San Lorenzo Zinacantán is a town and municipality in the Mexican state of Chiapas in southern Mexico. 99.1% of its population is Tzotzil Maya, an indigenous people with linguistic and cultural ties to other highland Maya peoples.

Chiapas is a state in Southwest Mexico. According to the 2020 Mexican census, it has the eighth largest population of all states with 5,543,828 inhabitants and the 10th largest by land area spanning 73,560.47 square kilometres (28,401.86 sq mi). Chiapas is officially divided into 124 municipalities, although the establishment of municipal authorities in Belisario Domínguez was suspended in 2015 pending the resolution of a territorial dispute between Chiapas and the neighbouring state of Oaxaca. In 2021, the Mexican Supreme Court resolved this dispute in Oaxaca's favour, and annulled the 2011 decree that had created Belisario Domínguez.
