Greenland, one of the largest islands in the world

Largest Islands in the World 🗾

Largest Islands in the World List 🗾 What is an Island?

There is an endless debate about what actually constitutes an island. In theory, the continental landmasses could be considered the worlds biggest 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 which is the biggest island on earth. But it isn’t, so it’s not included in this officially recognized list of the 25 biggest islands in the world.
