Tres Zapotes is a Mesoamerican archaeological site located in the south-central Gulf Lowlands of Mexico in the Papaloapan River plain. Tres Zapotes is sometimes referred to as the third major Olmec capital, but the Olmec phase is only a portion of the site's history, which continued through the Epi-Olmec and Classic Veracruz cultural periods.

Mesoamerica is a historical region and cultural area that begins in the southern part of North America and extends to the Pacific coast of Central America, thus comprising the lands of central and southern Mexico, all of Belize, Guatemala, El Salvador, and small parts of Honduras, Nicaragua and Costa Rica. As a cultural area, Mesoamerica is defined by a mosaic of cultural traits developed and shared by its indigenous cultures.
