Røyken is a district and village (bygd) and a former municipality in Buskerud, Norway. In 2020 Røyken was merged with the municipalities of Hurum and Asker to form the new Asker Municipality (informally called "Greater Asker") located in the newly formed Viken county. Because Viken seized to exist, all of the new Asker Municipality became part of Akershus County. The administrative centre of the municipality is the village of Midtbygda. The parish of Røken was established as a municipality on 1 January 1838 (see formannskapsdistrikt).

Oslo ATCC, the Area Control Center for the controlled airspace above Østlandet is located here.
