German submarine U-522 was a Type IXC U-boat of Nazi Germany's Kriegsmarine during World War II.

She was laid down at the Deutsche Werft (yard) in Hamburg as yard number 337 on 9 July 1941, launched on 1 April 1942 and commissioned on 11 June with Kapitänleutnant Herbert Schneider in command.

U-522 began her service career with training as part of the 4th U-boat Flotilla from 11 June 1942. She was reassigned to the 2nd flotilla for operations on 1 October 1942.

She carried out two patrols and sank seven ships. She damaged two more. She was sunk in February 1943 in mid-Atlantic west of Madeira by a British warship.

German Type IXC submarines were slightly larger than the original Type IXBs. U-522 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).
