Lake Melville is an estuary of Hamilton Inlet (itself an extension of Groswater Bay) on the Labrador coast of the Canadian province of Newfoundland and Labrador. Comprising 3,069 km2 and stretching 140 km inland to Happy Valley-Goose Bay, it forms part of the largest estuary in the province, primarily draining the Churchill River and Naskaupi River watersheds. Both Lake Melville and Hamilton Inlet are encircled by mountains, with primary settlements at Happy Valley-Goose Bay, North West River, and Sheshatshiu. It is the 46th largest lake globally.
