The Wawa River (Tagalog: Ilog Wawa; Cebuano: Suba sa Wawa) is a river located in Caraga, in northeastern Mindanao, in the southern Philippine island. Its headwaters traverse the municipality of Sibagat, Bayugan, and Esperanza (all of the province of Agusan del Sur). The Wawa River is a tributary of the larger Agusan River.
Wawa came from the Dumagat term that means an "entrance" or "passage". The river was once used by early settlers as a means of transportation during the early years.
The river originates at the Diwata Mountain Range of the northeastern hinterlands of Sibagat in barangays Kolambugan and Padiay and streams traversing the riverbank barangays of Perez, Banagbanag, Santa Cruz, Magsaysay, San Isidro I, Villangit, Poblacion, Tag-uyango, San Vicente, Ilihan (all in the municipality of Sibagat), and barangays Del Carmen (formerly Wawa), Mabuhay, Canayugan, San Agustin, Sagmone, Noli, Maygatasan, Verdu, Salvacion (all in the City of Bayugan) and Mahagkot, Crossing Luna, Dakutan, Bentahon, Piglawigan (all in the municipality of Esperanza) wherein its mouth joins with the larger Agusan River located in Barangay Poblacion, Esperanza, Agusan del Sur.[1]
