Buskerud (Urban East Norwegian pronunciation: [ˈbʉ̂skərʉː] ⓘ) is a county in eastern Norway. The 14,694.11-square-kilometre (5,673.43 sq mi) county borders Akershus, Oslo, Innlandet, Vestland, Telemark, and Vestfold counties. It extends from the Drammensfjorden in the southeast to the Hardangervidda mountain range in the northwest. The administrative centre of the county is the city of Drammen.
Buskerud was one of the three counties merged into Viken county on 1 January 2020. On 23 February 2022, the Viken County Council voted 49–38 to submit an application to the Norwegian government to undo the 2020 merger. The Norwegian government agreed and on 1 January 2024, Buskerud county was re-established. The only difference was that the areas of the old Røyken Municipality and the old Hurum Municipality were not part of the re-established Buskerud because those areas had been merged with Asker Municipality and that area was part of Akershus county).

Buskerud county was separated from Akershus county as an amt of its own in 1685, but the amt was smaller than today. It then consisted of the present-day districts of Eiker, Hallingdal, and Ringerike. The areas of Flesberg, Hurum, Kongsberg, Lier, Nore og Uvdal, Rollag, and Røyken were transferred from Akershus amt to Buskerud amt in 1760. The name Buskeruds amt was changed to Buskerud fylke in 1919. In 1964, the area of the old Skoger Municipality was transferred from Vestfold county to Buskerud county. On 1 January 2020, the areas of Røyken Municipality and Hurum Municipality became part of Asker Municipality. Also on 1 January 2020, Buskerud was one of the three counties merged into Viken county. On 23 February 2022, the Viken County Council voted 49–38 to submit an application to the Norwegian government to undo the 2020 merger. The Norwegian government agreed and on 1 January 2024, Buskerud county was re-established. The only difference was that the areas of the old Røyken Municipality and the old Hurum Municipality were not part of the re-established Buskerud because those areas had been merged with Asker Municipality and that area was part of Akershus county).
The area Ringerike may once have been a small kingdom. During the 10th century, Norway's kings Olaf Tryggvason and Olaf Haraldsson grew up at Bønsnes in Ringerike. In the valley of Numedal, silver was mined in Kongsberg from the 17th century until discontinued in 1957. Weapons industry had been developed in Kongsberg from 1814, and various high tech industry companies now represent the town's major employers. In Modum Municipality there was also Blaafarveværket, a cobalt pigment production works (Blue Colour Works).
The county was named after the old Buskerud Manor (Old Norse: Biskupsruð) (Biskopsrøysa) located on the west side of the Drammen River in Åmot in Modum Municipality. The first element is the genitive case of biskup which means "bishop" (referring to the Bishop of Hamar). The last element is ruð which means a "clearing for a farm". The farm was one of the largest in Buskerud, and the original name of the farm (before it became a benefice) was probably Modum. At the time of the Reformation (c. 1536–39) the farm became property of the Crown at which time the farm then served as the residence of the king's bailiffs until 1668.
Buskerud's coat of arms were adopted in April 1966. It features a blue bear whose colours are symbolic of the blue colour works. The silver background of Buskerud's coat of arms represents the silver industry in Kongsberg.
Agriculture, lumber, wood-pulp mills, and other related industries are the county's main economic activities. There is also ample hydroelectric power is produced by the rivers Begna and Randselva. Buskerud has also a large forested area. Substantial income is derived from high tech industries located in Kongsberg. Other significant income comes from the cabin areas in northern Buskerud. The company, Eneas Energy is based here.

Buskerud county extends from the lake Tyrifjorden and the Drammensfjorden in the east to the Hallingskarvet mountains and the Hardangervidda plateau in the west. The county is conventionally divided into several traditional districts. These are Hallingdal, Numedal, Ringerike, and Lower Buskerud, which was originally part of Vestfold.
Today, the district of Hallingdal consists of Flå Municipality, Nesbyen Municipality, Gol Municipality, Hemsedal Municipality, Ål Municipality, and Hol Municipality. The district of Numedal consists of Flesberg Municipality, Rollag Municipality and Nore og Uvdal Municipality. The district of Ringerike consists of Hole Municipality, Krødsherad Municipality, Modum Municipality, Ringerike Municipality, and Sigdal Municipality. The district of Lower Buskerud consists of Drammen Municipality, Kongsberg Municipality, Lier Municipality, and Øvre Eiker Municipality.
Buskerud county's western parts are a mountainous plateau with forested valleys and high, grassy pastures; its eastern parts contains a lowland basin with many lakes and streams. Tyrifjorden and Krøderen are the largest lakes. Numedalslågen, the third longest river in Norway, starting in Vestland county, runs through Buskerud into Vestfold where it reaches the sea, while the river Begna sweeps into the lake Sperillen.
