The Mizo language, or Mizo ṭawng, is spoken natively by the Mizo people of Mizoram, a state in the Indian Union, of Chin State in Burma, and in the Chittagong Hill Tracts of Bangladesh. The language is also known as Lushai, a colonial term, as the Lusei tribe was the first to have external exposure. Though still common, Lushai is considered incorrect by the Mizo themselves. Much poetic language is derived from Pawi language, Paite language, and Hmar language, and most known ancient poems considered to be in the Mizo language are in Pawi language.

The Mizo language belongs to the Kukish branch of the Tibeto-Burman family of languages.
