German submarine 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 April 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 (10 January 1942 until 14 May 1943) and Kapitänleutnant Friedrich Guggenberger (15 May until 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. Martin PBM Mariner amphibious aircraft in the South Atlantic Ocean on 19 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.
