Jade Sky (ruled c. 800 – c. 810[1]) was a king of the Maya city-state Quirigua in Guatemala, a successor of Sky Xul, who was maybe a son of great king K'ak' Tiliw Chan Yopaat.
He was the last recorded ruler of Quirigua. The city's power already was waning. Jade Sky did build two of the largest structures in the acropolis, however.[2]
