The Barito River is the second longest river in Borneo after the Kapuas River with a total length of 1,090 km (680 mi) and a drainage basin of 81,675 square kilometers (31,535 sq mi) in South Kalimantan, Indonesia. It originates in the Muller Mountain Range, from where it flows southward into the Java Sea. Its most important affluent is the Martapura River, and it passes through the city of Banjarmasin.

This river is the location of the closest relative of the Malagasy language of Madagascar, the Ma'anyan language of Dayaks, from where settlers arrived in Madagascar (presumably in waves) from the 3rd to 10th century and from which the current island nation's population largely traces its origins.
