U-513 was a type IXC U-boat built for service in Nazi Germany's Kriegsmarine during World War II.

She was laid down on 26 May 1941 by the naval construction firm Deutsche Werft AG in Hamburg as yard number 309, and commissioned on 10 January 1942. Her commanders were Korvettenkapitän Rolf Rüggeberg (January 1942 to April 1943) and Kapitänleutnant Friedrich Guggenberger (15 May to 19 July 1943). Her training period was from 10 January 1942 to 31 August, as part of the 4th U-boat Flotilla. She was then assigned to the 10th U-boat Flotilla for operations.

She sank six ships with a total tonnage of 29,940 gross register tons (GRT) and damaged two more with a total tonnage of 13,177 GRT. The boat was a member of two wolfpacks. She was sunk by depth charges from a U.S. PBY Catalina-type amphibious aircraft in the South Atlantic Ocean in July 1943.

In 2011 after nine years research and two years of seagoing searches, the expedition led by the explorers of Schurmann Family located U-513, 85 km (46 nmi) east of their hometown of Florianópolis. The find was announced worldwide on 17 June 2011, when the Schürmanns produced images of a Side-scanning sonar. A dive was made in 2012, where photos and video images were recorded.

German Type IXC submarines were slightly larger than the original Type IXBs. U-513 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).
