From the Chairman

Dear Shareholder: 

Putnam International Voyager Fund's ability to navigate the equity 
markets beyond the borders of the United States for suitable investments 
quite naturally led its managers to Europe during the fund's fiscal year 
ended August 31, 1998. They did not completely ignore Asia or emerging 
markets, but they found little to excite them in these troubled sectors.

Europe's continued economic strength, its vibrant consumer spending, and 
the positive implications of Economic and Monetary Union simply offered 
the best prospects in the search for undervalued stocks of companies 
your fund's managers believe possess reasonably dependable earnings 
growth. 

Asia was represented in the portfolio, of course, mainly by companies 
that report their earnings in U.S. dollars and that occupy niche 
positions in their industries. Your fund's managers continue to view 
Japan with caution.

In the following report, the management team discusses fiscal '98 
strategy and performance and takes a look at prospects for the fiscal 
year just begun.

Respectfully yours,

/S/GEORGE PUTNAM
George Putnam
Chairman of the Trustees
October 21, 1998


Report from the Fund Managers
Omid Kamshad, lead manager
Justin M. Scott
Joshua Byrne
Nigel Hart

During the 12 months ended August 31, 1998, the investment environment 
shifted from a tacit acknowledgment of a regional economic problem in 
Southeast Asia to a worldwide focus on financial and currency market 
instability and uncertainty. Despite this volatile environment, we 
believe that Putnam International Voyager Fund is relatively well 
positioned as it embarks on fiscal 1999. Your fund's portfolio of small 
and midsize companies represents markets and industries we consider are 
able to grow despite the current concerns in the world. 

The Fund's current positioning reflects our disciplined investment 
strategy of seeking companies outside the United States with dependable 
earnings and compelling valuations. For the year ended August 31, 1998, 
the fund had a total return of 11.77% at net asset value (5.36% at 
public offering price). This compares favorably with the -0.14% return 
of the Morgan Stanley Capital International EAFE Index. For more 
performance information, including results for other share classes, 
please turn to page 9. 

* FOCUS REMAINS ON EUROPE, WHERE STRONG CONSUMER SPENDING IS DRIVING 
  ECONOMY

Despite economic contractions in much of the world outside the United 
States, Europe has remained a beacon of solid economic growth. More 
importantly, consumer spending has shown renewed strength and with the 
approach of a single domestic market as a result of Economic and 
Monetary Union (EMU) next year, it looks promising for the future.

Given the declining economic growth rates and lower corporate earnings 
around the world, we focused the portfolio on the relative economic 
strength of the European region, particularly on companies that we 
believe have reasonably dependable earnings growth. As a result, we 
targeted not only classic defensive companies such as utilities -- as 
evidenced by the fund's large weighting in Milan-based electric and gas 
distributor AEM SPA -- but also industries that stand to benefit from 
strong consumer demand. 

This reasoning accounts for many of the fund's positions in 
telecommunications, retail, and media companies. One example is ESAT 
Telecom Group of Ireland. This growing company is one of two Irish 
mobile cellular operators, thus making it well positioned to take 
advantage of nascent cellular subscription growth in Ireland. In our 
opinion, an added bonus of investing in ESAT is that the market has not 
accounted for the potential growth of its land-line business -- which we 
believe could potentially create value for shareholders -- and is 
considering only its cellular business. 

We found Bouygues, a French company involved in construction, 
telecommunications, and media, to be another attractive way to take 
advantage of improving consumer demand and a growing European economy. 
These industries benefit from a benign economic environment, as does 
retailing. Two Italian retailers -- Industrie Natuzzi SPA is a furniture 
manufacturer with sales across Europe and the United States and Marzotto 
& Figli SPA, owner of the well-known Hugo Boss clothing line -- are also 
in the portfolio. While these holdings, along with others discussed in 
this report, were viewed favorably at the end of the period, all are 
subject to review and adjustment in accordance with the fund's 
investment strategy and may vary in the future.

Footnote reads:
*Based on net assets as of 8/31/98. Holdings will vary over time.


