terrorist activity or trading halts. Thus, the valuation
     of the Fund's securities may differ significantly from exchange prices and
     such differences could be material.

    At November 30, 2015, there were no securities that were valued using fair
    value methods (other than securities valued using prices supplied by
    independent pricing services or broker dealers).

B.   Investment Income and Transactions

     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.

     Security transactions are recorded as of trade date. Gains and losses on
     sales of investments are calculated on the identified cost method for both
     financial reporting and federal income tax purposes.

C.   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 net taxable income and net realized capital gains, if any, to
     its shareowners. Therefore, no provision for federal income taxes is
     required. As of November 30, 2015, the Fund did not accrue any interest or
     penalties with respect to uncertain tax positions, which, if applicable,
     would be recorded as an income tax expense in the Statement of Operations.
     Tax returns filed within the prior three years are subject to examination
     by Federal and State tax authorities.

     The amount and character of income and capital gain distributions to
     shareowners are determined in accordance with federal income tax rules,
     which may differ from U.S. generally accepted accounting principles.
     Distributions in excess of net investment income or net realized gains are
     temporary overdistributions for financial statement purposes resulting from
     differences in the recognition or classification of income or distributions
     for financial statement and tax purposes. Capital accounts within the
     financial statements are adjusted for permanent book/tax differences to
     reflect tax character, but are not adjusted for temporary differences. At
     November 30, 2015, the Fund reclassified $6,020,146 to decrease paid in
     capital, $5,046,239 to increase undistributed net investment income, and
     $973,907 to increase accumulated net realized gain on investments to
     reflect permanent book/tax differences. These adjustments have no impact on
     net assets or the results of operations.

     The tax character of distributions during the year ended November 30, 2015,
     and November 30, 2014, was as follows:



     ---------------------------------------------------------------------------
                                                          2015              2014
     ---------------------------------------------------------------------------
                                                              
     Distributions paid from:
     Ordinary Income                              $         --      $  3,202,734
     Long-term capital gain                        107,708,907       159,324,451
     ---------------------------------------------------------------------------
          Total                                   $107,708,907      $162,527,185
     ===========================================================================


                Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/15 37


     The following shows the components of distributable earnings on a federal
     income tax basis at November 30, 2015:



     ---------------------------------------------------------------------------
                                                                            2015
     ---------------------------------------------------------------------------
                                                                 
     Distributable earnings:
     Undistributed long-term gain                                   $ 19,833,838
     Net unrealized appreciation                                     198,477,714
     ---------------------------------------------------------------------------
          Total                                                     $218,311,552
     ===========================================================================


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

D.   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 $75,813 in underwriting commissions on the sale of
     Class A shares during the year ended November 30, 2015.

E.   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 C and Class R shares of the Fund,
     respectively (see Note 4). Class K and Class Y shares do not pay
     distribution fees. All expenses and fees paid to the Fund's transfer agent,
     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, Class K, Class R and Class
     Y shares can reflect different transfer agent and distribution expense
     rates.

F.   Risks

     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

38 Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/15


     risks affecting these industries or 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.

2. Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's
portfolio. Management fees are calculated daily at an annual rate equal to
0.625% of the Fund's average daily net assets up to $500 million, 0.60% of the
next $500 million and 0.575% on assets over $1 billion. For the year ended
November 30, 2015, the effective management fee was equivalent to 0.60% of the
Fund's average daily net assets.

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
$114,217 in management fees, administrative costs and certain other
reimbursements payable to PIM at November 30, 2015.

3. Transfer Agent

Prior to November 2, 2015, Pioneer Investment Management Shareholder Services,
Inc. (PIMSS), a wholly owned indirect subsidiary of UniCredit, provided
substantially all transfer agent and shareowner services to the Fund at
negotiated rates.

Effective November 2, 2015, Boston Financial Data Services serves as the
transfer agent to the Fund at negotiated rates.

In addition, the Fund reimbursed the transfer agent for out-of-pocket expenses
incurred by the transfer agent related to shareholder communications activities
such as proxy and statement mailings, outgoing phone calls and omnibus
relationship contracts. For the year ended November 30, 2015, such out-of-
pocket expenses by class of shares were as follows:



--------------------------------------------------------------------------------
Shareholder Communications:
--------------------------------------------------------------------------------
                                                                   
Class A                                                               $  712,767
Class C                                                                   99,285
Class R                                                                   42,835
Class Y                                                                  169,601
--------------------------------------------------------------------------------
  Total                                                               $1,024,488
================================================================================


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $178,192 in transfer agent fees and out-of-pocket reimbursements
payable to PIMSS at November 30, 2015.

                Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/15 39


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. Pursuant to the Plan, the Fund further pays PFD
0.50% of the average daily net assets attributable to Class R shares for
distribution services. Included in "Due to affiliates" reflected on the
Statement of Assets and Liabilities is $48,372 in distribution fees payable to
PFD at November 30, 2015.

The Fund also has adopted a separate service plan for Class R shares (Service
Plan). The Service Plan authorizes the Fund to pay securities dealers, plan
administrators or other service organizations that agree to provide certain
services to retirement plans or plan participants holding shares of the Fund a
service fee of up to 0.25% of the Fund's average daily net assets attributable
to Class R shares held by such plans.

In addition, redemptions of each class of shares (except Class K, Class R and
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 K, Class R and Class Y shares. Proceeds
from the CDSCs are paid to PFD. For the year ended November 30, 2015, CDSCs in
the amount of $5,569 were paid to PFD.

5. Expense Offset Arrangements

The Fund entered into certain expense offset arrangements with PIMSS. For the
year ended November 30, 2015, 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 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. The
credit

40 Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/15


facility in effect until June 9, 2015, was in the amount of $215 million. As of
June 9, 2015, the facility is in the amount of $240 million. Under such
facility, depending on the type of loan, interest on borrowings is payable at
the London Interbank Offered Rate (LIBOR) plus 0.85% on an annualized basis, or
the Alternate Base Rate, which is the greater of (a) the facility's
administrative agent's daily announced prime rate on the borrowing date, (b) 2%
plus the Federal Funds Rate on the borrowing date and (c) 2% plus the overnight
Eurodollar rate on the borrowing date. The Funds pay an annual commitment fee to
participate in a credit facility. The commitment fee is allocated among
participating Funds based on an allocation schedule set forth in the credit
agreement. For the year ended November 30, 2015, the Fund had no borrowings
under the credit facility.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Pioneer Series Trust II and Shareowners of Pioneer
Select Mid Cap Growth Fund:
--------------------------------------------------------------------------------
We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Pioneer Select Mid Cap Growth Fund (one of the
funds constituting Pioneer Series Trust II), as of November 30, 2015, and the
related statement of operations for the year then ended and the statements of
changes in net assets and the financial highlights for each of the two years in
the period then ended. 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. The financial highlights for the years ended November 30, 2013, 2012,
and 2011 were audited by other auditors. Those auditors expressed an unqualified
opinion on those financial statements and financial highlights in their report
dated January 24, 2014.

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. The Fund
is not required to have, nor were we engaged to perform, an audit of its
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, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of November 30, 2015, by correspondence with the
custodian and brokers; where replies were not received from brokers, we
performed other auditing procedures. 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 Select Mid Cap Growth Fund as of November 30, 2015, and the results of
its operations for the year then ended and the changes in its net assets and the
financial highlights for each of the two years in the period then ended, in
conformity with accounting principles generally accepted in the United States of
America.

Additional Information (unaudited)

PIM, the Fund's investment adviser, is currently an indirect, wholly owned
subsidiary of UniCredit. On November 11, 2015, UniCredit announced that it
signed a binding master agreement with Banco Santander and affiliates of Warburg
Pincus and General Atlantic (the "Private Equity Firms") with respect to Pioneer
Investments ("Pioneer") and Santander Asset Management ("SAM") (the
"Transaction").

The Transaction, as previously announced by UniCredit, will establish a holding
company, with the name Pioneer Investments, to be owned by UniCredit (50%) and
the Private Equity Firms (50% between them). The holding company will control
Pioneer's U.S. operations, including the Adviser. The holding company also will
own 66.7% of Pioneer's and SAM's combined operations outside the U.S., while
Banco Santander will own directly the remaining 33.3% stake. The closing of the
Transaction is expected to happen in 2016, subject to certain regulatory and
other approvals.

Under the Investment Company Act of 1940, completion of the Transaction will
cause the Fund's current investment advisory agreement with PIM to terminate.
Accordingly, the Fund's Board of Trustees will be asked to approve a new
investment advisory agreement. If approved by the Board, the Fund's new
investment advisory agreement will be submitted to the shareholders of the Fund
for their approval.

                Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/15 43


Approval of Investment Advisory Agreement

Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to
Pioneer Select Mid Cap Growth Fund (the Fund) pursuant to an investment advisory
agreement between PIM and the Fund. In order for PIM to remain the investment
adviser of the Fund, the Trustees of the Fund must determine annually whether to
renew the investment advisory agreement for the Fund.

