Tepehuán (Tepehuano, Tepecano) is the name of three closely related languages of the Piman branch of the Uto-Aztecan language family, both spoken in northern Mexico. The language is called O'otham by its speakers.
Northern Tepehuán is spoken by about 8,000 Tepehuán people (2005 census) in the south of the state of Chihuahua and north of Durango.
Southern Tepehuán is divided into the southeastern and southwestern group.
The extinct Tepecano language appears to have been a variety of Southern Tepehuán.
Tepehuán-language programming is carried by the CDI's radio stations XEJMN-AM, broadcasting from Jesús María, Nayarit, and XETAR, based in Guachochi, Chihuahua.