* TARGETING EUROPEAN DEMAND FOR EQUITIES

With EMU fast approaching and concern about retirement savings on the 
rise, more investors in Europe are beginning to invest in the region's 
equity markets instead of their traditional asset choice, fixed-income 
securities. This trend has already benefited the large, globally 
oriented asset managers and banks in Europe; however, within the 
universe of stocks we choose from, this trend is more apparent in Swiss 
financial companies and in banks such as the Italian Popolare banks. 

Swiss companies such as Julius Baer Holding AG and Verwaltungs-und 
Privat-Bank AG, as well as Liechtenstein-based Liechtenstein Global 
Trust AG, offer brand-name recognition and solid reputations among 
investors. Additionally, they are not experiencing the fallout from 
emerging markets trading and lending that has affected many larger 
institutions. 

* ASIA REMAINS DISAPPOINTING AS TROUBLES LINGER

Over the past year, the Asian financial crisis -- which was initially 
centered in the emerging Southeast Asian nations and Korea -- spread to 
the financial centers of Hong Kong and Singapore. The high interest 
rates and the credit squeeze that occurred in Hong Kong and Singapore 
then devastated property, finance, and other interest-rate influenced 
companies. 

For the most part, we concentrated on companies that have sales in U.S. 
dollars and that occupy niche positions in their businesses. Some 
examples included Asia Satellite Telecommunications and Smartone 
Telecommunications, of Hong Kong as well as GP Batteries International 
and Venture Manufacturing of Singapore. These companies have the 
advantage of being dollar earners, while a large portion of their costs 
are valued in the depreciated Asian currencies. 

The fund continues to have a relatively small weighting in Japan. Within 
our universe of stocks, we've found it especially difficult to find 
Japanese companies that meet our fundamental stock selection criteria. 
Many of the companies we have reviewed have managements that we believe 
are not focused on raising returns, are not interested in returning 
value to shareholders, and are, in fact, destroying value by investing 
in businesses that can't even earn their cost of capital.

* STRATEGY FOR AN UNCERTAIN WORLD

With no signs of improvement in the Japanese economy and banking system, 
uncertainty in the U.S. market, and the financial contagion affecting 
emerging markets around the world, today's global environment can appear 
to be a disconcerting place for investors. Nevertheless, we remain 
optimistic about our ability to find attractive stocks within the market 
segments in which your fund invests. 

We will continue to look for stocks with the dual attraction of 
dependable earnings growth and undervalued prices, relying on a rigorous 
process of fundamental analysis and a global research team that is 
experienced in the dynamics of small and midsize companies. We believe 
many smaller international companies are currently mispriced and offer 
attractive investment opportunities -- one that your fund is well 
positioned to take advantage of.

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 8/31/98, there is no guarantee the fund will 
continue to hold these securities in the future. International investing 
involves certain risks, such as currency fluctuations, economic 
instability, and political developments, not present with domestic 
investments. This fund invests all or a portion of its assets in small 
to midsize companies. Such investments increase the risk of greater 
price fluctuations.

This section provides information about your fund's performance, which 
should always be considered in light of its investment strategy. Putnam

Past performance is no assurance of future results. Returns for class A 
and class M shares reflect the current maximum initial sales charges of 
5.75% and 3.50% respectively. Class B share returns for the 1-year and 
life-of-fund periods reflect the applicable contingent deferred sales 
charge (CDSC), which is 5% in the first year, declines to 1% in the 
sixth year, and is eliminated thereafter. Returns shown for class B and 
class M shares for periods prior to their inception are derived from the 
historical performance of class A shares, adjusted to reflect both the 
initial sales charge or CDSC, if any, currently applicable to each class 
and in the case of class B and class M shares, the higher operating 
expenses applicable to such shares. All returns assume reinvestment of 
distributions at net asset value. Investment return and principal value 
will fluctuate so that an investor's shares when redeemed may be worth 
more or less than their original cost. Performance data reflects an 
expense limitation currently or previously in effect. Without it, total 
returns would have been lower.

