USS Trumpetfish (SS-425), a Balao-class submarine, was the only ship of the United States Navy to be named for trumpetfish, any of several fishes so-called for their deep, compressed body and long, tubular snout. Her keel was laid down on 23 August 1943 at Philadelphia by the Cramp Shipbuilding Company. She was launched on 13 May 1945 sponsored by Mrs. Oswald S. Colclough, and commissioned on 29 January 1946.

Trumpetfish and Tusk are erroneously listed with the Tench class in some sources, as their hull numbers are in the sequence assigned to that class.
