Tlapacoya is an important archaeological site in Mexico, located at the foot of the Tlapacoya volcano, southeast of Mexico City, on the former shore of Lake Chalco. Tlapacoya was a major site for the Tlatilco culture.

Tlapacoya is known in particular for Tlapacoya figurines. These sophisticated earthware figurines were generally created between 1500 and 300 BCE and are representative of the Preclassic Period.

Tlapacoya was also a manufacturing center for so-called "Dragon Pots" (see photo below). These flat-bottomed cylindrical bowls have white or buff surfaces incised with almost abstract Olmec-style drawings, generally of were-jaguars.
