German submarine U-571 was a Type VIIC U-boat built for the Nazi Germany's Kriegsmarine for service during World War II. U-571 conducted eleven war patrols, sinking seven ships totalling 47,169 gross register tons (GRT), and damaging one other, which displaced 11,394 tons. On 28 January 1944 she was attacked by an Australian-crewed Sunderland aircraft from No. 461 Squadron RAAF west of Ireland and was destroyed by depth charges. All hands were lost.

The fictional 2000 U.S. war film U-571 has no relation to this U-boat, but is very loosely based on the British capture of U-110 and her Enigma and cipher keys.

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-571 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 Brown, Boveri & Cie GG UB 720/8 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).
