Zenzontepec Chatino, also known as Northern Chatino, or "Chatino Occidental Alto" is an indigenous Mesoamerican language, one of the Chatino family of the Oto-Manguean languages. It is not intelligible with other Chatino languages. It is spoken by one of the most isolated groups in Oaxaca, the Chatino people in the municipalities of Santa Cruz Zenzontepec and San Jacinto Tlacotepec, and in the former municipality of Santa María Tlapanalquiahuitl.
