                       Santa Fe, New Mexico 87501


     This Proxy Statement is furnished in connection with the solicitation
of proxies by the Trustees of Thornburg Investment Trust (the "Trust") for
use at the Trust's Special Meeting of Shareholders (the "Meeting") to be
held at 119 East Marcy Street, Suite 202, Santa Fe, New Mexico, on
September 13, 2004 at 10:00 a.m. prevailing Mountain Time, and at any
postponement or adjournment thereof.

     The Trustees have called the Meeting so that shareholders may
consider the re-election of five of the current six Trustees (three of
whom are not "interested persons" of the Trust, as that term is used in
the Investment Company Act of 1940) and to consider the election of three
additional Trustees (none of whom are "interested persons" of the Trust).
Information about the current Trustees and the nominees is provided below.
Shareholders also will consider at the meeting the ratification of
selection of the Trust's independent registered public accounting firm.

      The Proxy Statement and the accompanying Notice of Special Meeting
of Shareholders and form of proxy are being mailed on or about August 4,
2004 to shareholders of record on July 14, 2004.

                           GENERAL MATTERS

     Any person giving a proxy may revoke it at any time prior to its use.
Signed proxies received by the Trust in time for voting and not so revoked
will be voted in accordance with the directions specified in the proxy.
If no instructions are given, the proxy will be voted in favor of all
proposals, and at the discretion of the proxy holders, on any other
matters which may properly come before the Meeting or any postponement or
adjournment thereof.  The Trustees do not know of any actions to be
considered at the Meeting other than those referred to in the Notice of
Special Meeting.

	A majority of the shares of each of the Trust's Funds, entitled to
vote in person or by proxy will be required to constitute a quorum at the
Meeting.  Abstentions and broker non-votes (i.e., proxies from brokers or
nominees indicating that they have not received instructions from the
beneficial owners on an item for which the brokers or nominees do not have
discretionary power to vote) will be treated as present for determining
the existence of a quorum.

	Each nominee to serve as Trustee of the Trust must be elected by a
plurality of the shares of each Fund voted in person or by proxy.
Ratification of the selection of the independent registered public
accounting firm must be approved by a majority of the shares of each Fund
voted in person or by proxy on the matter.  Abstentions and broker non-
votes will not be counted and will have no effect on the result of the
vote.  The Trust expects that broker dealer firms holding shares of the
Funds for their customers will request voting instructions from their
customers.  If these instructions are not received from customers by the
date specified in a request for instructions, the Trust understands that
rules applicable to the broker dealers permit them to vote on the
proposals on behalf of their customers.  Certain broker dealers may
exercise discretion over shares held in their names for which no
instructions are received by voting these shares in the same proportion as
they vote shares for which they received instructions.

     If a quorum is present at the Meeting, but sufficient votes to
approve any of the proposals are not received, the persons named as
proxies may propose one or more adjournments of the Meeting to permit
further solicitation of proxies.  Any such adjournment will be approved if
the votes cast in favor of adjournment exceed the votes cast opposing the
adjournment.  It is anticipated that the persons named as proxies will
vote in favor of any such adjournment.

     Costs of soliciting proxies will be borne by the Trust.  In addition
to solicitation of proxies by use of the mails, some of the officers of
the Trust and persons affiliated with Thornburg Investment Management,
Inc., the investment adviser to the Trust, and Thornburg Securities
Corporation, the distributor of shares of the Trust, may, without separate
remuneration, solicit proxies personally or by telephone, telegram or
facsimile transmission.  The Trust also may retain D. F. King & Co., Inc.,
a professional proxy solicitor, or another professional proxy solicitor to
assist in soliciting proxies.  The solicitor's fee is estimated at $5,000
to $10,000, plus expenses, depending upon the extent of the solicitor's
activities.

