Viken (county) Viken is a county in eastern Norway formed by the regional merger of former Akershus, Buskerud and Østfold that took effect on 1 January 2020. The county borders Oslo and the Skagerrak, and contains a mix of urban and rural municipalities including Drammen, Bærum, Fredrikstad, Sarpsborg, and Asker. Viken's creation provoked debate involving Norwegian Parliament, Prime Minister Erna Solberg, Labour Party, Conservative Party and regional movements such as Østlandssamen and local municipal councils.
The area encompassed by Viken has deep medieval and Viking Age roots connected to the historical region of Viken (historical region), mentioned in sagas involving figures like Harald Fairhair and events such as the Battle of Hafrsfjord. In the early modern era, territories here were shaped by treaties including the Treaty of Roskilde and by unions involving the Kingdom of Denmark–Norway. Industrialization in the 19th century transformed towns such as Fredrikstad and Drammen, tied to enterprises like Norsk Hydro and the timber trade with ports like Christiania (Oslo). The 20th century saw the area occupied during World War II and affected by campaigns involving Operation Weserübung and local resistance groups connected to Milorg. Contemporary administrative changes resulted from the Norwegian regional reform debated in Stortinget and influenced by commissions led by figures associated with Ministry of Local Government and Modernisation (Norway).
Viken spans coastal fjords, river valleys and inland highlands, including the mouths of the Glomma and valleys of the Drammenselva. The county's coastline on the Skagerrak includes archipelagos near Oslofjord, with islands used by municipalities such as Moss. Inland features reach toward the Hedmark and Oppland borderlands with forests containing parts of Romeriksåsene and access to mountain areas near Jotunheimen via transit corridors. The climate ranges from maritime temperate on the coast influenced by the North Atlantic Current to colder continental conditions in upland areas, with snowfall affecting sites like Hemsedal and rainfall patterns shaped by proximity to Kattegat and prevailing westerlies.
Viken is administered through a county council (fylkesting) seated in a regional center; political forces include Labour Party, Conservative Party, Centre Party, Progress Party and regional lists such as Viken-lista. The county's responsibilities interact with national bodies including Ministry of Transport (Norway), Ministry of Education and Research (Norway), and Directorate for Cultural Heritage (Norway), and with municipal governments like those of Bærum and Fredrikstad. Judicial matters fall under courts like Borgarting and emergency coordination is linked to agencies such as Norwegian Police Service, Norwegian Directorate for Civil Protection, and Norwegian Public Roads Administration.
Viken's economy combines industry, services, and agriculture: manufacturing centers in Drammen and Kongsberg (noted for companies like Kongsberg Gruppen), shipping and port activity in Fredrikstad and Moss, technology clusters in Bærum linked to firms such as Telenor, and research institutions including University of Oslo facilities near the border and the Norwegian University of Science and Technology collaborations. Agriculture persists in regions around Rakkestad and Eidsberg, while energy production involves hydropower plants on the Glomma and distribution by companies like Statkraft. Infrastructure projects have involved the European route E6, E18, rail upgrades with Norwegian State Railways and initiatives connected to the Oslo Package transport funding scheme.
The population is diverse, concentrated in urban municipalities such as Bærum, Asker, Drammen, Fredrikstad and Sarpsborg, with immigrant communities from countries including Poland, Pakistan, Somalia and Syria. Cultural life draws on institutions like the Nationaltheatret (nearby), regional museums such as Fredrikstad Museum and Drammen Museum, music festivals including the Øyafestivalen influence from Oslo and local events in Halden linked to Fredriksten Fortress. Sporting organizations include clubs like Vålerenga Fotball influence across the region, ice hockey teams such as Sparta Warriors, and winter sport access at resorts connected to Hemsedal Skisenter.
Viken is served by major road corridors (E6, E18), rail lines operated by Vy (company) and freight services by CargoNet. Coastal ferries call at ports like Moss and commuter ferries operate across Oslofjord to Oslo. Air transport is facilitated by Oslo Airport, Gardermoen (just outside county boundaries) and by regional airfields such as Moss Airport, Rygge (historically) and Sandefjord Airport, Torp linking to low-cost carriers. Public transit networks involve transit authorities like Ruter coordinating buses, trams near Oslo fringes, and local bus operators.
