As personal wealth continues to grow at an ever-increasing rate, people are
realizing the power of their investments to do good and to make a difference in
their families and communities now and for generations to come.

Setting financial goals is an important first step toward building wealth. At
Nuveen Investments, we believe those goals should not be considered ends in
themselves. Rather, you and your financial advisor's focus should be on
realizing your life's dreams -- the things that matter most to you and how you
can make them happen -- or make them better.


Through a well-crafted financial plan, you have the chance to shape future
generations -- to broaden your sphere of influence -- to leave your legacy.


As you develop that plan, you'll want to consider the different ways your
success can benefit others. You may find that you want to create a new set of
goals to achieve this. Working with your financial advisor, you have the ability
to make those dreams a reality -- for yourself and future generations.

Family Wealth Management  Too often, family wealth management is thought of in
one dimension -- as the stewardship of your household's financial resources. At
Nuveen Investments, we think of family wealth management as the map to help you
reach your financial, and your life's, destinations. It's a multi-faceted
strategy to plan for not just your needs, but the needs of future generations.

     We are dedicated to helping you and your financial advisor develop a family
wealth management strategy unique to you and your goals and values.

A Trusted Resource  As you face some of the most important, lasting decisions
you and your family will make, you'll want to draw upon the support, counsel and
objectivity of a trusted advisor. That's because your financial advisor has the
expertise and access to other professionals who can help you make informed
choices -- choices that affect not only your loved ones today, but those your
legacy will touch in the future.

     Your financial advisor can provide sound financial insight, an integrated
approach to your investments and can serve as a knowledgeable friend with your
family's best interests at heart.

     In addition, we believe the potential presence of inflation and price
swings in the markets reinforce the importance of working with an advisor,
staying focused on the long term and adhering to your financial plan. With a
sound plan in place, you may be better positioned to weather the markets' ups
and downs.

     In fact, you may be reading this report at the suggestion of your financial
advisor. We've prepared the following interview to let you know what the
investment and research management teams have done during your fund's fiscal
period.

     For more information on any Nuveen investment, including a prospectus,
contact your financial advisor. Or call Nuveen at (800) 621-7227 or visit our
Internet site at www.nuveen.com. Please read the prospectus carefully before you
invest or send money.

     Since 1898, Nuveen has been synonymous with investments that stand the test
of time. We are committed to maintaining that reputation and working with
financial advisors to provide investment solutions that help individuals achieve
their lives dreams. Thank you for your continued confidence.

Sincerely,

NUVEEN INTERMEDIATE DURATION MUNICIPAL BOND FUND
NUVEEN INSURED MUNICIPAL BOND FUND

From the Portfolio Managers' Perspective

A rising interest rate backdrop muted municipal bond returns during the 12
months ended April 30, 2000. Tom Spalding, portfolio manager of Nuveen
Intermediate Duration Municipal Bond Fund and Steve Krupa, portfolio manager of
Nuveen Insured Municipal Bond Fund, discuss the economic environment in which
the funds participated, as well as their funds' performance and key investment
strategies.

Q  What factors determined the municipal bond market's performance during the
12-month fiscal period ended April 30, 2000?

Tom  Persistent inflation worries and rising interest rates put pressure on
nearly all bonds, including municipal securities. The Federal Reserve Board
(the Fed) raised short-term interest rates five times over the past year by a
total of 125 basis points (1.25 percentage points) in an attempt to curb
economic growth and stifle inflationary pressures. Bond yields moved higher in
response to climbing rates, and bond prices -- which move opposite their yields
-- generally declined. (The Fed raised short-term interest rates a sixth time
after the fund's fiscal year ended -- bringing the short-term interest rate to
6.50%.)

Steve  Rising interest rates had a mixed effect on municipal bond supply and
demand, which also was a key determinant in municipal bond performance. Supply
dwindled as fewer municipal issuers found it economically advantageous to
refinance older debt as interest rates rose.

     In addition, many municipal issuers enjoyed budget surpluses thanks to the
overall strength of national, regional and local economies. As a result of their
diminished need for financing, many issuers cut back on issuing new debt.

     Demand, unfortunately, remained rather spotty throughout the year.
Initially, investors gravitated to the red-hot stock market, generally avoiding
fixed income securities in the process.

     When the stock market cooled in the early months of 2000 and municipal bond
yields rose to 6%, demand for municipals was stronger. The municipal bond
market performed better in the first quarter due to increased demand from
individual investors who wished to balance their portfolios with more fixed
income investments.


Performance figures are quoted for Class A shares at net asset value. Comments
cover the fiscal 12-month period ended April 30, 2000. The views expressed
reflect those of the portfolio management team and are subject to change at any
time, based on market and other conditions.

<PAGE>

Q  How did Nuveen Intermediate Duration Municipal Bond Fund perform?

TOM  For the 12-month period ended April 30, 2000, the total return for Class A
shares at net asset value was -2.02%. The fund outperformed the Lipper General
Municipal Debt category, which returned -3.31%, but underperformed the Lehman
Brothers Municipal Bond Index, which returned 0.92%.*
     Shareholders in the 31% federal income tax bracket would have had to earn a
total return of 0.14% on a taxable investment to have earned the equivalent of
their fund's tax-exempt total return for the one-year period.
     As of April 30, 2000, the fund's SEC 30-day yield was 4.91%. For investors
in the 31% federal income tax bracket, that is equivalent to a yield of 7.12% on
a taxable investment.

Q  What key strategies did you and your team use in managing the fund during the
year?

TOM  Maintaining a competitive distribution yield was a key focus for us. In an
effort to achieve that goal, we remained fully invested in intermediate- and
long-term bonds. They generally offered higher yields than shorter-term
securities and helped the fund optimize its tax-exempt dividend.
      Rising market interest rates and bond yields also presented us with some
attractive opportunities to trade older, lower-coupon bonds for current, high-
coupon bonds. A good example of this type of opportunity occurred when we sold
some bonds issued by New York City and replaced them with bonds issued by
Illinois Health.
      In making those and other trades, we looked for opportunities to improve
the fund's call protection. That provides a measure of protection against
having to surrender a high-yielding bond to the issuer before maturity.
      We also continued to focus on higher quality bonds, holding roughly 79% of
the portfolio in AAA/U.S. guaranteed or AA-rated bonds.

Q  Which bonds performed well during the past year? Which holdings were
disappointments?

Tom  Bonds that were refunded or bought back by their issuers performed
particularly well. Recently, for example, we sold back our holdings in bonds
issued by the Intermountain Power Agency at a significant premium over market
prices. We invested the proceeds from the sale into bonds that had lower
duration--or reduced interest-rate sensitivity--and had yields that were
higher than those sold.

