USS S-11 (SS-116) was a second-group (S-3 or "Government") S-class submarine of the United States Navy. Her keel was laid down on 2 December 1919 by the Portsmouth Navy Yard. She was launched on 7 February 1921 sponsored by Miss Anna E. Roosevelt and commissioned on 11 January 1923 with Lieutenant Wilder D. Baker in command.
Supplementing duties along the northeast coast, S-11 visited Guantanamo, Cuba, in 1923, and Saint Thomas, United States Virgin Islands, Trinidad, and Coco Solo in 1924. Sailing from New London, Connecticut, on 29 September, via the Panama Canal and California, she visited Hawaii from 27 April to 25 May 1925, before returning to New London on 12 July. S-11 operated in the Panama Canal area from January through April 1926, visited Kingston, Jamaica, from 20 March to 28 March 1927, and served again in the Panama Canal area from February into April 1928. From 1929 into 1936, S-11 operated almost exclusively in the Panama Canal area, but was in Miami Florida, on 31 March 1930 and visited Washington, DC, from 15 May to 5 June 1933. From at least 30 June 1929 until at least 7 August 1931, Commanding officer was V.R. Murphy. Departing Coco Solo on 13 June 1936, S-11 arrived at Philadelphia, Pennsylvania, on 22 June, and was decommissioned there on 30 September.
S-11 was recommissioned on 6 September 1940 at Philadelphia. After voyages from New London to Philadelphia, Bermuda, and St. Thomas in 1941, S-11 arrived at the Coco Solo submarine base in the Panama Canal Zone, on 5 October that year. S-11 served in the Panama Canal area from then into June 1943, and next at Trinidad into February 1944. Following overhaul in the Panama Canal area, S-11 sailed in July via Aruba to Trinidad, where she operated into October. Arriving at Guantanamo Bay on 26 October, she served there into January 1945. After a voyage to the Panama Canal area, she sailed from there on 8 February, arrived at New London on 24 February, and at Philadelphia on 28 March. S-11 was decommissioned on 2 May of that year at Philadelphia and was struck from the Naval Vessel Register. She was sold on 28 October 1945 to Rosoff Brothers of New York City. Resold to Northern Metals Company of Philadelphia, Pennsylvania, on an unspecified date, she was scrapped.