The contract review process began in January 2015 as the Trustees of the Fund
agreed on, among other things, an overall approach and timeline for the process.
Contract review materials were provided to the Trustees in March 2015 and July
2015. Supplemental contract review materials were provided to the Trustees in
September 2015. In addition, the Trustees reviewed and discussed the Fund's
performance at regularly scheduled meetings throughout the year and took into
account other information related to the Fund provided to the Trustees at
regularly scheduled meetings in connection with the review of the Fund's
investment advisory agreement.

In March 2015, the Trustees, among other things, discussed the memorandum
provided by Fund counsel that summarized the legal standards and other
considerations that are relevant to the Trustees in their deliberations
regarding the renewal of the investment advisory agreement, and reviewed and
discussed the qualifications of the investment management teams, as well as the
level of investment by the Fund's portfolio managers in the Fund. In July 2015,
the Trustees, among other things, reviewed the Fund's management fee and total
expense ratios, the financial statements of PIM and its parent companies, the
profitability analyses provided by PIM, and possible economies of scale. The
Trustees also reviewed the profitability of the institutional business of PIM
and PIM's affiliate, Pioneer Institutional Asset Management, Inc. (together with
PIM, "Pioneer"), as compared to that of PIM's fund management business, and
considered the differences between the fees and expenses of the Fund and the
fees and expenses of Pioneer's institutional accounts, as well as the different
services provided by PIM to the Fund and by Pioneer to the institutional
accounts. The Trustees further considered contract review materials in September
2015.

At a meeting held on September 15, 2015, based on their evaluation of the
information provided by PIM and third parties, the Trustees of the Fund,
including the Independent Trustees voting separately, unanimously approved the
renewal of the investment advisory agreement for another year. In approving the
renewal of the investment advisory agreement, the Trustees considered various
factors that they determined were relevant, including the factors described
below. The Trustees did not identify any single factor as the controlling factor
in determining to approve the renewal of the agreement.

44 Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/15


Nature, Extent and Quality of Services

The Trustees considered the nature, extent and quality of the services that had
been provided by PIM to the Fund, taking into account the investment objective
and strategy of the Fund. The Trustees also reviewed PIM's investment approach
for the Fund and its research process. The Trustees considered the resources of
PIM and the personnel of PIM who provide investment management services to the
Fund. They also reviewed the amount of non-Fund assets managed by the portfolio
managers of the Fund. The Trustees considered the non-investment resources and
personnel of PIM involved in PIM's services to the Fund, including PIM's
compliance and legal resources and personnel. The Trustees noted the substantial
attention and high priority given by PIM's senior management to the Pioneer fund
complex.

The Trustees considered that PIM supervises and monitors the performance of the
Fund's service providers and provides the Fund with personnel (including Fund
officers) and other resources that are necessary for the Fund's business
management and operations. The Trustees also considered that, as administrator,
PIM is responsible for the administration of the Fund's business and other
affairs. The Trustees considered the fees paid to PIM for the provision of
administration services.

Based on these considerations, the Trustees concluded that the nature, extent
and quality of services that had been provided by PIM to the Fund were
satisfactory and consistent with the terms of the investment advisory agreement.

Performance of the Fund

In considering the Fund's performance, the Trustees regularly review and discuss
throughout the year data prepared by PIM and information comparing the Fund's
performance with the performance of its peer group of funds as classified by
each of Morningstar, Inc. (Morningstar) and Lipper, and with the performance of
the Fund's benchmark index. They also discuss the Fund's performance with PIM on
a regular basis. The Trustees' regular reviews and discussions were factored
into the Trustees' deliberations concerning the renewal of the advisory
agreement.

Management Fee and Expenses

The Trustees considered information showing the fees and expenses of the Fund in
comparison to the management fees and expense ratios of its peer group of funds
as classified by Morningstar and also to the expense ratios of a peer group of
funds selected on the basis of criteria determined by the Independent Trustees
for this purpose using data provided by Strategic Insight

                Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/15 45


Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent
third party. In all quintile rankings referred to below, first quintile is most
favorable to the Fund's shareowners.

The Trustees considered that the Fund's management fee for the most recent
fiscal year was in the first quintile relative to the management fees paid by
other funds in its Morningstar peer group for the comparable period. The
Trustees also considered the breakpoints in the management fee schedule and the
reduced fee rates above certain asset levels. The Trustees considered that the
expense ratio of the Fund's Class A shares for the most recent fiscal year was
in the second quintile relative to its Morningstar peer group and in the first
quintile relative its Strategic Insight peer group, in each case for the
comparable period. The Trustees considered the impact of transfer agency,
sub-transfer agency, and other non-management fee expenses on the expense ratios
of the Fund. The Trustees noted that they separately review the Fund's transfer
agency, sub-transfer agency and intermediary arrangements.

