Rusty Creek[1] is a river in the Canadian province of Saskatchewan.

It is a south flowing river and the entirety of its course is in Meadow Lake Provincial Park[2] and the boreal forest[3] ecozone.

Rusty Creek is a tributary of Waterhen River, which is a major tributary of Beaver River of the Churchill River and in the Hudson Bay drainage basin.

While Rusty Creek itself is relatively short, it has a comparatively large drainage basin that has its roots in the Mostoos Hills[4] north of Meadow Lake Provincial Park.

Rusty Lake is along the course of Rusty Creek and numerous creeks flow into the lakes including Dennis Creek,[5] which flows into First Mustus Lake.
