Akershus County Municipality (Norwegian: Akershus fylkeskommune) was the regional governing administration of the old Akershus county in Norway. The county municipality was established in its most recent form on 1 January 1976 when the law was changed to allow elected county councils in Norway. The county municipality was dissolved on 1 January 2020, when Akershus was merged with the neighboring counties of Buskerud and Østfold, creating the new Viken county which is led by the Viken County Municipality. The administrative seat is located in Oslo (which was not part of Akershus) and the county mayor was Anette Solli. On 1 January 2024, Akershus was re-established as an independent county with expanded borders due to municipal amalgamations in 2020, which will not be reversed.
The Oppland county council (Norwegian: Fylkestinget) was made up of 43 representatives that were elected every four years. The council essentially acted as a Parliament or legislative body for the county and it met several times each year. The council was divided into standing committees and an executive board (fylkesutvalg) which met considerably more often. Both the council and executive board were led by the county mayor (fylkesordfører) who held the executive powers of the county.
