Churchill Falls is a 245 ft (74.7 m) high waterfall on the Churchill River in Labrador, Canada. Formerly counted among the most impressive natural features of Canada, the diversion of the river for the Churchill Falls Generating Station has cut off almost all of the falls' former flow, leaving a small stream winding through its old bed and trickling down the rocks.

The Churchill River, formerly known by other names, is a river in Newfoundland and Labrador, Canada. It flows east from the Smallwood Reservoir into the Atlantic Ocean via Lake Melville. The river is 856 km (532 mi) long and drains an area of 79,800 km2 (30,800 sq mi), making it the longest river in Atlantic Canada.
