The Ravi River is a river in India and Pakistan. It is one of the five rivers which give Punjab its name. The Ravi was known as Parushani or Iravati to Indians in Vedic times and Hydraotes to the Ancient Greeks. It originates in the Himalayas in the Chamba district of Himachal Pradesh following a north-westerly course. It turns to the south-west, near Dalhousie, and then cuts a gorge in the Dhaola Dhar range entering the Punjab plain near Madhopur. It then flows along the Indo-Pak border for some distance before entering Pakistan and joining the Chenab river. The total length of the river is about 720 km. The waters of the Ravi river are allocated to India under the Indus Waters Treaty between India and Pakistan. It is also called 'The river of Lahore' since that great city is located on its eastern bank. On its western bank is located the famous tomb of Jahangir.
