                                                               Chairman

Since the introduction of the first money fund in 1972, the explosive growth of
money funds has gone hand and hand with the growth of the entire mutual fund
industry. Over the last 28 years, millions of investors worldwide have made
money market funds a key part of their investment portfolios. While all
investments involve some degree of risk, money market funds provide investors
with an opportunity to earn current short-term interest rates with a higher
degree of liquidity than most other types of mutual funds.(1)

For those of you who are new shareholders, I would like to extend a warm welcome
to you on behalf of everyone here at SSB Citi. The Smith Barney Municipal Money
Market Fund, Inc. ("Fund") seeks to provide investors with tax-exempt income(2)
from a portfolio of high quality short-term municipal obligations selected for
liquidity and stability of principal. Portfolio managers Joseph P. Deane and
Joseph Benevento use a system of fundamental credit analysis to identify what
they deem to be undervalued sectors and individual securities. They only select
securities of issuers that they believe present minimal credit risk.

When you invest with SSB Citi, you can do so with the confidence that your
interests come first, your investment success is paramount and that the ultimate
in resources is being committed to your financial future. Thank you for
investing with us.

Sincerely,


/s/ Heath B. McLendon

Chairman

Municipal Bond Market and Economic Overview & Outlook

Municipal bonds have been a very simple story throughout 2000. They started at
relatively inexpensive valuations and then rallied. Stable interest rates and a
robust economy with few excesses have helped to paint a bullish picture for
bonds in general, while declining new issue supply may be further bolstering the
municipal bond market. In addition, a vibrant national economy has produced
large cash surpluses in many states and municipalities, causing general
improvement in the credit quality of municipal securities and giving comfort to
many investors regarding the credit worthiness of their securities.

From our point of view, the past few months have been a positive period for the
municipal bond market. As the stock market endured its correction in March and
April 2000, municipal bonds forged ahead slowly but relentlessly. In our view,
the municipal bond markets are in a state of flux that may lead to greater
opportunities. The federal government conducted a buy-back of long-term
government bonds early in 2000, which drove down yields.

The Federal Reserve Board ("Fed") under the leadership of Chairman Alan
Greenspan, raised interest rates incrementally several times in order to cool a
robust U.S. economy. We do not see the Fed raising interest rates again for the
next few months, at least until after Election Day. In an attempt to be
apolitical, the Fed's Board of Governors tends to shy away from such dramatic
moves in an election year, to avoid charges of influencing an election.

The municipal bond market had little reaction to the Fed's decision to keep
interest rates steady or to the Fed's view that risk in the economy is weighted
toward inflation. We believe the bond market is still pricing in another
possible Fed tightening by the end of the year. We expect policy to remain
steady throughout 2000, and we would not be surprised if the Fed were to shift
to a more neutral position before the end of the year. A critical point, which
is often overlooked by many investors, is that the Fed's monetary policy
adjustments take time to be absorbed into the general economy. The Fed has
tightened interest rates 175 basis points(3) from the bottom, and the recent
rallies we have seen are a result of changes enacted six- to twelve-months ago.

Tax-Exempt Money Market Overview and Outlook

During the period, we have seen a decline in short-term municipal bond issuance,
which is due to the record long U.S. economic expansion. With most state and
local governments enjoying balanced budgets or surpluses as a result of
increased tax collections, there has been less need for annual cash-flow
borrowing. Over the last six months, assets in the tax-exempt

----------
(3)   A basis point is 0.01% or one one-hundredth of a percent.


--------------------------------------------------------------------------------
Smith Barney Municipal Money Market Fund, Inc.                                 3

money market fund industry rose by approximately $2.9 billion with total assets
of roughly $217.46 billion as of September 30, 2000.

On May 16, 2000, the Fed increased the federal funds rate ("fed funds rate")(4)
by 50 basis points. However, the supply and demand imbalance in the short-term
municipal bond market put pressures on both the municipal note market and the
Variable Rate Demand Obligation ("VRDO"),(5) and at times, defied rising rates.

During the period, the Bond Buyer One Year Municipal Note Index(6) increased by
approximately 60 basis points to a high of 4.64% in early May of 2000. The
market then looked to June, which is the fiscal year end for most state and
local governments, however less issuance was announced for fiscal year 2001 and
as a result the Bond Buyer One Year Municipal Note Index reacted by falling to a
4.20% by late September.

In the VRDO market, which represents the shorter end of the municipal money
market yield curve,(7) supply and demand imbalances have led to increased
volatility during periods of cyclical cash flows. Over the normal course of the
year, tax-exempt money funds tend to experience large cyclical cash flows. For
example, during the month of April, yields for VRDO's surged as tax-exempt money
funds experienced large redemptions relating to income tax payments. During the
month of July, when tax-exempt money funds experience large inflows from bond
coupon collections and bond calls, yields quickly retreated to levels more
expensive than there taxable equivalents.

Going forward, we believe there may be a greater amount of supply of short-term
municipal securities that became available from decade old municipal bond
issuance. The older issuance are now eligible for investing by money funds by
either pre-refunding(8) or by maturing in 13 months or less.

