German submarine U-176 was a Type IXC U-boat in Nazi Germany's Kriegsmarine during World War II.

Built at the DeSchiMAG AG Weser shipyard in Bremen, she was laid down on 6 February 1941, launched on 12 September and commissioned on 15 December, under the command of Kapitänleutnant Reiner Dierksen.

U-176 served with the 4. Unterseebootsflotille (U-boat flotilla) while training, and from 1 August 1942 with the 10th U-boat Flotilla, a long-range operations unit. U-176 completed three patrols, sinking 11 ships totalling 53,307 gross register tons (GRT) before she was sunk off Cayo Blanquizal by the Cuban Navy on 15 May 1943.

German Type IXC submarines were slightly larger than the original Type IXBs. U-176 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 shaft horsepower (1,010 PS; 750 kW) 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).
