Sanak Island (Aleut: Sanaĝax) is an island in the Fox Islands group of the Aleutian Islands in the U.S. state of Alaska, located at (54°25′47″N162°42′32″W). Sanak Island and Caton Island are the largest islands in the group of Sanak Islands. Two famous shipwrecks, one in 1906 and another in 1943, occurred near Sanak. Like many of the other Aleutian Islands, Sanak was inhabited by the Aleut people for thousands of years. In 1828, the administrators of Russian America removed the island's population to the Alaska Peninsula in order to preserve the sea otter hunting grounds in surrounding waters.
