Acatitlan (Nahuatl: "place among the reeds"; Spanish "carrizal") is an archeological zone of the early Aztec (or Epi-toltec) culture located in the town of Santa Cecilia, in the municipality of Tlalnepantla de Baz in Mexico State, about 10 km northwest of Mexico City. In pre-Hispanic times it was located on the northwest shore of the great Lake Texcoco.

Parish of Santa Cecelia Acatitlan built partially with materials from the destroyed pyramid.
This settlement was associated with Tenayuca, the political and religious center of the time; the two sites are about 3 km apart. Along with Tenayuca, it was later annexed by the Mexica and became part of the lacustrine culture of the Valley of Mexico under the rule of Tenochtitlan, until the arrival of the conquistadors in 1521. After the conquest of Mexico, Acatitlan began to decline, and the city, like many other Mesoamerican structures, was destroyed so its stone could be used to construct Christian churches.
