Zhangzhung (Tibetan: ཞང་ཞུང་, Wylie: zhang zhung) is an extinct Sino-Tibetan language that was spoken in Zhangzhung in what is now western Tibet. It is attested in a bilingual text called A Cavern of Treasures (mDzod phug) and several shorter texts.
A small number of documents preserved in Dunhuang contain an undeciphered language that has been called Old Zhangzhung, but the identification is controversial.
