LETTER FROM THE CHAIRMAN

Fellow Shareholder,

During  the 12  months  ended  August  31,  2003,  the  yields  of money  market
instruments plumbed new depths,  which translated into very modest total returns
for the Vanguard Money Market Funds.

These returns were nevertheless significantly better than the average returns of
our funds' peer groups,  as  illustrated by the adjacent  table.  The table also
displays each fund's annualized yield as of August 31.

One  easy-to-overlook  achievement in this low-return  environment is the funds'
continued  success in meeting their  mandates to preserve  principal  (the share
price of each  fund  held  steady at $1,  as is  expected  but not  guaranteed),
provide liquidity, and generate superior relative returns.

DISMAL AT THE START, THE STOCK MARKET PERKED UP

A slumping economy,  weak corporate profits, and growing  geopolitical  tensions
weighed  heavily on the stock  market as our fiscal year began,  and a two-month
rally  from  mid-October  quickly  ran  out of  steam.  However,  following  the
successful  conclusion of major combat  operations in Iraq, a distinctly  upbeat
mood began to permeate the market

                                                                               1



place. Stock prices began to rebound across capitalizations and industry sectors
in response to solid  corporate  earnings  announcements  and a slew of positive
economic reports.

The U.S.  stock  market,  as measured by the Wilshire  5000 Total Market  Index,
returned 14.9% for the fiscal year. Technology and other growth-oriented stocks,
which had sustained  massive  losses  during the past few years,  were among the
most  impressive  gainers.  The market's  smaller stocks outpaced larger issues,
demonstrating investors' renewed appetite for risk.

U.S. investors were rewarded with good returns in many international  markets as
well,  although stock  performance was only part of the story.  The weakening of
the U.S.  dollar by almost 10% relative to the euro and Japanese yen transformed
results   that  were   mediocre   by   local-currency   standards   into  strong
dollar-denominated returns.

INTEREST RATES FELL THROUGH MUCH OF
THE FISCAL YEAR, THEN BOUNCED BACK A BIT

In the bond  market,  the  fiscal  year was marked by two  distinctly  different
phases.  Prior to  mid-June,  the  lethargic  economy  and  ongoing  flight from
equities to bonds drove the prices of bonds higher and their yields  lower.  The
yield of the  benchmark  10-year U.S.  Treasury note dropped to a 45-year low of
3.11% on June 13. After that point,  however,  longer- term interest  rates rose
rapidly,  with the yield of the 10-year  T-note  standing at 4.46% on August 31.
For the 12 months,  the Lehman  Brothers  Aggregate Bond Index, a measure of the
taxable investment-grade bond market, provided a total return of 4.4%.

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

Short-term  interest  rates  generally  declined  for the 12  months,  but  rose
somewhat toward the end. In an effort to add fuel to the economic recovery,  the
Federal  Reserve Board  trimmed its target for the federal funds rate  twice--in
November  2002 and June  2003--by a total of 75 basis  points  (0.75  percentage
point). The rate stood at 1.00% at the fiscal year-end. The yield of the 3-month
Treasury bill,  which  typically lags Fed moves,  began the fiscal year at 1.67%
and closed at 0.97% after falling to a low of 0.81% in mid-June.

ALREADY LOW INTEREST RATES HEADED EVEN LOWER

The result of the Federal Reserve's long campaign to reduce short-term  interest
rates has been most visible in the returns of money market instruments. When the
fiscal year opened,  the  annualized  yields of the Vanguard  Money Market Funds
hovered  between 1% and 2%, lows uncharted  since the  introduction of the money
market mutual fund in the 1970s.

In the ensuing 12 months,  as the Fed trimmed  its target for  short-term  rates
from 1.75% to 1.00%,  money market yields moved even lower.  The Investor Shares
of Vanguard  Prime Money Market Fund,  our oldest and largest money market fund,
returned  1.1%--their  lowest  fiscal-year  return  since the  fund's  June 1975
inception.

