Ladakh (Tibetan alphabet: ལ་དྭགས་, Wylie: la-dwags, Ladakhi [lad̪ɑks], Hindi: लद्दाख़, Urdu: لدّاخ [ləd̪ˈd̪aːx]; "land of high passes") is a region of Jammu and Kashmir, the northernmost state in the control of the Republic of India. It is however disputed territory between Pakistan and India. It lies between the Kunlun mountain range in the north and the main Great Himalayas to the south, inhabited by people of Indo-Aryan and Tibetan descent. It is one of the most sparsely populated regions in Jammu and Kashmir.

Historically, the region included the Baltistan (Baltiyul) valleys, the Indus Valley, the remote Zangskar, Lahaul and Spiti to the south, Aksai Chin and Ngari, including the Rudok region and Guge, in the east, and the Nubra valleys to the north.
