German submarine U-376 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.

The submarine was laid down in April 1940 in Kiel, launched in July 1941, and commissioned in August 1941 under the command of Oberleutnant zur See Friedrich-Karl Marks.

U-376 was attached to the 6th U-boat Flotilla, and was ready for front-line service from 1 March 1942. Operating from Norwegian bases, from July 1942 she served with the 11th U-boat Flotilla, and was transferred to the 3rd U-boat Flotilla, based in France, in early 1943.

U-376 sailed on eight combat patrols, sinking only two merchant ships totalling 10,146 tons before she went missing in the Bay of Biscay in April 1943.

U-376 was ordered by the Kriegsmarine on 16 October 1939. She was laid down about six months later at the Howaldtswerke yard in Kiel, on 3 April 1940. Just over a year and three months later, U-376 was launched in Kiel on 10 July 1941. She was formally commissioned into the Kriegsmarine later that year on 21 August.

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-376 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged. She had a total length of 67.10 m (220 ft 2 in), a pressure hull length of 50.50 m (165 ft 8 in), a beam of 6.20 m (20 ft 4 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.74 m (15 ft 7 in). The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,060 to 2,350 kW; 2,760 to 3,160 shp) for use while surfaced, two AEG GU 460/8–27 double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use while submerged. She had two shafts and two 1.23 m (4 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).