The Institutional  Shares of Vanguard Prime Money Market Fund returned 1.3%, our
money market funds' best result.  Institutional  investors'  significant account
balances create economies of scale that reduce fund operating  costs,  enhancing
returns.  (The Institutional  Shares,  which require a minimum investment of $10
million,  carried an expense ratio of 0.10% in fiscal 2003; the Investor Shares,
with a minimum  investment  requirement  of just $3,000,  operated at an expense
ratio of 0.32%.)

Vanguard Treasury Money Market Fund's 1.0% return reflected its exclusive focus
on T-bills, which are generally the lowest yielding,

                                                                               3


but highest  quality,  money market  securities.  Vanguard  Federal Money Market
Fund,  which  seeks to enhance  the  returns  of an  all-Treasury  portfolio  by
investing in short-term securities issued by federal agencies, returned 1.1%.

IN THE LONG RUN, COSTS ARE KEY

Although  skilled  portfolio  management  is critical to  obtaining  the largest
possible share of the returns available in the money market, the rewards of good
management can be realized only if operating expenses are low, too. The Vanguard
Money Market  Funds boast some of the lowest  operating  costs in the  industry,
which is why each fund  outperformed  its respective peer group average in 2003.
For example,  the 1.1% return of the  Investor  Shares of the Prime Money Market
Fund  was  almost  twice  the  0.6%  return  of  the  average  competitor.   Not
coincidentally,   our  fund  boasted  an  expense  advantage  over  the  average
competitor of 0.6 percentage points.

The role of costs in money market fund  returns  becomes  especially  clear over
longer time  periods.  The table below shows the average  annual  returns of the
Vanguard  Money  Market  Funds and those of their peer  groups for the ten years
ended August 31, 2003. It also displays how equal  investments  in our funds and
their  average  competitors  would have grown.  In each case,  the Vanguard fund
produced a higher total return--and  created more wealth for  shareholders--than
its average peer.

TIMELESS PRINCIPLES AMID PERSISTENT CHANGE

Since early 2000, the financial markets have followed trajectories unfamiliar to
most market participants. Stocks endured one of the longest and deepest declines
in financial  history,  while  interest rates crept down to levels not seen in a
generation or more. In recent months, the cycles seemed to turn: Stocks produced
exceptional returns, and interest rates began to rise.

These events are in fact no more than extreme  manifestations of the uncertainty
that always rules the  financial  markets.  We believe that the best approach to
this  uncertainty  is the  faithful  use  of  time-tested  principles:  balance,
diversification,  and low costs. A balance among stocks, bonds, and money market
funds allows you to pursue growth of capital while securing some protection from
the markets' inevitable downturns.  Due to their stability and liquidity,  money
market  funds can play a special  role as a  repository  for  money  needed  for
short-term  goals. In any asset mix, low costs are key to ensuring that you reap
the maximum possible share of the financial markets' rewards.

We thank you for entrusting your assets to us.



Sincerely,

REPORT FROM THE ADVISOR

The yields of the Vanguard Money Market Funds declined  during the past year, as
the Federal Reserve Board  continued to trim its target for short-term  interest
rates.  Lower yields  translated  into modest  returns for our four  portfolios,
ranging  from  1.0% for  Vanguard  Treasury  Money  Market  Fund to 1.3% for the
Institutional Shares of Vanguard Prime Money Market Fund. Each fund outperformed
its average peer.

THE INVESTMENT ENVIRONMENT

During the first half of the fiscal year,  a weak stock market and  geopolitical
uncertainties restrained economic growth. But in March, once the war in Iraq was
under way,  business  and consumer  activity  improved.  In the second  calendar
quarter,  real  (inflation-adjusted)  gross  domestic  product  (GDP) grew at an
annualized rate of 3.3%, well above market expectations.  Signs of rising demand
from U.S.  businesses included a surge in imported goods (up 8.8%) and a decline
in business  inventories.  Stronger  demand  bodes well for  continued  economic
growth in the second half of the calendar year.

