Tlatelolco (sometimes also called Xaltelolco) was a pre-Columbian Nahua altepetl (town, city) in the Valley of Mexico. Its inhabitants were known as Tlatelolca. The Tlatelolca were a part of the Mexica ethnic group, a Nahuatl speaking people who arrived in what is now central Mexico in the 13th century. They settled on an island in Lake Texcoco where they founded their city on the northern part — the other Mexica group, the Tenochca, founded their city Tenochtitlan on the southern part. The city was closely tied with its sister city, which was largely dependent on the market of Tlatelolco, the most important site of commerce in the area.

The Tlatelolco archaeological site is an archaeological excavation site in Mexico City, where the remains of the pre-Columbian citystate of Tlatelolco have been found. It is centered on the Plaza de las Tres Culturas, a square surrounded on three sides by an excavated Aztec site, a 17th-century church called Templo de Santiago, and the modern office complex of the Mexican foreign ministry. In February 2009, the discovery of a mass grave with 49 human bodies was announced by archaeologists. The grave is considered unusual because the bodies are laid out in ritual fashion.

Tlatelolco is an archaeological excavation site in Mexico City, Mexico where remains of the pre-Columbian city-state of the same name have been found. It is centered on the Plaza de las Tres Culturas, a square surrounded on three sides by an excavated Aztec site, a seventeenth-century church called the Templo de Santiago, and the modern office complex formerly of the Mexican Foreign Ministry and since 2005 of the Centro Cultural Universitario of UNAM.

The main temple of Tlatelolco, one of the excavated buildings recently saw the discovery of a pyramid inside the visible temple which is more than 700 years old. This indicates that the site is older than previously thought, according to Instituto Nacional de Antropología e Historia (National Institute of Anthropology and History; INAH). Because it has design features similar to pyramids found in Tenayuca and Tenochtitlan, it may prove to be the first mixed Aztec and Tlatelolca construction found.
