Tangtse, also known as Drangtse, is a village situated in the Leh district of Ladakh, India. It is located in the Durbuk tehsil, at an altitude of 12,500 feet. Tangtse is a sparsely populated village with a population of about 700 people. The majority of the population is Buddhist and speaks Ladakhi.
Tangtse is a well-known and important site of Tocharian, Sogdian, Śārāda and Arabic inscriptions. A Franco-Indian Archaeological Mission in Ladakh called the rock art at Tangste as "the most important" site for rock art in Ladakh, providing information about Ladakh towards the end of the 1st millennium AD. The mission found "about 300 petroglyphs" and "almost 70 rock inscriptions in various scripts".
Tangtse was a key halting place on the trade route between Turkestan and Tibet. It was also a site of wars between Ladakh and Tibet.
Tangtse is also home to several monasteries, including the Spituk Monastery, which is one of the oldest and most important monasteries in Ladakh.
