President's Letter

Robust, synchronized global economic growth and rising corporate profits drove
strong performance in both the credit and equity markets for the first three
quarters of 2017. U.S. stocks, as measured by the Standard & Poor's 500 Index,
had returned 14.23% from January 1, 2017, through September 30, 2017.
Fixed-income markets, while not generating the same dazzling returns as
equities, held their own, led by high-yield securities, which produced a return
of 7.05% in the U.S., as measured by the ICE Bank of America Merrill Lynch U.S.
High Yield Index. Meanwhile, the Bloomberg Barclays U.S. Aggregate Bond Index
returned 3.14% for the first three quarters of calendar year 2017.

Continued strong employment numbers and higher consumer confidence, together
with solid global economic growth and a depreciating U.S. dollar contributed to
better-than-expected U.S. gross domestic product (GDP) growth of more than 3% in
both the second and third quarters of 2017. Outside the U.S., economic growth
also surprised to the upside across the Euro zone, China, and Japan. Meanwhile,
despite higher oil and commodities prices, inflation continued to be moderate,
both in the U.S. and globally, enabling major non-U.S. central banks to maintain
their easy monetary policies. As expected, however, the U.S. Federal Reserve
System (the Fed) began tapering its balance sheet in October. The Fed also
appears primed to raise interest rates a few more times in 2018, as it continues
to withdraw monetary stimulus.

As we transition into 2018, we believe the U.S. economy will experience modest
growth in the short term, depending on the mix of economic policies enacted as
the country moves away from monetary stimulus (driven by the Fed) and toward
fiscal stimulus (including tax reform) as well as lighter regulatory burdens.
Meanwhile, corporate earnings remain solid and we think they will improve even
further, despite the possibility of some pressure from wage increases. In
addition, it is our view that the economy will continue to grow and that we may
begin to see a modest upturn in inflation. In that scenario, we anticipate that
the Fed will continue to raise interest rates.

While economic and market conditions appear solid, there are always risks to
consider that could dampen the outlook. Geopolitical concerns, such as increased
tensions with North Korea, and continued political gridlock in Washington are
just some of the risks that could lead to increased market volatility.

Portfolio Management Discussion | 11/30/17

In the follow interview, Madelynn Matlock discusses the market environment for
international equities and the factors that influenced the performance of
Pioneer International Equity Fund during the 12-month period ended November 30,
2017. Ms. Matlock, a senior vice president and a portfolio manager at Amundi
Pioneer Asset Management, Inc. (Amundi Pioneer), and Marco Pirondini, Executive
Vice President, Head of Equities, U.S., and a portfolio manager at Amundi
Pioneer, are responsible for the day-to-day management of the Fund.

Q    How did the Fund perform during the 12-month period ended November
     30, 2017?

A    Pioneer International Equity Fund's Class A shares returned 28.24% at net
     asset value during the 12-month period ended November 30, 2017, while the
     Fund's benchmark, the Morgan Stanley Capital International (MSCI) Europe,
     Australasia, Far East (EAFE) ND Index (the MSCI EAFE Index)(1), returned
     27.27%. During the same period, the average return for the 432 mutual funds
     in Lipper's International Multi-Cap Core Funds category was 26.53%, and the
     average return of the 754 mutual funds in Morningstar's Foreign Large Blend
     Funds category was 25.95%.

Q    How would you characterize the investment environment for international
     equities during the 12-month period ended November 30, 2017?

A    With the help of continued monetary support from foreign central banks and
     a reflationary bias in the global economy, international equities enjoyed
     strong performance during the past 12 months. The market-friendly election
     outcomes in France and the Netherlands added to investor confidence in
     European equities. In fact, despite the uncertainty over the United
     Kingdom's (U.K.) potential "Brexit" from the European Union (E.U.) in the
     wake of the U.K. government's triggering of the Article 50 E.U. treaty
     withdrawal provision in March 2017, the lack of a sustained economic
     recovery in Japan, and the risk of more protectionist U.S. trade policies,
     the Fund's benchmark, the MSCI EAFE Index, outperformed U.S. stocks by a

     wide margin. The MSCI EAFE Index returned 27.27% for the period, while
     the Standard & Poor's 500 Index, a broad measure of the U.S. stock market,
     returned 22.86%.

