German submarine U-265

German submarine U-265 was a Type VIIC U-boat of the Nazi German Kriegsmarine during World War II. The submarine was laid down on 3 July 1941 at the Bremer Vulkan yard at Bremen-Vegesack as 'werk' 30, launched on 23 April 1942 and commissioned on 6 June under the command of Oberleutnant Leonhard Aufhammer. After training with the 8th U-boat Flotilla, U-265 was transferred to the 7th U-boat Flotilla, for front-line service from 1 February 1943.

U-265 sank no ships in her short career. Her only patrol began when she departed Kiel on 21 January 1943. Her route took her through the 'gap' between Iceland and the Faroe into the Atlantic Ocean. She was attacked and sunk by a British Flying Fortress of No. 220 Squadron RAF on 3 February.

Forty-six men died; there were no survivors.
