German submarine U-104 was a Type IXB U-boat of Nazi Germany's Kriegsmarine during World War II. She was ordered by the Kriegsmarine on 24 May 1938 as part of the German naval rearmament program Plan Z. Her keel was laid down by DeSchiMAG AG Weser in Bremen in November 1939. Following about six and a half months of construction, she was launched on 25 May 1940 and formally commissioned into the Kriegsmarine on 19 August 1940.

U-104 had a very short career, sinking just one enemy vessel and damaging one other during one war patrol. In the middle of her first patrol, U-104 was posted missing off the north coast of Ireland on 30 November 1940 and was presumed sunk in minefield SN 44, which was laid a few days prior to her arrival in the area.
