Utian (also Miwok–Costanoan, previously Mutsun) is a family of indigenous languages spoken in the central and north portion of 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 (Callaghan 1997, 2001; Golla 2007:76-77). Utian and Yokutsan have traditionally been considered part of the Penutian language phylum (Goddard 1996:313-319; Mithun 1999; Shipley 1978:82-85).
