Yunaska (Aleut: Yunax̂sxa;[1] Russian: Юнаска) is an uninhabited island which is the largest of the Islands of Four Mountains group[2] in the Aleutian Islands of southwestern Alaska, United States. It has a land area of 66.834 square miles (173.099 square kilometres) according to the 2000 census.
The island comprises two volcanic mountains, with a valley between. The western mountain is composed of four overlapping and eroded stratovolcanoes, with a cinder cone field at the western end. It has not been historically active. The eastern mountain is a large shield volcano with two overlapping summit calderas, which last erupted in 1937.
