From the Chairman

Dear Shareholder:

Fiscal 1996, the 12 months ended September 30, was a year of 
contrasts for Putnam American Government Income Fund. The year began 
amid one of the most vibrant bond market advances in recent times. 
By its midpoint, the rally suddenly became a retreat as investors, 
reading stronger-than-expected economic numbers as a presage to a 
pickup in inflation, sent the bond markets tumbling. Interest rates, 
moving inversely to bond prices, bounded sharply higher. 

During the fiscal year's second half, the market settled down 
somewhat, although investors remained generally aloof, waiting to 
discern a definite trend in interest rates. Fund Manager Michael 
Martino, focusing on yield, trimmed back on Treasury securities in 
favor of mortgage-backed issues.

As the fund begins a new fiscal year, Mike believes rates may trend 
lower over the next few months as economic growth moderates. He 
discusses the fund's performance and prospects in the report that 
follows. 

Respectfully yours, 

/S/ George Putnam

George Putnam

Chairman of the Trustees

November 20, 1996



Report from the Fund Manager
Michael Martino

Putnam American Government Income Fund's 1996 fiscal year, which 
ended on September 30, encompassed two periods of pronounced market 
strength -- the first three months and the final month of the year -
- - with alternating periods of turbulence and stability in between. 
Fiscal 1996 began with the same bond market strength that capped off 
a successful calendar 1995. 

Beginning in January, however, and extending through the first four 
months of calendar 1996, interest rates rose dramatically across the 
spectrum of bond maturities. From May to the end of the fiscal year, 
rates stayed in a relatively tight range of 6.7% to 7.2% for the 30-
year Treasury bond and were accompanied by a somewhat surprising 
lack of activity by the Federal Reserve Board. In fact, the bond 
market's September advance was in response to the Fed's decision to 
keep the target for short-term bank-lending rates unchanged at 5.25% 
- -- a level it established last January -- based on evidence of a 
slowing economy.

For the year as a whole, your fund posted solid total returns 
relative to many other U.S. government securities funds, while 
continuing to focus on strategies for seeking high current income. 
(Please refer to the tables on pages 8 and 9 for complete 
performance and dividend information.) 

*ACTIVE MANAGEMENT OF INTEREST-RATE EXPOSURE WAS KEY TO PERIOD'S 
RESULTS

The key determinant of your fund's performance over the year was 
active management of the portfolio's duration. Duration is the 
principal indicator of interest-rate sensitivity for a given 
portfolio of bonds. It is measured in years. The longer the 
duration, the more sensitive a portfolio is to a given change in 
rates. When rates are falling, as was the case during the first 
three months and the final month of the fiscal year, bond prices 
rise, and a relatively long portfolio duration enables the fund to 
capture a greater portion of that price appreciation. 

When interest rates rise, however, a long duration has the opposite 
effect, causing the portfolio's value to decline more rapidly for a 
given change in rates. Consequently, over the course of the fiscal 
year, we adjusted the fund's duration from approximately 6 years 
during the first 3 months to under 4.5 years at the period's 
midpoint, back out to nearly 6 years at the period's end. 

*GINNIE MAES BOLSTER PERFORMANCE DURING PERIOD OF BROAD MARKET 
WEAKNESS

Lack of momentum in the U.S. Treasury market during much of the 
fund's fiscal year led bond investors to look elsewhere for yield. 
This, in turn, led to an increased demand for mortgage-backed 
securities at a time when the supply of such bonds was relatively 
low. Premium mortgages -- those offering higher income streams than 
the current yields of similar bonds -- outperformed Treasuries as 
rising interest rates allayed prepayment fears.* All told, your 
fund's considerable exposure to Ginnie Maes worked in its favor, 
although it would have benefited more from a greater allocation to 
premium mortgages.

Duration                     6.1            4.4             5.8

Footnote reads:
This chart depicts the fund's average effective maturity and 
portfolio duration measures at the beginning, middle, and end of the 
1996 fiscal year.  Average effective maturity and duration are 
derived from calculations that incorporate assumptions about 
prepayment rates and cash flows of mortgage-backed securities. 
Measures of effective maturity, duration, and the assumptions on 
which they are based will vary over time.


