German submarine U-652 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II. The submarine was laid down on 5 February 1940 at the Howaldtswerke yard at Hamburg, launched on 7 February 1941, and commissioned on 3 April 1941 under the command of Oberleutnant zur See Georg-Werner Fraatz.

Attached to 3rd U-boat Flotilla based at Kiel, U-652 completed her training period on 30 June 1941 and was assigned to front-line service. In September 1941 she was involved in the "Greer Incident", attacking and being counter-attacked by the supposedly neutral American destroyer Greer (DD-145), an incident that brought the United States closer to war with Germany. As a direct result of the Greer incident the US President Franklin D. Roosevelt gave a speech on 11 September 1941 in which he confirmed that all US ships had been ordered to shoot on sight at all Axis ships and submarines in the Battle of the Atlantic. U-652 was transferred to 29th U-boat Flotilla based at La Spezia, Italy on 1 January 1942. She was scuttled on 2 June 1942.