Performance data represent past results, do not reflect future 
performance, and will differ for each share class. Investment returns 
and principal value will fluctuate so that an investor's shares, when 
sold, may be worth more or less than their original cost. See first page 
of performance section for performance calculation method. 

This performance information does not reflect market volatility that may 
have occurred since the date of the information. More recent returns may 
be more or less than those shown.

TERMS AND DEFINITIONS

Total return shows how the value of the fund's shares changed over time, 
assuming you held the shares through the entire period and reinvested 
all distributions in the fund.

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 5.75% maximum sales charge for class A 
shares and 3.50% 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

Europe, Australia and the Far East (EAFE) component of the Morgan 
Stanley Capital International World Index is an unmanaged list of 
international equity securities, excluding U.S., with all values 
expressed in U.S. dollars. The index assumes reinvestment of all 
distributions and interest payments and does not take in account 
brokerage fees or taxes. Securities in the fund do not match those in 
the index and 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.

Report of independent accountants
For the fiscal year ended August 31, 1998

To the Trustees of Putnam Investment Funds and 
Shareholders of Putnam International Voyager Fund 
(a series of Putnam Investment Funds)

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 International Voyager Fund (the "fund") at August 31, 1998, 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 August 
31, 1998 by correspondence with the custodian, provide a reasonable 
basis for the opinion expressed above.

(d) Reflects an expense limitation in effect during the period (Note 2).  As a result of such limitation,
    expense for class A reflect a reduction of approximately $0.08 per share for the year ended
    August 31, 1996.  Expenses for the period ended August 31, 1997 reflect a reduction of $0.02, $0.01,
    and $0.02 for class A, class B, and class M, respectively.

(e) Distributions from net investment income amounted to less than $0.01 per share for class M.

Notes to financial statements
August 31, 1998

Note 1 
Significant accounting policies

Putnam International Voyager Fund (the "fund") is one of a series of 
Putnam Investment Funds (the "Trust") which is registered under the 
Investment Company Act of 1940, as amended, as a diversified, open-ended 
management investment company. The fund seeks long-term capital 
appreciation by investing primarily in equity securities of a number of 
different countries and under normal market conditions it will invest 
primarily in at least three different countries other than the United 
States.

The fund offers class A, class B and class M shares. Class A shares are 
sold with a maximum front-end sales charge of 5.75%. 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 3.50% 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 some 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 
following procedures approved by the Trustees. Foreign securities quoted 
in foreign currencies are translated into U. S. dollars at the current 
exchange rate.

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. 
Collateral for certain tri-party repurchase agreements is held at the 
counterparty's custodian in a segregated account for the benefit of the 
fund and the counterparty. 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. 
Dividend income is recorded on the ex-dividend date except that certain 
dividends from foreign securities are recorded as soon as the fund is 
informed of the ex-dividend date.

E) Foreign currency translation The accounting records of the fund are 
maintained in U.S. dollars. The market value of foreign securities, 
currency holdings, and other assets and liabilities are recorded in the 
books and records of the fund after translation to U.S. dollars based on 
the exchange rates on that day. The cost of each security is determined 
using historical exchange rates. Income and withholding taxes are 
translated at prevailing exchange rates when accrued or incurred. The 
fund does not isolate that portion of realized or unrealized gains or 
losses resulting from changes in the foreign exchange rate on 
investments from fluctuations arising from changes in the market prices 
of the securities. Such gains and losses are included with the net 
realized and unrealized gain or loss on investments. Net realized gains 
and losses on foreign currency transactions represent net exchange gains 
or losses on closed forward currency contracts, disposition of foreign 
currencies and the difference between the amount of investment income 
and foreign withholding taxes recorded on the fund's books and the U.S. 
dollar equivalent amounts actually received or paid. Net unrealized 
appreciation and depreciation of assets and liabilities in foreign 
currencies arise from changes in the value of open forward currency 
contracts and assets and liabilities other than investments at the 
period end, resulting from changes in the exchange rate.

F) Line of credit The fund has entered into a committed line of credit 
with certain banks. This line of credit agreement includes restrictions 
that the fund maintain an asset coverage ratio of at least 300% and 
borrowings must not exceed prospectus limitations. For the year ended 
August 31, 1998, the fund had no borrowings against the line of credit.

