HMS Truculent was a British submarine of the third group of the T class. She was built as P315 by Vickers Armstrong, Barrow, and launched on 12 September 1942. Truculent was lost following a post-war accident with a Swedish oil tanker in the Thames Estuary in January 1950.

Truculent spent much of her World War II wartime service in the Pacific Far East, except for a period in early 1943, operating in home waters. Here, she sank the German submarine U-308, which was on her first war patrol, with all hands. She also took part in Operation Source, towing the X-class midget submarine X-6 to Norway to attack the heavy Kriegsmarine warships Tirpitz, Scharnhorst and Lützow.

On her transfer to the Pacific, she sank the Japanese army cargo ship Yasushima Maru; the small Japanese vessel Mantai; the Japanese merchant cargo ship, turned hell ship, Harugiku Maru and five Japanese sailing vessels. She also laid mines, one of which damaged the Japanese minelayer Hatsutaka.

She survived the war and returned to the United Kingdom to continue in service with the Royal Navy.