     Healthcare bonds, on the other hand, were disappointing throughout most of
the past 12 months. Reduced Medicare payments and heightened competition
weighed heavily on hospitals and other healthcare facilities. We take a very
selective approach, concentrating on those hospitals that we believe can thrive
in response to increased competition.


Q  Turning to you, Steve, how did Nuveen Insured Municipal Bond Fund perform
during this fiscal period?

STEVE  For the 12-month period ended April 30, 2000, the total return for Class
A shares at net asset value was -2.19%. The fund outperformed the Lipper
General Municipal Debt category, which returned -3.12%, but underperformed the
Lehman Brothers Insured Municipal Bond Index, which returned -1.65%.**
     Shareholders in the 31% federal income tax bracket would have had to earn
a total return of 0.04% on a taxable investment to have earned the equivalent
of their fund's tax-exempt total return for the 12-month period.
     As of April 30, 2000, the fund's SEC 30-day yield was 4.74%. For investors
in the 31% federal income tax bracket, that is equivalent to a yield of 6.87% on
a taxable investment.

Q  To what do you attribute the fund's performance and what were your key
strategies?

STEVE  Through our active management discipline, we took advantage of
opportunities that rising interest rates and higher bond yields afforded us. For
example, we added value by executing tax loss swaps, selling bonds at a loss in
order to buy higher-yielding bonds. As rates rose, prices on some of the fund's
holdings fell. When we sold several of the fund's holdings, tax losses were
incurred.
     These tax loss trades had two benefits for the fund. First, the
realized tax loss can be used to offset realized capital gains for up to eight
years. Furthermore, they helped increase tax-exempt income to the fund. In one
such swap in the first quarter of 2000, we sold New York City Water bonds and
captured a tax loss and then bought New York City Urban Development Corporation
bonds, which provided additional tax-free income.

<PAGE>

Q  Where else did you find value?

STEVE  We found particular value in the insured specialty sector. A specialty
state is a state with high state income taxes, such as California and New York.
Normally, municipal bonds issued in these states are more expensive than the
national norm (and, therefore, offer lower yields) because of the increased
demand for these bonds from income-tax payers in that state.
     In the final three months of 1999, however, new issue supply was large and
issuers in several specialty states had to offer their bonds at yields
comparable to national municipal bonds. We took advantage of this unusual market
dynamic to purchase several specialty state bonds for the fund.
     As supply abated in the first quarter of 2000 and the availability of bonds
became more limited, specialty state bonds generally performed well.

Q  What is your outlook for the coming months?

STEVE  From a historical perspective, municipals are priced attractively
relative to their Treasury counterparts. (Of course, Treasuries are backed by
the full faith and credit of the U.S. government.) To the extent that investors
seek out value in the bond market, municipals could benefit.

TOM  In addition to Federal Reserve policy, the near term outlook for municipals
will be influenced by the level of new issuance in the market. Our view is that
the municipal market could continue to be bolstered by diminished supply, as
long as demand remains constant or improves.

R share returns adjusted for differences in sales charges and expenses, which
are primarily differences in distribution and service fees. Class A shares have
a 4.2% maximum sales charge. Class B shares have a CDSC that begins at 5% for
redemptions during the first year after purchase and declines periodically to 0%

+Class R shares returns are actual. Class A, B and C share returns are actual
for the period since class inception; returns prior to class inception are
Class R share returns adjusted for differences in sales charges and expenses,
which are primarily differences in distribution and service fees. Class A shares
have a 4.2% maximum sales charge. Class B shares have a CDSC that begins at 5%
for redemptions during the first year after purchase and declines periodically
to 0% over the following five years. Class B shares automatically convert to
Class A shares eight years after purchase. Class C shares have a 1% CDSC for
redemptions within one year, which is not reflected in the one-year total
return.

 Terms To Know
--------------------------------------------------------------------------------

The following are a few terms used throughout this report.

Duration  A mathematical measure of the price sensitivity of a bond fund's
portfolio to changes in interest rates. Duration is stated in years; typically
the shorter the duration, the less price and return variability you can expect
in the fund's price per share as interest rates change.

Federal Fund Rates  The interest rate charged by banks to lend to other banks
needing overnight loans; this figure is the most sensitive indicator of the
direction of interest rates.

Municipal Bond  A bond issued by a state, city, or other municipality to finance
public works such as the construction of roads or schools. The interest is
usually free from federal income tax and may be free from state and local taxes
as well.

SEC Yield  A standardized measure of the current net market yields on a mutual
fund's investment portfolio.

Taxable Equivalent Yield  The return an investor would have to realize on a
fully taxable investment to equal the stated yield on a tax-exempt investment.

Notes to Financial Statements


1. General Information and Significant Accounting Policies

The Nuveen Flagship Municipal Trust (the "Trust") is an open-end diversified
investment company registered under the Investment Company Act of 1940, as
amended. The Trust comprises the Nuveen Intermediate Duration Municipal Bond
Fund ("Intermediate Duration Municipal Bond") and the Nuveen Insured Municipal
Bond Fund ("Insured Municipal Bond") (collectively, the "Funds"), among others.
The Trust was organized as a Massachusetts business trust on July 1, 1996.

Each fund seeks to provide high tax-free income and preservation of capital
through investments in diversified portfolios of quality municipal bonds.

Effective November 24, 1999, Nuveen Municipal Bond Fund ("Municipal Bond")
changed its name to Nuveen Intermediate Duration Municipal Bond Fund. Also
effective November 24, 1999, the fund will invest in a diversified portfolio of
investment grade quality bonds of various maturities with a weighted average
duration of between three and 10 years. Both changes were approved by the Board
of Trustees of Municipal Bond on November 4, 1999.

The following is a summary of significant accounting policies followed by the
Funds in the preparation of their financial statements in accordance with
accounting principles generally accepted in the United States.

Securities Valuation

The prices of municipal bonds in each Fund's investment portfolio are provided
by a pricing service approved by the Funds' Board of Trustees. When price quotes
are not readily available (which is usually the case for municipal securities),
the pricing service establishes fair market value based on yields or prices of
municipal bonds of comparable quality, type of issue, coupon, maturity and
rating, indications of value from securities dealers and general market
conditions. Temporary investments in securities that have variable rate and
demand features qualifying them as short-term securities are valued at amortized
cost, which approximates market value.

Securities Transactions

Securities transactions are recorded on a trade date basis. Realized gains and
losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. Any securities so purchased are subject to
market fluctuation during this period. The Funds have instructed the custodian
to segregate assets in a separate account with a current value at least equal to
the amount of the when-issued and delayed delivery purchase commitments. At
April 30, 2000, Intermediate Duration Municipal Bond and Insured Municipal Bond
had outstanding when-issued purchase commitments of $8,585,983 and $15,851,324,
respectively.

