The Shyok River (sometimes spelled Shayok) is a major tributary of the Indus River that flows through northern Ladakh in India and into Gilgit-Baltistan in Pakistan. Originating from the Central Rimo Glacier in the eastern Karakoram, it runs for about 550 km (340 mi) before joining the Indus near Skardu. Its major tributaries include the Chip Chap, Galwan, Chang Chenmo, Nubra, and Hushe Rivers.
