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) of 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.
