The Abatan River is a river in western Bohol, Philippines. The river winds through the towns of Catigbian, Antequera, Balilihan, and Maribojoc to its mouth at Cortes. The river is navigable for up to 19 kilometres (12 mi) for boats drawing 4 ft, and up to 25 kilometres (15.5 mi) for rafts. Its name comes from the word abad which means to meet or to converge. During World War II, a ship in the United States Navy was commissioned: USS Abatan (AW-4), a Pasig-class distilling ship, was named after the river.
