Chicomuceltec (also Chikomuselteko or Chicomucelteco; archaically, Cotoque) is a Mayan language formerly spoken in the region defined by the municipios of Chicomuselo, Mazapa de Madero, and Amatenango de la Frontera in Chiapas, Mexico, as well as some nearby areas of Guatemala. By the 1970s–80s it had become extinct, with recent reports in Mayanist literature finding that there are no living native speakers.
