What is the longest river in Malaysia?

The Rajang River is the longest river in Malaysia, stretching approximately 563 kilometers (350 miles). It flows through the central region of Borneo, primarily in the state of Sarawak. The river plays a significant role in the local ecosystem and economy, providing vital transportation routes for people and goods, as well as supporting fishing and agriculture along its banks. Its length and the area it traverses make it a crucial waterway in the region, highlighting its importance in both geographical and cultural contexts.

While Kinabatangan, Perak River, and Sungai Pahang are notable rivers in Malaysia, they do not surpass the Rajang in length. Kinabatangan is known for its rich biodiversity, Perak River is significant for its historical relevance, and Sungai Pahang is important for its economic activities, but none of them match the Rajang River's length. Therefore, identifying the Rajang as the longest river underscores an understanding of Malaysia's geographical features.
