This list of islands by area includes all islands in the world greater than 2,500 km2 (970 sq mi) and several other islands over 500 km2 (190 sq mi), sorted in descending order by area. For comparison, continents are also shown.

Continental landmasses
Although the continental landmasses listed below are not normally called islands (by definition a landmass cannot be both an island and a continent), they are, in fact, land entirely surrounded by water. In effect, they are enormous islands and are shown here for that reason. The figures are approximations and are for the continental mainland only.
Islands (18 total) 100,000 km2 (39,000 sq mi) and greater
Although an island is, in general, any land mass that is completely surrounded by water, some definitions exclude land masses large enough to be considered continents. Placing Australia in the latter category makes Greenland the largest island.
Islands (142 total) 1,000–2,499 km2 (386–965 sq mi)
This section of the list might not be complete, but covers almost all of the islands in the world over 1,000 km2 (390 sq mi). The area of some Antarctic islands is uncertain.
Islands (188 total) 500–999 km2 (193–386 sq mi)
This section of the list is not complete, although it should cover all European islands over 500 km2 (190 sq mi) and most islands of other continents.
