Re:  AIM Growth Series
     Definitive Proxy Statement
     Schedule 14A Information
     File No. 002-57526, 811-02699
     CIK No. 0000202032

Dear Mr. O'Connor:

     This letter responds to the Staff's comments on the above-referenced
Preliminary Proxy Statement filed by AIM Growth Series (the "Registrant") on
July 7 , 2009. The filing is in connection with proposed changes to the
sub-classification of each of AIM Independence Now Fund, AIM Independence 2010
Fund, AIM Independence 2020 Fund, AIM Independence 2030 Fund, AIM Independence
2040 Fund, and AIM Independence 2050 Fund (each, a "Fund" and collectively, the
"Funds").

Staff's Comment:

     1.   If the proposal is approved by shareholders will the Funds change from
          a funds of funds structure to a master-feeder structure?

Response:

          No, the Funds will remain as funds of funds. No master-feeder
     structure is contemplated or proposed. The only proposal to be voted on is
     a change to the Funds' sub-classification from diversified to
     non-diversified. If this proposal is approved by shareholders, than the
     names, investment objectives, strategies and risks, underlying funds and
     portfolio manager of the Funds will also change.

Staff's Comment:

     2.   How can certain of the Funds invest 100% of their assets in only one
          underlying fund, AIM Balanced-Risk Allocation Fund ("ABRA")?

Response:

          The Funds are structured as target date funds of funds. Overtime, each
     Fund's portfolio securities will change (allocating portfolio securities to
     affiliated money market funds in addition to ABRA) as each Fund moves
     closer to the target date. The Funds are intended to provide shareholders
     with the ability to invest one time based on each shareholder's individual
     retirement date, and not have to change their investments as they move
     closer to retirement.

Staff's Comment:

     3.   Provide information on the underlying ABRA fund regarding risks,
          derivatives and the use of leverage.

Response:

          Comment complied with. Under "What Other Changes Will Be Made to the
     Funds if Shareholders Approve Changing the Funds' Sub-Classification to
     Non-Diversified," disclosure has been added listing the Funds' new
     principal risks. In addition, disclosure has also been added to this
     section providing a full summary of the primary proposed underlying fund,
     ABRA. The summary includes investment objectives and strategies, including
     disclosure on ABRA's use of derivatives and leverage.

Staff's Comment:

     3.   Can the Funds' underlying funds be changed without a shareholder vote?

Response:

          Yes. Only changes to fundamental investment restrictions, such as
     changing the Funds' sub-classification, requires a vote under these
     circumstances. Changing the underlying funds is not a fundamental
     investment restriction.

Staff's Comment:

     4.   We urge all persons who are responsible for the accuracy and adequacy
          of the disclosure in the filings reviewed by the staff to be certain
          that they have provided all information investors require. Since the
          fund and its management are in possession of all facts relating to the
          fund's disclosure, they are responsible for the accuracy and adequacy
          of the disclosures they have made. In connection with responding to
          our comments, please provide, in writing, a statement from the company
          acknowledging that: the fund is responsible for the adequacy and
          accuracy of the disclosure in the filings; Staff comments or changes
          to disclosure in response to staff comments in the filings reviewed by
          the staff do not foreclose the Commission from taking any action with
          respect to the filing; and the fund may not assert this action as
          defense in any proceeding initiated by the Commission or any person
          under the federal securities laws of the United States.
