German submarine U-429 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine originally built for the Italian Regia Marina during World War II. Her keel was laid down on 14 September 1942 by Danziger Werft of Danzig. She was then commissioned as S-4 on 14 July 1943 under the command of Tenente di vascello Angelo Amendolia.

Following the Italian armistice on 8 September 1943, the Kriegsmarine took possession of the U-429, which was still in German waters, along with the Template:GS and Template:GS. These boats were not deemed advanced or useful enough for full war service, and on 27 October 1943 they were turned over to training flotillas for service in the Baltic Sea, training up submarine crews for dispatch to operating boats, mainly based in France. After a very uneventful service life, the U-429 was caught in an open dock during a U.S. Eighth Air Force raid on the city of Wilhelmshaven on 30 March 1945, and destroyed by bombing, although her crew were not on board at the time of the attack.
