German Submarine U-333

German submarine U-333 was a Type VIIC U-boat of the Nazi German Kriegsmarine during World War II. The submarine was laid down on 11 March 1940 at the Nordseewerke yard at Emden, launched on 14 June 1941, and commissioned on 25 August 1941 under the command of Kapitänleutnant Peter-Erich Cremer. After training with the 5th U-boat flotilla at Kiel, on 1 January 1942 U-333 was transferred to the 3rd U-boat Flotilla based at La Pallice for front-line service.

The U-boat made 12 combat patrols in the next three years, and sank seven merchant ships totalling 32,107 gross register tons (GRT), damaged another of 8,327 GRT, and also engaged and damaged the 925 GRT Flower class corvette HMS Crocus. U-333 was sunk in the English Channel with depth charges from two British warships on 31 July 1944.

U-333 bore the "three little fishes" emblem on its conning tower.