     On July 14, 2004, the record date for the determination of
shareholders entitled to vote at the Meeting, there was an aggregate of
397,557,102.565 shares entitled to vote, constituting all of the
outstanding voting securities of the Trust, and the issued and outstanding
shares for each class of each Fund were as follows:

for election as a Trustee of the Trust.  Each nominee has consented to
serve as a Trustee.  Because the Trust does not hold annual meetings, each
Trustee will hold office for an indeterminate period of time, until the
Trustee's retirement or resignation, or until the election and
qualification of a successor Trustee.  Messrs. Thornburg, Ater, Chase,
McMahon and Weyhrauch are currently Trustees, and have served in that
capacity since originally elected or appointed to serve.  Mr. Cutler, Ms.
Dubin and Mr. Van Essen were nominated to fill vacancies created by an
increase to the number of Trustees.  Mr. Cutler, Ms. Dubin and Mr. Van
Essen are standing for election for the first time.  One of the Trust's
current Trustees, Forrest S. Smith, will not stand for election at the
Meeting because of his scheduled retirement on December 31, 2004 in
accordance with the Trust's Bylaws.  Mr. Smith is expected to continue his
service as a Trustee until his scheduled retirement.

     Mr. Cutler, Ms. Dubin and Mr. Van Essen were nominated to stand for
election by the Trust's Nominating Committee, which is comprised of the
Trust's current independent Trustees and which is charged by the Trustees
with the nomination of persons to serve as independent Trustees.  The
functions of the Nominating Committee are described below under the
caption "Committees of the Trustees."  The nominations of Ms. Dubin and
Mr. Van Essen were recommended to the Nominating Committee by independent
Trustees of the Trust, and Mr. Cutler's nomination was recommended by an
interested Trustee who is affiliated with the investment adviser.

     A shareholder using the enclosed Proxy may vote for or against any or
all of the nominees.  IF THE PROXY CARD IS PROPERLY EXECUTED BUT UNMARKED,
IT WILL BE VOTED FOR ALL OF THE NOMINEES.  The eight nominees receiving
the highest number of votes cast at the meeting shall be elected, provided
that a quorum is present.  Each of the nominees has consented to be named
as a nominee in the Proxy Statement.  The Trustees have no reason to
believe that any of the nominees will become unavailable for election as a
Trustee, but if that should occur before the Meeting, proxies will be
voted for persons recommended by the Trustees, in the discretion of the
individuals holding the proxies.

(1)   Certain persons may be considered under the Investment Company Act
      of 1940 to be "interested" persons of the Trust, because of their
      relationship to the investment adviser or the distributor of the
      Funds' shares, or for other reasons.  Mr. Thornburg and Mr. McMahon
      are considered interested persons, as explained in notes (3) and
      (4), below.  The other persons standing for election are not
      considered "interested," and for purposes of this Proxy Statement
      are identified as "independent" Trustees.

(2)   The Thornburg Funds complex is comprised of 12 separate investment
      portfolios or "Funds," each of which is a series of Thornburg
      Investment Trust (the "Trust").  Until June 21, 2004, two of the
      Funds, Thornburg Limited Term Municipal Fund and Thornburg
      California Limited Term Municipal Fund, were organized as series of
      Thornburg Limited Term Municipal Fund, Inc., a separate registered
      investment company (the "Company").  On June 21, 2004, the two
      series of the Company were reorganized as Funds of the Trust.  Mr.
      Thornburg, Mr. Chase and Mr. Cutler were Directors of the Company.

(3)   Mr. Thornburg is considered an "interested" Trustee under the
      Investment Company Act of 1940 because he is a director and
      controlling shareholder of Thornburg Investment Management, Inc.,
      the investment adviser to the 12 Funds of the Trust, and is sole
      director and controlling shareholder of Thornburg Securities
      Corporation, the distributor for shares of the Trust.

(4)   Mr. McMahon is considered an "interested" Trustee under the
      Investment Company Act of 1940 because he is the president of
      Thornburg Investment Management, Inc.

(5)   Mr. Smith is retiring on December 31, 2004 and is not standing for
      reelection.

Meetings of the Trustees
- ------------------------

     The Trustees generally meet at least four times in each calendar
year, to review the operations of the Funds, oversee the services provided
by the Funds' investment adviser, review and consider compliance issues
respecting the Funds, and to consider other topics pertaining to the
Funds' management.  The Trustees met four times in the fiscal year that
ended September 30, 2003.  Each Trustee then in office attended at least
75% of the aggregate of the total number of meetings conducted by the
Trustees and the total number of meetings held by the committees on which
the Trustee served.  The Trust does not currently have a policy respecting
Trustees' attendance of annual shareholders meetings, because the Trust
does not hold annual meetings.