----------
(4)   Fed funds rate is the interest rate that banks with excess reserves at a
      Federal Reserve district bank charge other banks that need overnight
      loans. The fed funds rate often points to the direction of U.S. interest
      rates.
(5)   VRDO's are demand instruments that usually have an indicated maturity of
      more than one year, but they contain a demand feature that enables the
      holder to redeem the investment on no more than 30 days notice. These
      instruments provide for automatic adjustment of new rates on set dates and
      are generally supported by letters of credit issued by domestic or foreign
      banks.
(6)   The Bond Buyer One Year Municipal Note Index is comprised of ten large
      municipal note issues rated MIG 1 by Moody's Investors Service, Inc. or
      SP+/SP-1 by Standard & Poor's Ratings Service, representing a cross
      section of the municipal note market. Please note an investor cannot
      invest directly in an index.
(7)   The yield curve is the graphical depiction of the relationship between the
      yield on bonds of the same credit quality but different maturities.
(8)   Pre-refunding occurs when an issuer refinances debt through the issuance
      of a new bond deal. The proceeds from the new bond sale are placed in an
      escrow account and are used to retire the debt to the earliest call date.

Investment Strategy

During the period, we increased the Fund's average maturity(9) target to a 65-
to 70-day range. We have extended the Fund's average maturity by buying what we
deem to be high-quality liquid municipal notes.

The Fund's increased average maturity reflects:

      o     A slowdown in economic activity over the near term; and
      o     Less supply of high quality short-term municipal paper.

The record expansion of the U.S. economy has produced budget surpluses for many
state and local governments, which, in turn, has decreased the need for
short-term cash flow financing.

Thank you for your investment in the Smith Barney Municipal Money Market Fund,
Inc. We look forward to continuing to help you pursue your financial goals in
the future.

Sincerely,


/s/ Joseph P. Deane              /s/ Joseph Benevento

Standard & Poor's Ratings Service ("Standard & Poor's") -- Ratings from "AA" to
"BBB" may be modified by the addition of a plus (+) or a minus (-) sign to show
relative standings within the major rating categories.

AAA     -- Debt rated "AAA" have the highest rating assigned by Standard &
           Poor's. Capacity to pay interest and repay principal is extremely
           strong.
AA      -- Debt rated "AA" have a very strong capacity to pay interest and repay
           principal and differ from the highest rated issue only in a small
           degree.
A       -- Debt rated "A" have a strong capacity to pay interest and repay
           principal although it is somewhat more susceptible to the adverse
           effects of changes in circumstances and economic conditions than debt
           in higher rated categories.
BBB     -- Debt rated "BBB" is regarded as having an adequate capacity to pay
           interest and repay principal. Whereas it normally exhibits adequate
           protection parameters, adverse economic conditions or changing
           circumstances are more likely to lead to a weakened capacity to pay
           interest and repay principal for debt in this category than in higher
           rated categories.

Moody's Investors Service Inc. ("Moody's") -- Numerical modifiers 1, 2, and 3
may be applied to each generic rating from "Aa" to "Baa", where 1 is the highest
and 3 the lowest rating within its generic category.

Aaa     -- Bonds that are rated "Aaa" are judged to be of the best quality. They
           carry the smallest degree of investment risk and are generally
           referred to as "gilt edge." Interest payments are protected by a
           large or by an exceptionally stable margin and principal is secure.
           While the various protective elements are likely to change, such
           changes as can be visualized are most unlikely to impair the
           fundamentally strong position of such issues.
Aa      -- Bonds that are rated "Aa" are judged to be of high quality by all
           standards. Together with the Aaa group they comprise what are
           generally known as high grade bonds. They are rated lower than the
           best bonds because margins of protection may not be as large as in
           Aaa securities or fluctuation of protective elements may be of
           greater amplitude or there may be other elements present which make
           the long-term risks appear somewhat larger than in Aaa securities.
A       -- Bonds that are rated "A" possess many favorable investment attributes
           and are to be considered as upper medium grade obligations. Factors
           giving security to principal and interest are considered adequate but
           elements may be present which suggest a susceptibility to impairment
           some time in the future.
Baa     -- Bonds that are rated "Baa" are considered as medium grade
           obligations, i.e., they are neither highly protected nor poorly
           secured. Interest payments and principal security appear adequate for
           the present but certain protective elements may be lacking or may be
           characteristically unreliable over any great length of time. Such
           bonds lack outstanding investment characteristics and in fact have
           speculative characteristics as well.

NR      -- Indicates that the bond is not rated by Standard & Poor's or Moody's.

Short-Term Security Ratings (unaudited)
--------------------------------------------------------------------------------

SP-1    -- Standard & Poor's highest rating indicating very strong or strong
           capacity to pay principal and interest; those issues determined to
           possess overwhelming safety characteristics are denoted with a plus
           (+) sign.
A-1     -- Standard & Poor's highest commercial paper and variable-rate demand
           obligation (VRDO) rating indicating that the degree of safety
           regarding timely payment is either overwhelming or very strong; those
           issues determined to possess overwhelming safety characteristics are
           denoted with a plus (+) sign.
MIG 1   -- Moody's highest rating for short-term municipal obligations.
VMIG 1  -- Moody's highest rating for issues having a demand feature -- VRDO.
VMIG 2  -- Moody's second highest rating for issues having a demand feature --
           VRDO.
P-1     -- Moody's highest rating for commercial paper and for VRDO prior to the
           advent of the VMIG 1 rating.

