Whitemouth Falls Provincial Park, Provincial park near Seven Sisters Falls, Manitoba, Canada.

Whitemouth Falls Provincial Park covers 4.83 square kilometres where the Whitemouth River joins the Winnipeg River in southeastern Manitoba, about 16 km south of Lac du Bonnet. The land is flat, rising to 273 m above sea level, and mixes farmland with natural vegetation. The Seven Sisters Generating Station, built in 1931, stands on the Winnipeg River and is visible from the park.

Archaeological sites within the park show that people have used this area for about 4800 years. These early settlements reveal the long history of human activity in this region.

The park contains three burial grounds, which are among the archaeological assets recorded within its boundaries. Visitors should treat these sites with respect and leave them undisturbed. The name comes from the Whitemouth River, which meets the Winnipeg River here.

The park lies about 16 km south of Lac du Bonnet, where the Whitemouth River meets the Winnipeg River. The Seven Sisters Generating Station on the Winnipeg River is visible from within the park. Fishing is the main activity, with walleye, lake whitefish and northern pike among the catch; check current Manitoba angling rules before casting.

The 2007 boundary change added 4.3 square kilometres of black spruce and tamarack bog north of the Winnipeg River to protect habitat used by great gray owls; the same change removed 1.21 square kilometres south of the river. The park lies in the Pinawa ecodistrict of the Lake of the Woods ecoregion, part of the Boreal Shield ecozone.
