The Grass River is a historically important waterway in the Hudson Bay drainage basin in the Northern Region of Manitoba, Canada. It begins at the Cranberry Lakes approximately 27 kilometres (17 mi) east of Cranberry Portage and runs northeast 500 kilometres (310 mi) to its mouth on the Nelson River. The river was a critical route for earlier European explorers and was part of the "Upper Tract" of the fur trade into Canadian interior.
