Nistowiak Falls, at 10 metres (33 ft), is one of the highest waterfalls in the province of Saskatchewan, Canada.

Nistowiak is a Cree word referring to the convergence of waters.

From Stanley Mission, it is about 20 kilometres (12 mi) east by water on the Churchill River.

The trail to the falls goes through the fishing camp for part of the way.

Lac la Ronge drains into the Churchill River through these falls.
