Borneo (/ˈbɔːrnioʊ/; Indonesian: Kalimantan, Malay: Borneo) is the third-largest island in the world and the largest island in Asia. At the geographic center of Maritime Southeast Asia, in relation to major Indonesian islands, it is located north of Java, west of Sulawesi, and east of Sumatra.
The island is divided among three countries: Malaysia and Brunei in the north, and Indonesia to the south. Approximately 73% of the island is Indonesian territory. In the north, the East Malaysian states of Sabah and Sarawak make up about 26% of the island. Additionally, the Malaysian federal territory of Labuan is situated on a small island just off the coast of Borneo. The sovereign state of Brunei, located on the north coast, comprises about 1% of Borneo’s land area. Antipodal to an area of Amazon rainforest, Borneo is itself home to one of the oldest rainforests in the world.
