Clarence Lagoon is a coastal lagoon situated along the Beaufort Sea in the far northwestern corner of Canada, within the Inuvialuit Settlement Region near the Alaska border. This remote and dynamic saltwater environment is characterized by its connection to the Arctic Ocean, with its waters and ecology shaped by tidal movements, seasonal ice, and the harsh northern climate. The area holds significant historical and cultural importance as a site of traditional Inuvialuit use and seasonal settlement, now under the management and protection of Parks Canada as part of the national park system.
