German submarine U-593 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II. She was laid down on 17 December 1940 by Blohm & Voss in Hamburg as yard number 569, launched on 3 September 1941 and commissioned on 23 October under Kapitänleutnant Gerd Kelbling.

The boat's service began on 23 October 1941 with training as part of the 8th U-boat Flotilla. She was transferred to the 7th flotilla on 1 March 1942 and moved on to the 29th flotilla on 1 November.
