Greenland, one of the largest islands in the world

Largest Islands in the World

List of the Largest Island in the World – What is an Island?

There is endless debate on what actually constitutes an island. In theory, the continental landmasses could be considered huge islands because they are surrounded by sea. For example, if Australia were to be counted among the largest islands in the world it would easily take first place – because it’s three times bigger than Greenland. But it isn’t, so it’s not included in this list of the 25 biggest, officially recognized, islands on Earth.
