German submarine U-177 was a Type IXD2 U-boat of Nazi Germany's Kriegsmarine during World War II. The submarine was laid down on 25 November 1940, at the DeSchiMAG AG Weser yard in Bremen, as yard number 1017. She was launched on 1 October 1941, and commissioned on 14 March 1942, under the command of Kapitänleutnant Wilhelm Schulze. After a period of training with the 4th U-boat Flotilla at Stettin, the boat was transferred to the 10th flotilla on 1 October 1942, and based at Lorient, for front-line service, she was then reassigned to the 12th flotilla at Bordeaux on 1 December.

She sank 14 ships of 87,388 gross register tons (GRT) and damaged one other of 2,588 GRT, but was herself sunk on 6 February 1944, in the Atlantic west of Ascension Island by a US Navy aircraft.