================================================================================
INVESTMENT  PHILOSOPHY

THE FUNDS REFLECT A BELIEF THAT THE HIGHEST LEVEL OF CURRENT  INCOME  CONSISTENT
WITH CAPITAL  PRESERVATION AND LIQUIDITY CAN BE PROVIDED BY HOLDING HIGH-QUALITY
MONEY  MARKET  INSTRUMENTS  ISSUED  BY  FINANCIAL  INSTITUTIONAL,   NONFINANCIAL
CORPORATIONS, THE U.S. GOVERNMENT, AND FEDERAL AGENCIES.
================================================================================

The economy has benefited from  stimulative  fiscal and monetary  policies.  For
example,  the tax reductions  recently signed into law were front-loaded in ways
that should provide a significant near-term boost to GDP. The extra pocket money
should  lead to an  increase  in  consumer  spending,  which has  propped  up an
otherwise  anemic  economy the past few years.  Also driving  gains has been the
availability of inexpensive  credit,  especially in the mortgage and home equity
markets.

The Federal  Reserve  Board has tried to  accelerate  the economic  expansion as
well. In June the Fed lowered the target federal funds rate again, the 13th time
since January 2001,  bringing it to  1.00%--the  lowest level in 45 years.  This
most recent cut brought the reduction over the

6


Vanguard  Money Market  Funds'  fiscal year to 75 basis points (0.75  percentage
point).  The Fed's  actions,  while  aimed at  helping  the  economy,  have also
highlighted  the risks  implied by  unusually  low  interest  rates,  namely the
possibility of deflation--a general decline in prices.

At the end of our fiscal  year,  one of the most visible  economic  concerns was
weakness in the labor market.  While the  unemployment  rate was 6.1% in August,
down from its June peak of 6.4%,  the labor  market  remained  weak.  Over time,
rising  unemployment  could  create  a drag on the  economy,  although  it isn't
unusual to see such a trend in the early  stages of a  recovery,  as  businesses
struggle to maintain their productive capacity in an uncertain environment.

OUR INVESTMENT APPROACH

During the year,  we  extended  the  duration  of the money  market  portfolios,
anticipating that short-term rates would remain low for an extended period. This
positioning  allowed us to capture the higher interest rates that were available
farther out on the yield curve, enhancing the funds' performance.

In the Federal Money Market Fund, we took  advantage of periods when the federal
funds rate was higher than the Fed's  target  rate  through  our  management  of
overnight repurchase agreements.  This strategy allowed us to capture the higher
rates  of  return  that  are  periodically   available  on  short-term   funding
obligations.

In both the Federal and Prime Money Market  Funds,  we increased our exposure to
Treasury bills,  and reduced our exposure to agency  securities,  when the yield
differential  between  these  two  groups  narrowed  to a  point  at  which  the
credit-risk-free  T-bills became a more attractive option. Toward the end of our
fiscal year, revelations concerning the accounting practices at the Federal Home
Loan Mortgage  Corporation  (FHLMC), and the subsequent departure of a number of
senior  FHLMC  executives,  led to a rise in the  relative  yields of all agency
securities.  In keeping with our  conservative  investment  philosophy,  we took
steps to reduce both the Federal and Prime Money Market Funds' exposure to FHLMC
securities  and increase our  weighting in Treasury  securities.  This  decision
caused  us to  give up a  modest  amount  of  yield,  but we  believe  that  the
precautionary steps were warranted.

                                                                               7


After  allowing the maturity of the Prime Money Market Fund to increase  earlier
this  year,  we've  begun to let it drift  lower in  anticipation  that the past
year's  efforts at fiscal and monetary  stimulus may be sufficient to revive the
economy.  Absent  an  extraordinary  advance  in  near-term  economic  activity,
however, we expect short-term money market rates to remain at low levels for the
rest of the year.

