USS Radiant (AMc-99) was an Accentor-class coastal minesweeper acquired by the U.S. Navy for the dangerous task of removing mines from minefields laid in the water to prevent ships from passing.

Radiant was laid down by Anderson and Cristofani, San Francisco, California, 26 June 1941; launched 27 September 1941; sponsored by Mrs. V. Moyland; and placed in service 11 February 1942.

She operated off the Pacific Northwest until assigned to the newly-formed Seventeenth Naval District (Alaska and Aleutian islands) on 12 April 1944.

Radiant was struck from the Navy list 12 March 1946, transferred to the Maritime Commission, and sold to North Shore Packing Co., Ltd., 7 February 1947.
