USS Bellerophon (ARL-31) was one of 39 Achelous-class landing craft repair ships built for the United States Navy during World War II.

Named for Bellerophon (a hero of Greek mythology, the son of Eurymede by either the Corinthian King, Glaucus, or the sea god, Poseidon), she was the only U.S.

Originally planned as an LST, she was redesignated as landing craft repair ship ARL-31 prior to construction.

When a strike by civilian workers paralyzed civilian yards during the latter part of October, Bellerophon began making voyage repairs to Operation Magic Carpet ships while also carrying out some conversion work to enable attack cargo ships to serve as passenger carriers.

Her name was struck from the Naval Vessel Register in October, 1977 and she was sold on 20 June 1980 to the Levin Metals Corporation of Richmond, California for scrapping.
