German submarine U-575 was a Type VIIC U-boat in service of Nazi Germany's Kriegsmarine during World War II. She carried out ten patrols, sailing for 463 days and sinking eight ships totalling 36,010 gross register tons (GRT) and damaged three others of 29,777 GRT. She was a member of 18 separate wolfpacks and was sunk north of the Azores by Allied ships and aircraft on March 1944.

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-575 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.
