The Suru River is a tributary of the Indus River that flows largely through the Kargil district of Ladakh, India into Gilgit-Baltistan in Pakistan. The Suru Valley is coextensive with the Kargil tehsil, with the town of Kargil situated on its banks. The river enters the Kharmang District of Gilgit-Baltistan, coursing a brief length before joining the Indus near Marol.