As we approached the end of the fiscal year, Ginnie Maes and other 
mortgage-backed securities appeared to be fully valued relative to 
Treasuries. Therefore, during the September market rally, when we 
extended the fund's duration, we accomplished this by adding 
intermediate and long-term Treasuries -- not mortgage-backed 
securities. Mortgage-backed securities, nevertheless, still 
represent a substantial portion of your fund's portfolio, accounting 
for approximately 45% of net assets at the end of the period. As for 
Treasuries, your fund ended the year with nearly 54% of its net 
assets allocated to Treasuries versus 46% at the beginning. 

*SLOWER GROWTH MAY PROVIDE CONTINUED SUPPORT FOR BONDS

When the Federal Reserve Board last met in September, we believe it 
made the right decision in taking no action on short-term interest 
rates. The Fed's attempts to control inflation by adjusting monetary 
policy, thus far, have been successful. Indeed, we believe the 
economy's growth rate is likely to moderate, perhaps moving back 
toward a 2% annual level. It is possible that inflation may exhibit 
some near-term signs of accelerating, given the rising price of oil 
and the trend toward increasing labor costs. We believe, however, 
that should economic growth slow in the months ahead, inflation is 
likely to remain well behaved. 

Although we cannot provide assurances, if our expectations for the 
economy prove correct, then the current favorable environment for 
bonds may persist for some time. Given such a scenario, we would 
likely maintain a portfolio that is moderately long in duration in 
order to position the fund to participate should market strength 
continue. 

Footnote reads: 
*Mortgage-backed securities are subject to prepayment risk, which is 
the risk that an investor's principal will be returned in full at 
some point prior to the security's stated maturity date. Such prepayment 
may cause an investor's actual rate of return to differ from the expected 
rate of return. Prepayment risk is greatest when interest rates are falling, 
since mortgage holders rush to refinance, forcing retirement of the bonds 
that back their existing mortgages.

COMPARATIVE PORTFOLIO ALLOCATIONS*]

                         9/30/95            9/30/96
U.S. Treasury
securities                46.1%              53.8%

Mortgage-backed
securities                49.8%              45.1%

Cash and short-
term investments           6.9%               0.2%

Footnote reads:
*Based on total net assets as of the indicated date. The allocations 
to mortgage-backed securities are primarily concentrated in bonds 
issued by the Government National Mortgage Association (Ginnie Mae).  
Allocations will vary over time.

While mortgage-backed securities typically provide a higher yield 
than Treasuries of comparable maturity, they generally underperform 
during periods of market strength. Consequently, we are comfortable 
with the fund's current allocation to mortgage-backed securities 
and, consistent with our view of the broader market, do not plan to 
increase the weighting at this time. We believe that intermediate 
and long-term Treasuries represent better value at current yield 
levels and plan, for now, to focus a greater share of our investment 
activities on that segment of the government securities market. 

The views expressed here are exclusively those of Putnam Management. 
They are not meant as investment advice. Although the described 
holdings were viewed favorably as of 9/30/96, there is no guarantee 
the fund will continue to hold these securities in the future. While 
U.S. government backing of individual securities does not insure 
your principal, which will fluctuate with market conditions, it does 
guarantee that the fund's government-backed holdings will make 
timely payments of interest and principal. The fund may invest in 
securities other than those issued or backed by the full faith and 
credit of the U.S. government.

TERMS AND DEFINITIONS

Class A shares are generally subject to an initial sales charge. 

Class B shares may be subject to a sales charge upon redemption.

Class M shares have a lower initial sales charge and a higher 12b-1 
fee than class A shares and no sales charge on redemption.

Net asset value (NAV) is the value of all your fund's assets, minus 
any liabilities, divided by the number of outstanding shares, not 
including any initial or contingent deferred sales charge. 

Public offering price (POP) is the price of a mutual fund share plus 
the maximum sales charge levied at the time of purchase. POP 
performance figures shown here assume the maximum 4.75% sales charge 
for class A shares and 3.25% for class M shares.

Contingent deferred sales charge (CDSC) is a charge applied at the 
time of the redemption of class B shares and assumes redemption at 
the end of the period. Your fund's CDSC declines from a 5% maximum 
during the first year to 1% during the sixth year. After the sixth 
year, the CDSC no longer applies.

