The Calumpang River (Tagalog: Ilog Calumpang) is a major river in eastern Batangas, Philippines. Known as the "Nile of Batangas," the river itself forms the southeastern boundary of Poblacion, Batangas City as it continues to flow southward to Batangas Bay at an approximately point of 2 kilometres (1.2 mi) east of Batangas Port.

The river may derive its name from Sterculia foetida, a tree which whose local name is alternately spelled calumpang or kalumpang in Tagalog.