1. Significant Accounting Policies

Smith Barney Municipal Money Market Fund, Inc. ("Fund"), a Maryland corporation,
is registered under the Investment Company Act of 1940, as amended, as a
diversified, open-end management investment company.

The significant accounting policies consistently followed by the Fund are: (a)
security transactions are accounted for on trade date; (b) the Fund uses the
amortized cost method for valuing investments; accordingly, the cost of
securities plus accreted discount, or minus amortized premium, approximates
value; (c) interest income, adjusted for amortization of premium and accretion
of discount, is recorded on an accrual basis; market discount is recognized upon
the disposition of the security; (d) direct expenses are charged to each class;
management fees and general fund expenses are allocated on the basis of relative
net assets by class; (e) gains or losses on the sale of securities are
calculated by using the specific identification method; (f) dividends and
distributions to shareholders are recorded on the ex-dividend date; (g) the Fund
intends to comply with the applicable provisions of the Internal Revenue Code
pertaining to regulated investment companies and make distributions of taxable
income sufficient to relieve it from substantially all Federal income and excise
taxes; (h) the character of income and gains to be distributed are determined in
accordance with income tax regulations which may differ from generally accepted
accounting principles; and (i) estimates and assumptions are required to be made
regarding assets, liabilities and changes in net assets resulting from
operations when financial statements are prepared. Changes in the economic
environment, financial markets and any other parameters used in determining
these estimates could cause actual results to differ.

2. Exempt-Interest Dividends and Other Distributions

The Fund declares and records a dividend of substantially all of its net
investment income on each business day. Such dividends are paid or reinvested
monthly in Fund shares on the payable date. Furthermore, the Fund intends to
satisfy conditions that will enable interest from municipal securities, which is
exempt from regular Federal income tax and from designated state income taxes,
to retain such status when distributed to its shareholders.

Capital gain distributions, if any, are taxable to shareholders, and are
declared and paid at least annually.

3. Management Agreement and Other Transactions

SSB Citi Fund Management LLC ("SSBC"), a subsidiary of Salomon Smith Barney
Holdings Inc. ("SSBH"), which, in turn is a subsidiary of Citigroup Inc.
("Citigroup"), acts as investment manager to the Fund. The Fund pays SSBC a
management fee calculated at an annual rate of 0.50% on the first $2.5 billion
of the Fund's average daily net assets, 0.475% on the next $2.5 billion, 0.45%
on the next $2.5 billion and 0.40% on average daily net assets in excess of $7.5
billion. This fee is calculated daily and paid monthly.

Citi Fiduciary Trust Company ("CFTC"), another subsidiary of Citigroup, acts as
the Fund's transfer agent and PFPC Global Fund Services ("PFPC") acts as the
Fund's sub-transfer agent. CFTC receives account fees and asset-based fees that
vary according to the account size and type of account. PFPC is responsible for
shareholder recordkeeping and financial processing for all shareholder accounts
and is paid by CFTC. For the six months ended September 30, 2000, the Fund paid
transfer agent fees of $848,984 to CFTC.

Effective June 5, 2000, Salomon Smith Barney Inc. ("SSB"), another subsidiary of
SSBH, became the Fund's distributor replacing CFBDS, Inc. In addition, SSB acts
as the primary broker for the Fund's portfolio agency transactions. Certain
other broker-dealers, continue to sell Fund shares to the public as members of
the selling group.

Pursuant to a Distribution Plan, the Fund pays a distribution fee with respect
to Class A shares calculated at the annual rate of 0.10% of the average daily
net assets of that class.

All officers and one Director of the Fund are employees of SSB.

4. Capital Loss Carryforward

At March 31, 2000, the Fund had, for Federal income tax purposes, approximately
$501,000 of capital loss carryforwards available to offset future capital gains.
To the extent that these carryforward losses are used to offset capital gains,
it is possible that the gains so offset will not be distributed. The amount and
expiration of the carryforwards are indicated below. Expiration occurs on March
31 of the year indicated:

                                   2001         2002         2003         2005

5. Capital Shares

At September 30, 2000, the Fund had ten billion shares of capital stock
authorized with a par value of $0.01 per share.

The Fund has the ability to establish multiple classes of shares. Each share of
a class represents an identical interest in the Fund and has the same rights,
except that each class bears certain expenses specifically related to the
distribution of its shares. Class A and Class Y shares can be purchased directly
by investors. Class C shares are not available for purchase. They represent
previously issued B shares, which were renamed as Class C shares effective
November 7, 1994. Class C shares may only be redeemed or exchanged out of the
Fund.

At September 30, 2000, total paid-in capital amounted to the following for each
class:

                                                Class A               Class Y
