The Ratuwa River (Nepali: रतुवा खोला) is a perennial river located in eastern Nepal. Originating from the Chure Pahad, it flows southward through the Terai region, forming the eastern boundary of Damak Municipality, before crossing into India, where it merges with the Kankai River in Bihar. The river plays a significant role in the region's ecosystem, agriculture, and urban life but faces challenges related to environmental degradation and flood risks.
