German submarine U-105 was a Type IXB U-boat of Nazi Germany's Kriegsmarine. She was ordered in May 1938 as part of Germany's naval rearmament program. Her keel was laid down in Bremen in November 1938. After roughly seven months of construction, she was launched in June 1940 and formally commissioned into the Kriegsmarine in September 1940.

During her three-year career, U-105 sank 23 vessels for a total loss of 125,470 gross register tons (GRT) before being sunk by the Free French Forces off the coast of Dakar (Senegal) in June 1943.

U-105 was ordered by Nazi Germany's Kriegsmarine on 24 May 1938; her keel was laid down on 16 November 1938 by DeSchiMAG AG Weser in Bremen as yard number 968. She was launched on 15 June 1940 and commissioned on 10 September under the command of Kapitänleutnant Georg Schewe.

German Type IXB submarines were slightly larger than the original German Type IX submarines, later designated IXA. U-105 had a displacement of 1,051 tonnes (1,034 long tons) when at the surface and 1,178 tonnes (1,159 long tons) while submerged. The U-boat had a total length of 76.50 m (251 ft), a pressure hull length of 58.75 m (192 ft 9 in), a beam of 6.76 m (22 ft 2 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.70 m (15 ft 5 in). The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of 4,400 metric horsepower (3,240 kW; 4,340 shp) for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of 1,000 metric horsepower (740 kW; 990 shp) for use while submerged. She had two shafts and two 1.92 m (6 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).
