Quetzalcoatl ; is a Mesoamerican deity whose name comes from the Nahuatl language and means "feathered serpent". The worship of a feathered serpent is first known documented in Teotihuacan in the first century BC or first century AD. That period lies within the Late Preclassic to Early Classic period (400 BC – 600 AD) of Mesoamerican chronology, and veneration of the figure appears to have spread throughout Mesoamerica by the Late Classic (600–900 AD).

1915 Quetzalcóatl, provisional designation 1953 EA, is a very eccentric, stony asteroid classified as near-Earth object, about half a kilometer in diameter. It was discovered by American astronomer Albert Wilson at Palomar Observatory, California on March 9, 1953.
