Ormtjernkampen National Park () is a former national park located in Gausdal Municipality in Oppland county, Norway. The park was established on 14 June 1968. In 2011, this park was dissolved and its areas were included in the new, much larger Langsua National Park.
During its existence, it was the smallest national park in Norway. It consisted primarily of virgin spruce forest, with some lakes and marshes. It was established to preserve the virgin spruce forest that prevailed in Norway prior to the rise of forestry.
