USS Amphitrite (ARL-29) was one of 39 Achelous-class landing craft repair ships built for the United States Navy during World War II.

Originally laid down as LST-1124 on 6 November 1944 at Seneca, Illinois by the Chicago Bridge & Iron Works; launched on 1 February 1945; sponsored by Miss Lillie Williams Kidd; placed in reduced commission on 13 February 1945 for the voyage to Baltimore, Maryland where she was to be converted from a tank landing ship to a landing craft repair ship; decommissioned in Baltimore on 3 March 1945; converted by Bethlehem Steel's Key Highway Shipyard, and placed in full commission as USS Amphitrite (ARL-29) on 28 June 1945.

Continuing across the Pacific with Task Unit (TU) 13.11.97, she reported to her first duty station, Buckner Bay, Okinawa, in October.

The ship remained in Qingdao (save for a round-trip voyage in July during which she towed USS APL-29 to Sasebo, Japan) until 24 September.

She was placed out of commission at San Diego on 1 January 1947 and was berthed with that portion of the Pacific Reserve Fleet located there.
