German submarine U-525 was a Type IXC/40 U-boat of Nazi Germany's Kriegsmarine built for service during World War II.

Her keel was laid down on 10 September 1941 by the Deutsche Werft in Hamburg as yard number 340. She was launched on 20 May 1942 and commissioned on 30 July with Kapitänleutnant Hans-Joachim Drewitz in command.

The U-boat's service began with training as part of the 4th U-boat Flotilla on 30 July 1942. She then moved to the 10th flotilla on 1 January 1943 for operations.

She was a member of six wolfpacks.

She carried out three patrols and sank one ship of 3,454 GRT.

She was sunk by US aircraft, northwest of the Azores, in August 1943

German Type IXC/40 submarines were slightly larger than the original Type IXCs. U-525 had a displacement of 1,144 tonnes (1,126 long tons) when at the surface and 1,257 tonnes (1,237 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 6.86 m (22 ft 6 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.67 m (15 ft 4 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).
