Tenayuca is a pre-Columbian Mesoamerican archaeological site in the Valley of Mexico. In the Postclassic period of Mesoamerican chronology, Tenayuca was a settlement on the former shoreline of the western arm of Lake Texcoco. It was located approximately 10 kilometres to the northwest of Tenochtitlan.
Tenayuca is considered to be the earliest capital city of the Chichimec, nomadic tribes who migrated and settled in the Valley of Mexico, where they formed their own empire.