Investment Income

Interest income is determined on the basis of interest accrued, adjusted for
amortization of premiums and accretion of discounts on long-term debt securities
when required for federal income tax purposes.

Dividends and Distributions to Shareholders

Tax-exempt net investment income is declared monthly as a dividend and payment
is made or reinvestment is credited to shareholder accounts on the first
business day after month-end. Net realized capital gains and/or market discount
from investment transactions, if any, are distributed to shareholders not less
frequently than annually. Furthermore, capital gains are distributed only to the
extent they exceed available capital loss carryforwards.

Distributions to shareholders of tax-exempt net investment income, net realized
capital gains and market discount are recorded on the ex-dividend date. The
amount and timing of distributions are determined in accordance with federal
income tax regulations, which may differ from generally accepted accounting
principles. Accordingly, temporary over-distributions as a result of these
differences may occur and will be classified as either distributions in excess
of net investment income, distributions in excess of net realized gains and/or
distributions in excess of net ordinary taxable income from investment
transactions, where applicable.

Notes to Financial Statements (continued)



Federal Income Taxes

Each Fund is a separate taxpayer for federal income tax purposes. Each Fund
intends to comply with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its tax-exempt net
investment income, in addition to any significant amounts of net realized
capital gains and/or market discount realized from investment transactions. The
Funds currently consider significant net realized capital gains and/or market
discount as amounts in excess of $.001 per share. Furthermore, each Fund intends
to satisfy conditions which will enable interest from municipal securities,
which is exempt from regular federal income tax, to retain such tax-exempt
status when distributed to the shareholders of the Funds. All monthly tax-exempt
income dividends paid during the fiscal year ended April 30, 2000, have been
designated Exempt Interest Dividends. Net realized capital gain and market
discount distributions are subject to federal taxation.

Insurance

Insured Municipal Bond invests in municipal securities which are either covered
by insurance or backed by an escrow or trust account containing sufficient U.S.
Government or U.S. Government agency securities, both of which ensure the timely
payment of principal and interest. Each insured municipal security is covered by
Original Issue Insurance, Secondary Market Insurance or Portfolio Insurance.
Such insurance does not guarantee the market value of the municipal securities
or the value of the Fund's shares. Original Issue Insurance and Secondary Market
Insurance remain in effect as long as the municipal securities covered thereby
remain outstanding and the insurer remains in business, regardless of whether
the Fund ultimately disposes of such municipal securities. Consequently, the
market value of the municipal securities covered by Original Issue Insurance or
Secondary Market Insurance may reflect value attributable to the insurance.
Portfolio Insurance is effective only while the municipal securities are held by
the Fund. Accordingly, neither the prices used in determining the market value
of the underlying municipal securities nor the net asset value of the Fund's
shares include value, if any, attributable to the Portfolio Insurance. Each
policy of the Portfolio Insurance does, however, give the Fund the right to
obtain permanent insurance with respect to the municipal security covered by the
Portfolio Insurance policy at the time of its sale.

Flexible Sales Charge Program

Each Fund offers Class A, B, C and R Shares. Class A Shares are sold with a
sales charge and incur an annual 12b-1 service fee. Class A Share purchases of
$1 million or more are sold at net asset value without an up-front sales charge
but may be subject to a contingent deferred sales charge ("CDSC") if redeemed
within 18 months of purchase. Class B Shares are sold without a sales charge but
incur annual 12b-1 distribution and service fees. An investor purchasing Class B
Shares agrees to pay a CDSC of up to 5% depending upon the length of time the
shares are held by the investor (CDSC is reduced to 0% at the end of six years).
Class B Shares convert to Class A Shares eight years after purchase. Class C
Shares are sold without a sales charge but incur annual 12b-1 distribution and
service fees. An investor purchasing Class C Shares agrees to pay a CDSC of 1%
if Class C Shares are redeemed within one year of purchase. Class R Shares are
not subject to any sales charge or 12b-1 distribution or service fees. Class R
Shares are available only under limited circumstances, or by specified classes
of investors.

Derivative Financial Instruments

The Funds may invest in certain derivative financial instruments including
futures, forward, swap and option contracts, and other financial instruments
with similar characteristics. Although the Funds are authorized to invest in
such financial instruments, and may do so in the future, they did not make any
such investments during the fiscal year ended April 30, 2000.

Expense Allocation

Expenses of each Fund that are not directly attributable to a specific class of
shares are prorated among the classes based on the relative net assets of each
class. Expenses directly attributable to a class of shares, which presently only
includes 12b-1 distribution and service fees, are recorded to the specific
class.

Custodian Fee Credit

Each Fund has an arrangement with the custodian bank whereby the custodian fees
and expenses are reduced by credits earned on each Fund's cash on deposit with
the bank. Such deposit arrangements are an alternative to overnight investments.

Use of Estimates

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States 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 increases and
decreases in net assets from operations during the reporting period. Actual
results may differ from those estimates.

Under the Trust's investment management agreement with Nuveen Advisory Corp.
(the "Adviser"), a wholly owned subsidiary of The John Nuveen Company, each
Fund pays an annual management fee, payable monthly, at the rates set forth
below which are based upon the average daily net assets of each Fund as
follows:

<TABLE>
<CAPTION>

Average Daily Net Assets                Management Fee
---------------------------------------------------------
<S>                                     <C>
For the first $125 million                  .5000 of 1%
For the next $125 million                   .4875 of 1
For the next $250 million                   .4750 of 1
For the next $500 million                   .4625 of 1
For the next $1 billion                     .4500 of 1
For net assets over $2 billion              .4250 of 1
=========================================================
</TABLE>

The management fee compensates the Adviser for overall investment advisory and
administrative services, and general office facilities. The Trust pays no
compensation directly to those of its Trustees who are affiliated with the
Adviser or to its officers, all of whom receive remuneration for their services
to the Trust from the Adviser or its affiliates.

The Adviser has agreed to waive part of its management fees or reimburse certain
expenses of each Fund in order to limit total expenses to .75 of 1% of the
average daily net asset value of Intermediate Duration Municipal Bond and .975
of 1% of the average daily net asset value of Insured Municipal Bond, excluding
any 12b-1 fees applicable to Class A, B and C Shares. The Adviser may also
voluntarily agree to reimburse additional expenses from time to time, which may
be terminated at any time at its discretion.

