TO OUR SHAREHOLDERS

The Municipal Market Environment
During the six months ended July 31, 2000, US domestic economic
growth remained robust. After growing at a 4.2% annual rate in 1999,
US domestic economic growth expanded at a 4.8% rate during the first
quarter of 2000 and at a 5.2% rate during the second quarter.
However, despite these significant growth rates, few price measure
indicators have shown any meaningful signs of future price pressures
at the consumer level, despite the lowest unemployment rates since
1970. With few signs of any economic slowdown, the Federal Reserve
Board continued to raise short-term interest rates in February,
March and May 2000. The Federal Reserve Board cited both the
continued growth of US employment and the continued strength of US
equity markets as reasons for attempting to moderate US economic
growth before inflationary price pressures can occur.

However, since then fixed-income markets have largely ignored strong
economic fundamentals and concentrated upon very positive technical
supply factors. Declining bond issuance--both current, and more
importantly, expected future issuance--helped push bond yields lower
into mid-April 2000. In late January and early February 2000, the US
Treasury announced its intention to reduce the amounts to be
auctioned in the quarterly Treasury note and bond auctions.
Furthermore, budgetary surpluses allowed the US Treasury to
repurchase outstanding, higher-couponed Treasury issues, primarily
in the 15-year and longer maturity sector. Both these actions
resulted in significant reduction in the outstanding supply of
longer-dated maturity US Treasury debt. Domestic and international
investors quickly began to accumulate what was expected to become a
scarce commodity and bond prices quickly rose.

By mid-April 2000, US Treasury bond yields had declined more than 80
basis points (0.80%) to 5.67%. During the remainder of the period,
US Treasury bond prices were volatile as strong economic reports and
investors' concerns of additional moves by the Federal Reserve Board
occasionally overshadowed the positive technical position of the
long-term US Treasury bond market.

Recently, a number of economic indicators have begun to suggest that
the actions taken by the Federal Reserve Board in 1999 and early
2000 have started to affect US economic growth. Both new home sales
and consumer spending have slowed, suggesting that economic growth
may subside into a 4%--4.5% range by late 2000. In our opinion, this
range of growth was targeted by the Federal Reserve Board as being
sustainable, given current productivity measures, without
endangering the present benign inflationary environment.

By June, investor focus returned to the dwindling supply of long-
term US Treasury securities and bond prices generally rose for the
remainder of the period. The decline in long-term US Treasury bond
yields resulted in an inverted yield curve as short-term and
intermediate-term interest rates did not fall proportionately to
long-term interest rates as the Federal Reserve Board was expected
to continue to raise short-term interest rates. The current
inversion has had as much to do with debt reduction and US Treasury
buybacks as with investor expectations of slower economic growth.
During the last six months, US Treasury bond yields have declined
more than 70 basis points to end the period at 5.78%, their lowest
monthly closing level since May 1999.

Tax-exempt bond yields also have declined in recent months. The
decline has largely been in response to the rally in US Treasury
securities, as well as a continued positive technical supply
environment. States such as California and Maryland have announced
that their large current and anticipated future budget surpluses
will permit the cancellation or postponement of expected bond
issuance. Additionally, some issuers have also initiated tenders to
repurchase existing debt, reducing the supply of tax-exempt bonds in
the secondary market as well. Given the decline in available long-
term US Treasury securities, some investors who need longer maturity
investment vehicles have begun to consider long-term municipal bonds
as potential substitutes. This has further strengthened the overall
positive technical position of the tax-exempt market. During the
last six months, long-term municipal revenue bond yields have
declined nearly 50 basis points to 5.85%, their lowest level since
late August 1999, as measured by the Bond Buyer Revenue Bond Index.

The recent relative underperformance of the municipal bond market in
recent months has been especially disappointing given the strong
technical position the tax-exempt bond market has enjoyed. The
issuance of long-term tax-exempt securities has dramatically
declined. During the last year, almost $200 billion in new long-term
municipal securities was issued, a decline of almost 20% compared to
the same period a year earlier. For the six months ended July 31,
2000, approximately $100 billion in new tax-exempt bonds was
underwritten, a decline of 17% compared to the same period in 1999.


