Balti (Nastaʿlīq script: , Tibetan script: སྦལ་ཏི།, ) is a Tibetic language natively spoken by the ethnic Balti people in the Baltistan region of Gilgit−Baltistan, Pakistan, Nubra Valley of the Leh district and in the Kargil district of Ladakh, India. The language differs from Standard Tibetan; many sounds of Old Tibetan that were lost in Standard Tibetan are retained in the Balti language. It also has a simple pitch accent system only in multi-syllabic words while Standard Tibetan has a complex and distinct pitch system that includes tone contour.
Balti is spoken in most parts of Gilgit-Baltistan in Pakistan, Kargil and Nubra Ladakh in India. According to the Gilgit-Baltistan Scouts, Balti is mostly spoken in Skardu, Shigar, Gultari, Ghanche, Roundu and Kharmang parts of Gilgit-Baltistan. In the twin districts of Ladakh region (Kargil and Leh) it is spoken in Kargil city and its surrounding villages like Hardass, Lato, Karkitchhoo and Balti Bazar and in Leh – Turtuk, Bogdang, Tyakshi including Leh city and nearby villages. Balti language is also spoken by Balti immigrants in Karachi, Lahore, Peshawar, Islamabad, Quetta and other cities of Pakistan. In India it is spoken in Dehradun, Nainital, Ambari, Shimla, Vikasnagar and other cities of Northern India by immigrants who have migrated from Baltistan, Kargil, and Nubra before the partition of India and Pakistan.