Whether  rates rise or fall further,  we're  confident in our ability to provide
strong relative  returns,  in large part because of our low operating costs. Low
costs put us in the enviable  position of being able to provide  portfolios with
higher-than-average credit quality and higher-than-average net yield.

GLOSSARY OF INVESTMENT TERMS
================================================================================
AVERAGE  MATURITY.  The average length of time until  securities  held by a fund
reach maturity and are repaid.
- --------------------------------------------------------------------------------
AVERAGE QUALITY.  An indicator of credit risk, this figure is the average of the
ratings  assigned to a fund's holdings by credit-rating  agencies.  The agencies
make  their  judgment  after   appraising  an  issuer's   ability  to  meet  its
obligations.  Quality is graded on a scale,  with Aaa or AAA indicating the most
creditworthy  issuers.  U.S.  Treasury  securities  are  considered  to have the
highest credit quality.
- --------------------------------------------------------------------------------
EXPENSE  RATIO.  The  percentage of a fund's  average net assets used to pay its
annual  administrative  and advisory  expenses.  These expenses  directly reduce
returns to investors.
- --------------------------------------------------------------------------------
YIELD.  A  snapshot  of a fund's  interest  income.  The yield,  expressed  as a
percentage  of the fund's net asset  value,  is based on income  earned over the
past seven days and is annualized, or projected forward for the coming year.

PERFORMANCE SUMMARIES                                            AS OF 8/31/2003

All of the returns in this report  represent past  performance,  which cannot be
used to predict future returns that may be achieved by the funds.  An investment
in a money  market fund is not  insured or  guaranteed  by the  Federal  Deposit
Insurance Corporation or any other government agency. Although the funds seek to
preserve the value of your  investment  at $1 per share,  it is possible to lose
money by investing in the funds.  The returns  shown do not reflect taxes that a
shareholder would pay on fund distributions or on the redemption of fund shares.
The  annualized  yields  shown  reflect the  current  earnings of the funds more
closely than do the average annual returns shown.

ABOUT YOUR FUND EXPENSES

All mutual funds have  operating  expenses.  These  expenses  include  costs for
portfolio  management,  administrative  services,  and shareholder reports (like
this one), among others.  Operating  expenses,  which are deducted from a fund's
gross  income,  directly  reduce  the  investment  return of the fund.  A fund's
expenses are expressed as a percentage  of its net assets.  This figure is known
as the expense ratio.

A HYPOTHETICAL EXAMPLE

We believe it is  important  for you to  understand  the impact of costs on your
investment.  The following  example  illustrates  the costs that you would incur
over a 12-month  period if you  invested  $10,000 in the fund,  using the fund's
actual return and operating  expenses for the fiscal year ended August 31, 2003.
For comparative  purposes, we also list the average expense ratio for the fund's
peer group, which is derived from data provided by Lipper Inc.

The funds do not charge transaction fees; these results apply whether or not you
redeemed your  investment at the end of the given period.  Your actual costs may
have been higher or lower,  depending on the amount of your  investment and your
holding period. Peer-group ratios capture data through year-end 2002.

You can find more  information  about a fund's expense ratio,  including  annual
expense ratios for the past five years, in the Financial  Statements  section of
this  report.  For  additional  information  on  operating  expenses  and  other
shareholder  costs,  please  refer  to the  fund's  prospectus.  The  prospectus
presents  hypothetical  shareholder costs over various time periods based upon a
$10,000 investment and a return of 5% a year. This standardized  example,  which
appears in all mutual fund  prospectuses,  may be useful to you in comparing the
costs of investing in different funds.