Merrill Lynch Colorado Municipal Bond Fund
July 31, 2000


Although investors received more than $45 billion in coupon
payments, bond maturities and the proceeds from early bond
redemptions during June and July, overall investor demand has
diminished. Long-term municipal bond mutual funds have seen
consistent outflows in recent months as the yields of individual
securities have risen faster than those larger, more diverse mutual
funds. Thus far this year, tax-exempt mutual funds have had net
redemptions of more than $12 billion.

However, the rate at which these redemptions have been occurring has
slowed in recent months. Recent US equity market volatility,
especially in the NASDAQ, has reduced some investor interest in the
stock market. This investor interest, especially earlier this year,
had been siphoning away demand for municipal bonds by retail
investors. Also, the demand from property and casualty companies is
expected to increase in the coming months. These firms are becoming
more profitable after experiencing losses in the past few years
resulting from a series of weather-related natural disasters. Yet as
positive as the tax-exempt bond market's technical environment has
been for much of this year, investor response to the reduction in
both current and future supply of US Treasury bonds has been
overwhelmingly positive and municipal bond yields have
underperformed their taxable counterparts.

Significantly lower municipal bond yields are still likely to
require weaker US employment growth and consumer spending. The
actions taken in recent months by the Federal Reserve Board should
eventually slow US economic growth. Recent declines in US new home
sales are perhaps the first sign that consumer spending is being
slowed by higher interest rates. Until further signs develop, it is
likely that the municipal bond market's current favorable technical
position will dampen significant tax-exempt interest rate volatility
and provide a stable environment for eventual improvement in
municipal bond prices.

Fiscal Year in Review
We entered the fiscal year ended July 31, 2000 in a defensive
position in response to heightened economic growth and inflationary
fears. During the first six months of the fiscal year, we initially
retained our defensive position toward the municipal bond market,
then gradually shifted to a neutral stance. We accomplished this
shift by investing the majority of the Fund's cash reserve and by
purchasing bonds with longer maturities in exchange for bonds with
shorter maturities. Our goal in this shift of strategy was to both
enhance shareholder income and to take advantage of the highest
absolute municipal yields since the spring of 1997. During the last
six months, we maintained our neutral investment position and fully
invested status for the majority of the period. We found it prudent
to maintain this position in anticipation of clearer signs regarding
future economic growth and inflationary expectations. Our shift in
strategy to a neutral stance from a defensive one aided the Fund's
performance during the last six months as municipal yields declined
in conjunction with the US Treasury market.

Colorado municipal bond issuance was comparatively heavy during the
fiscal year, bucking the general trend in the municipal market.
Colorado municipal issuance increased 15% from year-ago levels. The
relatively strong amount of Colorado issuance did provide us with
opportunities to improve the coupon structuring, call protection and
issuer diversification of the Fund. Consequently though, the strong
issuance also outweighed in-state demand at times, causing Colorado
bonds to trade more akin to national levels. We continually monitor
the call protection, credit quality, coupon structuring and
diversification of the Fund in an effort to provide optimal
performance. The decline in new municipal bond issuance can be
traced, in part, to the strong fiscal performance of municipal
entities at most levels of government.

Our strategy throughout the period resulted in above-average total
return performance when compared to the industry average, as
measured by the Lipper Analytical Services, Inc. Colorado Municipal
Debt Funds Average. For the year ended July 31, 2000, the Fund's
Class A, Class B, Class C and Class D Shares returned +2.67%,
+2.15%, +1.94% and +2.57%, respectively, compared to the return of
+1.78% for the Lipper Analytical Services, Inc. Colorado Municipal
Debt Funds Average. (Investment results shown do not reflect sales
charges and would be lower if sales charges were included. Complete
performance information can be found on pages 4 and 5 of this report
to shareholders.) Looking ahead, we intend to remain fully invested
in the municipal market in an effort to enhance shareholder income.
We will also consider taking a more aggressive investment stance
should the economic indicators continue to point to a cooling of
growth and a more stable inflation environment.