During the fiscal year ended April 30, 2000, John Nuveen & Co Incorporated (the
"Distributor"), a wholly-owned subsidiary of The John Nuveen Company, collected
sales charges on purchases of Class A Shares of approximately $278,100 and
$229,000 for Intermediate Duration Municipal Bond and Insured Municipal Bond,
respectively, of which approximately $259,600 and $229,000, respectively, were
paid out as concessions to authorized dealers. The Distributor also received
12b-1 service fees on Class A Shares, substantially all of which were paid to
compensate authorized dealers for providing services to shareholders relating to
their investments.

During the fiscal year ended April 30, 2000, the Distributor compensated
authorized dealers directly with approximately $215,300 and $359,600 in
commission advances at the time of purchase for Intermediate Duration Municipal
Bond and Insured Municipal Bond, respectively. To compensate for commissions
advanced to authorized dealers, all 12b-1 service fees collected on Class B
Shares during the first year following a purchase, all 12b-1 distribution fees
collected on Class B Shares, and all 12b-1 service and distribution fees
collected on Class C Shares during the first year following a purchase are
retained by the Distributor. During the fiscal year ended April 30, 2000, the
Distributor retained approximately $118,300 and $154,800 in such 12b-1 fees for
Intermediate Duration Municipal Bond and Insured Municipal Bond, respectively.
The remaining 12b-1 fees charged to the Funds were paid to compensate authorized
dealers for providing services to shareholders relating to their investments.
The Distributor also retained approximately $94,500 and $105,400 of CDSC on
share redemptions for Intermediate Duration Municipal Bond and Insured Municipal
Bond, respectively, during the fiscal year ended April 30, 2000.

</TABLE>

Certain long-term and intermediate-term investments owned by the Funds are
either covered by insurance issued by several private insurers or are backed by
an escrow or trust containing U.S. Government or U.S. Government agency
securities, either of which ensure the timely payment of principal and interest
in the event of default (37% for Intermediate Duration Municipal Bond and 100%
for Insured Municipal Bond). Such insurance or escrow, however, does not
guarantee the market value of the municipal securities or the value of the
Funds' shares.

Portfolio of Investments of each Fund.

Report of Independent Public Accountants



To the Board of Trustees and Shareholders of
Nuveen Flagship Municipal Trust:

We have audited the accompanying statements of net assets, including the
portfolios of investments, of the Nuveen Intermediate Duration Municipal Bond
Fund and Nuveen Insured Municipal Bond Fund (two of the portfolios constituting
the Nuveen Flagship Municipal Trust (a Massachusetts business trust)), as of
April 30, 2000, and the related statements of operations, statements of changes
in net assets and the financial highlights for the periods indicated thereon.
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 auditing standards generally accepted
in the 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. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. Our procedures included confirmation of securities
owned as of April 30, 2000, by correspondence with the custodian and brokers. As
to securities purchased but not received, we requested confirmation from brokers
and, when replies were not received, we carried out alternative auditing
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, the financial statements and financial highlights referred to
above present fairly, in all material respects, the net assets of the Nuveen
Intermediate Duration Municipal Bond Fund and Nuveen Insured Municipal Bond Fund
of the Nuveen Flagship Municipal Trust as of April 30, 2000, and the results of
their operations, the changes in their net assets and their financial highlights
for the periods indicated thereon in conformity with accounting principles
generally accepted in the United States.

DEAR

Shareholder,

As personal wealth continues to grow at an ever-increasing rate, people are
realizing the power of their investments to do good and to make a difference in
their families and communities now and for generations to come.

Setting financial goals is an important first step toward building wealth. At
Nuveen Investments, we believe those goals should not be considered ends in
themselves. Rather, you and your financial advisor's focus should be on
realizing your life's dreams -- the things that matter most to you and how you
can make them happen -- or make them better.

Through a well-crafted financial plan, you have the chance to shape future
generations -- to broaden your sphere of influence -- to leave your legacy.

As you develop that plan, you'll want to consider the different ways your
success can benefit others. You may find that you want to create a new set of
goals to achieve this. Working with your financial advisor, you have the ability
to make those dreams a reality -- for yourself and future generations.

Family Wealth Management Too often, family wealth management is thought of in
one dimension -- as the stewardship of your household's financial resources. At
Nuveen Investments, we think of family wealth management as the map to help you
reach your financial, and your life's, destinations. It's a multi-faceted
strategy to plan for not just your needs, but the needs of future generations.
     We are dedicated to helping you and your financial advisor develop a family
wealth management strategy unique to you and your goals and values.

A Trusted Resource  As you face some of the most important, lasting decisions
you and your family will make, you'll want to draw upon the support, counsel and
objectivity of a trusted advisor. That's because your financial advisor has the
expertise and access to other professionals who can help you make informed
choices -- choices that affect not only your loved ones today, but those your
legacy will touch in the future.

     Your financial advisor can provide sound financial insight, an integrated
approach to your investments and can serve as a knowledgeable friend with your
family's best interests at heart.

                                                            ANNUAL REPORT page 1
<PAGE>

     In addition, we believe the potential presence of inflation and price
swings in the markets reinforce the importance of working with an advisor,
staying focused on the long term and adhering to your financial plan.  With a
sound plan in place, you may be better positioned to weather the markets' ups
and downs.

     In fact, you may be reading this report at the suggestion of your financial
advisor. We've prepared the following interview to let you know what the
investment and research management teams have done during your fund's fiscal
period.

     For more information on any Nuveen investment, including a prospectus,
contact your financial advisor. Or call Nuveen at (800) 621-7227 or visit our
Internet site at www.nuveen.com. Please read the prospectus carefully before you
invest or send money.

     Since 1898, Nuveen has been synonymous with investments that stand the test
of time. We are committed to maintaining that reputation and working with
financial advisors to provide investment solutions that help individuals achieve
their lives dreams. Thank you for your continued confidence.

Sincerely,

Tim Schwertfeger

NUVEEN FLAGSHIP FLORIDA MUNICIPAL BOND FUND

From the Portfolio Managers' Perspective
--------------------------------------------------------------------------------

For nearly a year, the Federal Reserve Board (the Fed) has continued on a track
to raise interest rates in an attempt to stymie inflation. These "tightening"
measures put pressure on nearly all bonds, including municipal securities. Rick
Huber, portfolio manager of the Nuveen Flagship All-American Municipal Bond Fund
and Nuveen Flagship Limited Term Municipal Bond Fund, and Paul Brennan,
portfolio manager of Nuveen Flagship Intermediate Municipal Bond Fund, discuss
the economic environment in which the funds participated, as well as their
funds' performance and key investment strategies

+ The Morningstar ratings are overall for the municipal bond category and relate
to Class A shares only; the other classes may vary. Morningstar proprietary
ratings reflect historical risk-adjusted performance as of 4/30/00 and are
subject to change every month. Past performance is no guarantee of future
results. Ratings are calculated from the funds' three-, five-, and 10-year
average annual returns (if applicable) in excess of 90-day Treasury bill
returns, with appropriate fee adjustments, and a risk factor that reflects fund
performance below 90-day T-bill returns.