FINANCIAL STATEMENTS                                             AS OF 8/31/2003

STATEMENT OF NET ASSETS

This Statement  provides a detailed list of each fund's holdings on the last day
of the reporting period, including each security's maturity date, coupon rate or
yield to maturity at the time of  purchase,  and  statement-date  market  value.
Securities  are grouped and  subtotaled by type of instrument  (U.S.  government
obligations,  commercial paper, certificates of deposit, etc.). Other assets are
added to, and liabilities are subtracted from, the value of Total Investments to
calculate  the  fund's  Net  Assets.  Finally,  Net  Assets  are  divided by the
outstanding  shares of the fund to arrive at its share price, or Net Asset Value
(NAV) Per Share.  Each fund's  objective  is to maintain a constant NAV of $1.00
per share.

At the end of the  Statement  of Net Assets of each fund,  you will find a table
displaying the composition of the fund's net assets. Virtually the entire amount
of net assets  consists of Paid-in  Capital  (money  invested by  shareholders).
Undistributed Net Investment Income is usually zero because the fund distributes
its net income to shareholders as a dividend each day, and Accumulated  Realized
Gains (Losses) are very small because the fund seldom  realizes any  significant
gains or losses on sales of securities.

STATEMENT OF OPERATIONS

This Statement  shows  interest  income earned by each fund during the reporting
period,  and details the operating expenses charged to each class of its shares.
These expenses  directly reduce the amount of investment income available to pay
to  shareholders  as income  dividends.  This  Statement also shows any Net Gain
(Loss)  realized on the sale of  investments,  and any  Unrealized  Appreciation
(Depreciation)  of  investments  during  the  period.  For money  market  funds,
Realized Net Gain (Loss) should always be minimal,  and Unrealized  Appreciation
(Depreciation) should be zero.

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how the fund's total net assets changed during the two most
recent reporting periods. The Operations section summarizes information detailed
in the  Statement  of  Operations.  Because the fund  distributes  its income to
shareholders  each day,  the amounts of  Dividends  from Net  Investment  Income
generally equal the net income earned as shown under the Operations section. The
Capital Share Transactions section shows the amount shareholders invested in the
fund,  either by  purchasing  shares or by  reinvesting  distributions,  and the
amounts redeemed.  Dividends and Capital Share Transactions are shown separately
for each class of shares.

FINANCIAL HIGHLIGHTS

Each fund's  objective  is to  maintain a constant  net asset value of $1.00 per
share by  distributing  all of the fund's  net  investment  income and  avoiding
capital gains or losses.  The financial  highlights table summarizes each fund's
investment  results and  distributions  to shareholders on a per-share basis for
each class of shares.  The table also  presents  the Total  Return and shows net
investment income and expenses as percentages of average net assets.  These data
will help you assess the variability of net income returns from year to year and
how much it costs to operate the fund.

NOTES TO FINANCIAL STATEMENTS

Vanguard Money Market Funds comprise the Prime Money Market Fund,  Federal Money
Market Fund, Treasury Money Market Fund, and Admiral Treasury Money Market Fund,
each of which is  registered  under  the  Investment  Company  Act of 1940 as an
open-end investment company, or mutual fund. The Prime Money Market Fund invests
in short-term  debt  instruments  of companies  primarily  operating in specific
industries,  particularly  financial  services;  the issuers'  abilities to meet
their  obligations may be affected by economic  developments in such industries.
The Federal Money Market Fund invests in short-term debt  instruments  issued by
the U.S.  government or its agencies and  instrumentalities.  The Treasury Money
Market Fund and the Admiral Treasury Money Market Fund invest in short-term debt
instruments backed by the full faith and credit of the U.S. government.

The Prime Money  Market Fund offers two classes of shares,  Investor  Shares and
Institutional  Shares.  Investor  Shares are available to any investor who meets
the fund's minimum purchase requirements.  Institutional Shares are designed for
investors who meet certain  administrative  and servicing  criteria and invest a
minimum of $10 million. The Federal, Treasury, and Admiral Treasury Money Market
Funds each offer only Investor Shares.