G) 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, as amended. Therefore, no 
provision has been made for federal taxes on income, capital gains or 
unrealized appreciation on securities held nor for excise tax on income 
and capital gains.

H) 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 at least 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 temporary and permanent 
differences of losses on wash sale transactions, foreign currency gains 
and losses, post October loss deferrals, organization costs, foreign 
taxes and unrealized gains and losses on passive foreign investment 
companies. 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 August 31, 1998, the fund reclassified $200,308 to decrease 
undistributed net investment income and $3 to decrease paid-in-capital, 
with an increase to accumulated net realized gains of $200,311. The 
calculation of net investment income per share in the financial 
highlights table excludes these adjustments.

I) Expenses of the Trust Expenses directly charged or attributable to 
any fund will be paid from the assets of that fund. Generally, expenses 
of the trust will be allocated among and charged to the assets of each 
fund on a basis that the Trustees deem fair and equitable, which may be 
based on the relative assets of each fund or the nature of the services 
performed and relative applicability to each fund.

J) Unamortized organization expenses Expenses incurred by the fund in 
connection with its organization, its registration with the Securities 
and Exchange Commission and with various states and the initial public 
offering of its shares were $3,662. These expenses are being amortized 
on projected net asset levels over a five-year period. The fund will 
reimburse Putnam Management for the payment of these expenses. 

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: 1.20% of the 
first $500 million of average net assets, 1.10% of the next $500 
million, 1.05% of the next $500 million, 1.00% of the next $5 billion, 
0.975% of the next $5 billion, 0.955% of the next $5 billion, 0.94% of 
the next $5 billion and 0.93% thereafter.

Putnam Management has agreed to limit its compensation (and, to the 
extent necessary, bear other expenses) through August 31, 1998, to the 
extent that expenses of the fund (exclusive of brokerage commissions, 
interest, taxes, deferred organizational and extraordinary expense, 
credits from Putnam Fiduciary Trust Company (PFTC), a subsidiary of 
Putnam Investments, Inc. and payments under the Trust's distribution 
plan) would exceed an annual rate of 1.85% of the fund's average net 
assets.

The fund reimburses Putnam Management an allocated amount 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 reimbursements is determined annually by 
the Trustees.

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

For the year ended August 31, 1998 fund expenses were reduced by $54,171 
under expense offset arrangements with PFTC and brokerage service 
arrangements. 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.

Each Trustee of the fund receives an annual Trustee fee, of which $790 
has been allocated to the fund, 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 has adopted a Trustee Fee Deferral Plan (the "Deferral 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 Deferral Plan.

The fund has adopted an unfunded noncontributory defined benefit pension 
plan (the "Pension Plan") covering all Trustees of the fund who have 
served as Trustee for at least five years. Benefits under the Pension 
Plan are equal to 50% of the Trustee's average total retainer and 
meeting fees for the three years preceding retirement. Pension expense 
for the fund is included in Compensation of Trustees in the Statement of 
operations. Accrued pension liability is included in Payable for 
compensation of Trustees in the Statement of assets and liabilities.

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 to an annual 
rate of 0.25%, 1.00% and 0.75% of the average net assets attributable to 
class A, class B and class M shares respectively.

For the year ended August 31, 1998, Putnam Mutual Funds Corp., acting as 
underwriter received net commissions of $157,672 and $9,402 from the 
sale of class A and class M shares, respectively and received $82,243 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 August 31, 1998, Putnam Mutual Funds 
Corp., acting as underwriter received $63 on class A redemptions.

Note 3 
Purchase and sales of securities

During the year ended August 31, 1998, purchases and sales of investment 
securities other than short-term investments aggregated $198,824,126 and 
$109,841,176 respectively. There were no purchases and sales of U.S. 
government obligations. In determining the net gain or loss on 
securities sold, the cost of securities has been determined on the 
identified cost basis.

Note 4 
Capital shares

At August 31, 1998, there was an unlimited number of shares of 
beneficial interest authorized. Transactions in capital shares were as
