Zaachila (the Zapotec name; Nahuatl: Teotzapotlan; Mixtec: Ñuhu Tocuisi) was a powerful Mesoamerican city in what is now Oaxaca, Mexico, 6 km (3.7 mi) from the city of Oaxaca. The city is named after Zaachila Yoo, the Zapotec ruler, in the late 14th and early 15th century. It is now an archaeological site.
