Greenland is in North America. As it is part of the Kingdom of Dennmark, that makes Denmark the third largest nation on the continent by area. Greenland is 836,109 square miles. Mexico is but 761,606 square miles.
Australia is an island larger than Greenland but ( picky picky) is not on the list because it is classified as a continent rather than an island.