     From a regional perspective, both developing and developed markets rallied
     during the period, led by the emerging markets, Europe, and Japan, which
     returned 33%, 30%, and 24%, respectively. From a sector perspective,
     information technology, materials, and industrials, which were up by 44%,
     32%, and 31%, respectively, were the strongest performers within the Fund's
     benchmark. Meanwhile, real estate, while posting a very solid 19% return
     for the 12 months, still lagged the overall market in what was a very
     positive period for equities in general.

Q    Which of your investment strategies or individual portfolio holdings
     contributed to the Fund's benchmark-relative performance results during the
     12-month period ended November 30, 2017?

A    Stock selection in information technology was advantageous for the Fund's
     benchmark-relative returns during the period, especially in the
     semiconductor industry. Within semiconductors, the portfolio's position in
     Tokyo Electron was a key contributor to the Fund's relative performance.
     Tokyo Electron is one of the most respected manufacturers of equipment used
     for the production of semiconductor chips, and the company saw strong
     demand for its products over the 12-month period. Chips are increasingly
     finding their way into new products and applications, from light bulbs and
     cars to industrial equipment. That trend is likely to continue for the
     foreseeable future, and we believe Tokyo Electron is in a favorable
     position to continue benefiting from heightened chip demand.

     Another strong contributor to the Fund's benchmark-relative performance
     during the period was a position in Yaskawa. The Japanese-based company saw
     rising profits based on its ability to deliver high-quality industrial
     robots and fully integrated robotic automation systems that empower
     customers to compete globally.

     From a regional perspective, our decision to overweight the Fund to
     investments in Europe augmented relative performance, as did stock
     selection results in that region. The Fund's position in the U.K.
     homebuilder Persimmon was a strong contributor to benchmark-relative
     returns during the period, as the company's stock price climbed in response
     to robust customer demand and strong profit announcements.

     Finally, while the Fund's exposure to the emerging markets was limited, the
     portfolio's investments in Taiwan-based Accton and Samsung Electronics in
     South Korea aided relative performance.

                  Pioneer International Equity Fund | Annual Report | 11/30/17 5


Q    Which of your investment strategies or individual portfolio holdings
     detracted from the Fund's benchmark-relative performance during the
     12-month period ended November 30, 2017?

A    The Fund's investments in oil-and-gas equipment services company
     Schlumberger struggled during the period due to the oversupply of oil and
     the potential for reduced demand given the continued development of
     alternative energy sources. With management's forward guidance suggesting
     that the current supply/demand imbalance may affect Schlumberger's earnings
     in the second half of 2017 and into 2018, we sold the portfolio's position
     during the first half of the 12-month period.

     A position in Shire, a U.K. biotechnology company, also detracted from the
     Fund's performance, primarily because of concerns about the company's
     position in some of its important product markets. With several potential
     catalysts failing to propel the stock higher, we sold the portfolio's
     position in the second half of the period and reallocated the proceeds into
     other investments that we believe have stronger growth prospects.

     The Fund's investment in BAE Systems was another drag on benchmark-relative
     performance during the period. This British defense-and-aeronautics company
     appeared to be on track to receive several large orders, but the orders
     never materialized. However, we continue to hold the stock in the
     portfolio, as we expect defense spending - which has bottomed within the
     context of typical 7- to 10-year historical cycles - to rise in the coming
     years. We believe developed countries are likely to spend more on defense
     due to an increasingly uncertain geopolitical backdrop and the potential
     for less support from the United States.

Q    Did you make any noteworthy shifts in the Fund's strategy or allocations
     during the 12-month period ended November 30, 2017?

A    We did not make any notable shifts in the Fund's geographic and sector
     allocations, but we did trim some individual stock positions that had
     experienced significant price appreciation. Those decisions resulted in
     some reduction in the portfolio's allocation to Japan at the country level,
     and to basic materials at the sector level.

     We are continually tweaking the Fund's holdings from a portfolio-
     construction vantage, sizing individual positions at the security,
     industry, and sector level in an effort to help maximize returns and limit
     risk. As of November 30, 2017, the Fund had overweight exposures relative
     to the MSCI EAFE Index in information technology and industrials, and
     underweights to financials and health care.

