Drevviken is a lake in southern Stockholm, Sweden, shared by the four municipalities Stockholm, Haninge, Huddinge, and Tyresö.
While much of the surrounding area is used for one-family houses, the lake and the green space north of it are considered to be of great recreational and natural importance and forms part of a suggested nature reserve around lake Flaten.
