German submarine U-182 was a Type IX D 2 U-boat of the Nazi German Kriegsmarine which served in World War II. Her keel was laid down on 7 April 1941 at AG Weser, Bremen as 'werk' 1022; she was launched on 3 March 1942 and commissioned on 30 June of the same year. She carried out a single war patrol, sinking five merchant vessels and spending 159 days at sea. U-182 was probably sunk near Madeira on 16 May 1943 by USS MacKenzie. 61 crew members and three prisoners of war died. The boat had been unsuccessfully attacked by a USAAF B-24 Liberator the previous day.
