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. Since 2012, China has disputed the border region situated to the south and southeast of Chumur village within the Chumur sector. However, the Chumur village itself is undisputed and remains in India. The Indian border post at Chumur Peak, offering a view of disputed grazing lands, lies approximately 15-20 km to the south/southwest of Chumur village. In contrast, the Chinese post at Chepzi hamlet is situated 8-10 km south of Chumur village, directly opposite the Indian positions on Chumur Peak. Both Chumur village, nestled in a side valley along the Chumur Tokpo stream (a tributary of the Pare Chu river), and Chepzi are located along the course of the Pare Chu river.
Chumar is reachable from east (Hanle and Demchok), north/northwest (Tso Moriri, Karzok, Meroo, Ryul, and Leh), and west/southwest (Kiato, Kaza, Tabo, and Shimla) from the Meroo-Ryul-Hanle-Chumur-Karzok-Kiato road network (including the 125 km long Kiato-Karzok Road from Spiti Valley via Takling La Tunnel).
