What Are the Three Largest Islands in the World?
The World's Three Largest Islands by Area
When ranking islands by total land area, these three stand far above the rest:
-
Greenland (Autonomous territory within the Kingdom of Denmark)
- Area: 2,166,086 km² (836,330 sq mi)
- Located between the Arctic and Atlantic Oceans, northeast of Canada
- Over 80% covered by the Greenland Ice Sheet
-
New Guinea (Divided between Indonesia [Papua & West Papua] and Papua New Guinea)
- Area: 785,753 km² (303,381 sq mi)
- World's second-largest island and highest island (Puncak Jaya, 4,884 m)
- Extraordinary biodiversity and cultural diversity (over 1,000 languages)
-
Borneo (Shared by Indonesia [Kalimantan], Malaysia [Sabah & Sarawak], and Brunei)
- Area: 748,168 km² (288,864 sq mi)
- Third-largest island and largest in Asia
- Home to one of the world's oldest rainforests and endangered species like orangutans
Why Australia Isn't on This List
Australia (7,692,024 km²) is larger than all three combined, but it is classified as a continent rather than an island under standard geographical definitions. If considered an island, it would be the largest.
