German submarine U-239 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II. The submarine was laid down on 14 May 1942 at the Friedrich Krupp Germaniawerft yard at Kiel as yard number 669, launched on 28 January 1943 and commissioned on 13 March under the command of Leutnant zur See Ulrich Vöge. After training with the 5th U-boat Flotilla at Kiel, she went to the 22nd flotilla as a 'school' boat and then back to the fifth flotilla. She was damaged in Kiel by British bombs on 24 July 1944 and broken up in the same year.
