Finnskogen ("Forest of the Finns") is an area of Norway and Sweden situated in the counties of Innlandet and Värmland respectively, so named because of immigration of Finnish people in the 17th century, the so-called Skogfinner/"Forest Finns".
The core area of Finnskogen lies in the eastern part of a small region known as Solør, on the border with Sweden. It consists of a forested belt of land, about 32 km (20 mi) wide. It is adjacent to the Swedish region with similar Finnish immigration, named Finnskogarna. There are also similar forested areas in other parts of eastern Norway, Brandval, Vinger Finnskog of Kongsvinger (Austmarka), Søre Osen, Finnemarka near the city of Drammen and in Nordmarka just outside Oslo.
