Adugak Island (also spelled Adougakh, possibly from Aleut: Adudak) is a small island in the Fox Islands group in the Aleutian Islands of southwestern Alaska. It is about 1.2 miles (2 km) long and is located 5.0 miles (8 km) off the northwest coast of Umnak Island. The island has been protected as a rookery for the endangered Steller sea lion, which has been observed during the winter feeding on the fish that inhabit the water nearby. The island reaches an elevation of about 102 feet (31 m) above sea level and the area around the island is extremely hazardous to ships because of the numerous rocks that lie just below the surface of the water.
