German submarine U-178 was a Type IXD2 U-boat of Nazi Germany's Kriegsmarine built for service during World War II.

Ordered on 28 May 1940, the U-boat was laid down on 24 December 1940 at the AG Weser yard in Bremen as yard number 1018. She was launched on 25 October 1941 and commissioned on 14 February 1942, under the command of Fregattenkapitän Hans Ibekken.

German Type IXD2 submarines were considerably larger than the original Type IXs. U-178 had a displacement of 1,610 tonnes (1,580 long tons) when at the surface and 1,799 tonnes (1,771 long tons) while submerged. The U-boat had a total length of 87.58 m (287 ft 4 in), a pressure hull length of 68.50 m (224 ft 9 in), a beam of 7.50 m (24 ft 7 in), a height of 10.20 m (33 ft 6 in), and a draught of 5.35 m (17 ft 7 in). The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines plus two MWM RS34.5S six-cylinder four-stroke diesel engines for cruising, producing a total of 9,000 metric horsepower (6,620 kW; 8,880 shp) for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of 1,000 shaft horsepower (1,010 PS; 750 kW) for use while submerged. She had two shafts and two 1.85 m (6 ft) propellers. The boat was capable of operating at depths of up to 200 metres (660 ft).
