Chang Chenmo River or Changchenmo River is a tributary of the Shyok River, part of the Indus River system. It is at the southern edge of the disputed Aksai Chin region and north of the Pangong Lake basin in Ladakh.
The source of Chang Chenmo is near the Lanak Pass in the Chinese-administered region of Jammu & Kashmir (as part of the Rutog County in Tibet). The river flows west from Lanak La. At the middle of its course lies the Kongka Pass, part of the Line of Actual Control between India and China passes. Continuing west, the river enters a deep gorge in the Karakoram Range until it joins the Shyok River in Ladakh.
