German submarine U-296 was a Type VIIC/41 U-boat of Nazi Germany's Kriegsmarine during World War II. She was laid down on 23 January 1943 by the Bremer Vulkan Werft (yard) at Bremen-Vegesack as yard number 61, launched on 5 September 1943 and commissioned on 3 November with Oberleutnant zur See Karl-Heinz Rasch in command. In three patrols, she did not sink or damage any ships. She was regarded as missing with all hands (42 men), in the approaches to the North Channel, (between Northern Ireland and mainland Great Britain), in March 1945.
