Chenab River is a major river that flows in India and Pakistan.

It is formed by the union of two headwaters, Chandra and Bhaga, which rise in the upper Himalayas in the Lahaul region of Himachal Pradesh, India. 

The Chenab flows through the Jammu region of Jammu and Kashmir into the plains of Punjab, Pakistan, before ultimately flowing into the Indus River.

The waters of the Chenab were allocated to Pakistan under the terms of the Indus Waters Treaty. India is allowed non-consumptive uses such as power generation.