6 Pioneer International Equity Fund | Annual Report | 11/30/17


Q    Did the Fund have any derivative exposure during the 12-month period ended
     November 30, 2017?

A    No, we did not invest the Fund in derivative securities during the period.

Q    What is your outlook for international equities as we head into a new
     calendar year, and how are you positioning the Fund?

A    We believe central-bank policies will continue to exert a meaningful
     influence on the markets in 2018. In the United States, where the economy
     is well into its recovery, the Federal Reserve has begun tightening
     monetary policy by gradually raising its benchmark short-term interest rate
     and reducing its balance sheet, which grew substantially through its three
     quantitative-easing programs from 2008-2014. In international markets,
     where economies are improving but still lag the U.S., the details and
     timetables of monetary policy changes at the bellwether European Central
     Bank and the Bank of Japan will have broad implications for economic growth
     as their outlooks shift from accommodation to tightening over the next
     couple of years.

     In this environment, we believe international equities could trend higher
     in 2018 due to a global economic expansion and the potential for fiscal
     stimulus initiatives, such as tax reform in the U.S. In such a reflationary
     environment, we believe cyclical and consumer stocks may outperform, and we
     are focusing the Fund's exposure on investments in those areas. We continue
     to find positive potential in technology, as advancements spread into more
     of the products and services we use daily. On the other hand, we hold a
     more skeptical outlook for the energy sector, which we believe is facing a
     supply overhang as the continued growth in alternative energy sources
     erodes stable, long-term returns as well as asset values of fossil fuels.

     Given high current market valuations and geopolitical tensions, however, we
     will temper our sanguine outlook with some caution. To help mitigate some
     of those risks in the portfolio, we continue to focus on holding stocks of
     quality companies with high returns on capital, sustainable competitive
     advantages, and low debt levels as compared with their peers.

Index Definition
--------------------------------------------------------------------------------
The MSCI EAFE ND Index is an unmanaged, commonly used measure of international
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 11-13.

Call 1-800-225-6292 or visit www.amundipioneer.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 the contractual expense limitation currently in
effect through April 1, 2019, for Class A shares. There can be no assurance
that Amundi 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.

Please refer to the financial highlights for a more current expense ratio.

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. For the period
beginning April 16, 2009, the actual performance of Class Y shares is
reflected. 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 April 1, 2019, for Class Y shares. There can be no assurance
that Amundi 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.

Please refer to the financial highlights for a more current expense ratio.

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.

     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), 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 | 11/30/17

1. Organization and Significant Accounting Policies

Pioneer International Equity Fund (the "Fund") is the sole portfolio comprising
Pioneer Series Trust VIII, 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 growth of
capital.

The Fund offered 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 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.

On July 3, 2017, Amundi acquired Pioneer Investments, a group of asset
management companies located throughout the world. Amundi, one of the world's
largest asset managers, is headquartered in Paris, France. As a result of the
transaction, Pioneer Investment Management, Inc., the Fund's investment adviser,
became an indirect wholly owned subsidiary of Amundi and Amundi's wholly owned
subsidiary, Amundi USA, Inc. Prior to July 3, 2017, Pioneer Investments was
owned by Pioneer Global Asset Management S.p.A., a wholly owned subsidiary of
UniCredit S.p.A.

In connection with the transaction, the names of the Fund's investment adviser
and principal underwriter changed. Effective July 3, 2017, the name of Pioneer
Investment Management, Inc. changed to Amundi Pioneer Asset Management, Inc.
(the "Adviser") and the name of Pioneer Funds Distributor, Inc. changed to
Amundi Pioneer Distributor, Inc. (the "Distributor").

                 Pioneer International Equity Fund | Annual Report | 11/30/17 29


In October 2016, the Securities and Exchange Commission ("SEC") released its
Final Rule on Investment Company Reporting Modernization. In addition to
introducing two new regulatory reporting forms (Form N-PORT and Form N-CEN), the
Final Rule amends Regulation S-X, which impacts financial statement
presentation, particularly related to the presentation of derivative
instruments. The Fund's financial statements were prepared in compliance with
the amendments to Regulation S-X.

The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles ("U.S. GAAP") that require the
management of the Fund to 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 Fund is an investment company and follows investment company accounting and
reporting guidance under U.S. GAAP. 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.

