German submarine U-158 was a Type IXC U-boat of Nazi Germany's Kriegsmarine built for service during World War II.

Her keel was laid down on 1 November 1940 by DeSchiMAG AG Weser in Bremen as yard number 1000. She was commissioned on 25 September 1941, with Kapitänleutnant Erwin Rostin (Knights Cross) in command.

German Type IXC submarines were slightly larger than the original Type IXBs. U-158 had a displacement of 1,120 tonnes (1,100 long tons) when at the surface and 1,232 tonnes (1,213 long tons) while submerged. The U-boat had a total length of 76.76 m (251 ft 10 in), 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).
