Thomas J. Fetter, President

Eaton Vance Municipal Bond Fund, L.P. had a total return of 14.1% for the year 
ended December 31, 1997. That return was the result of a rise in net asset value
per share from $10.07 on December 31, 1996 to $10.84 on December 31, 1997, and 
the reinvestment of $0.5985 in dividends. Based on its one-year performance, the
Fund was ranked first among General Municipal Debt Funds as compiled by Lipper 
Analytical Services, Inc. -- a nationally recognized monitor of mutual fund 
performance. The average return for the group was 9.1% for the same period./1/

Investors were drawn to municipal bonds in a volatile period for the world's 
fixed-income markets...

1997 was a very good year for municipal bonds. Against a backdrop of moderate 
economic growth and low inflation, investors focused once again on the 
advantages of municipals, which remain among the best tax-advantaged investment 
vehicles. In addition, the municipal market attracted an increasing number of 
crossover investors from other markets. Many investors bought municipals in a 
flight to quality as the domestic equity market reached overvalued levels and 
emerging markets were caught up in the turmoil of the Asian currency crisis.

1998 should bring more opportunities for municipal investors...

The upbeat economic climate has provided strong support for the municipal 
market. Steady job growth has generated increased tax revenue for states and 
local issuers. As a result, many areas that were hard-hit in the recessions of 
the 1970s and 1980s have since made a significant economic comeback. Their 
recovery has been reflected in the value of their bonds, which have in turn 
financed worthwhile public projects such as bridges, roads and industrial 
development. We expect to see many more such opportunities emerge in the coming 
year.

The Fund's performance again earned high marks from Morningstar...

The Fund's risk-adjusted performance through December 31 earned it a Five-Star 
Overall rating among municipal bond funds covered by Morningstar, Inc./2/ -- a 
nationally recognized monitor of mutual fund performance. We will continue to 
focus on promising opportunities within the municipal market in the coming year.

                                      Sincerely,


                                      /s/ Thomas J. Fetter

Thomas J. Fetter
Portfolio Manager

An interview with Thomas J. Fetter, president and portfolio manager of Eaton
Vance Municipal Bond Fund.

Q:  Tom how would you characterize the municipal bond market in 1977?

A:  The climate was favorable for the bond market in general, as inflation
    become less of a force in the economy. While the Federal Reserve has done an
    excellent job of monitoring inflation, the increasingly global nature of the
    economy has restrained the wage and price pressures seen in past cycles.

    The municipal market performed very well, although it did slightly lag the
    Treasury market. The primary reason for the underperformance was a rise in
    municipal supply. According to the Bond Market Association, long-term
    municipal issuance rose to more than $220 billion in 1997, up from around
    $190 billion in the previous year.

Q:  The Fund had an excellent year. What accounted for the Fund's performance?

A:  Given our favorable outlook for inflation, we maintained a relatively long
    average maturity. That structure increased the Fund's sensitivity to falling
    interest rates. In addition, the Fund was well positioned from a sector
    standpoint to participate fully in the rally. The Fund's largest sector
    weightings at December 31, were transportation bonds, long-term care issues,
    escrowed bonds, and insured bonds.

Q:  Could we look at those sectors in greater detail?

A:  Transportation in an area of the economy that has attracted an increasing
    amount of public investment in recent years. States and localities have
    invested large sums to upgrade roads, bridges, and airports. In addition,
    many jurisdictions have restructured existing systems to better meet the
    needs of the next century.

    One such issuer, the Massachusetts Turnpike Authority, was the Fund's
    largest holding at December 31. As operator of the Commonwealth's largest
    toll road, the Authority initiated a revamping of its toll structure,
    funneling

   toll proceeds toward users in specific areas, such as the Metro/Boston
   region. The restructuring allowed the authority to raise massive funds to
   help finance Boston's Central Artery/Third Harbor Tunnel project. As a result
   of the restructuring, the Authority's bonds were upgraded from A to AAA. In
   addition, the bonds went from callable to non-callable status. Each of those
   developments contributed to a significant price appreciation for the Fund's
   investment.

Q: Long-term care issues were your second largest investment. What did you find 
   attractive about that sector?

A: The health care sector has become increasingly competitive in recent years as
   institutions struggle to maintain market share while providing quality care.
   As a result of that competition, there will be clear winners, while less
   competitive institutions are likely to fail.