Nuveen Flagship All-American Municipal Bond Fund received 3 stars for the 3-and
5-year periods and 4 stars for the 10-year period.

The Nuveen Intermediate Fund received 3 stars for the 3-year period and 4 stars
for the 5-year period.

The Nuveen Flagship Limited Term Fund received 4 stars for the 3- and 5-year
periods and 5 stars for the 10-year period.

The top 10% of the funds in a broad asset class receive five stars, and the next
22.5% receive four stars, and the next 35% receive three stars. The funds were
rated among 1,692 funds for the three-year period, 1,438 for the five-year
period and 405 for the 10-year period.

Performance figures are quoted for Class A shares at net asset value. Comments
cover the fiscal 12-month period ended April 30, 2000. The views expressed
reflect those of the portfolio management team and are subject to change at any
time, based on market and other conditions.

A voluntary expense limitation was in place for Nuveen Intermediate Municipal
Bond Fund during the period. Total return would have been less.


Q    How would you describe the overall fixed-income investing environment
during the past 12 months?

Rick Rising interest rates translated into a difficult bond market environment.
The Fed raised interest rates five times during the past 12 months, lifting the
federal funds rates -- the rate banks charge each other for overnight loans --to
6%, a five-year high. After the fund's fiscal annual period ended, a sixth hike
followed on May 16, bringing the fed funds rate to 6.50%.

     These moves were intended to curb the strong U.S. economy and stifle any
inflationary pressures that might be brewing as a result. Bond yields rose in
response, and their prices -- which generally move in the opposite direction of
their yields -- posted losses.

PAUL Supply and demand also played a role in determining municipal bond returns
during the past 12 months.

     On a positive note, the supply of municipal bonds dwindled as rising rates
extinguished opportunities for issuers to refinance or refund older, more
expensive debt. In addition, the strength of national and local economies
translated into higher revenues and tax collections for many municipalities,
thereby reducing their debt financing needs. These developments translated into
a 40% reduction of the supply of municipals in the first quarter of 2000,
compared to the same quarter a year earlier.

     Demand, on the other hand, was spotty. Lured by the red-hot returns of
technology and other stocks, investors generally avoided fixed-income
investments throughout most of 1999. In early 2000, however, the demand for
municipals became strong again when technology stocks experienced a downturn and
municipal bond yields touched 6%.

Q What investment strategies did you employ during the past year?

RICK To maintain a competitive distribution yield, each fund had significant
holdings in BBB-rated and non-rated securities, which generally lagged their
higher-quality counterparts during the past year. As interest rates rose,
investors' aversion to risk seemingly intensified, and lower-quality and non-
rated municipal bonds fell out of favor. This occurred despite the fact that the
strong U.S. economy meant improving credit fundamentals for many issuers of BBB-
rated and non-rated bonds.

     In response to investors' ongoing avoidance of lower-quality bonds, we
reduced our stake in them over the past six months. That said, we continue to
hold some selected BBB-rated and non-rated hospital, industrial development and
utility bonds because they offered attractive yields and the potential to
outpace higher-rated securities if they move back into favor.

Q Where did you find attractive opportunities during the period?

RICK We capitalized on the recent rise in interest rates and the resulting
decline in bond prices to improve All-American's tax efficiency. As rates rose,
prices on some of the fund's holdings fell. By selling certain bonds at a loss,
we created tax-loss carryforwards that can be used to offset current and/or
future realized capital gains. An additional benefit of these transactions is
that we used the proceeds from the sale of bonds to finance purchases of new
bonds with higher income streams.

Q Paul, what can you tell us about Nuveen Flagship Intermediate Municipal Bond
Fund's performance?

PAUL The fund reported a total return of -2.17% for the 12-month period ended
April 30, 2000 for Class A shares on net asset value. In comparison, the Lipper
National Intermediate Municipal Fund category reported a -1.17% total return for
the 12-month period and the Lehman Brothers Municipal Bond Index (7-year)
returned -0.03%./2/,/5/ Shareholders in the 31% federal income tax bracket would
have had to earn a total return of -0.08% on a taxable investment to have earned
the equivalent of their fund's tax-exempt total return for the 12-month
period./3/

     As of April 30, 2000, the fund's SEC 30-day yield was 4.97%. For investors
in the 31% federal income tax bracket, that is equivalent to a yield of 7.20% on
a taxable investment./3/

     The fund's lag stemmed mostly from our focus on maximizing distribution
yield by maintaining a somewhat longer duration than our peers. Duration is a
measure of a bond's interest rate sensitivity; the longer a bond's duration, the
more its share price will fall when rates rise and vice versa. Among
intermediate maturity bonds, an investor typically can pick up a fair amount of
additional yield for moving out each successive year of maturity. With interest
rates on the rise as they were during the fiscal period, however, the fund's
longer duration detracted from performance.

Q What were some of your other key strategies?

PAUL Like Nuveen Flagship All-American and Nuveen Flagship Limited Term
Municipal Bond Fund, we identified several opportunities to do some tax loss
swapping. When we made those trades, we looked to improve the fund's overall
call protection, which can help insulate the fund from the inopportune
redemption of bonds that can occur when interest rates fall.

     Recently, for example, we purchased bonds issued by the City of Chicago,
the District of Columbia and Boone McHenry Dekalb School District, all of which
carried call protection in excess of 10 years.

     We also maintained a significant position in non-rated bonds and those
rated BBB, which is at the lower end of the investment grade credit rating
scale, as judged by Standard & Poor's and Moody's Investors Service.

     As Rick explained, a lack of demand caused these bonds to underperform
their higher-quality counterparts over the past year. But we think that the pain
they suffered in response was overdone, and that selected non- and BBB-rated
securities offer the potential to outperform. Furthermore, they offer a very
attractive yield advantage over higher-rated securities, although they do carry
more risk.

Q  What's ahead for the municipal market and these three Nuveen Flagship
municipal bond funds?

RICK  At the end of the period, bond prices seemingly reflected investors'
expectations for further interest rate hikes. Aside from interest rates, supply
and demand conditions will also play a role in the performance of municipal
bonds. We expect supply to remain low, a consequence of higher interest rates.
Demand is more of an unknown. As we mentioned in the beginning, investors
generally avoided fixed-income investments of all types during 1999 in favor of
stocks. If the trend we've seen in early 2000 continues and investors continue
to seek out more fixed-income investments, municipals could benefit.

