Caddo (endonym: Hasí꞉nay, pronounced [hasí:naj]) is a Caddoan language indigenous to the Southern United States and the traditional language of the Caddo Nation. It is critically endangered, with no exclusively Caddo-speaking community and as of 2023 only two speakers who had acquired the language as children outside school instruction, down from 25 speakers in 1997. Caddo has several mutually-intelligible dialects. The most commonly used dialects are Hasinai and Hainai; others include Kadohadacho, Natchitoches and Yatasi.
