Letter from the Chairman 10/31/98
- --------------------------------------------------------------------------------

Dear Shareowner,
- --------------------------------------------------------------------------------

I am pleased to introduce this report for Pioneer Europe Fund, covering the
fiscal year ended October 31, 1998. I thank you for your investment with
Pioneer, and I appreciate this opportunity to comment briefly on the world of
global finance and your Fund's continued success.

No single year in recent memory better illustrated both the potential rewards
and the risks that accompany international investing. The dramatic fluctuations
of global markets put investors to the test every quarter during the period.
Starting with the market dive in October of 1997 that fulfilled the correction
of the preceding summer months and ending with a resurgent bull market in the
United States and Europe in October of 1998, investors saw a little of
everything. Discipline, clear thinking and patience were required for investing
success in the past 12 months. Discipline to recall the risks inherent in any
investment when the markets were up. Clear thinking when prices were down, to
keep emotion at bay and to remember the potential rewards of investing in
well-run companies. Finally, patience to stay invested for the long term and to
understand that a single year is not a definitive time period for success or
failure.

For any individual, these are difficult tasks. For Pioneer, these difficult
tasks are the work we do everyday. Seventy years of experience, coupled with
in-depth research capabilities, gives us the knowledge to stay disciplined,
patient and thoughtful for you and your money. As the 1990's close and we enter
a new decade and a new era, these fundamental precepts of investing should
accompany all investors into the future.

I encourage you to read on and learn more about Pioneer Europe Fund. If you have
questions about your Fund, please contact your investment professional, or call
Pioneer at 1-800-225-6292.

Respectfully,

/s/John F. Cogan, Jr.

PORTFOLIO MANAGEMENT DISCUSSION 10/31/98
- --------------------------------------------------------------------------------

In recent years, European markets have become an attractive destination for
investors. Improving economic growth, corporate restructuring and the
anticipated launch of the euro in 1999 helped push stock prices higher. And even
though the meltdown of Asia's financial and currency markets became an economic
slowdown of global proportions with European companies feeling the effects, the
Fund performed solidly for the fiscal year. The following discussion with your
Fund's portfolio manager, Patrick M. Smith, explains the factors and events that
influenced his strategy and your Fund's performance over the past year.

Q: How did the Fund perform during the 12 months ended October 31?

A: The Fund got off to a strong start. European stocks rallied well into the
   second half of the year, despite ongoing concerns about Asia's economic
   malaise. In August, however, decelerating growth worldwide and ongoing
   economic turmoil in emerging markets triggered a steep decline in global
   stock prices. The markets remained skittish into September. October brought a
   partial recovery (helped by a reduction in U.S. interest rates and the
   International Monetary Fund's efforts to confront Brazil's deepening economic
   crisis).

   In this volatile market, Pioneer Europe Fund's Class A Shares returned 14.5%
   at net asset value for the year ended October 31, 1998. The average return
   for the 91 European regional funds tracked by Lipper Analytical Services was
   15.5%. The 12-month total return for the Morgan Stanley Capital International
   (MSCI) Europe Index was 23.1%. The Fund's allocations to investment
   management and capital goods companies helped the Fund early in the year, but
   held it back in later months.

Q: Why has Europe been affected by Asia's recession?

A: For more than a year, currency and economic problems have plagued the Pacific
   Rim, driving the region's economies into recession. Asian demand for European
   goods has dropped dramatically, resulting in earnings disappointments and
   fears that Europe's economic expansion may be slowing.

PORTFOLIO MANAGEMENT DISCUSSION 10/31/98 (continued)
- --------------------------------------------------------------------------------

   The inability of Asian leaders to address their deepening crisis has shaken
   investors' confidence in all emerging markets. Russia's default on its
   short-term debt and the devaluation of the ruble shocked world markets.
   Investors were quick to react, and stocks fell sharply around the globe, most
   precipitously in emerging market nations. Now, there is concern Latin America
   may be forced to devalue their currencies in the face of continued capital
   outflows and falling exports. Nervous investors remain alert to the
   vulnerability of European companies to further instability in the economies
   and businesses in emerging markets.