3  Taxable equivalent yield/total return represents the yield/total return on a
   taxable investment necessary to equal the yield of the Nuveen Fund on an
   after-tax basis. The taxable-equivalent yield shown is based on the 30-day
   SEC yield and a federal income tax rate of 31%. The taxable equivalent total
   return is based on the fund's one-year total return and the 31% federal tax
   rate.

+ Class A share returns are actual. Class B, C and R share returns are actual
  for the period since class inception; returns prior to class inception are
  Class A share returns adjusted for differences in sales charges and expenses,
  which are primarily differences in distribution and service fees. Class A
  shares have a 4.2% maximum sales charge. Class B shares have a CDSC that
  begins at 5% for redemptions during the first year after purchase and declines
  periodically to 0% over the following five years. Class B shares automatically
  convert to Class A shares eight years after purchase. Class C shares have a 1%
  CDSC for redemptions within one year, which is not reflected in the one-year
  total return.

Terms To Know

The following are a few terms used throughout this report.

Duration A mathematical measure of the price sensitivity of a bond fund's
portfolio to changes in interest rates. Duration is stated in years; typically
the shorter the duration, the less price and return variability you can expect
in the fund's price per share as interest rates change.

Fed Tightening When the Federal Reserve is following tight money policy, it is
essentially decreasing the money supply by increasing the fed funds rate and
making money more expensive to borrow. The intention is to slow the growth of
the economy and curtail inflation.

Federal Fund Rates The interest rate charged by banks to lend to other banks
needing overnight loans; this figure is the most sensitive indicator of the
direction of interest rates.

Municipal Bond A debt issued by a state, city, or other municipality to finance
public works such as the construction of roads or schools. The interest is
usually free from federal income tax and may be free from state and local taxes
as well.

SEC Yield A standardized measure of the current net market yields on a mutual
fund's investment portfolio.

Taxable Equivalent Yield The return an investor would have to realize on a fully
taxable investment to equal the stated yield on a
tax-exempt investment.

 Terms To Know

The following are a few terms used throughout this report.

Duration A mathematical measure of the price sensitivity of a bond fund's
portfolio to changes in interest rates. Duration is stated in years; typically
the shorter the duration, the less price and return variability you can expect
in the fund's price per share as interest rates change.

Fed Tightening When the Federal Reserve is following tight money policy, it is
essentially decreasing the money supply by increasing the fed funds rate and
making money more expensive to borrow. The intention is to slow the growth of
the economy and curtail inflation.

Federal Fund Rates The interest rate charged by banks to lend to other banks
needing overnight loans; this figure is the most sensitive indicator of the
direction of interest rates.

Municipal Bond A debt issued by a state, city, or other municipality to finance
public works such as the construction of roads or schools. The interest is
usually free from federal income tax and may be free from state and local taxes
as well.

SEC Yield A standardized measure of the current net market yields on a mutual
fund's investment portfolio.

Taxable Equivalent Yield The return an investor would have to realize on a fully
taxable investment to equal the stated yield on a tax-exempt investment.

NUVEEN HIGH YIELD MUNICIPAL BOND FUND

From the Portfolio Manager's Perspective
------------------------------------------------------------------------------

1 The Lipper Peer Group returns represent the total return of the 57 funds in
  the Lipper High Yield Municipal Debt Funds category for the period from June
  30, 1999, through April 30, 2000 and the 59 funds in the Lipper category for
  the year-to-date period ending April 30, 2000. The Lipper return is compared
  to Nuveen High Yield Municipal Bond Fund's performance since its inception
  June 7, 1999. The fund's return from June 30, 1999 to April 30, 2000, was
  0.16%. The returns assume reinvestment of dividends and do not reflect any
  applicable sales charges.

Investment by the fund in lower-rated and nonrated securities presents greater
risk of loss of principal than investments in investment-grade securities.

Performance figures are quoted for Class A shares at net asset value. Comments
cover the period from the fund's inception on June 7, 1999, through its fiscal
year end, April 30, 2000. The views expressed reflect those of the portfolio
management team and are subject to change at any time, based on market and other
conditions.

A voluntary expense limitation was in place for Nuveen High Yield Municipal Bond
Fund during the period.

Nuveen High Yield Municipal Bond Fund features portfolio management by Nuveen
Investment Management, a team of portfolio managers and research analysts
committed to a disciplined, research-oriented investment strategy. To help you
understand the fund's performance during its fiscal year ending April 30, 2000,
we spoke with Steve Peterson, lead portfolio manager of the fund.

Q The Nuveen High Yield Municipal Bond Fund began operations on June 7, 1999.
-
The fund reported a total return of -2.69% from its inception through April 30,
2000. Although not posting a positive return, the fund did outperform the Lipper
High Yield Municipal Debt Fund category average of -3.03.1 It looks like high
yield municipal bond funds in general had a tough time. What happened in this
market over the period?

STEVE The municipal bond market had a very challenging year in 1999. New
-----
issuance was stagnant, and demand was flat. The stock market frenzy throughout
1999 kept investors' attention, not the fixed income market. The residual
effects of that frenzy seemed to keep investors coming back for more, even amid
the unprecedented amount of volatility in the Dow Jones Industrial Average and
the Nasdaq Composite Index during the first four months of 2000.

       Although stocks took a beating, we still didn't see the "flight-to-
quality" into bonds that we usually expect when the stock market goes sour.
There was a definite lack of interest in the bond market -- and high yield
municipals in particular -- throughout the period. But that wasn't a bad thing
at all, in our opinion. In fact, we were able to take advantage of a market full
of opportunities to find attractive value and yields and even increase the
fund's dividend rate.

Q For this fund, you look for municipal bonds that are undervalued and
-
therefore selling at attractive prices or yields. So during this period, you
really saw the out-of-favor high yield municipal market as full of potential?

STEVE Yes. The entire high yield municipal market was out of favor, with both
-----
issuance and demand down, but we still found very viable bond issues for the
fund. Our overreaching goal in any environment is to find bonds that we believe
are mispriced, that through our research we determine offer strong potential.

Q Do you have any specific examples?
-

STEVE Ohio Bayshore is a great example. It's a small independent power plant
-----
under construction that, when completed, should provide some of the lowest cost
power in Ohio, a state that generally has had very high-cost energy. The project
was behind schedule, which was why this issue was out of favor. But the reason
for the delay was simply that the tight labor market made welders and
construction workers who were available to work hard to come by. That, in our
opinion, was the temporary result of a

 ANNUAL REPORT page 10
<PAGE>

strong economy, not a reflection of poor management. These bonds were issued
with attractive yields at 7.75% to 8%.

     We also continued to find potential in the embattled healthcare sector,
still under pressure from cuts in federal Medicare and Medicaid reimbursement,
aggressive HMO pricing and the move from inpatient to outpatient care. But even
in these conditions, we feel healthcare is something people will always need,
and those organizations that have positioned themselves favorably can offer very
attractive bond issues while remaining competitive.