                                                                              37

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

A. The following  significant  accounting policies conform to generally accepted
accounting  principles for U.S. mutual funds. The funds consistently follow such
policies in preparing their financial statements.

1.  SECURITY   VALUATION:   Securities  are  valued  at  amortized  cost,  which
approximates market value.

2. REPURCHASE AGREEMENTS: The Prime Money Market and Federal Money Market Funds,
along with other members of The Vanguard  Group,  may transfer  uninvested  cash
balances to a pooled cash account,  which is invested in  repurchase  agreements
secured by U.S. government  securities.  These funds may also invest directly in
repurchase   agreements.   Securities   pledged  as  collateral  for  repurchase
agreements  are held by a  custodian  bank  until the  agreements  mature.  Each
agreement  requires  that the market value of the  collateral  be  sufficient to
cover  payments of interest and principal;  however,  in the event of default or
bankruptcy by the other party to the agreement,  retention of the collateral may
be subject to legal proceedings.

3. FEDERAL INCOME TAXES: Each fund intends to continue to qualify as a regulated
investment  company and distribute all of its taxable  income.  Accordingly,  no
provision for federal income taxes is required in the financial statements.

4.  DISTRIBUTIONS:  Dividends from net investment  income are declared daily and
paid on the first business day of the following month.

5. OTHER: Security transactions are accounted for on the date the securities are
purchased or sold.  Costs used to determine  realized gains (losses) on the sale
of investment  securities are those of the specific  securities sold.  Discounts
and premiums are accreted and amortized,  respectively,  to interest income over
the lives of the respective securities.

Each class of shares has equal  rights as to assets and  earnings,  except  that
each  class  separately  bears  certain   class-specific   expenses  related  to
maintenance of shareholder  accounts  (included in Management and Administrative
expenses),  shareholder  reporting,  and  proxies.  Marketing  and  distribution
expenses are allocated to each class of shares based on a method approved by the
board of trustees.  Income,  other  non-class-specific  expenses,  and gains and
losses  on  investments  are  allocated  to each  class of  shares  based on its
relative net assets.

B.  The  Vanguard  Group  furnishes  at  cost  investment  advisory,   corporate
management, administrative,  shareholder accounting, marketing, and distribution
services.  The costs of such  services are  allocated to each fund under methods
approved  by the board of  trustees.  Each fund has  committed  to provide up to
0.40% of its assets in capital  contributions  to Vanguard.  At August 31, 2003,
the funds had contributed capital to Vanguard (included in Other Assets) of:

REPORT OF INDEPENDENT AUDITORS

To the Shareholders and Trustees of Vanguard Money Market Funds:

In our  opinion,  the  accompanying  statements  of net assets  and the  related
statements  of  operations  and of  changes  in net  assets  and  the  financial
highlights present fairly, in all material  respects,  the financial position of
Prime Money Market Fund,  Federal Money Market Fund,  Treasury Money Market Fund
and Admiral Treasury Money Market Fund (hereafter referred to as the "Funds") at
August  31,  2003,  the  results of each of their  operations  for the year then
ended,  the changes in each of their net assets for each of the two years in the
period  then  ended  and  the  financial  highlights  for  each  of the  periods
indicated,  in conformity with accounting  principles  generally accepted in the
United States of America.  These financial  statements and financial  highlights
(hereafter referred to as "financial  statements") are the responsibility of the
Funds'  management;  our  responsibility  is to  express  an  opinion  on  these
financial  statements  based on our  audits.  We  conducted  our audits of these
financial statements in accordance with auditing standards generally accepted in
the United  States of America,  which require that we plan and perform the audit
to obtain reasonable  assurance about whether the financial  statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and  disclosures in the financial  statements,  assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall  financial  statement  presentation.  We believe that our
audits,  which  included  confirmation  of  securities  at  August  31,  2003 by
correspondence with the custodian, provide a reasonable basis for our opinion.
