Menissawok National Park was a national park established in 1922 southeast of the town of Maple Creek, Saskatchewan, in the southwest part of the Canadian province.

The 44 km2 (17 sq mi) park land had functioned as a pronghorn reserve beginning in 1914.

Menissawok National Park was one of several national parks created in the Prairies expressly to protect and regenerate dangerously low populations of bison and pronghorn.

The land comprising Menissawok National Park was turned over to the province of Saskatchewan.

While human activity has returned, areas along waterways are covered by trees.