Q: Did you find new investment opportunities in this environment?

A: Yes. We found opportunities in telecommunications, healthcare and utility
   stocks. These investments tend to play a defensive role, generally declining
   less than the overall market in periods of uncertainty. Telecommunications is
   an area in which monopolies are coming under pressure and competition is
   increasing. MobilCom (Germany), a well-managed company that is steadily
   increasing market share, is the Fund's largest holding. The Fund has profited
   from holdings in several pharmaceutical companies, Novartis (Switzerland) and
   Roche Holdings (Switzerland). Utility investments increased with the addition
   of Aguas de Barcelona (Spain) and Suez Lyonnaise des Eaux (France), both of
   which are dedicated to delivering high-quality drinking water.

Q: What else are you doing to prepare the Fund for a changing European economy?

A: Improving news on the international front lifted investors' spirits during
   October, sparking a rebound in European markets. We took steps to reposition
   the portfolio during the rally by selling companies with weaker prospects and
   buying less cyclical, more defensive companies, which may fare better in a
   slower-growth environment.

   The capital goods industry (which manufactures products used in the
   production of other goods, such as machinery and equipment), was one of the
   most battered sectors in the recent correction. Many of these businesses are
   encountering slower global demand. Consequently, we eliminated positions in
   machine tool maker IWKA (Germany) and Philips Electronics (Netherlands) while
   reducing posi-

   tions in paper machinery company Valmet (Finland) and mining-equipment
   provider Svedala (Sweden).

   We also sold holdings in several companies that announced disappointing
   earnings. This list includes auto/bus fleet manager Arriva (U.K.), the
   pharmaceutical company Astra (Sweden), oil and gas producer Veba (Germany),
   which has controversial nuclear exposure, and Olicom (Denmark), a
   manufacturer of computer networking equipment. The potential for
   disappointing earnings led us to sell broadcaster Schibsted (Norway).

Q: How did the Fund's financial holdings fare?

A: Asset management holdings have long been a backbone of the portfolio and
   played a large role in the Fund's performance -- both during the stock
   market's rise and its correction. After a meteoric climb through March,
   financial-service stocks fell further than the general market as investors
   moved toward more conservative fixed-income and money market investments.

   We're still very optimistic about the sector's long-term potential,
   especially in light of the growing demand for pension and personal retirement
   plans. Restructuring and mergers and acquisitions should also help boost
   prices of financial services companies. Two of the Fund's positions, Amvescap
   (U.K.) and Julius Baer Holding, a top ten holding, (Switzerland), are in this
   group.

Q: What is your outlook for the new fiscal year?

A: European stocks have generated some very rewarding performance in recent
   memory. But markets move in cycles, and investing overseas carries certain
   risks, including currency fluctuations and political and economic
   uncertainty.

   The recent fluctuations in stock prices are disconcerting and distracting.
   But stock investing requires a long-term vision, and there are many positive
   economic and demographic trends in place throughout Europe that bode well for
   its stock markets over time. We believe Pioneer Europe Fund's emphasis on
   innovative, fast-growing companies will serve investors well in the coming
   months and beyond.

1. Organization and Significant Accounting Policies

Pioneer Europe Fund (the Fund) is a Massachusetts business trust registered
under the Investment Company Act of 1940 as a diversified, open-end management
investment company. The investment objective of the Fund is to seek long-term
growth of capital.

The Fund offers four classes of shares - Class A, Class B, Class C, and Class Y
shares. Class Y shares were first publicly offered on July 2, 1998. Each class
of shares represents an interest in the same portfolio of investments of the
Fund and have equal rights to voting, redemptions, dividends and liquidation,
except that the level of transfer agent and distribution fees may differ among
classes. Class A, Class B and Class C shareholders have exclusive voting rights
with respect to the distribution plan for each class. There is no distribution
plan for Class Y shares.

