The Langer See is a lake situated in the south-eastern outskirts of Berlin, the capital city of Germany. The lake is aligned south-east to north-west and forms part of the course of the River Dahme. The Langer See is approximately 11 kilometres long, with an average width of 221 metres and an area of 2.43 square kilometres.
The Dahme flows into the Langer See from the Zeuthener See, at the south-east end of the lake by the Berlin suburb of Schmöckwitz. It flows out to the north-west near Köpenick and its confluence with the River Spree. At Schmöckwitz the Langer See also mingles with the Seddinsee.