COMPARATIVE BENCHMARKS

Lehman Brothers Intermediate Treasury Index is an unmanaged list of 
Treasury bonds; it is used as a general gauge of the market for 
intermediate-term fixed-income securities. The index does not take 
into account brokerage commissions or other costs, may include bonds 
different from those in the fund, and may pose different risks than 
the fund. Securities indexes assume reinvestment of all 
distributions and interest payments, and the performance of the fund 
will differ. It is not possible to invest directly in an index.

Consumer Price Index (CPI) is a commonly used measure of inflation; 
it does not represent an investment return.



A Putnam perspective on risk and reward

You've probably been told how important it is to understand the 
relationship between an investment's potential rewards and its 
accompanying risks. Given the cautionary nature of such 
instructions, it may take most investors a while to realize that 
risk has a positive side.

Every risk signals a potential reward. Selecting only those 
investments that offer the greatest degree of security generally 
leads to only modest rewards. Furthermore, even insured or 
guaranteed investments may be subject to changes in their rates of 
return or, in some cases, in their principal values. Experienced 
investors know that no investment is truly risk free and are 
therefore willing to take on some measure of risk in order to 
increase their potential gains.

The greater the risk, the greater the potential reward. Accepting an 
appropriate level of investment risk can give you a better chance of 
outpacing inflation over time and seeking to maximize your 
investment's return. How much risk? Your financial advisor's 
feedback and your time horizon can make all the difference in 
determining how much risk is compatible with your investment goals 
and your peace of mind.

*FITTING YOUR FUND SELECTION TO YOUR RISK TOLERANCE

How do you find the right balance between investment risks and their 
potential rewards? It's helpful to understand the types of risks 
that can apply to different types of investments, and to look at 
your own portfolio with this perspective.

For short-term goals, your first priority may be managing market 
risk. Longer-term investors may be more concerned with inflation 
risk. And all income-oriented investors should consider interest-
rate, credit, and prepayment risks carefully. Within each of 
Putnam's four investment categories, you can select funds with 
differing levels of risk and reward potential to customize your 
portfolio.

This list covers only the most general types of risks; however, each 
investment will also have its own specific risks. You will find a 
more detailed discussion of these risk considerations in each fund's 
prospectus.

*A RUNDOWN OF RISK TYPES

MARKET RISK Most important for stock funds, but relevant to all 
funds, this is a measure of how sensitive a fund's holdings are to 
changes in general market conditions. Remember, though, that 
securities that lose value quickly in market declines may also show 
the strongest gains in more favorable environments.

INTEREST-RATE RISK Since bond prices fall as interest rates rise, 
this type of risk is a particular concern for fixed-income inves-
tors. However, interest-rate increases can also have a substantial 
negative effect on the stock market.

INFLATION RISK If your investments cannot keep pace with inflation, 
your money will begin to lose its purchasing power. Stock 
investments are generally considered among the best ways of 
addressing inflation risk over the long term.

CREDIT AND PREPAYMENT RISK Credit risk is the concern that the 
security's issuer will not be able to meet its payment, while 
prepayment risk involves the premature payoff of a loan, with a 
resulting loss of interest income. Professional management and in-
depth research are invaluable in managing both these risks.

LIQUIDITY RISK Not all investments can be readily converted into 
cash at their perceived market values. Liquidity risk can affect the 
price of securities held in the fund's portfolio and, thus, the 
fund's share prices.

Report of independent accountants

To the Trustees and Shareholders of 
Putnam American Government Income Fund 

In our opinion, the accompanying statement of assets and 
liabilities, including the portfolio of investments owned, 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 Putnam American Government Income Fund 
(the "fund") at September 30, 1996, and the results of its 
operations, the changes in its net assets and the financial 
highlights for the periods indicated, in conformity with generally 
accepted accounting principles. These financial statements and 
financial highlights (hereafter referred to as "financial 
statements") are the responsibility of the fund's 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 generally accepted auditing 
standards 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 investments owned at September 30, 1996 by 
correspondence with the custodian, provide a reasonable basis for 
the opinion expressed above.