   Long-term life care facilities represent one health care niche that is
   gaining market share and becoming increasingly vital for a fast-aging
   population. These projects provide a wide range of services to meet the
   housing, nursing, health care and social needs of our senior citizens.
   Facilities such as New Jersey's Keswick Pines Project allow independent
   living, while offering help with day-to-day needs and health care services as
   residents require them. Equally as important, they have been found to be a
   cost-effective health care alternative. We have uncovered compelling values
   in some of these bonds, which are typically smaller, non-rated issues that
   require very intensive research.

Q: Another major focus was escrowed bonds. What drew you to that sector?

A: Escrowed bonds are those that have been pre-refunded by their issuers as part
   of an effort to take advantage of a lower interest rate environment. It's not
   unlike homeowners refinancing their mortgages to get a better interest rate.
   Escrowed bonds are backed by U.S. Treasury bonds and are therefore viewed as
   the very highest quality. In the 1997 bond rally, when investors engaged in a
   flight to quality, the Fund was especially well-served by its Treasury-backed
   escrowed bonds.

Q: Earlier, you mentioned non-rated bonds. Have non-rated bonds played a large 
   role in your strategy?

A: Yes. We've taken advantage of our municipal credit research strengths and
   been able to find good value in non-rated bonds. In a market where new
   issuance is increasingly dominated by insured bonds, the non-rated segment
   offers some compelling opportunities. I mentioned the continuing life care
   sector earlier, but we have also found non-rated bonds in the nursing home,
   transportation, and housing areas.

   Typically, non-rated bonds offer an attractive yield advantage over their
   rated counterparts. But we apply the same rigorous standards to this segment
   of the market as to rated bonds. At Eaton Vance, we have made a major
   commitment to credit research. We have analysts dedicated to industry sectors
   within the municipal market, thereby assuring us of the continuing coverage
   that is needed to monitor these bonds effectively.

Q: What is your outlook for the municipal market in the coming year?

A: Generally, the outlook for the market is favorable. There is little sign of
   inflation on the horizon, and, with the Asian turmoil of recent months, it's
   possible that the economy may slow somewhat in the next year. Furthermore,
   the federal budget situation has improved dramatically in the past several
   years. That also improves the outlook for bonds.

I'd caution, however, that conditions could change over time. The market could
be vulnerable if the economy strengthens or the budget situation unexpectedly
worsens. We will, naturally, continue to closely monitor the economy for
developments that might alter the outlook.

Meanwhile, the Bond Market Association has estimated that issuance of new
municipal bonds will decline slightly in 1998. Thus, investor demand should be
more than adequate to absorb new municipal supply. In that kind of environment,
the municipal market should fair well.

Moreover, investors should consider municipals as a way to balance their
portfolios. It's a useful exercise to review one's investment allocations from
time to time, especially in the wake of the returns in recent years from
equities. 1997 marked the third consecutive year that the stock market returned
more than 20%, an unprecedented run for the equity market. It's reasonable,
therefore, to assume that at some point the equity averages may revert to their
historical annual returns -- closer to 10%.

A portfolio that includes municipal bonds offers the advantage of
diversification as well as high after-tax income. Those are important
considerations for investors. I'm confident that municipal bonds will continue
to serve their traditional function of financing vital public works while
offering good investment opportunities to tax-conscious citizens.

The Fund invests primarily in debt securities issued by municipalities. The
ability of the issuers of the debt securities to meet their obligations may be
affected by economic developments in a specific industry or municipality. In
order to reduce the risk associated with such economic developments, at December
31, 1997, 18.0% of the securities in the portfolio of investments are backed by
bond insurance of various financial institutions and financial guaranty
insurance agencies. The aggregate percentage by financial institution range from
2.6% to 6.3% of total investments. 

/(1)/ Security has been segregated to cover when-issued securities. 

/(2)/ Security has been issued as an inverse floater bond.

/(3)/ When-issued security.

/(1)/ Total return is calculated assuming a purchase at the net asset value on
      the first day and a sale at the net asset value on the last day of each
      period reported. Dividends and distributions, if any, are assumed to be
      reinvested at the net asset value on the payable date. Total return is not
      computed on an annualized basis.
/(2)/ The expense ratios for the year ended December 31, 1995 and periods
      thereafter have been adjusted to reflect a change in reporting
      requirements. The new reporting guidelines require the Fund to increase
      its expense ratio by the effect of any expense offset arrangements with
      its service providers. The expense ratios for the periods ended on or
      before December 31, 1994 have not been adjusted to reflect this change.

