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.
Service history 
1st patrol 
On 18 April U-180 sank the British 8,132 ton tanker Corbis about 500 miles east southeast of Port Elizabeth, South Africa. Three days later, on 21 April, the boat made her rendezvous with the Japanese submarine I-29, just east of Madagascar in the Indian Ocean, and exchanged the two Indians for two Japanese Navy officers, both shipbuilding officers, Captains Emi Tetsushiro and Tomonaga Hideo, who were to study U-boat building techniques upon their arrival in Germany. Bose and Hasan's transfer is the only known record of a civilian transfer between two submarines of two different navies in World War II. Also received were two tonnes of gold ingots as payment from Japan for weapons technology.
During this voyage, U-180 was supplied by U-462 on the way to the exchange. She was supposed to be refueled by U-463 on the way back, but that boat was sunk by the British on 16 May 1943. On 19 June, U-180 was refueled by U-530.
2nd patrol and loss 
Under the command of Oberleutnant Rolf Riesen, U-180 sailed from Bordeaux on 20 August 1944 bound for Japan. She was reported sunk off the Bay of Biscay on 23 August 1944, with the loss of all of her 56 crew. The official verdict is "sunk by a mine", however, some experts speculate that trouble with the schnorkel (the underwater breathing and engine operating device), may have been the cause.

- U-180 is the submarine carrying Nazi party secretary, Martin Bormann, to South America in the Jack Higgins thriller, Thunder Point.
- U-180 is featured in the thriller Spook's Gold by Andrew Wood. The rendezvous on 21 April between U-180 and the I-29, as well as an exchange of gold and military goods is a key element of the plot.