In Conclusion
We appreciate your ongoing interest in Merrill Lynch Colorado
Municipal Bond Fund, and we look forward to assisting you with your
financial needs in the months and years ahead.

PERFORMANCE DATA

About Fund Performance

Investors are able to purchase shares of the Fund through the
Merrill Lynch Select Pricing SM System, which offers four pricing
alternatives:

* Class A Shares incur a maximum initial sales charge (front-end
  load) of 4% and bear no ongoing distribution or account maintenance
  fees. Class A Shares are available only to eligible investors.

* Class B Shares are subject to a maximum contingent deferred sales
  charge of 4% if redeemed during the first year, decreasing 1% each
  year thereafter to 0% after the fourth year. In addition, Class B
  Shares are subject to a distribution fee of 0.25% and an account
  maintenance fee of 0.25%. These shares automatically convert to
  Class D Shares after approximately 10 years. (There is no initial
  sales charge for automatic share conversions.)

* Class C Shares are subject to a distribution fee of 0.35% and an
  account maintenance fee of 0.25%. In addition, Class C Shares are
  subject to a 1% contingent deferred sales charge if redeemed within
  one year of purchase.

* Class D Shares incur a maximum initial sales charge of 4% and an
  account maintenance fee of 0.10% (but no distribution fee).

None of the past results shown should be considered a representation
of future performance. Figures shown in the "Recent Performance
Results" and "Average Annual Total Return" tables assume
reinvestment of all dividends and capital gains distributions at net
asset value on the payable date. Investment return and principal
value of shares will fluctuate so that shares, when redeemed, may be
worth more or less than their original cost. Dividends paid to each
class of shares will vary because of the different levels of account
maintenance, distribution and transfer agency fees applicable to
each class, which are deducted from the income available to be paid
to shareholders. The Fund's Investment Adviser voluntarily waived a
portion of its management fee. Without such waiver, the Fund's
performance would have been lower.

Merrill Lynch Colorado Municipal Bond Fund
July 31, 2000


NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:
Merrill Lynch Colorado Municipal Bond Fund (the "Fund") is part of
Merrill Lynch Multi-State Municipal Series Trust (the "Trust"). The
Fund is registered under the Investment Company Act of 1940 as a non-
diversified, open-end management investment company. The Fund's
financial statements are prepared in accordance with accounting
principles generally accepted in the United States of America, which
may require the use of management accruals and estimates. The Fund
offers four classes of shares under the Merrill Lynch Select
Pricing SM System. Shares of Class A and Class D are sold with a
front-end sales charge. Shares of Class B and Class C may be subject
to a contingent deferred sales charge. All classes of shares have
identical voting, dividend, liquidation and other rights and the
same terms and conditions, except that Class B, Class C and Class D
Shares bear certain expenses related to the account maintenance of
such shares, and Class B and Class C Shares also bear certain
expenses related to the distribution of such shares. Each class has
exclusive voting rights with respect to matters relating to its
account maintenance and distribution expenditures. The following is
a summary of significant accounting policies followed by the Fund.

(a) Valuation of investments--Municipal bonds and other portfolio
securities in which the Fund invests are traded primarily in the
over-the-counter municipal bond and money markets and are valued at
the last available bid price in the over-the-counter market or on
the basis of yield equivalents as obtained from one or more dealers
that make markets in the securities. Financial futures contracts and
options thereon, which are traded on exchanges, are valued at their
settlement prices as of the close of such exchanges. Short-term
investments with remaining maturities of sixty days or less are
valued at amortized cost, which approximates market value. Secu-
rities and assets for which market quotations are not readily
available are valued at fair value as determined in good faith by or
under the direction of the Board of Trustees of the Trust, including
valuations furnished by a pricing service retained by the Trust,
which may utilize a matrix system for valuations. The procedures of
the pricing service and its valuations are reviewed by the officers
of the Trust under the general supervision of the Trustees.