The Fund's financial statements have been prepared in conformity with 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 revenues and
expenses during the reporting periods. Actual results could differ from those
estimates. The following is a summary of significant accounting policies
consistently followed by the Fund, which are in conformity with those generally
accepted in the investment company industry:

A. Security Valuation

   Security transactions are recorded on trade date. The net asset value is
   computed once daily, on each day the New York Stock Exchange is open, as of
   the close of regular trading on the Exchange. In computing the net asset
   value, securities are valued at the last sale price on the principal exchange
   where they are traded. Securities that have not traded on the date of
   valuation, or securities for which sale prices are not generally reported,
   are valued at the mean between the last bid and asked prices. Securities for
   which market quotations are not readily available are valued at their fair
   values as determined by, or under


                                                                              25

   the direction of, the Board of Trustees. Trading in foreign securities is
   substantially completed each day at various times prior to the close of the
   New York Stock Exchange. The values of such securities used in computing the
   net asset value of the Fund's shares are determined as of such times.
   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 is informed of the ex-dividend data in the
   exercise of reasonable diligence. Interest income is recorded on the accrual
   basis, net of unrecoverable foreign taxes withheld at the applicable country
   rates. Temporary cash investments are valued at amortized cost.

   Gains and losses on sales of investments are calculated on the identified
   cost method for both financial reporting and federal income tax purposes. It
   is the Fund's practice to first select for sale those securities that have
   the highest cost and also qualify for long-term capital gain or loss
   treatment for tax purposes.

B. 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 represent,
   among other things, the net realized gains and losses on foreign currency
   contracts, disposition of foreign currencies and the difference between the
   amount of income accrued and the U.S. dollar actually received. Further, the
   effects of changes in foreign currency exchange rates on investments are not
   segregated in the statement of operations from the effects of changes in
   market price of those securities but are included with the net realized and
   unrealized gain or loss on investments.

C. Forward Foreign Currency Contracts

   The Fund enters into forward foreign currency contracts (contracts) for the
   purchase or sale of a specific foreign currency at a fixed price on a future
   date as a hedge or cross-hedge against either specific invest-


26
<PAGE>

Pioneer Europe Fund

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

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

   ment transactions (settlement hedges) or portfolio positions (portfolio
   hedges). All contracts are marked to market daily at the applicable exchange
   rates, and any resulting unrealized gains or losses are recorded in the
   Fund's financial statements. The Fund records realized gains and losses at
   the time a portfolio hedge is offset by entry into a closing transaction or
   extinguished by delivery of the currency. Risks may arise upon entering into
   these contracts from the potential inability of counterparties to meet the
   terms of the contract and from unanticipated movements in the value of
   foreign currencies relative to the U.S. dollar.

   As of October 31, 1998, the Fund had no outstanding portfolio hedges. The
   Fund's gross forward foreign currency settlement contracts receivable and
   payable were $25,037,177 and $25,036,103, respectively, resulting in a net
   receivable of $1,074 as of October 31, 1998.

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 taxable income and net realized capital gains, if any, to its
   shareholders. Therefore, no federal income tax provision is required.

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

   At October 31, 1998, the Fund has reclassified $46,185 from accumulated
   undistributed net investment income to accumulated undistributed net realized
   gain on investments and foreign currency transactions. The reclassification
   has no impact on the net asset value of the Fund and is designed to present
   the Fund's capital accounts on a tax basis.


                                                                              27

NOTES TO FINANCIAL STATEMENTS 10/31/98                               (continued)
- --------------------------------------------------------------------------------

   In order to comply with federal income tax regulations, the Fund has
   designated $12,772,834 as a capital gain dividend for the purposes of the
   dividend paid deduction.

E. Fund Shares

   The Fund records sales and repurchases of its shares on trade date. Net
   losses, if any, as a result of cancellations are absorbed by Pioneer Funds
   Distributor, Inc. (PFD), the principal underwriter for the Fund and an
   indirect subsidiary of The Pioneer Group, Inc. (PGI). PFD earned $365,139 in
   underwriting commissions on the sale of fund shares during the year ended
   October 31, 1998.

