Tsotsil or Tzotzil is a Mayan language spoken in the Mexican state of Chiapas by about 330,000 people. It is closely related to Tzeltal and Ch'ol and is part of the Cholan-Tzeltalan branch of the Mayan language family.
Tzotzil has six dialects which are named after the different regions of Chiapas in which they are spoken: Chamula, Zinacantán, San Andrés Larráinzar, Huixtán, Ch'enalho', and Venustiano Carranza. There is varying degrees of mutual intelligibility between them.
Tzotzil is used as a medium in instruction in some primary and secondary schools in central Chiaps.
