German submarine U-1163 was a Type VIIC/41 U-boat of Nazi Germany's Kriegsmarine during World War II.

She was launched on 12 June 1943 and commissioned under the command of Oberleutnant zur See Ernst-Ludwig Balduhn on 6 October of that year.

The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,060 to 2,350 kW; 2,760 to 3,160 shp) for use while surfaced, two Siemens-Schuckert GU 343/38-8 double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use while submerged.

Despite her lack of ships sunk, U-1163 was one of only a handful of German U-boats in World War II to help shoot down a De Havilland Mosquito on 2 August 1944.

For 17 days, U-1163 roamed the Arctic Ocean in search of any Allied convoys heading to the Soviet Union.

For 22 days, she traveled through the Arctic Ocean in search of any Allied vessels heading to or from the Soviet Union.

Revoljucija, a Soviet 433 GRT cargo steam ship, had been separated from her convoy after developing engine trouble, and was stopped, protected by a single minesweeper.