Notes to financial statements
September 30, 1996

Note 1
Significant accounting policies

The fund is registered under the Investment Company Act of 1940, as 
amended, as a diversified, open-end management investment company. 
The fund seeks high current income, with preservation of capital as 
its secondary objective. 

The fund offers class A, class B and class M shares. Class A shares 
are sold with a maximum front-end sales charge of 4.75%. Class B 
shares, which convert to class A shares after approximately eight 
years, do not pay a front-end sales charge, but pay a higher ongoing 
distribution fee than class A shares, and are subject to a 
contingent deferred sales charge, if those shares are redeemed 
within six years of purchase. Class M shares are sold with a maximum 
front-end sales charge of 3.25% and pay an ongoing distribution fee 
that is lower than class B shares and higher than class A shares. 

Expenses of the fund are borne pro-rata by the holders of each class 
of shares, except that each class bears expenses unique to that 
class (including the distribution fees applicable to such class). 
Each class votes as a class only with respect to its own 
distribution plan or other matters on which a class vote is required 
by law or determined by the Trustees. Shares of each class would 
receive their pro-rata share of the net assets of the fund, if the 
fund were liquidated. In addition, the Trustees declare separate 
dividends on each class of shares.

The following is a summary of significant accounting policies 
consistently followed by the fund in the preparation of its 
financial statements. The preparation of financial statements is in 
conformity with generally accepted accounting principles and 
requires management to make estimates and assumptions that affect 
the reported amounts of assets and liabilities. Actual results could 
differ from those estimates.

A) Security valuation Investments for which market quotations are 
readily available are stated at market value, which is determined 
using the last reported sale price, or, if no sales are reported--as 
in the case of most securities traded over-the-counter--the last 
reported bid price. Short-term investments having remaining 
maturities of 60 days or less are stated at amortized cost, which 
approximates market value, and other investments are stated at fair 
value following procedures approved by the Trustees. 

B) Joint trading account Pursuant to an exemptive order issued by 
the Securities and Exchange Commission, the fund may transfer 
uninvested cash balances into a joint trading account along with the 
cash of other registered investment companies and certain other 
accounts managed by Putnam Investment Management, Inc. ("Putnam 
Management"), the fund's Manager, a wholly-owned subsidiary of 
Putnam Investments, Inc.. These balances may be invested in one or 
more repurchase agreements and/or short-term money market 
instruments. 

C) Repurchase agreements The fund, or any joint trading account, 
through its custodian, receives delivery of the underlying 
securities, the market value of which at the time of purchase is 
required to be in an amount at least equal to the resale price, 
including accrued interest. Putnam Management is responsible for 
determining that the value of these underlying securities is at all 
times at least equal to the resale price, including accrued 
interest.

D) Security transactions and related investment income Security 
transactions are accounted for on the trade date (date the order to 
buy or sell is executed). Interest income is recorded on the accrual 
basis. 

E) Federal taxes It is the policy of the fund to distribute all of 
its taxable income within the prescribed time and otherwise comply 
with the provisions of the Internal Revenue Code applicable to 
regulated investment companies. It is also the intention of the fund 
to distribute an amount sufficient to avoid imposition of any excise 
tax under Section 4982 of the Internal Revenue Code of 1986. 
Therefore, no provision has been made for federal taxes on income, 
capital gains or unrealized appreciation on securities held and for 
excise tax on income and capital gains.

At September 30, 1996, the fund had a capital loss carryover of 
approximately $1,447,359,000 available to offset future capital 
gains, if any. The amount of the carryover and the expiration dates 
are:
       Loss Carryover            Expiration
       --------------      --------------------
       $1,137,954,000       September 30, 1998
       $   45,648,000       September 30, 2001
       $    7,767,000       September 30, 2002
       $  255,990,000       September 30, 2003

F) Distributions to shareholders Distributions to shareholders from 
net investment income are recorded by the fund on the ex-dividend 
date. Capital gain distributions, if any, are recorded on the ex-
dividend date and paid annually. The amount and character of income 
and gains to be distributed are determined in accordance with income 
tax regulations which may differ from generally accepted accounting 
principles. These differences include treatment of losses on wash 
sale transactions, utilization of a capital loss carryover and 
paydown gains and losses on mortgage backed securities. 
Reclassifications are made to the fund's capital accounts to reflect 
income and gains available for distribution (or available capital 
loss carryovers) under income tax regulations. For the year ended 
September 30, 1996, the fund reclassified $10,233,831 to increase 
undistributed net investment income and $10,672,332 to decrease 
paid-in-capital, with an increase to accumulated net realized loss 
on investments of $438,501. The calculation of net investment income 
per share in the financial highlights table excludes these 
adjustments.

