Rajang RiverAbout Rajang River
The Rajang River is a major river in the Malaysian state of Sarawak on the island of Borneo and is the longest river in that state. It has been a primary inland artery for transport, commerce and settlement in central Sarawak.
Along its course the river passes towns and settlements that rely on river transport; boat travel and riverine villages are common features. The river corridor is used for passenger and cargo movement and provides access to remote interior communities.
The Rajang has long been central to the livelihoods of indigenous communities and later to colonial and post-colonial timber and trade operations, which made extensive use of the river as a transport route. It has shaped regional settlement patterns and local economies for centuries.
The river flows across central Sarawak from its upland headwaters toward the South China Sea, passing towns such as Sibu on its lower reaches. It drains a large interior basin and connects inland areas with coastal ports.
- Length and importance: At about 563 kilometres in length, it is the longest river in the Malaysian state of Sarawak and a major inland transport route.
- Major town on the river: The town of Sibu is the principal urban centre on the river and a regional commercial hub.
