Cartwright is a community located on the eastern side of the entrance to Sandwich Bay, along the southern coast of Labrador in the province of Newfoundland and Labrador, Canada. It was incorporated in 1956.
Cartwright has been a settled community since 1775 when Captain George Cartwright, for whom the place is named, settled there, establishing a fish and fur trading business. Eleven years later he left Labrador, maintaining a business interest there until it was sold to Hunt and Henley in 1815. It was again sold in 1873 to the Hudson's Bay Company and has remained under company ownership ever since.
Since 2002, Cartwright has been connected by road (a section of the Trans-Labrador Highway) with Blanc Sablon, Quebec, where there is a car ferry to Newfoundland. In summer it is also connected by car ferry to Goose Bay, Labrador and Lewisporte, Newfoundland.
