"Spearthrower Owl" (or
Atlatl Cauac) (? – 439 AD) is the name commonly given to a
Mesoamerican personage from the
Early Classic period, who is identified in
Maya inscriptions and iconography. It has been suggested that Spearthrower Owl was a ruler of
Teotihuacan at the start of height of its influence across Mesoamerica in the 4th and 5th century, and that he was responsible for the introduction of Teotihuacan-related cultural traits in the Maya area.
