The French submarine Dauphin was a Reqin (French for shark)-class submarine built for the French Navy in the mid-1920s. Laid down in December 1922, it was launched in April 1925 and commissioned in November 1927. It was captured by Italian forces on 8 December 1942 and renamed FR 115. It was later recaptured by the Germans on 9 September 1943, then scuttled on 15 September 1943. The name Dauphin comes from the French word for Dolphin.