Eaton Vance Municipal Bond Fund, L.P. as of December 31, 1997

NOTES TO FINANCIAL STATEMENTS 


1 Significant Accounting Policies
  ------------------------------------------------------------------------------
  Eaton Vance Municipal Bond Fund, L.P. (the Fund) is a limited partnership
  formed under the laws of the State of California, and is registered under the
  Investment Company Act of 1940, as amended, as a diversified, open-end
  management investment company. Under the Partnership Agreement, all
  partnership interests, whether of a limited partner or a general partner, are
  represented by shares of the same class. The following is a summary of
  significant accounting policies consistently followed by the Fund in the
  preparation of its financial statements. The policies are in conformity with
  generally accepted accounting principles.

  On December 12, 1997, at a Special Meeting of the Partners of the Fund, the
  Partners approved a Plan of Reorganization (the Plan) for the Fund. Under the
  terms of the Plan, the Fund will transfer substantially all of its assets and
  liabilities to the Eaton Vance Municipal Bond Fund (the Successor Fund, one of
  the series of Eaton Vance Mutual Funds Trust). The transaction will be
  structured for tax purposes as a tax free reorganization under the Internal
  Revenue Code. As a result of the reorganization, all partners of the Fund will
  receive shares of beneficial interest of the Successor Fund designated as
  Class I shares equal to the number of shares of partnership interest of the
  Fund then outstanding. The reorganization will occur after the close of
  business, December 31, 1997.

  A Investment Valuations -- Municipal bonds are normally valued on the basis of
  valuations furnished by a pricing service. Taxable obligations, if any, for
  which price quotations are readily available are normally valued at the mean
  between the latest available bid and asked prices. Futures contracts and
  options on financial futures contracts listed on commodity exchanges are
  valued at closing settlement prices. Over-the-counter options on financial
  futures are normally valued at the mean between the latest bid and asked
  prices. Investments, if any for which there are no such valuations are valued
  at fair value using methods determined in good faith by or at the direction of
  the Director General Partners. Short-term obligations, maturing in sixty days
  or less, are valued at amortized cost, which approximates value.

  B Income -- Interest income is determined on the basis of interest accrued and
  discount earned, adjusted for amortization of premium or discount on long-term
  debt securities when required for federal income tax purposes.

  C Income Taxes -- Interest income received by the Fund on investments in
  municipal bonds, which is excludable from gross income under the Internal
  Revenue Code, will retain its status as income exempt from federal income tax
  when allocated to the Fund's partners. The portion of such interest, if any,
  earned on private activity bonds issued after August 7, 1986, may be
  considered a tax preference item for shareholders. No provision is made by the
  Fund for federal or state taxes on any taxable income of the partnership
  because each partner is individually responsible for the payment of any taxes
  on his share of such taxable income.

  D Financial Futures Contracts -- Upon the entering of a financial futures
  contract, the Fund is required to deposit ("initial margin") either in cash or
  securities an amount equal to a certain percentage of the purchase price
  indicated in the financial futures contract. Subsequent payments are made or
  received by the Fund ("margin maintenance") each day, dependent on the daily
  fluctuations in the value of the underlying security, and are recorded for
  book purposes as unrealized gains or losses by the Fund. The Fund's investment
  in financial futures contracts is designed only to hedge against anticipated
  future changes in interest rates. Should interest rates move unexpectedly, the
  Fund may not achieve the anticipated benefits of the financial futures
  contracts and may realize a loss.

  E Put Options on Financial Futures Contracts -- Upon the purchase of a put
  option on a financial futures contract by the Fund, the premium paid is
  recorded as an investment, the value of which is marked-to-market daily. When
  a purchased option expires, the Fund will realize a loss in the amount of the
  cost of the option. When the Fund enters into a closing sale transaction, the
  Fund will realize a gain or loss depending on whether the sales proceeds from
  the closing sale transaction are greater or less than the cost of the option.
  When the Fund exercises a put option, settlement is made in cash. The risk
  associated with purchasing options is limited to the premium originally paid.

  F When-issued and Delayed Delivery Transactions -- The Fund may engage in 
  when-issued or delayed delivery transactions. The Fund records when-issued
  securities on trade date and maintains security positions such that sufficient
  liquid assets will be available to make payment for the securities purchased.
  Securities purchased on a when-issued or delayed delivery basis are marked-to-
  market daily and begin accruing interest on settlement date.

NOTES TO FINANCIAL STATEMENTS CONT'D

 
  G Other -- Investment transactions are accounted for on a trade date basis.
  Distributions to partners and shares of partnership interest issued in
  payment thereof are recorded on the ex-date.

  H Expense Reduction -- Investors Bank & Trust Company (IBT) serves as
  custodian of the Fund. Pursuant to the custodian agreement, IBT receives a
  fee reduced by credits which are determined based on the average daily cash
  balances the Fund maintains with IBT. All significant credit balances used to
  reduce the Fund's custodian fees are reported as a reduction of expenses in
  the Statement of Operations.

