Dear Mr. Cowan:

On behalf of RiverSource Variable Account 10 ("Registrant"), RiverSource Life

received Staff electronic comments regarding Amendment No. 43 and respectfully
responds to the comments herein.

COMMENT 1: Fee Table

     Please list Annual Variable Account Expenses (that apply to everyone) prior
to Optional Rider Fees.

RESPONSE: Complied. Annual Variable Account Expenses will be listed prior to the
Optional Rider Fees.

COMMENT 2: Annual Operating Expenses of the Funds

a. There is a typo - "Minimum and maximum total operating expenses for the
funds(a)"

RESPONSE: Complied. The typo will be corrected and the "(a)" will be put into
superscript mode because it references the footnote (a).

expired on April 30, 2007. Unless the contractual arrangement has been renewed,
please delete the footnote.

RESPONSE: Complied. Footnote 17 has been deleted.

so, please add an AFFE column.

RESPONSE: Complied. Some of the underlying funds are "funds-of-funds" and the
additional AFFE column has been added. Please see the Appendix for complete
table.

*    The Funds provided the information on their expenses and we have not
     independently verified the information.

**   Includes fees and expenses incurred indirectly by the Fund as a result of
     its investment in other investment companies (also referred to as acquired
     funds).

(1)  The Fund's advisor has contractually agreed to waive advisory fees and/or
     reimburse expenses of Series II shares to the extent necessary to limit
     total annual expenses (subject to certain exclusions) of Series II shares
     to 1.45% of average daily net assets. This expense limitation is in effect
     through at least April 30, 2008.

(2)  Through April 30, 2008, the Fund's advisor has contractually agreed to
     waive a portion of its advisory fees. After fee waivers and expense
     reimbursements net expenses would be 1.34% for AIM V.I. Capital Development
     Fund, Series II Shares.

(3)  The figures contained in the table are based on amounts incurred during the
     Fund's most recent fiscal year and have been adjusted, as necessary, to
     reflect current service provider fees. The Fund's Investment Adviser and
     Distributor have contractually agreed to waive advisory fees and reimburse
     the Fund for certain expenses (subject to certain exclusions) through April
     30, 2008. After fee waivers and expense reimbursements net expenses would
     be 0.66% for Columbia High Yield Fund, Variable Series, Class B. There is
     no guarantee that these waivers and/or limitations will continue after
     April 30, 2008.

(4)  Credit Suisse fee waivers are voluntary and may be discontinued at any
     time. After fee waivers and expense reimbursements net expenses would be
     0.95% for Credit Suisse Trust - Commodity Return Strategy Portfolio.

(5)  The Dreyfus Corporation has agreed, until Dec. 31, 2007, to waive receipt
     of its fees and/or assume the expenses of the portfolio so that the net
     expenses (subject to certain exclusions) do not exceed 1.40% for Dreyfus
     Variable Investment Fund International Value Portfolio, Service Shares.

(6)  The Fund's fees and expenses have been restated as if the Fund's new
     investment management and fund administration agreements had been in place
     for the fiscal year ended Dec. 31, 2006. The manager and administrator,
     however, have contractually agreed in advance to waive or limit their
     respective fees so that the increase in investment management and fund
     administration fees paid by the Fund are phased in over a five year period,
     with there being no increase in the rate of such fees for the first year
     ending April 30, 2008. For each of the four years thereafter through April
     30, 2012, the manager and administrator will receive one-fifth of the
     increase in the rate of fees. Beginning May 1, 2012, the full new
     investment management and administration fees will then be in effect.

(7)  The manager has agreed in advance to reduce its fee from assets invested by
     the Fund in a Franklin Templeton money market fund (the acquired fund) to
     the extent that the Fund's fees and expenses are due to those of the
     acquired fund. This reduction is required by the Trust's board of trustees
     and an exemptive order of the Securities and Exchange Commission (SEC).
     After fee reductions net expenses would be 0.93% for FTVIPT Franklin Small
     Cap Value Securities Fund - Class 2.



(8)  "Other expenses" include transfer agency fees and expenses equal on an
     annualized basis to 0.04% of the average daily net assets of the Fund plus
     all other ordinary expenses not detailed in the table above. The Investment
     Adviser has voluntarily agreed to limit "Other expenses" (subject to
     certain exclusions) to the extent that such expenses exceed, on an annual
     basis, 0.044% of the Fund's average daily net assets for Goldman Sachs VIT
     Structured U.S. Equity Fund - Institutional Shares. The Investment Adviser
     may cease or modify the expense limitations at its discretion at anytime.
     If this occurs, other expenses and total annual operating expenses may
     increase without shareholder approval.

(9)  The Fund's management fee as set forth in its Investment Advisory Agreement
     is 0.75% of average daily net assets annually. MFS has agreed in writing to
     reduce its management fee to 0.65% of average daily net assets in excess of
     $3 billion. For the Fund's most recent fiscal year, the effective
     management fee was 0.73% of average daily net assets. This written
     agreement will remain in effect until modified by the Fund's Board of
     Trustees.

(10) Class S shares of the International Portfolio have a redemption fee of
     1.00% for exchanges or redemptions on shares held less than 60 days. The
     redemption fee is paid to the Portfolio.

(11) Neuberger Berman Management Inc. ("NBMI") has undertaken through Dec. 31,
     2010, to waive fees and/or reimburse certain operating expenses, including
     the compensation of NBMI and excluding taxes, interest, extraordinary
     expenses, brokerage commissions and transaction costs, that exceed, in the
     aggregate, 1.17% of the average daily net asset value. The expense
     limitation arrangement for the Portfolio is contractual and any excess
     expenses can be repaid to NBMI within three years of the year incurred,
     provided such recoupment would not cause the Portfolio to exceed its
     respective limitation.

(12) The "Other expenses" in the table are based on, among other things, the
     fees the Fund would have paid if the transfer agent had not waived a
     portion of its fee under a voluntary undertaking to the Fund to limit these
     fees to 0.35% of average daily net assets per fiscal year for all classes.
     That undertaking may be amended or withdrawn at any time. For the Fund's
     fiscal year ended Dec. 31, 2006, the transfer agent fees did not exceed
     this expense limitation. The Manager will waive fees and/or reimburse Fund
     expenses in an amount equal to the indirect management fees incurred
     through the Fund's investment in Oppenheimer Institutional Money Market
     Fund. After fee waivers and expense reimbursements, the net expenses would
     have been 0.88% for Oppenheimer Strategic Bond Fund/VA, Service Shares.

(13) The Fund's expense figures are based on actual expenses for the four month
     period ended Dec. 31, 2006, adjusted to an annual basis.

     RiverSource(R) Variable Portfolio - Small Cap Value Fund.

(15) RiverSource Investments, LLC and its affiliates have contractually agreed
     to waive certain fees and to absorb certain expenses until Dec. 31, 2007,
     unless sooner terminated at the discretion of the Fund's Board. Any amount
     waived will not be reimbursed by the Fund. Under this agreement, net

     RiverSource(R) Variable Portfolio - Small Cap Value Fund.

(16) The fees disclosed reflect gross ratios prior to any voluntary
     waivers/reimbursements of expenses by the adviser. The adviser has
     voluntarily agreed to waive a portion of or all of its management fee
     and/or reimburse expenses to the extent necessary to limit total annual
     operating expenses (subject to certain exclusions). Additionally, the
     distributor has agreed to voluntarily waive a portion of the 12b-1 fee for
     Class II shares. After these fee waivers/reimbursements, net expenses would

     Shares and 1.15% for Van Kampen UIF Mid Cap Growth Portfolio, Class II
     Shares.