The Trustees reviewed management fees charged by Pioneer to institutional and
other clients, including publicly offered European funds sponsored by affiliates
of Pioneer, unaffiliated U.S. registered investment companies (in a sub-advisory
capacity), and unaffiliated foreign and domestic separate accounts. The Trustees
also considered PIM's costs in providing services to the Fund and Pioneer's
costs in providing services to the other clients and considered the differences
in management fees and profit margins for Fund and non-Fund services. In
evaluating the fees associated with Pioneer's client accounts, the Trustees took
into account the respective demands, resources and complexity associated with
the Fund and client accounts. The Trustees noted that, in some instances, the
fee rates for those clients were lower than the management fee for the Fund and
considered that, under the investment advisory agreement with the Fund, PIM
performs additional services for the Fund that it does not provide to those
other clients or services that are broader in scope, including oversight of the
Fund's other service providers and activities related to compliance and the
extensive regulatory and tax regimes to which the Fund is subject. The Trustees
also considered the different entrepreneurial risks associated with PIM's
management of the Fund and Pioneer's management of the other client accounts.

The Trustees concluded that the management fee payable by the Fund to PIM was
reasonable in relation to the nature and quality of the services provided by PIM
to the Fund.

Profitability

The Trustees considered information provided by PIM regarding the profitability
of PIM with respect to the advisory services provided by PIM to the Fund,
including the methodology used by PIM in allocating certain of its

46 Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/15


costs to the management of the Fund. The Trustees also considered PIM's profit
margin in connection with the overall operation of the Fund. They further
reviewed the financial results realized by PIM and its affiliates from non-fund
businesses. The Trustees considered PIM's profit margins with respect to the
Fund in comparison to the limited industry data available and noted that the
profitability of any adviser was affected by numerous factors, including its
organizational structure and method for allocating expenses. The Trustees
concluded that PIM's profitability with respect to the management of the Fund
was not unreasonable.

Economies of Scale

The Trustees considered PIM's views relating to economies of scale in connection
with the Pioneer Funds as fund assets grow and the extent to which any such
economies of scale are shared with funds and fund shareholders. The Trustees
noted the breakpoints in the management fee schedule. The Trustees recognize
that economies of scale are difficult to identify and quantify, and that, among
other factors that may be relevant, are the following: fee levels, expense
subsidization, investment by PIM in research and analytical capabilities and
PIM's commitment and resource allocation to the Fund. The Trustees noted that
profitability also may be an indicator of the availability of any economies of
scale, although profitability may vary for other reasons including reductions in
expenses. The Trustees concluded that economies of scale, if any, were being
appropriately shared with the Funds.

Other Benefits

The Trustees considered the other benefits to PIM from its relationship with the
Fund. The Trustees considered the character and amount of fees paid by the Fund,
other than under the investment advisory agreement, for services provided by PIM
and its affiliates. The Trustees further considered the revenues and
profitability of PIM's businesses other than the fund business. Pioneer is the
principal U.S. asset management business of Pioneer Global Asset Management, the
worldwide asset management business of UniCredit Group, which manages over $150
billion in assets (including the Funds). Pioneer and the Funds receive
reciprocal intangible benefits from the relationship, including mutual brand
recognition and, for the Funds, direct and indirect access to the resources of a
large global asset manager. The Trustees concluded that any such benefits
received by Pioneer as a result of its relationship with the Funds were
reasonable and their consideration of the advisory agreement between the Fund
and PIM and the fees thereunder were unaffected by Pioneer's possible receipt of
any such intangible benefits.

Conclusion

After consideration of the factors described above as well as other factors, the
Trustees, including all of the Independent Trustees, concluded that the
investment advisory agreement between PIM and the Fund, including the fees
payable thereunder, was fair and reasonable and voted to approve the proposed
renewal of the investment advisory agreement for the Fund.

 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.

                 not performed by the Audit

                 typically well-defined and

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

o At least quarterly, the Audit Committee shall review a report summarizing the
  services by service category, including fees, provided by the Audit firm as
  set forth in the above policy.

under the Exchange Act (17 CFR 240.13a-15(b) or 240.15d-15(b)).

The registrant's principal executive officer
