Utian languages

Utian (also Miwok–Costanoan, previously Mutsun) is a family of Indigenous languages spoken in Northern California, United States. The Miwok and Ohlone peoples both spoke languages of the Utian language family. It has recently been argued that the Utian languages and Yokuts languages are sub-families of the Yok-Utian language family. Utian and Yokutsan have traditionally been considered part of the Penutian language phylum.

All Utian languages are severely endangered.
