USS Pomfret (SS-391), a Balao-class submarine, was a ship of the United States Navy named for the pomfret, a fish of the seabream family; a powerful and speedy swimmer, capable of operating at great depths.

Pomfret was laid down 14 July 1943 and launched 27 October 1943 by the Portsmouth Navy Yard, in Kittery, Maine, sponsored by Miss Marilyn Maloney, daughter of Senator Francis Maloney; and commissioned 19 February 1944, Commander Frank C. Acker in command.

After training, the new submarine arrived Pearl Harbor 1 June 1944. She departed Pearl Harbor 23 June and proceeded via Midway to her first patrol area—the east coast of Kyūshū and Bungo Suido. On 6 July she made an emergency dive when attacked by a Japanese plane. On 12 July she allowed a Japanese hospital ship to proceed in peace. After attempting an attack on a battleship, she arrived at Midway 16 August.

On 10 September she departed Midway for the Luzon Straits-South China Sea area to conduct her second patrol. She sighted two enemy battleships on 26 September, but their speed and the presence of an enemy submarine prevented an attack.

On 2 October Pomfret sank Tsuyama Maru, a 6,962-ton passenger-cargo vessel. After the usual depth charging, she departed for Saipan and moored in Tanapag Harbor 12 October.
