Monte Albán is a large pre-Columbian archaeological site in the Santa Cruz Xoxocotlán Municipality in the southern Mexican state of Oaxaca (17.043° N, 96.767°W). The site is located on a low mountainous range rising above the plain in the central section of the Valley of Oaxaca where the latter's northern Etla, eastern Tlacolula, and southern Zimatlán & Ocotlán (or Valle Grande) branches meet. The present-day state capital Oaxaca City is located approximately 9 km (6 mi) east of Monte Albán.

The partially excavated civic-ceremonial center of the Monte Albán site is situated atop an artificially-leveled ridge, which with an elevation of about 1,940 m (6,400 ft) above mean sea level rises some 400 m (1,300 ft) from the valley floor, in an easily defensible location. In addition to the aforementioned monumental core, the site is characterized by several hundred artificial terraces, and a dozen clusters of mounded architecture covering the entire ridgeline and surrounding flanks (Blanton 1978). The archaeological ruins on the nearby Atzompa and El Gallo hills to the north are traditionally considered to be an integral part of the ancient city as well.
