Bunan, also known as Gahri, Ghara, Lahuli of Bunan, Boonan, Punan, Poonan, Erankad or Keylong Boli, is a Tibeto-Burman minority language, largely spoken in the Keylong block of Lahaul and Spiti district, in the northernmost region of Himachal Pradesh, India.

The Tibeto-Burman language family consists of fourteen languages spoken in Himachal Pradesh and Uttarakhand, and Bunan is assigned to the West Himalayish branch.

[2][3] The Endangered Languages Project classifies it as a ‘threatened’ language due to the changing economic landscape of the Lahaul region and the migration of Bunan speakers to other areas of the country, especially the younger generation migrating for education and employment.

[7] Other commonly spoken languages of the Bunan community are Hindi, Tibetan, Manchad, and English.

Bunan is also spoken in Barbog, Bokar Gompa, Billing, Chhelling, Gozang, Greimas, Gumlink, Gumrang, Gyuskhar, Lepchang, Katchra, Kardang, Kardang Gompa, Mongwan, Mangmore, Namchia, Paspara, Pyaso, Pyukar, Sasure Gompa, Sikkeling, Styingri, Tayule, and Yurnad regions.
