Greenland is the largest dependent territory by total area in Wikipedia’s area table. Its total area is about 2,166,086 square kilometres, making it larger than every other dependency listed.
Greenland is geographically part of North America but politically an autonomous territory within the Kingdom of Denmark. It gained home rule in 1979 and expanded self-government in 2009, while Denmark retains responsibility for areas such as foreign policy and defence.
Most of Greenland is covered by the Greenland ice sheet: about 81 percent of its land area lies beneath ice. The ice-free coastal margins contain nearly all settlements, including the capital, Nuuk. Greenland is also the world’s largest island, excluding continents under the usual geographic convention.
Area tables can differ because they may rank total area, land area, or include disputed and special territories differently. French Guiana, New Caledonia, and Puerto Rico are all substantial dependencies or overseas territories, but each is far smaller than Greenland.