     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.

     The value of foreign securities is translated into U.S. dollars based on
     foreign currency exchange rate quotations supplied by third party pricing
     source. Trading in non-U.S. equity securities is substantially completed
     each day at various times prior to the close of 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. securities.

30 Pioneer International Equity Fund | Annual Report | 11/30/17


     Securities for which independent pricing services or broker-dealers 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 the Adviser, pursuant
     to procedures adopted by the Fund's Board of Trustees. The Adviser's fair
     valuation team uses fair value methods approved by the Valuation Committee
     of the Board of Trustees. The Adviser'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, 2017, no securities were valued using fair value methods
     (other than securities valued using prices supplied by independent pricing
     services, broker-dealer or using a third party insurance industry pricing
     model).

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, 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
     and net of income accrued on defaulted securities.

     Interest and dividend income payable by delivery of additional shares is
     reclassified as PIK (payment in kind) income upon receipt and is included
     in interest and dividend income, respectively.

     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.

                 Pioneer International Equity Fund | Annual Report | 11/30/17 31


C.   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
     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
     the market price of those securities but are included with the net realized
     and unrealized gain or loss on investments.

D.   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, 2017, 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 remain subject to
     examination by federal and state tax authorities.

     In addition to meeting the requirements of the Internal Revenue Code, the
     Fund may be required to pay local taxes on the recognition of capital gains
     and/or the repatriation of foreign currencies in certain countries. During
     the year ended November 30, 2017, the Fund paid no such taxes.

     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. GAAP. 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, 2017, the Fund reclassified $138,112 to increase
     undistributed net investment income, $109,104,796 to decrease accumulated
     net realized loss on investments and $109,242,908 to decrease paid-in
     capital to reflect permanent book/tax differences. These adjustments have
     no impact on net assets or the results of operations.

32 Pioneer International Equity Fund | Annual Report | 11/30/17


     At November 30, 2017, the Fund was permitted to carry forward indefinitely
     $2,063,325 of short-term losses under the Regulated Investment Company
     Modernization Act of 2010 without limitation.

     During the year ended November 30, 2017, a capital loss carryforward of
     $8,933,286 was utilized to offset net realized gains by the Fund.

     The tax character of distributions paid during the fiscal year ended
     November 30, 2017 and November 30, 2016 were as follows:



     ---------------------------------------------------------------------------
                                                     2017                   2016
     ---------------------------------------------------------------------------
                                                                
     Distributions paid from:
     Ordinary income                           $1,556,373             $3,049,827
     ---------------------------------------------------------------------------
        Total                                  $1,556,373             $3,049,827
     ===========================================================================


     The following shows the components of distributable earnings on a federal
     income tax basis at November 30, 2017:



     ---------------------------------------------------------------------------
                                                                           2017
     ---------------------------------------------------------------------------
                                                                
     Distributable earnings:
     Undistributed ordinary income                                  $ 3,640,749
     Capital loss carryforward                                       (2,063,325)
     Net unrealized appreciation                                     30,792,668
     ---------------------------------------------------------------------------
        Total                                                       $32,370,092
     ===========================================================================


     The difference between book-basis and tax-basis net unrealized appreciation
     is attributable to the tax deferral of losses on wash sales and adjustments
     relating to Passive Foreign Investment Companies (PFICs).

E.   Fund Shares

     The Fund records sales and repurchases of its shares as of trade date. The
     Distributor earned $10,039 in underwriting commissions on the sale of Class
     A shares during the year ended November 30, 2017.

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 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 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).

                 Pioneer International Equity Fund | Annual Report | 11/30/17 33


     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.

G.   Risks

     The value of securities held by the fund may go up or down, sometimes
     rapidly or unpredictably, due to general market conditions, such as real or
     perceived adverse economic, political or regulatory conditions, inflation,
     changes in interest rates, lack of liquidity in the bond markets or adverse
     investor sentiment. In the past several years, financial markets have
     experienced increased volatility, depressed valuations, decreased liquidity
     and heightened uncertainty. These conditions may continue, recur, worsen or
     spread.

     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.

     Investing in foreign and/or emerging markets securities involves risks
     relating to interest rates, currency exchange rates and economic and
     political conditions. The Fund may invest a substantial amount of its
     assets in issuers located in a limited number of countries and therefore is
     susceptible to adverse economic, political or regulatory developments
     affecting those countries.