F. Class Allocations

   Distribution fees are calculated based on the average daily net asset value
   attributable to Class A, Class B and Class C shares of the Fund,
   respectively. Class Y shares are not subject to a distribution plan.
   Shareholders of each class share all expenses and fees paid to the transfer
   agent, Pioneering Services Corporation (PSC), for their services, which are
   allocated based on the number of accounts in each class and the ratable
   allocation of related out-of-pocket expense (see Note 3).

   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 the respective percentage of adjusted net assets at the beginning of
   the day.

   Distributions to shareholders 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, at the same time, and in the same amount,
   except that Class A, Class B, Class C, and Class Y shares can bear different
   transfer agent and distribution fees.

2. Management Agreement

Pioneer Investment Management, Inc. (PIM), the Fund's investment adviser,
manages the Fund's portfolio and is a wholly owned subsidiary of PGI.


28
<PAGE>

Pioneer Europe Fund

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

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

Management fees are calculated daily at the annual rate of 1.00% of the Fund's
average daily net assets up to $300 million; 0.85% of the next $200 million; and
0.75% of the excess over $500 million.

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. At October 31, 1998, $486,647 was payable to PIM
related to management fees and administrative services.

3. Transfer Agent

PSC, a wholly owned subsidiary of PGI, provides substantially all transfer agent
and  shareholder  services to the Fund at negotiated  rates.  Included in due to
affiliates is $58,059 in transfer agent fees payable to PSC at October 31, 1998.

4. Distribution Plans

The Fund  adopted  Plans of  Distribution  with respect to Class A, Class B, and
Class C shares (Class A Plan,  Class B Plan and Class C Plan) in accordance with
Rule 12b-1 of the Investment Company Act of 1940.  Pursuant to the Class A Plan,
the Fund pays PFD a service fee of up to 0.25% of the Fund's  average  daily net
assets  in  reimbursement  of its  actual  expenditures  to  finance  activities
primarily  intended  to result in the sale of Class A  shares.  Pursuant  to the
Class B Plan and the Class C Plan,  the Fund pays PFD 1.00% of the average daily
net assets  attributable  to each class of shares.  The fee  consists of a 0.25%
service  fee and a 0.75%  distribution  fee paid as  compensation  for  personal
services  and/or  account  maintenance  services or  distribution  services with
regard to Class B and Class C shares.  Included in due to affiliates is $191,493
in distribution fees payable to PFD at October 31, 1998.

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 one year of purchase.  Class B shares 


                                                                              29

that are redeemed within six years of purchase are subject to a CDSC at
declining rates beginning at 4.0%, based on the lower of cost or market value of
shares being redeemed. Redemptions of Class C shares within one year of purchase
are subject to a CDSC of 1.00%. Proceeds from the CDSCs are paid to PFD. For the
year ended October 31, 1998, CDSCs in the amount of $202,834 were paid to PFD.

5. Expense Offsets

The Fund has entered into certain expense offset arrangements resulting in a
reduction in the Fund's total expenses. For the year ended October 31, 1998, the
Fund's expenses were reduced by $163,330 under such arrangements.

6. Line of Credit Facility

Effective April 14, 1998, the Fund, along with certain other Funds in the
Pioneer Family of Funds (the Funds), collectively participate in a $50 million
committed, unsecured revolving line of credit facility. Borrowings are used
solely for temporary or emergency purposes. The Fund may borrow up to the lesser
of $50 million or the limits set by its prospectus for borrowings. Interest on
collective borrowings of up to $25 million is payable at the Federal Funds Rate
plus 3/8% on an annualized basis, or at the Federal Funds Rate plus 1/2% if the
borrowing exceeds $25 million at any one time. The Funds pay an annual
commitment fee for this facility. The commitment fee is allocated among such
Funds based on their respective borrowing limits. For the period ended October
31, 1998, the Fund had no borrowings under this agreement.

