Durbuk or Darbuk,[a] is a village and the headquarters of the eponymous subdivision and block in the Leh district of Ladakh, India.

[6][7] It is located in the Durbuk tehsil, and falls between Chang La mountain pass and Tangste village on the way to Pangong Tso Lake.

The trade routes to Yarkand (via the Shyok Valley) as well as Rudok (via the Pangong Lake) passed through here.

[3] In historical sources Durbuk is sometimes referred to as "Dumra" (Ldum-ra or Nubra), which is really the name of the Shyok River valley.

The stretch between Shyok and DBO is also called Sub-Sector North (SSN) by the Indian Military, and is off-limits to civilians.