     One such example is Kentucky Appalachian Regional Healthcare. This issue
was backed by six Kentucky and Virginia hospitals and offered a yield of nearly
9.5%. Keep in mind that's a tax-free yield; the equivalent yield on a similar
taxable bond would be close to 16%. We believe this security offered exceptional
value since these hospitals offer essential services and are insulated from
competition due to their rural location -- the nearest competing hospital is
more than an hour-and-a-half away. Their overall debt level was also very
moderate, which impressed us.

     It was impressive yields such as these that allowed us to increase the
dividend during the fiscal period.


Q Typically, a rising interest rate environment is not a very favorable one for
-
bonds, yet if we look at the year-to-date period as of April 30, 2000 -- a
period in which the Federal Reserve (the Fed) raised rates twice -- the fund
returned 2.01%, versus the Lipper category average for the same period of
0.64%.1 The fund's tax-free return even outpaced the stock market -- negative
0.04% measured by the S&P 500 Index.2 How do you explain this?

STEVE The stock market tends to operate on a different level than that of the
-----
bond market. Particularly during the first part of 2000, investors seemed to
take it to an entirely different plane. It seemed to be based on random guesses
on where prices would go, with little regard for fundamentals like profits and
cash flows. Bonds, on the other hand, are priced according to factors like
interest rates and credit quality of issuers.

     The high yield municipal bond market itself began a rebound after a rocky
1999. The very structure of high yield municipal bonds makes them less sensitive
to changing interest rates. Their sensitivity lies more in the credit quality of
the issuer, otherwise known as credit risk.  While higher credit risk is
inherent in a high yield fund, we work to mitigate credit risk for the fund
through thorough analysis and sometimes even by negotiating structure directly
with the issuer.

     Since no one but Chairman Alan Greenspan's Fed has any control over
interest rates, we tried to minimize the fund's exposure to interest rate risk
wherever possible. We consciously sought out bonds that offered shorter
maturities to help decrease the fund's duration, which is a measure of how
sensitive the fund is to interest rate risk. A shorter duration means less
interest rate sensitivity -- important in this environment.

Another factor in this market was the yield differential between lower-rated
bonds, such as those the fund invests in, and higher-rated bonds. The wider this
differential -- or "spread" -- the more affordable high yield municipals are,
and therefore the more the potential for gains, even factoring in the higher
risk potential.

For example, one bond we bought recently paid a yield premium of 375 basis
points -- or nearly four percentage points -- over an otherwise similar higher-
rated bond. One year ago we were seeing spreads of only 100 to 125 basis points,
or around one percent difference in yields.

Q What is your outlook for the near future in the high yield municipal bond
-
market?

STEVE Throughout the coming months, we plan to maintain the fund's duration at
-----
or near its current low level to help keep its sensitivity to interest rates
down.

      However, we are optimistic that future Fed interest rate increases will be
relatively modest. It is our experience that Fed rate increases take about 12 to
18 months to have their intended effect on the economy, so the impact should
begin to emerge soon.

 Terms To Know

The following are a few terms used throughout this report.

Duration A mathematical measure of the price sensitivity of a bond fund's
portfolio to changes in interest rates. Duration is stated in years; typically
the shorter the duration, the less price and return variability you can expect
in the fund's price per share as interest rates change.

Federal Fund Rates The interest rate charged by banks to lend to other banks
needing overnight loans; this figure is the most sensitive indicator of the
direction of interest rates.

Municipal Bond An IOU issued by a state, city, or other municipality to finance
public works such as the construction of roads or schools. The interest is
usually free from federal income tax and may be free from state and local taxes
as well.

SEC Yield A standardized measure of the current net market yields on a mutual
fund's investment portfolio.

Taxable Equivalent Yield The return an investor would have to realize on a fully
taxable investment to equal the stated yield on a tax-exempt investment.

3 Taxable-equivalent yield/total return represents the yield/total return on a
taxable investment necessary to equal the yield/total return of the Nuveen fund
on an after-tax basis. The taxable equivalent yield shown is based on the 30-day
SEC yield and a federal income tax rate of 31%. The taxable equivalent total
return is based on the fund's one-year total return and the 31% federal tax
rate.

1.  General Information and Significant Accounting Policies

The Nuveen Flagship Municipal Trust (the "Trust") is an open-end diversified
investment company registered under the Investment Company Act of 1940, as
amended. The Trust comprises the Nuveen Flagship All-American Municipal Bond
Fund ("All-American"), the Nuveen Flagship Intermediate Municipal Bond Fund
("Intermediate"), the Nuveen Flagship Limited Term Municipal Bond Fund ("Limited
Term") and the Nuveen High Yield Municipal Bond Fund ("High Yield")
(collectively, the "Funds"), among others. The Trust was organized as a
Massachusetts business trust on July 1, 1996.

After the close of business on September 11, 1998, Nuveen Flagship Alabama
Municipal Bond Fund ("Alabama") and Nuveen  Flagship South Carolina Municipal
Bond Fund ("South Carolina") reorganized into All-American. Prior to these
reorganizations Alabama and South Carolina were each a series of the Nuveen
Flagship Multistate Trust III, an open-end investment company. Alabama and South
Carolina had fiscal year ends of May 31 prior to being reorganized into All-
American which has an April 30 fiscal year end.

After the close of business on September 11, 1998, Nuveen Flagship Florida
Intermediate Municipal Bond Fund ("Florida Intermediate") reorganized into
Intermediate. Prior to the reorganization Florida Intermediate was a series of
the Nuveen Flagship Multistate Trust I, an open-end investment company. Florida
Intermediate had a fiscal year end of May 31 prior to being reorganized into
Intermediate which has an April 30 fiscal year end.

All-American, Intermediate and Limited Term seek to provide high tax-free income
and preservation of capital through investments in diversified portfolios of
quality municipal bonds.

High Yield invests substantially all of its assets in municipal bonds for high
current income exempt from regular federal income taxes and capital
appreciation. Under normal circumstances, at least 65% of the Fund's assets will
be invested in medium to low-quality municipal bonds and may also invest in
defaulted municipal bonds, inverse floating rate securities, municipal forwards
and short-term municipal investments.

The following is a summary of significant accounting policies followed by the
Funds in the preparation of their financial statements in accordance with
accounting principles generally accepted in the United States.

Securities Valuation

The prices of municipal bonds in each Fund's investment portfolio are provided
by a pricing service approved by the Fund's Board of Trustees. When price quotes
are not readily available (which is usually the case for municipal securities),
the pricing service establishes fair market value based on yields or prices of
municipal bonds of comparable quality, type of issue, coupon, maturity and
rating, indications of value from securities dealers and general market
conditions. Temporary investments in securities that have variable rate and
demand features qualifying them as short-term securities are valued at amortized
cost, which approximates market value.

