German submarine U-175 was a Type IXC U-boat of Nazi Germany's Kriegsmarine built for service during World War II. She was laid down on 30 January 1941 at Bremen, and commissioned on 5 December 1941 with Kapitänleutnant Heinrich Bruns in command. After training with the 4th U-boat Flotilla, U-175 was transferred to the 10th U-boat Flotilla for front-line service. Throughout her career, the boat undertook three war patrols during which she sank ten merchant ships amounting to a total of 40,619 gross register tons (GRT) before being sunk by the US Coast Guard cutter Spencer on 17 April 1943.

U-175 was ordered by the Kriegsmarine on 23 December 1939. She was constructed as part of Plan Z, a naval construction program that envisaged the acquisition of 249 U-boats along with numerous surface vessels by 1948, and which was in direct contravention of Germany's obligations under the Anglo-German Naval Agreement. The vessel's keel was laid down in the DeSchiMAG AG Weser shipyard in Bremen on 30 January 1941 at which point it became known by the yard number or designation 1015. Built alongside U-174 and U-176, the boat's crew was slowly assembled during construction, they were billeted within a building at the North German Lloyd Shipping Company, also in Bremen. After about nine months of construction U-175 was launched on 2 September 1941.
