Iloilo River

The Iloilo River is an estuarine river located in the southeastern part of the province of Iloilo, in Western Visayas, Philippines. The river starts in Oton at the Batiano estuary, then traverses through the Iloilo Citydistricts of Arevalo, Molo, Mandurriao, La Paz, Lapuz, and the City Proper, before emptying into the Iloilo Strait.

As an estuary, the river level fluctuates with the tides. This flow brings in nutrients from the sea, which makes the Iloilo River a nursery for fish species such as bangus and tilapia. The banks of the river are home to 22 of the country's 35 mangrove species, as well as the rare metapenaeus insolitus.
