"Spearthrower Owl" is the name commonly given to a Mesoamerican personage from the Early Classic period, who is identified in Maya inscriptions and iconography. Mayanist David Stuart has suggested that Spearthrower Owl was a ruler of Teotihuacan at the start of the height of its influence across Mesoamerica in the 4th and 5th century, and that he was responsible for an intense period of Teotihuacan presence in the Maya area, including the conquest of Tikal in 378 CE.
