Innlandet is a county in Norway. It was created on 1 January 2020 with the merger of the old counties of Oppland and Hedmark (Jevnaker Municipality and Lunner Municipality were transferred to the neighboring county of Viken on the same date). The new county has an area of 52,113 square kilometres (20,121 sq mi), making it the largest county in Norway after the division of the old Troms og Finnmark county in 2024.
The region was known as Opplandene or Opplanda since the middle ages. Historically part of Akershus, Oplandene County existed from 1757 to 1781, when it was divided into Christians County and Hedemarken County, also known as Western and Eastern Oplandene. In 1919 the two counties were renamed Oppland and Hedmark, and in 2020 they were again merged under the name Innlandet (with the exception of Jevnaker Municipality and Lunner Municipality, which went to the new county of Viken). This present name is a newly constructed name with no historical basis as a subdivision name and was recommended not to be used by the Norwegian Language Council. It translates to "The Inland". The county covers approximately 17% of the total area of the mainland area of Norway. It stretches from Akershus, Buskerud, and the Oslo region in the south to Trøndelag county in the north. In the northwest, the county borders Møre og Romsdal and the Vestland county in the west. To the east the county borders the Swedish counties of Jämtland, Värmland and Dalarna.
