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 recently extinct, with the last native speaker dying in 2025, down from 25 native speakers in 1997; nevertheless there are revitalization programs.
