USS Walrus (SS-437), a World War II Tench-class submarine, was the third ship of the United States Navy to be named for the walrus, a gregarious, aquatic mammal found in Arctic waters, related to the seal and a prime source of leather, oil, ivory, and food. Like the second USS Walrus (SS-431), she was not completed.

Walrus '​s keel was laid down on 21 June 1945 by the Electric Boat Company at Groton, Connecticut. Work on the submarine was suspended on 7 January 1946 when the contract for her construction was cancelled, although she was launched on 20 September 1946, sponsored by Miss Winifred P. Nagle.

Walrus '​s hull was assigned to the New London Group of the Atlantic Reserve Fleet on 9 December 1952. Her name was stricken from the Naval Vessel Register on 9 June 1958 and she was sold incomplete for scrapping.
