German submarine U-343 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II. The submarine was laid down on 1 April 1942 at the Nordseewerke yard at Emden, launched on 21 December 1942 and commissioned on 18 February 1943 under the command of Leutnant zur See Wolfgang Rahn.^[2]

After training with the 8th U-boat Flotilla at Danzig, U-343 was transferred to the 3rd U-boat Flotilla, based at La Pallice in France, for front-line service on 1 November 1943, and then to the 29th U-boat Flotilla, based at Toulon on the Mediterranean coast, on 1 February 1944. On 10 March 1944, U-343 was sunk off Bizerte by depth charges from a British warship. All 51 of her crew members were lost with the U-boat.^[2]
