Buskerud (Urban East Norwegian pronunciation: [ˈbʉ̂skərʉː] ) is a county and a current electoral district in Norway, bordering Akershus, Oslo, Innlandet, Vestland, Telemark and Vestfold. It extends from Oslofjord and Drammensfjord in the southeast to the Hardangervidda mountain range in the northwest. The administrative centre of the county is Drammen.
Buskerud was one of the three counties merged into Viken on 1 January 2020. On 23 February 2022, the Viken County Council voted 49-38 to submit an application to the Norwegian government for a demerger of itself. Due to this, Buskerud (except the area forming the defunct municipalities of Røyken and Hurum) was re-established in 2024.
