USS Sphinx (ARL-24) was a landing craft repair ship of the United States Navy, originally commissioned in 1945 near the end of World War II. Built as LST-963 and later converted to an Achelous-class repair ship, she provided crucial repair and maintenance services to amphibious forces in the Pacific. Reactivated for the Vietnam War, USS Sphinx supported riverine and coastal operations, earning multiple campaign stars for her service. Decommissioned in 1971, she continued to serve in civilian roles before being struck from the Naval Vessel Register.
