German submarine U-751 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II. Built as yard number 134 of the Kriegsmarinewerft shipyard in Wilhelmshaven, she was commissioned on 31 January 1941. She served with 7th U-boat Flotilla until 1 June as a training boat, and as an operational boat until 17 July 1942, under the command of Kapitänleutnant Gerhard Bigalk. U-751 served in seven patrols with the 7th U-boat Flotilla, sinking the escort carrier HMS Audacity. The U-boat was attacked with depth charges from aircraft on 17 July 1942 and sank with the loss of all 48 crew members.