2. Management Agreement

The Adviser manages the Fund's portfolio. Management fees are calculated daily
at the annual rate of 0.85% of the Fund's average daily net assets up to $500
million and 0.75% on assets over $500 million. For the year ended November 30,
2017, the effective management fee (excluding waivers and/or assumptions of
expenses) was equivalent to 0.85% of the Fund's average daily net assets.

Effective August 1, 2017, the Adviser contractually agreed to limit ordinary
operating expenses (ordinary operating expenses means all fund expenses other
than extraordinary expenses, such as litigation, taxes, brokerage commissions
and acquired fund fees and 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. Prior to
August 1, 2017, the adviser had contractually agreed to limit ordinary expenses
to 1.45% and 2.35% for Class A and Class C shares, respectively, and Class Y
shares did

34 Pioneer International Equity Fund | Annual Report | 11/30/17


not have an expense limitation. Fees waived and expenses reimbursed during the
year ended November 30, 2017, are reflected on the Statement of Operations.
These expense limitations will be in effect through April 1, 2019. There can be
no assurance that the Adviser 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
$26,411 in management fees, administrative costs and certain other
reimbursements payable to the Adviser, at November 30, 2017.

3. Transfer Agent

Boston Financial Data Services, Inc. serves as the transfer agent to the Fund
at negotiated rates. Transfer agent fees and payables shown on the Statement of
Operations and the Statement of Assets and Liabilities, respectively, include
sub-transfer agent expenses incurred through the Fund's omnibus relationship
contracts.

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 and outgoing phone calls. For the year
ended November 30, 2017, such out-of-pocket expenses by class of shares were as
follows:



--------------------------------------------------------------------------------
Shareowner Communications
--------------------------------------------------------------------------------
                                                                     
 Class A                                                                $68,221
 Class C                                                                  9,081
--------------------------------------------------------------------------------
   Total                                                                $77,302
================================================================================


4. Distribution Plan

The Fund has adopted a distribution plan (the "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 the Distributor, 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 the
Distributor, 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

                 Pioneer International Equity Fund | Annual Report | 11/30/17 35


shares. Included in "Due to affiliates" reflected on the Statement of Assets
and Liabilities is $5,158 in distribution fees payable to the Distributor at
November 30, 2017.

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 12 months 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 the
Distributor. For the year ended November 30, 2017, no CDSCs were paid to the
Distributor.

5. 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 facility in which the Fund participated until February 9, 2016 was in
the amount of $240 million. The credit facility in which the fund participated
until February 7, 2017, was in the amount of $220 million. Effective February
8, 2017, the Fund participates in a facility that is in the amount of $25
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, 2017, 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 VIII and the Shareholders of
Pioneer International Equity Fund:
--------------------------------------------------------------------------------
We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Pioneer International Equity Fund (the "Fund")
(the sole fund constituting Pioneer Series Trust VIII), as of November 30,
2017, and the related statements of operations, changes in net assets and the
financial highlights for the year then ended and the financial highlights for
the year ended November 30, 2013. 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 audit. The statement of changes in net assets for the year ended
November 30, 2016 and the financial highlights for periods ended November 30,
2014, November 30, 2015 and November 30, 2016 were audited by another
independent registered public accounting firm whose report, dated January 25,
2017, expressed an unqualified opinion on the statement of changes in net
assets and those financial highlights.

We conducted our audit 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 audit of the Fund's internal
control over financial reporting. Our audit 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 November 30, 2017, by correspondence
with the custodian, brokers and others or by other appropriate auditing
procedures where replies from brokers and others were not received. We believe
that our audit provides 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 International Equity Fund at November 30, 2017, the results of its
operations, the changes in its net assets, and the financial highlights for the
year then ended and the financial highlights for the year ended November 30,
2013, in conformity with U.S. generally accepted accounting principles.

