German submarine U-275 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II. The submarine was laid down on 18 January 1942 at the Bremer-Vulkan-Vegesacker Werft (yard) in Bremen as yard number 40. She was launched on 8 October 1942 and commissioned on 25 November under the command of Oberleutnant zur See Helmut Bork.

In nine patrols, she sank two ships of 6,024 gross register tons (GRT). She was a member of four wolfpacks.

She was sunk by a mine in the English Channel in March 1945.

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-275 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).