Securities Transactions

Securities transactions are recorded on a trade date basis. Realized gains and
losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. Any securities so purchased are subject to
market fluctuation during this period. The Funds have instructed the custodian
to segregate assets in a separate account with a current value at least equal to
the amount of the when-issued and delayed delivery purchase commitments. At
April 30, 2000, All-American had an outstanding when-issued purchase commitment
of $6,195,660. There were no such outstanding purchase commitments in any of the
other Funds.

Investment Income

Interest income is determined on the basis of interest accrued, adjusted for
amortization of premiums and accretion of discounts on long-term debt securities
when required for federal income tax purposes.

Dividends and Distributions to Shareholders

Tax-exempt net investment income is declared monthly as a dividend and payment
is made or reinvestment is credited to shareholder accounts on the first
business day after month-end. Net realized capital gains and/or market discount
from investment transactions, if any, are distributed to shareholders not less
frequently than annually. Furthermore, capital gains are distributed only to the
extent they exceed available capital loss carryforwards.

Distributions to shareholders of tax-exempt net investment income, net realized
capital gains and/or market discount are recorded on the ex-dividend date. The
amount and timing of distributions are determined in accordance with federal
income tax regulations, which may differ from generally accepted accounting
principles. Accordingly, temporary over-distributions as a result of these
differences may occur and will be classified as either distributions in excess
of net investment income, distributions in excess of net realized gains and/or
distributions in excess of net ordinary taxable income from investment
transactions, where applicable.

Federal Income Taxes

Each Fund is a separate taxpayer for federal income tax purposes. Each Fund
intends to comply with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its tax-exempt net
investment income, in addition to any significant amounts of net realized
capital gains and/or market discount from investment transactions. The Funds
currently consider significant net realized capital gains and/or market discount
as amounts in excess of $.001 per share. Furthermore, each Fund intends to
satisfy conditions which will enable interest from municipal securities, which
is exempt from regular federal income tax, to retain such tax-exempt status when
distributed to the shareholders of the Funds. All monthly tax-exempt income
dividends paid during the fiscal year ended April 30, 2000, have been designated
Exempt Interest Dividends. Net realized capital gain and market discount
distributions are subject to federal taxation.

Flexible Sales Charge Program

Each Fund offers Class A, C and R Shares. All-American and High Yield also offer
Class B Shares. Class A Shares are sold with a sales charge and incur an annual
12b-1 service fee. Class A Share purchases of $1 million or more are sold at net
asset value without an up-front sales charge but may be subject to a contingent
deferred sales charge ("CDSC") if redeemed within 18 months of purchase. Class B
Shares are sold without a sales charge but incur annual 12b-1 distribution and
service fees. An investor purchasing Class B Shares agrees to pay a CDSC of up
to 5% depending upon the length of time the shares are held by the investor
(CDSC is reduced to 0% at the end of six years). Class B Shares convert to Class
A Shares eight years after purchase. Class C Shares are sold without a sales
charge but incur annual 12b-1 distribution and service fees. An investor
purchasing Class C Shares agrees to pay a CDSC of 1% if Class C Shares are
redeemed within one year of purchase. Class R Shares are not subject to any
sales charge or 12b-1 distribution or service fees. Class R Shares are available
only under limited circumstances, or by specified classes of investors.

Derivative Financial Instruments

The Funds may invest in certain derivative financial instruments including
futures, forward, swap and option contracts, and other financial instruments
with similar characteristics. Although the Funds are authorized to invest in
such financial instruments, and may do so in the future, they did not make any
such investments during the fiscal year ended April 30, 2000.

Expense Allocation

Expenses of each Fund that are not directly attributable to a specific class of
shares are prorated among the classes based on the relative net assets of each
class. Expenses directly attributable to a class of shares, which presently only
includes 12b-1 distribution and service fees, are recorded to the specific
class.

Custodian Fee Credit

Each Fund has an arrangement with the custodian bank whereby the custodian fees
and expenses are reduced by credits earned on each Fund's cash on deposit with
the bank. Such deposit arrangements are an alternative to overnight investments.

Use of Estimates

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States 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 increases and
decreases in net assets from operations during the reporting period. Actual
results may differ from those estimates.

Certain long-term and intermediate-term investments owned by the Funds are
either covered by insurance issued by several private insurers or are backed by
an escrow or trust containing U.S. Government or U.S. Government agency
securities, both of which ensure the timely payment of principal and interest in
the event of default (33% for All-American, 33% for Intermediate, 31% for
Limited Term and 5% for High Yield). Such insurance or escrow, however, does not
guarantee the market value of the municipal securities or the value of any of
the Funds' shares.

For additional information regarding each investment security, refer to the
Portfolio of Investments of each Fund.

Report of Independent Public Accountants



To the Board of Trustees and Shareholders of
Nuveen Flagship Municipal Trust:

We have audited the accompanying statements of net assets, including the
portfolios of investments, of Nuveen Flagship All-American Municipal Bond Fund,
Nuveen Flagship Intermediate Municipal Bond Fund, Nuveen Flagship Limited Term
Municipal Bond Fund and Nuveen High Yield Municipal Bond Fund (collectively, the
"Funds") (four of the portfolios constituting the Nuveen Flagship Municipal
Trust (a Massachusetts business Trust)), as of April 30, 2000, and the related
statements of operations, statements of changes in net assets and the financial
highlights for the periods indicated thereon. These financial statements and
financial highlights are the responsibility of the Funds' management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits. The financial highlights for the Funds
for the years ended April 30, 1997 and prior were audited by other auditors
whose report dated June 13, 1997, expressed an unqualified opinion on those
financial highlights.

We conducted our audits in accordance with auditing standards generally accepted
in the 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. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. Our procedures included confirmation of securities
owned as of April 30, 2000, by correspondence with the custodian and brokers. As
to securities purchased but not received, we requested confirmation from
brokers, and when replies were not received, we carried out alternative auditing
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, the financial statements and financial highlights referred to
above present fairly, in all material respects, the net assets of the Nuveen
Flagship All-American Municipal Bond Fund, Nuveen Flagship Intermediate
Municipal Bond Fund, Nuveen Flagship Limited Term Municipal Bond Fund and Nuveen
High Yield Municipal Bond Fund of the Nuveen Flagship Municipal Trust as of
April 30, 2000, the results of their operations, the changes in their net
assets, and their financial highlights for the periods indicated thereon in
conformity with accounting principles generally accepted in the United States.
