Koli National Park (Finnish: Kolin kansallispuisto) is a national park in the municipalities of Joensuu, Lieksa and Kontiolahti in the North Karelia region of Finland. It covers 30 square kilometres (12 sq mi) in the forested hills on the western shore of lake Pielinen, and was established in 1991. Contrary to the other national parks in Finland, Koli National Park was originally governed by the Finnish Forest Research Institute Metla. It is now governed by the Metsähallitus like the other national parks.

Koli has lots to offer cultural heritage-wise. Formerly, it was a sacrificial site. Later it was used for slash-and-burn agriculture. The aim of Koli National Park isn't to reserve wild nature but traditional agricultural heritage is cherished in Koli. Some fields are slashed, burnt and re-cultivated and hay is cut yearly. Traditional Finnish breeds of cows and sheep are grazing in the meadows of Koli.
