Zazacatla is a pre-Columbian archaeological site of Mesoamerica's central Mexican plateau region, in Xochitepec, dating to the mid-Formative period of Mesoamerican chronology. The site was first excavated in 2006 underneath a modern commercial and housing development site, some 13 km (8.1 mi) south of Cuernavaca, capital of the Mexican state of Morelos, and 40 km (25 mi) south of Mexico City. Initial investigations by archaeologists from Mexico's National Institute of Anthropology and History (INAH) reported finding evidence of Olmec cultural influences at the site, the first such known for the western Morelos region.