Note 2
Management fee, administrative 
services and other transactions

Compensation of Putnam Management, for management and investment 
advisory services is paid quarterly based on the average net assets 
of the fund. Such fee is based on the following annual rates: 0.60% 
of the first $500 million of average net assets, 0.50% of the next 
$1 billion, 0.45% of the next $1 billion, 0.40% of the next $4.5 
billion, 0.375% of the next $2.5 billion, and 0.35% of any excess 
over $9.5 billion, subject, under current law, to reduction in any 
year by the amount of certain brokerage commissions and fees (less 
expenses) received by affiliates of Putnam Management on the fund's 
portfolio transactions. 

The fund reimburses Putnam Management for the compensation and 
related expenses of certain officers of the fund and their staff who 
provide administrative services to the fund. The aggregate amount of 
all such reimbrsements is determined annually by the Trustees. 

Custodial functions for the fund's assets are provided by Putnam 
Fiduciary Trust Company (PFTC), a wholly-owned subsidiary of Putnam 
Investments, Inc. Investor servicing agent functions are provided by 
Putnam Investor Services, a division of PFTC. 

For the year ended September 30, 1996, fund expenses were reduced by 
$965,207 under expense offset arrangements with PFTC. Investor 
servicing and custodian fees reported in the Statement of operations 
exclude these credits. The fund could have invested a portion of the 
assets utilized in connection with the expense offset arrangements 
in an income producing asset if it had not entered into such 
arrangements.

Trustees of the fund receive an annual Trustees fee of $2,690 and an 
additional fee for each Trustee's meeting attended. Trustees who are 
not interested persons of Putnam Management and who serve on 
committees of the Trustees receive additional fees for attendance at 
certain committee meetings.

The fund adopted a Trustee Fee Deferral Plan (the "Plan") which 
allows the Trustees to defer the receipt of all or a portion of 
Trustees Fees payable on or after July 1, 1995. The deferred fees 
remain in the fund and are invested in certain Putnam funds until 
distribution in accordance with the Plan.

The fund has adopted distribution plans (the "Plans") with respect 
to its class A, class B and class M shares pursuant to Rule 12b-1 
under the Investment Company Act of 1940. The purpose of the Plans 
is to compensate Putnam Mutual Funds Corp., a wholly-owned 
subsidiary of Putnam Investments Inc., for services provided and 
expenses incurred by it in distributing shares of the fund. The 
Plans provide for payments by the fund to Putnam Mutual Funds Corp. 
at an annual rate up to 0.35%, 1.00% and 1.00% of the average net 
assets attributable to class A, class B and class M shares, 
respectively. The Trustees have approved payment by the fund at an 
annual rate of 0.25%, 1.00% and 0.50% of the average net assets 
attributable to class A, class B and class M shares, respectively.

For the year ended September 30, 1996, Putnam Mutual Funds Corp., 
acting as underwriter received net commissions of $109,577 and 
$1,307 from the sale of class A and class M shares, respectively and 
$40,354 in contingent deferred sales charges from redemptions of 
class B shares. A deferred sales charge of up to 1% is assessed on 
certain redemptions of class A shares. For the year ended September 
30, 1996, Putnam Mutual Funds Corp., acting as underwriter received 
$10,430 on class A redemptions.

Note 3
Purchase and sales of securities

During the year ended September 30, 1996, purchases and sales of 
U.S. government and agency obligations other than short-term 
investments aggregated $4,660,803,437 and $4,907,799,639, 
respectively. In determining the net gain or loss on securities 
sold, the cost of securities has been determined on the identified 
cost basis.
