Børgefjell National Park is an undeveloped national park in Norway, straddling the border between Trøndelag and Nordland counties, along the border with Sweden. The park is undeveloped with few trails or other facilities for visitors. Visitors can hike for extended periods without seeing another person. The 1,447-square-kilometre park was originally established in 1963, and it was enlarged in 1973 and 2003.
