Burushaski (; Burushaski: بُرُشَسکݵ‎, romanized: burúśaski, IPA: [bʊˈruːɕʌskiː]) is a language isolate, spoken by the Burusho people, who predominantly reside in the northern Gilgit-Baltistan, Pakistan. There are also a few hundred speakers of this language in the northern Jammu and Kashmir, India. In Pakistan, Burushaski is spoken by people in the Hunza District, the Nagar District, the northern Gilgit District, the Yasin Valley in the Gupis-Yasin District and the Ishkoman Valley of the northern Ghizer District. Their native region is located in northern Gilgit–Baltistan. It also borders with the Pamir corridor to the north. In India, Burushaski is spoken in Botraj Mohalla of the Hari Parbat region in Srinagar. It is generally believed that the language was spoken in a much wider area in the past. It is also known as Werchikwar and Miśa:ski.

Due to the effects of dominant languages in Pakistani media, such as Urdu, Standard Punjabi and English, and the religious impact of Arabic and Persian, Burushaski, like other languages of Pakistan, is continuously expanding its vocabulary with loanwords.