ADDITIONAL INFORMATION (unaudited)

Change in Independent Registered Public Accounting Firm

Prior to July 3, 2017 Pioneer Investment Management, Inc. (the "Adviser"), the
Fund's investment adviser, was an indirect, wholly owned subsidiary of
UniCredit S.p.A. ("UniCredit"). On that date, UniCredit completed the sale of
its Pioneer Investments business, which includes the Adviser, to Amundi (the
"Transaction").  As a result of the Transaction, the Adviser became an
indirect, wholly owned subsidiary of Amundi. Amundi is controlled by Credit
Agricole S.A. Amundi is headquartered in Paris, France, and, as of September
30, 2016, had more than $1.1 trillion in assets under management worldwide.

Deloitte & Touche LLP ("D&T"), the Fund's previous independent registered
public accounting firm, informed the Audit Committee and the Board that it
would no longer be independent with respect to the Funds upon the completion of
the Transaction as a result of certain services being provided to Amundi and
Credit Agricole, and, accordingly, that it intended to resign as the Fund's
independent registered public accounting firm upon the completion of the
Transaction. D&T's resignation was effective on July 3, 2017, when the
Transaction was completed.

During the periods as to which D&T has served as the Fund's independent
registered public accounting firm, including the Fund's two most recent fiscal
years, D&T's reports on the Fund's financial statements have not contained an
adverse opinion or disclaimer of opinion and have not been qualified or
modified as to uncertainty, audit scope or accounting principles. Further,
there have been no disagreements with D&T on any matter of accounting
principles or practices, financial statement disclosure, or auditing scope or
procedure, which, if not resolved to the satisfaction of D&T, would have caused
D&T to make reference to the subject matter of the disagreement in connection
with its report on the financial statements. In addition, there have been no
reportable events of the kind described in Item 304(a)(1)(v) of Regulation S-K
under the Securities Exchange Act of 1934.

Effective immediately following the completion of the Transaction on July 3,
2017, the Board, acting upon the recommendation of the Audit Committee, engaged
a new independent registered public accounting firm, Ernst & Young LLP ("EY"),
for the Fund's fiscal year ended November 30, 2017.

Prior to its engagement, EY had advised the Fund's Audit Committee that EY had
identified the following matters, in each case relating to services rendered by
other member firms of Ernst & Young Global Limited, all of which are located
outside the United States, to UniCredit and certain of its subsidiaries during
the period commencing July 1, 2016, that it determined to be inconsistent with
the auditor independence rules set forth by the Securities

38 Pioneer International Equity Fund | Annual Report | 11/30/17


and Exchange Commission ("SEC"): (a) project management support services to
UniCredit in the Czech Republic, Germany, Italy, Serbia and Slovenia in
relation to twenty-two projects, that were determined to be inconsistent with
Rule 2-01(c)(4)(vi) of Regulation S-X (management functions); (b) two
engagements for UniCredit in Italy where fees were contingent/success based and
that were determined to be inconsistent with Rule 2-01(c)(5) of Regulation S-X
(contingent fees); (c) four engagements where legal and expert services were
provided to UniCredit in the Czech Republic and Germany, and twenty engagements
where the legal advisory services were provided to UniCredit in Austria, Czech
Republic, Italy and Poland, that were determined to be inconsistent with Rule
2-01(c)(4)(ix) and (x) of Regulation S-X (legal and expert services); and (d)
two engagements for UniCredit in Italy involving assistance in the sale of
certain assets, that were determined to be inconsistent with Rule
2-01(c)(4)(viii) of Regulation S-X (broker-dealer, investment adviser or
investment banking services). None of the foregoing services involved the Fund,
any of the other funds in the Pioneer Family of Funds or any other Pioneer
entity sold by UniCredit in the Transaction.

EY advised the Audit Committee that it had considered the matters described
above and had concluded that such matters would not impair EY's ability to
exercise objective and impartial judgment in connection with the audits of the
financial statements of the Funds under the SEC and Public Company Accounting
Oversight Board independence rules, and that a reasonable investor with
knowledge of all relevant facts and circumstances would reach the same
conclusion. Management and the Audit Committee considered these matters and
discussed the matters with EY and, based upon EY's description of the matters
and statements made by EY, Management and the Audit Committee believe that EY
will be capable of exercising objective and impartial judgment in connection
with the audits of the financial statements of the Fund, and Management further
believes that a reasonable investor with knowledge of all relevant facts and
circumstances would reach the same conclusion.

 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 Amudi Pioneer Asset Management, Inc, 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.
