Seitseminen National Park (Finnish: Seitsemisen kansallispuisto) is located in the municipalities of Ikaalinen and Ylöjärvi in Finland.

The park is a typical mix of upland and lowland coniferous boreal forests of the Suomenselkä watershed region.

These swamp and bog areas appear to be barren due to the sparse tree densities.

Parts of the park contain some of the most ancient and oldest forests that are accessible to public in Finland.

Seitseminen National Park received the European Diploma of Protected Areas on 19 June 1996.
