in northwestern India and northeastern Pakistan, one of the rivers that give the Punjab (meaning “five rivers”) its name. It rises in the Himalayas in Himāchal Pradesh state, India, and flows west-northwest past Chamba, turning southwest at the boundary of Jammu and Kashmir. The river then flows to the Pakistani border and along it for more than 50 miles (80 km) before entering Pakistani Punjab. It flows past Lahore and turns west near Kamālia, emptying into the Chenāb River south of Ahmadpur Siāl after a course of about 450 miles (725 km).

The Rāvi's waters are used for irrigating large areas of land along its course. The Upper Bāri Doāb Canal, with headworks at Mādhopur at the northern tip of Indian Punjab, was completed in 1878–79; it irrigates a large area east of the Rāvi, and its distributary canals extend into Pakistan. The two nations had frequent disputes over the water before reaching an agreement in 1960. The Lower Bāri Doāb Canal, completed in 1917, lies entirely in Pakistan.
