The Barents Sea campaign in 1941 was a submarine operation in the Arctic waters of the Barents Sea during the Second World War. The operation was conducted by Soviet and British submarines. The submarines were based at Polyarny in the Soviet Union, to attack German shipping along the Norwegian coast.

The Soviet submarines suffered no losses but achieved only modest results, because of the Arctic climate and inexperience. The British submarines, with experienced crews, had more success. The Kriegsmarine was forced to suspend coastal traffic and send supplies through the Baltic Sea and overland through Finland, substantially hampering German land operations in the far north.