Compensation of Trustees
- ------------------------

     The Trustees affiliated with the investment adviser serve without any
compensation from the Trust.  Commencing with the second calendar quarter
of 2004, the Trust pays each Trustee who is not an employee of the
investment adviser or an affiliated person an annual fee of $20,000 plus
$1,000 for each meeting of the Trustees attended by the Trustee.  In
addition, the Trust pays a $4,000 annual stipend to each member of the
audit committee, payable in quarterly installments, pays an annual stipend
of $2,000 to the audit committee chairman, and pays each member of the
audit committee a fee of $1,000 per meeting attended in excess of four per
year.  The Trust reimburses each Trustee for travel and out-of-pocket
expenses incurred by the Trustee in connection with attending meetings.
The Trust does not pay retirement or pension benefits.

     The Trust paid fees to the Trustees during the year ended September
30, 2003 as follows:


                         Pension or
                         Retirement      Estimated      Total

(1) The Fund Complex formerly included Thornburg Limited Term Municipal
    Fund, Inc. (the "Company") and the Trust.  The Company comprised two
    separate series, "Thornburg Limited Term Municipal Fund National
    Portfolio" and "Thornburg Limited Term Municipal Fund California
    Portfolio," until June 21, 2004, when those two funds were reorganized
    as Funds of the Trust.  Mr. Chase was both a Director of the Company
    and a Trustee of the Trust.


Interests of Trustees or Nominees in Certain Transactions
- ---------------------------------------------------------

     Eliot Cutler, who is a nominee for election as an independent
Trustee, was president of Capitol Ventures, Inc., which was a general
partner of Lease Fund Partners.  Until September 30, 2002, Lease Fund
Partners was entitled to receive from Thornburg Investment Management,
Inc. ("Thornburg"), a share of the revenue Thornburg received from
Thornburg Limited Term Municipal Fund, Inc. (the "Company"), a separate
investment company with two series or "funds" as to which Thornburg was
the investment adviser.  Lease Fund Partners also was entitled to receive
from Thornburg Securities Corporation ("TSC"), the distributor of the
Funds, a share of the revenue TSC received from the Company.  In the
fiscal year ended September 30, 2002, Mr. Cutler and family members
received an aggregate of $7,656 in payments under this arrangement.  On
September 30, 2002, Lease Fund Partners relinquished its interest in these
revenues in exchange for a consideration of approximately $1,000,000, and
the interest of Mr. Cutler and his family in the consideration received
was $62,500.  On June 21, 2004, the two series of the Company were
reorganized as Funds of Thornburg Investment Trust.

Committees of the Trustees
- --------------------------

Audit Committee
- ---------------

     The Trustees have an Audit Committee, which is currently comprised of
the four Trustees who are not interested persons, Mr. Smith (Chairman),
Mr. Ater, Mr. Weyhrauch and Mr. Chase.  The Audit Committee discharges its
duties in accordance with an audit committee charter, which provides that
the Committee will (i) evaluate performance of the Trust's auditors, (ii)
review planning, scope and staffing of audits, (iii) review results of
audits with the auditors, (iv) receive and review reports from auditors
respecting auditor independence, and (v) require the Trust's legal counsel
to report to the Committee any matter which may have a significant effect
on any of the Trust's financial statements.  The Audit Committee is
responsible for the selection of the Funds' independent registered public
accounting firm which audits the annual financial statements of each Fund.
The Audit Committee evaluates the independence of the independent
registered public accounting firm based on information provided by the
accounting firm and the investment adviser, and meets with representatives
of the independent registered public accounting firm and the investment
adviser to discuss, consider and review matters related to the Funds'
accounting and financial reports.  A copy of the Trust's Audit Committee
Charter accompanies this Proxy Statement as Appendix A.  The Committee
held five meetings in the Trust's fiscal year ended September 30, 2003.
Additional information about the Trust's independent registered public
accounting firm and the compensation of the independent registered public
accounting firm are provided below under the caption "PROPOSAL TWO."

