Salamajärvi National Park (Finnish: Salamajärven kansallispuisto) is a national park in the Central Ostrobothnia and Central Finland regions of Finland. It is located in the municipalities of Perho, Kivijärvi, and Kinnula. The park is found in the rough and rocky watershed area of Suomenselkä. This large area has no people living there and is famous for its many wetland areas and the variety of wild animals that live there.

The park has about 60 kilometers (37 miles) of marked trails. Many of the trails are difficult to walk on because of the rocky ground, but some trails are easy to walk on and are good for children.
