The Finnish Naval Detachment K (Finnish: Laivasto-osasto K) was a flotilla that operated on Lake Ladoga during World War II. The Continuation War began in the summer of 1941. The Finns, who had operated naval units on Lake Ladoga before World War II, began reestablishing a flotilla on the lake as soon as their troops reached its shores early on in the war. The headquarters was formed in Läskelä on 2 August 1941 and by 6 August 150 motor boats, two tugs (used as minelayers) and four steam ferries had been transferred there.