Nominating Committee
- --------------------

     The Trustees have a Nominating Committee, which is comprised of the
four Trustees who are not interested persons, Mr. Chase, Mr. Ater, Mr.
Smith and Mr. Weyhrauch.  The Nominating Committee discharges its duties
in accordance with a nominating committee charter, which provides that the
Committee will select and nominate individuals for election as Trustees of
the Trust who are not interested persons.

     In selecting and nominating individuals to serve as independent
Trustees, the Committee places primary emphasis on these criteria: (i)
judgment, character, expertise, skills and knowledge useful to the
oversight of the Trust's business and activities; (ii) diversity of
viewpoints, backgrounds, experiences and other characteristics; (iii)
business, educational or other relevant experience; and (iv) the extent to
which the interplay of a candidate's expertise, skills, knowledge and
experience with that of other Trustees will comprise a board of Trustees
that is effective, collegial and responsive to the needs of the Trust and
its shareholders.  The Nominating Committee conducted no meetings in the
Trust's fiscal year ended September 30, 2003.

     Where there is a vacancy among the Trustees, the Nominating Committee
receives and reviews information on potential nominees.  To date, the
Committee has been able to identify, and expects in the future to be able
to identify, from its own resources (including recommendations from
members of the Committee) qualified candidates for evaluation as potential
nominees.  The Nominating Committee also is authorized to consider
candidates recommended by shareholders in accordance with the Trust's
Procedure for Shareholder Communications to Trustees.  The Committee will
evaluate candidates recommended by shareholders using the same criteria as
other candidates identified to the Committee.  See the information
respecting shareholder communications to Trustees below, under the caption
"ADDITIONAL INFORMATION ABOUT THE TRUST-Communications With the Trustees."
A copy of the Trust's Nominating Committee Charter accompanies this Proxy
Statement as Appendix B.

     The Audit Committee and Trustees have selected the firm of
PricewaterhouseCoopers LLP ("PWC") as the independent registered public
accounting firm for the fiscal year ended June 30, 2004 for Thornburg
Limited Term Municipal Fund, Thornburg California Limited Term Municipal
Fund and Thornburg New York Intermediate Municipal Fund, and for the
fiscal year ending September 30, 2004 for Thornburg Intermediate Municipal
Fund, Thornburg New Mexico Intermediate Municipal Fund, Thornburg Florida
Intermediate Municipal Fund, Thornburg Limited Term U.S. Government Fund,
Thornburg Limited Term Income Fund, Thornburg Value Fund, Thornburg
International Value Fund, Thornburg Core Growth Fund and Thornburg

determined to change the fiscal year of Thornburg Limited Term Municipal
Fund, Thornburg California Limited Term Municipal Fund and Thornburg New
York Intermediate Municipal Fund to a year ending September 30, effective
September 30, 2004.  Accordingly, the Audit Committee and the Trustees
have selected PWC to serve as independent registered public accounting
firm for the short fiscal year beginning July 1, 2004 and ending September
30, 2004.  At the Meeting, the shareholders will consider ratification of
the selection of PricewaterhouseCoopers LLP as independent registered
public accounting firm for the short fiscal year ending September 30, 2004
for each of the Funds.  Representatives of PWC are not expected to be
present at the Meeting, but will have the opportunity to make a statement
if they wish, and will be available should any matter arise requiring
their presence.

Audit Fees
- ----------

     The aggregate fees billed to Thornburg Investment Trust in each of
the last two fiscal years for the audit of the Trust's financial
statements and for services that are normally provided by PWC in
connection with statutory and regulatory filings or requirements for those
fiscal years are set out below.  In addition, the table below displays the
aggregate fees billed to Thornburg Limited Term Municipal Fund, Inc. (the
"Company") for the audit of the Company's financial statements and
services described in the preceding sentence for the Company's two most
recent fiscal years.  On June 21, 2004, the Company's two series,
Thornburg Limited Term Municipal Fund and Thornburg California Limited
Term Municipal Fund, were reorganized as Funds of Thornburg Investment
Trust.

