The Batman River is a major tributary of the Tigris, joining it near the source of Tigris called Dicle River in southeast Turkey. It originates in the Anti-Taurus Mountains (at the Sason and Genç mountains) and flows approximately from north to south, passing near the city of Batman and forming a natural border between the Batman Province and Diyarbakır Province. The historic Malabadi Bridge (built in 1146–1147) crosses the river near the town of Silvan.
