USS Bumper (SS-333), a Balao-class submarine, was a ship of the United States Navy named for the bumper, a small fish of the North and South Atlantic Ocean.

Between 22 April and 15 August 1945 Bumper completed two war patrols in the Java Sea, South China Sea, and Gulf of Siam. During this time she sank a 1,189-gross register ton tanker at sea, sank another small tanker at anchor, and sank four miscellaneous small craft by gunfire.

She served in the Turkish Navy as TCG Çanakkale (S 333) from 1950 to 1976.
