The Marikina River (Tagalog: Ilog Marikina) is a river in eastern Metro Manila, Philippines. It is the largest tributary of the Pasig River, with headwaters located in the Sierra Madre Mountains in Rodriguez, Rizal province.
The Marikina River used to be an important transport route during the Spanish colonial era, but its importance as a transport route diminished when the Philippines' national highway system became more established. The resulting lack of river boat traffic and the deforestation of the upland areas in what is now the Upper Marikina River Basin Protected Landscape contributed to the river's siltation, further reducing its value as a transport route.[1]
Due to negligence and industrial development, the river has become very polluted, something that recent Marikina administrations have attempted to address. According to a 2003 pollution report by the Department of Environment and Natural Resources, the Pasig River and Marikina River are both biologically dead.[2]
