Lamandau River (Indonesian: Sungai Lamandau) is a river of Kalimantan, southern-central Borneo, Indonesia. Downstream after passing the village of Nanga Bulik it becomes the Kotawaringin River.
The ancient town of Kotawaringin is located in the valley formed by the river and its tributary along with gold and gemstone mining areas. In the upper reaches of the tributary valley of Arut River the Pangkalan Bun town flourishes on its banks.
