Flaten is a lake in southern Stockholm, Sweden, located just north of Lake Drevviken. The name is also used for the surrounding area and the nature reserve created there in 2007.^[3]

Flaten has the best water quality of all lakes around the Swedish capital and is highly popular for bathing and angling. The surrounding area is dominated by forests, with allotment-gardens and some industrial activities located north of the lake. Algal bloom occasionally occurs in spring.^[4]
