German submarine U-180 was a Type IXD1 transport U-boat of the Nazi German Kriegsmarine which served in World War II. Her keel was laid down on 25 February 1941 at the AG Weser yard in Bremen as 'werk' 1020. She was launched on 10 December 1941 and commissioned on 16 May 1942 under Fregattenkapitän Werner Musenberg. Stripped of torpedo armament, the Type IXD1s were designated as transport submarines, and could carry up to 252 tonnes of freight. U-180 was used primarily in clandestine operations.
