USS Caddo Parish, originally named LST-515, was an LST-491-class tank landing ship built for the United States Navy during World War II.

LST-515 was laid down on 3 September 1943, at Seneca, Illinois, by the Chicago Bridge & Iron Company; launched on 31 December 1943; sponsored by Miss Rebekah Brown; and commissioned on 28 January 1944.

[2] She was one of the eight LST's that took part in the disastrous "Exercise Tiger", a practice for the planned invasion of France, in April 1944.

Under attack from German E-boats, LST-515 returned fire and lowered her boats to pick up survivors from LST-507.