7. Affiliated Companies

The Fund's investments in certain companies exceed 5% of the outstanding voting
stock. Such companies are deemed affiliates of the Fund for financial reporting
purposes. The following summarizes transactions with affiliates of the Fund as
of October 31, 1998:

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

A SALUTE TO PIONEER FUND
- --------------------------------------------------------------------------------

                               HAPPY 70th BIRTHDAY
                                  PIONEER FUND
                                     [LOGO]

This year, 1998, marks a special anniversary for the Pioneer family of mutual
funds and an important milestone for the entire mutual fund industry. In the
1920s, a group of forward thinking financial professionals started the first
"open-end" investment companies, known today as mutual funds. They provided a
way for small investors to benefit from professional financial management.

In 1928, Pioneer Fund became the fourth mutual fund created.

Pioneer Fund has gone to work for its shareowners everyday for 70 years. Through
15 bear markets, 16 bull markets and even the Great Depression, Pioneer Fund has
stayed true to an investment ethic that relies on the rewards of hard work.

Rather than follow trends, the financial professionals at Pioneer roll-up their
sleeves and research. We look for value in an investment: companies that might
not be the current rage on Wall Street, but that we believe have the business
smarts on Main Street to keep their earnings strong. The Fund's investment
objective continues to be growth and income.

For 70 years, Pioneer Fund has made investments based on experience, our own
investment ethic, and the needs of our shareowners.

Every day, the financial professionals at Pioneer Fund come to work, aware of
the job at hand. We know shareowners are investing their hard-earned money to
provide for the future.

In 1928 there were four mutual funds. Today there are 11,000. Only one can tell
the Pioneer Fund story.

For the complete Pioneer Fund story call your investment professional, or
Pioneer at 1-800-225-6292, for a prospectus. Please read it carefully before you
invest or send money.

Class B and C Shares have been available since 7/1/96. Past performance does not
guarantee future results.


                                                                              33

items directly, simply call Pioneer at 1-8O0-225-6292.

redemption. You have the choice of investing in any Pioneer fund, as long as you
meet its minimum investment requirement.

Investomatic Plan

An easy and convenient way for you to invest on a regular basis. All you need to
do is authorize a set amount of money to be moved out of your bank account into
the Pioneer fund of your choice. Investomatic also allows you to change the
dollar amount, frequency and investment date right over the phone. By putting
aside affordable amounts of money regularly, you can build a long-term
investment without sacrificing your current standard of living.

Payroll Investment Program (PIP)

to deduct from participating employees' paychecks. You specify the dollar amount
you want to invest into the Pioneer fund(s) of your choice.

Automatic Exchange Program

A simple way to move money from one Pioneer fund to another over a period of
time. Just invest a lump sum in one fund, and select the other Pioneer funds you
wish to invest in. You choose the amounts and dates for Pioneer to sell shares
of your original fund and use the proceeds to buy shares of the other funds you
have chosen. Over time, your investment will be shifted out of the original
fund. (Automatic Exchange is available for originating accounts with a balance
of $5,000 or more.)

Directed Dividends

Lets you invest cash dividends from one Pioneer fund to an account in another
Pioneer fund with no sales charge or fee. Simply fill out the applicable
information on a Pioneer Account Options Form. (This program is available for
dividend payments only; capital gains distributions are not eligible at this
time.)

Direct Deposit

Lets you move money into your bank account using electronic funds transfer
(EFT). EFT moves your money faster than you would receive a check, eliminates
unnecessary paper and mail, and avoids lost checks. Simply fill out a Pioneer
Direct Deposit Form, giving your instructions.

Systematic Withdrawal Plan (SWP)

Lets you establish automatic withdrawals from your account at set intervals. You
decide the frequency and the day of the month you want. Pioneer will send the
proceeds by check to the address you designate, or electronically to your bank
account. You also can authorize Pioneer to make the redemptions payable to
someone else. (SWPs are available only for accounts with a value of $10,000 or
more.)
