USS Prairie (AD–15) was a Dixie-class destroyer tender built just before the start of World War II for the U.S. Navy. Her task was to service destroyers in, or near, battle areas and to keep them fit for duty. Prior to U.S. entry into World War II, Prairie cruised between Atlantic ports from Colon, C.Z. to Argentia, Newfoundland. She was docked at Argentia, tending Allied ships, on 7 December 1941 as the first direct blows of World War II struck the United States.
