Daulat Beg Oldi (also Oldie, DBO) is a traditional campsite and current military base located in the midst of the Karakoram Range in northern Ladakh, India. It is on the historic trade route between Ladakh and Central Asia, forming the last campsite before reaching the Karakoram Pass. It is said to be named after Sultan Said Khan ("Daulat Beg"), who died here on his return journey after an invasion of Ladakh and Kashmir. Chip Chap River, the main headwater of the Shyok River, flows just to the south. The Line of Actual Control with Chinese-controlled Aksai Chin is 5 miles to the east.
