What is the largest non-continental island in the world?

Greenland is considered the largest noncontinental island in the world due to its size and geographical characteristics. Although politically part of the Kingdom of Denmark, Greenland is an autonomous territory located in the North Atlantic Ocean. Spanning roughly 2,166,086 square kilometers, it has a massive land area, making it larger than other prominent noncontinental islands such as New Guinea and Borneo. Its immense size and distinct landmass formation contribute to Greenland being recognized as the largest noncontinental island in the world.
