Chiapas Zoque is a dialect cluster of Zoquean languages indigenous to southern Mexico (Wichmann 1995).
The three varieties with ISO codes, Francisco León (about 20,000 speakers in 1990), Copainalá (about 10,000), and Rayón (about 2,000), are named after the towns they are spoken in, though residents of Francisco León were relocated after their town was buried in the eruption of El Chichón Volcano in 1982.
[4] There are about 15,000 speakers of Chiapas Zoque, although the number is rapidly decreasing (Faarlund 2012:3).
The vast majority of speakers reside in Tapalapa, Ocotepec, and Pantepec.
Before the publication of Jan Terje Faarlund's A Grammar of Chiapas Zoque (2012), the best documented Chiapas Zoque variety has been that of Copainalá due to the work of William Wonderly and other scholars.
