	FILED PURSUANT TO RULE 13d-1(b) or 13d-2(b)



	Pursuant to the instructions in Item 7 of Schedule 13G,
Fidelity Management & Research Company ("Fidelity"), 82
Devonshire Street, Boston, Massachusetts 02109, a wholly-
owned subsidiary of FMR LLC and an investment adviser
registered under Section 203 of the Investment Advisers Act
of 1940, is the beneficial owner of 3,668,808 shares or 3.215%
of the Common Stock outstanding of Radioshack Corporation
("the Company") as a result of acting as investment adviser to

the Investment Company Act of 1940. The number of shares
of Common Stock of Radioshack Corporation owned by the
investment companies at December 31, 2010 included 23,508
shares of Common Stock resulting from the assumed
conversion of $570,000 principal amount of RADIOSHACK
CONV2.5 8/1/13 144A (41.2414 shares of Common Stock for
each $1,000 principal amount of debenture).

	Edward C. Johnson 3d and FMR LLC, through its
control of Fidelity, and the funds each has sole power to
dispose of the 3,668,808 shares owned by the Funds.

	Members of the family of Edward C. Johnson 3d,

The Johnson family group and all other Series B shareholders
have entered into a shareholders' voting agreement under
which all Series B voting common shares will be voted in
accordance with the majority vote of Series B voting common
shares.  Accordingly, through their ownership of voting
common shares and the execution of the shareholders' voting
agreement, members of the Johnson family may be deemed,
under the Investment Company Act of 1940, to form a
controlling group with respect to FMR LLC.

	Neither FMR LLC nor Edward C. Johnson 3d,
Chairman of FMR LLC, has the sole power to vote or direct
the voting of the shares owned directly by the Fidelity Funds,
which power resides with the Funds' Boards of Trustees.
Fidelity carries out the voting of the shares under written
guidelines established by the Funds' Boards of Trustees.

	Pyramis Global Advisors, LLC ("PGALLC"), 900
Salem Street, Smithfield, Rhode Island, 02917, an indirect
wholly-owned subsidiary of FMR LLC and an investment
adviser registered under Section 203 of the Investment
Advisers Act of 1940, is the beneficial owner of 205,384
shares or 0.180% of the outstanding Common Stock of
Radioshack Corporation as a result of its serving as investment
adviser to institutional accounts, non-U.S. mutual funds, or
investment companies registered under Section 8 of the
Investment Company Act of 1940 owning such shares. The
number of shares of Common Stock of Radioshack
Corporation owned by the institutional account(s) at
December 31, 2010 included 171,564 shares of Common
Stock resulting from the assumed conversion of $4,160,000
principal amount of RADIOSHACK CONV2.5 8/1/13 144A
(41.2414 shares of Common Stock for each $1,000 principal
amount of debenture).

	Edward C. Johnson 3d and FMR LLC, through its
control of PGALLC, each has sole dispositive power over
205,384 shares and sole power to vote or to direct the voting
of 205,384 shares of Common Stock owned by the
institutional accounts or funds advised by PGALLC as
reported above.

	Pyramis Global Advisors Trust Company ("PGATC"),
900 Salem Street, Smithfield, Rhode Island, 02917, an indirect
wholly-owned subsidiary of FMR LLC and a bank as defined
in Section 3(a)(6) of the Securities Exchange Act of 1934, is
the beneficial owner of 331,948 shares or 0.291% of the
outstanding Common Stock of the Radioshack Corporation as
a result of its serving as investment manager of institutional
accounts owning such shares. The number of shares of
Common Stock of Radioshack Corporation owned by the
institutional account(s) at December 31, 2010 included
107,640 shares of Common Stock resulting from the assumed
conversion of $2,610,000 principal amount of RADIOSHACK
CONV2.5 8/1/13 144A (41.2414 shares of Common Stock for
each $1,000 principal amount of debenture).

	Edward C. Johnson 3d and FMR LLC, through its
control of Pyramis Global Advisors Trust Company, each has
sole dispositive power over 331,948 shares and sole power to
vote or to direct the voting of 310,090 shares of Common
Stock owned by the institutional accounts managed by
PGATC as reported above.

	FIL Limited ("FIL"), Pembroke Hall, 42 Crow Lane,
Hamilton, Bermuda, and various foreign-based subsidiaries
provide investment advisory and management services to a
number of non-U.S. investment companies and certain
institutional investors.  FIL, which is a qualified institution
under section 240.13d-1(b)(1)(ii), is the beneficial owner of
78,000 shares or 0.068% of the Common Stock outstanding of
the Company.

	Partnerships controlled predominantly by members of
the family of Edward C. Johnson 3d, Chairman of FMR LLC
and FIL, or trusts for their benefit, own shares of FIL voting
stock with the right to cast approximately 39% of the total
votes which may be cast by all holders of FIL voting stock.
FMR LLC and FIL are separate and independent corporate
entities, and their Boards of Directors are generally composed
of different individuals.

	FMR LLC and FIL are of the view that they are not
acting as a "group" for purposes of Section 13(d) under the
Securities Exchange Act of 1934 (the "1934" Act) and that
they are not otherwise required to attribute to each other the
"beneficial ownership" of securities "beneficially owned" by
the other corporation within the meaning of Rule 13d-3
promulgated under the 1934 Act.  Therefore, they are of the
view that the shares held by the other corporation need not be
aggregated for purposes of Section 13(d). However, FMR
LLC is making this filing on a voluntary basis as if all of the
shares are beneficially owned by FMR LLC and FIL on a joint
basis.
