Borneo is the third-largest island in the world and the largest island of Asia. At the geographic centre 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: Brunei and Malaysia on the north, and Indonesia to the south. Approximately 73% of the island is Indonesian territory. In the north, the Malaysian states of Sabah and Sarawak, along with the federal territory of Labuan, make up about 26% of the island. The sovereign state of Brunei, located on the north coast, comprises about 1% of Borneo's land area. Borneo is home to one of the oldest rainforests in the world.