(b) Derivative financial instruments--The Fund may engage in various
portfolio investment strategies to increase or decrease the level of
risk to which the Fund is exposed more quickly and efficiently than
transactions in other types of instruments. Losses may arise due to
changes in the value of the contract or if the counterparty does not
perform under the contract.

* Financial futures contracts--The Fund may purchase or sell
financial futures contracts and options on such futures contracts
for the purpose of hedging the market risk on existing securities or
the intended purchase of securities. Futures contracts are contracts
for delayed delivery of securities at a specific future date and at
a specific price or yield. Upon entering into a contract, the Fund
deposits and maintains as collateral such initial margin as required
by the exchange on which the transaction is effected. Pursuant to
the contract, the Fund agrees to receive from or pay to the broker
an amount of cash equal to the daily fluctuation in value of the
contract. Such receipts or payments are known as variation margin
and are recorded by the Fund as unrealized gains or losses. When the
contract is closed, the Fund records a realized gain or loss equal
to the difference between the value of the contract at the time it
was opened and the value at the time it was closed.

(c) 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 substantially all of its
taxable income to its shareholders. Therefore, no Federal income tax
provision is required.

(d) Security transactions and investment income--Security
transactions are recorded on the dates the transactions are entered
into (the trade dates). Interest income is recognized on the accrual
basis. Discounts and market premiums are amortized into interest
income. Realized gains and losses on security transactions are
determined on the identified cost basis.

(e) Prepaid registration feess--Prepaid registration fees are
charged to expense as the related shares are issued.

(f) Dividends and distributions--Dividends from net investment
income are declared daily and paid monthly. Distributions of capital
gains are recorded on the ex-dividend dates.

2. Investment Advisory Agreement and
Transactions with Affiliates:
The Fund has entered into an Investment Advisory Agreement with Fund
Asset Management, L.P. ("FAM"). The general partner of FAM is
Princeton Services, Inc. ("PSI"), an indirect wholly-owned
subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the
limited partner. The Fund has also entered into a Distribution
Agreement and Distribution Plans with FAM Distributors, Inc. ("FAMD"
or the "Distributor"), which is a wholly-owned subsidiary of Merrill
Lynch Group, Inc.

NOTES TO FINANCIAL STATEMENTS (concluded)


FAM is responsible for the management of the Fund's portfolio and
provides the necessary personnel, facilities, equipment and certain
other services necessary to the operations of the Fund. For such
services, the Fund pays a monthly fee based upon the average daily
value of the Fund's net assets at the following annual rates: .55%
of the Fund's average daily net assets not exceeding $500 million;
 .525% of average daily net assets in excess of $500 million but not
exceeding $1 billion; and .50% of average daily net assets in excess
of $1 billion.

For the year ended July 31, 2000, FAM earned fees of $131,853, of
which $71,920 was voluntarily waived.

Pursuant to the Distribution Plans adopted by the Fund in accordance
with Rule 12b-1 under the Investment Company Act of 1940, the Fund
pays the Distributor ongoing account maintenance and distribution
fees. The fees are accrued daily and paid monthly at annual rates
based upon the average daily net assets of the shares as follows:


                                       Account       Distribution
                                   Maintenance Fee        Fee

Class B                                  .25%            .25%
Class C                                  .25%            .35%
Class D                                  .10%             --


Pursuant to a sub-agreement with the Distributor, Merrill Lynch,
Pierce, Fenner & Smith Incorporated ("MLPF&S"), a subsidiary of ML &
Co., also provides account maintenance and distribution services to
the Fund. The ongoing account maintenance fee compensates the
Distributor and MLPF&S for providing account maintenance services to
Class B, Class C and Class D shareholders. The ongoing distribution
fee compensates the Distributor and MLPF&S for providing shareholder
and distribution-related services to Class B and Class C