  I Use of Estimates -- The preparation of financial statements in conformity
  with generally accepted accounting principles requires management to make
  estimates and assumptions that affect the reported amounts of assets and
  liabilities at the date of the financial statements and the reported amounts
  of revenue and expense during the reporting period. Actual results could
  differ from those amounts.

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


3 Purchases and Sales of Investments
  ------------------------------------------------------------------------------
  The Fund invests primarily in debt securities. The ability of the issuers of
  the debt securities held by the Fund to meet their obligations may be affected
  by economic developments in a specific industry or municipality. Purchases and
  sales of investments, other than short-term obligations and put option
  transactions, aggregated $30,501,417 and $34,074,953, respectively.

4 Investment Adviser Fee and Other Transactions with Affiliates
  ------------------------------------------------------------------------------
  The investment adviser fee, computed at the monthly rate of 0.025% (0.300% per
  annum) of the average daily net assets and 3.00% of gross income (excluding
  net realized gains on sales of securities) up to $500 million and at reduced
  rates as daily net assets exceed that level, was earned by Eaton Vance
  Management (EVM), the Adviser General Partner, as compensation for management
  and investment advisory services rendered to the Fund. For the year ended
  December 31, 1997, the fee was equivalent to 0.49% of the Fund's average daily
  net assets for such period and amounted to $441,330. Except as to Director
  General Partners who are not members of EVM's organization, officers and
  Director General Partners receive remuneration for their services to the Fund
  out of such investment adviser fee. Eaton Vance Distributors, Inc., a
  subsidiary of EVM and the Fund's principal underwriter, received $3,205 as its
  portion of the sales charge on sales of partnership interest in the Fund.
  Certain of the Director General Partners of the Fund are directors/trustees
  and/or officers of the above organizations. Director General Partners of the
  Fund that are not affiliated with the Investment Adviser may elect to defer
  receipt of all or a portion of their annual fees in accordance with the terms
  of the Trustees Deferred Compensation Plan. For the year ended December 31,
  1997, no significant amounts have been deferred.

5 Line of Credit
  ------------------------------------------------------------------------------
  The Fund participates with other portfolios and funds managed by EVM and
  affiliates in a $100 million unsecured line of credit with a group of banks.
  Borrowings will be made by the Fund solely to facilitate the handling of
  unusual and/or unanticipated short-term cash requirements. Interest is charged
  to each participating portfolio or fund based on its borrowings at an amount
  above either the Eurodollar rate or federal funds rate. In addition, a fee
  computed at an annual rate of 0.10% on the daily unused portion of the line of
  credit is allocated among the participating portfolios and funds at the end of
  each quarter. At December 31, 1997, the Fund had a balance outstanding
  pursuant to the line of credit of $1,352,000.

6 Federal Income Tax Basis of Investments
  ------------------------------------------------------------------------------
  The cost and unrealized appreciation/depreciation in value of the investments
  owned at December 31, 1997, as computed on a federal income tax basis, were as
  follows:

  Aggregate cost                           $81,428,061
  ----------------------------------------------------
  Gross unrealized appreciation            $11,950,946

  Gross unrealized depreciation                     --
  ----------------------------------------------------
  Net unrealized appreciation              $11,950,946
  ----------------------------------------------------  


7 Financial Instruments
  ------------------------------------------------------------------------------
  The Fund regularly trades in financial instruments with off-balance sheet risk
  in the normal course of its investing activities to assist in managing
  exposure to various market risks. These financial instruments include futures
  contracts and may involve, to a varying degree, elements of risk in excess of
  the amounts recognized for financial statement purposes. The notional or
  contractual amounts of these instruments represent the investment the Fund has
  in particular classes of financial instruments and does not necessarily
  represent the amounts potentially subject to risk. The measurement of the
  risks associated with these instruments is meaningful only when all related
  and offsetting transactions are considered. There were no open obligations
  under these financial instruments at December 31, 1997.

INDEPENDENT AUDITORS' REPORT




To the Partners of

We have audited the accompanying statement of assets and liabilities, including

ended, the statements of changes in net assets for the years ended December 31,
1997 and 1996 and the financial highlights for each of the years in the
five-year period ended December 31, 1997. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. 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. An audit includes examining, on a

statements. Our procedures included confirmation of securities held as of
December 31, 1997 by correspondence with the custodian and brokers; where
replies were not received from brokers, we performed other audit procedures. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion. 

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of Eaton Vance
Municipal Bond Fund, L.P. as of December 31, 1997, the results of its
operations, the changes in its net assets and its financial highlights for the