(1)  For the periods reflected above, nine Funds of the Trust had a fiscal
     year ending September 30, and one Fund of the Trust had a fiscal year
     ending June 30.  Consequently, information for the two most recent
     fiscal years ended September 30, 2002 and September 2003 includes
     fees of $10,000 billed in each of those years for the one June 30
     year end Fund, but those fees related in each case to the fiscal year
     ending on the preceding June 30.

     The fees billed to Thornburg Investment Trust by PWC in each of the
last two fiscal years for assurance and related services that are

consents respecting the commencement of operations by a new Fund and the
creation and issuance of a new class of shares by some Funds of the Trust.

  Fund, Inc.                               $5,500              $7,000

The tax fees billed to the Trust and the Company in each of the last two
fiscal years were primarily for tax return preparation.

All Other Fees
- --------------

     PWC did not bill Thornburg Investment Trust or the Company for other
products or services, other than described above, for the two most recent
fiscal years of Thornburg Investment Trust or the Company.

     PWC performs no services for the investment adviser, the Funds'
principal underwriter or any other person controlling, controlled by, or
under common control with the investment adviser, which provides ongoing
services to the Funds, except that PWC has provided to the investment
adviser, Thornburg Investment Management, Inc., in the periods described
above, attestation of its investment performance presentations.  The fees
billed by PWC for these services were $32,750 and $32,500 for the fiscal
years ended September 30, 2002 and September 30, 2003, respectively.

The Audit Committee has determined that PWC's performance of the described
services for the investment adviser is compatible with PWC's independence
in its audit of the Funds.

Audit Committee Pre-Approval Policies and Procedures
- ----------------------------------------------------

     The Trustees have adopted a Procedure for Shareholder Communications
to Trustees, which provides for receipt, collection and forwarding of
communications addressed to one or more of the Trustees, or pertaining to
proposals of any candidate for nomination as a Trustee.  Shareholders may
send communications to any one or more of the Trustees pertaining to the
business of the Trust, by United States Mail or courier delivery,
addressed to the Trust or Trustees at 119 East Marcy Street, Santa Fe, New
Mexico 87501, Attn:  Trustee Communications.  The communication must
include the name and address of the shareholder, the approximate number
and class of shares held by the shareholder in each Fund to which the

review of any shareholder communications by officers of the Trust or the

Trustees to whom the communication should be directed, (iii) if the
communication pertains to a proposed candidate for nomination as a

otherwise relates to improper or irrelevant topics, or is properly
directed to other persons.

     Any written communications transmitted as described above, which are
addressed to one or more specific Trustees by name, are forwarded to the

independent accountants, to enhance the Committee's knowledge of relevant
current and prospective business/financial issues.

     The Committee shall meet at least three times each year.  Additional
meetings shall be scheduled as considered necessary by the Committee or

     The Trust's independent accountants are directed to communicate with
the Committee as requested by the Committee or its chairman, and are

auditors believe should be brought to the Committee's attention.

     It is not the duty of the Committee to plan or conduct audits or to

of the Committee to assure compliance with applicable laws and
regulations.

     The Committee, through its chairman, shall report to the Trustees
periodically as deemed necessary by the Trustees or the chairman, or as
otherwise required herein.  The Committee will prepare and retain minutes

     The Committee shall have the sole authority to select, evaluate,
appoint and replace the Trust's independent accountants (subject to

advance all audit and non-audit services performed by the independent
accountants, and the fees and terms for delivery of those services.

     The Committee shall have the authority, to the extent it deems it
necessary or appropriate, to retain special legal, accounting, or other
consultants to advise the Committee.  The Trust shall compensate the
independent accountants and advisers retained by the Committee, as
determined by the Committee.

     The Committee may form and delegate authority to subcommittees,
comprised of one or more members of the Committee, as necessary or
appropriate.  Each subcommittee may have such portion or all of the
authority of the Committee, as determined by the Committee; and the
Committee's authority to delegate described in this paragraph includes,
but is not limited to, the pre-approval of any or all engagements of
independent accountants.

     The Committee may require any officer or employee of the Trust or the
Trust's independent accountants or outside counsel to meet with the
Committee or to meet with any members or subcommittee of the Committee, or
with consultants to the Committee.
