The Rajang River (Malay: Sungai Batang Rajang) is a river in Sarawak, northwestern Borneo, Malaysia. The river originates in the Iran Mountains, flows through Kapit, and then towards the South China Sea. At approximately 565 km long (351 mi), the river is the seventh-longest in Borneo and the longest in Malaysia.[5][6]
Malaysia's largest and tallest (160m) hydro electric project, the Bakun Hydro Electric Dam, is located on the Balui River, a tributary of the Rajang.[7] Other important tributaries include the Katibas River, Ngemah River, Iran River, Pila River, Balleh River, Bangkit River and the Kanowit River.[5]
