The PGM-1-class motor gunboats were a class of eight gunboats converted for the United States Navy from 1943-1944 and were succeeded by the PGM-9-class motor gunboats. All eight PGM-1s were converted from SC-497-class submarine chasers. The PGM-1s were created to support PT boats in the Pacific, but were too slow to keep up. The PGM-1s were discontinued and the PGM-9s, also too slow, were shifted to support minesweeping ships instead.

PGM-7 was the only PGM-1-class vessel lost in World War II. The others were sent to the Foreign Liquidation Commission in 1947. Their exact fate is unknown.
