Operation Wikinger (English: Operation Viking) was a German naval sortie into the North Sea by six destroyers of the Kriegsmarine on 22 February 1940 during the Second World War. Poor inter-service communication and co-operation between the Kriegsmarine and the Luftwaffe resulted in the loss of two German warships through friendly fire bombing and German or British mines. Only sixty survivors were rescued and the operation was called off.

Fliegerkorps X had sent several signals to the naval Marinegruppe West with information about air operations over the North Sea but had not been informed about the naval operation. A request by Marinegruppe West for air support on 23 February led Fliegerkorps X to ask if destroyers were at sea but the reply came too late; a Kampfgeschwader 26 bomber attacked the destroyers.

An inquiry exonerated the bomber crew because they had received no warning and no recognition flares had been fired from the ships. Reports of submarines, indiscriminate firing and general excitement on the destroyers caused uncertainty but the committee ruled that the destroyer Leberecht Maass was bombed and that around 7:56 p.m. there was a big explosion amidships. At 8:04 p.m. there was a bigger explosion on the destroyer Max Schultz, which broke up and sank.
