There is no known established Ainu language word for the island of Hokkaido. However, the Ainu people did have a name for all of their domain, which included Hokkaido along with the Kuril Islands, Sakhalin, and parts of northern Honshu, which was "Aynu Mosir" (), a name taken by the modern Ainu to refer to their traditional homeland. "Ainu Mosir" literally translates as "The Land Where People (the Ainu) Live", and it was traditionally used to be contrasted with "Kamuy Mosir", "The Land of the Kamuy (spirits)".
