Chumar or Chumur (Tibetan: ཆུ་མུར་, Wylie: chu mur) is a village located in south-eastern region of Ladakh, India and the centre of nomadic grazing.

It is in Rupshu block, south of the Tso Moriri lake, on the bank of the Parang River (or Pare Chu), close to Ladakh's border with Tibet.

[5] The Chumar settlement itself is in a side valley of Pare Chu, on the bank of a stream, called Chumur Tokpo that flows down from Mount Shinowu.

[6] Along the course of Pare Chu and its tributary streams are numerous pastures and campgrounds utilised by the pastoral nomads of Rupshu.

The Chepzilung originates below the Gya Peak, a key point on the border between Spiti (Himachal Pradesh) and Tibet.

[7] According to the map drawn by Frederic Drew, who worked as a geologist in the administration of Jammu and Kashmir, these two tributaries were border rivers of Ladakh.

The combined effect of these decisions gave the appearance of a "bulge" in Indian territory near the Pare Chu river.

The Indian government justified it on the grounds that the Ladakh's inhabitants had traditionally used the grazing lands along Pare Chu right up to Chepzi.

(Map 3) Chumar has been one of the most active areas on the Line of Actual Control (LAC) in terms of interactions between Chinese and Indian troops.
