Røyken is a village and municipality in Buskerud county, Norway. 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).
General information 
The municipality (originally the parish) is named after the old Røyken farm (Norse Raukvin), since the first church was built there. The first element is raukr which means "pile, stack; mountain" and the last element is vin which means "meadow" or "pasture".
See also Røykenvik.
The coat-of-arms is from modern times. They were granted on 15 December 1967. The figure shows a yellow fire on a blue background. It was chosen as a semi-canting symbol to represent smoke (which cannot be depicted in heraldry). The background for the motif is a common misunderstanding of the name as røyken the definite form of røyk meaning "smoke".
Røyken is located south of Lier and Asker, on the northern part of the Hurum peninsula north of Hurum municipality. It lies between Oslofjord and Drammensfjord. It is connected to the eastern side of the Oslofjord via Hurum municipality and the Oslofjord Tunnel. The tunnel is 7.2 kilometres (4.5 mi) long and connects Hurumhalvøya to Akershus county.
The district includes large amounts of residential zones with beautiful sights of the sea. The administration is situated in the village of Midtbygda. The main population centers are the villages of Hyggen, Hallenskog, Nærsnes, Røyken, Slemmestad, Spikkestad, and Åros. Many people live in the northern part of Bødalen and its vicinities, which is a continuous residential area that continues throughout Asker and Bærum to Oslo.
