German submarine U-1000 was a Type VIIC/41 U-boat built during World War II for service in the Battle of the Atlantic. She was completed in Hamburg in November 1943, and after working up trials was moved to Egersund in Norway in June 1944. From there she conducted her only war patrol in the waters off Norway, in the North Sea and towards the Arctic Circle, but found no enemy ships to target, returning to Bergen without firing a shot. She did however manage to recover two Norwegian airmen of the British Royal Air Force, whose Mosquito aircraft had been shot down by two days before they were rescued from the sea.
