K'inich Janaab Pakal I (Mayan pronunciation: [k’ihniʧ xanaːɓ pakal], also known as Pacal, Pacal the Great, 8 Ahau and Sun Shield, (March, 603 - August, 683) was ajaw of the Maya city-state of Palenque in the Late Classic period of pre-Columbian Mesoamerican chronology. He acceded to the throne in July 615 and ruled until his death. During a long reign of 68 years, the longest known regnal period in Western Hemisphere history, and the 30th longest worldwide, Pakal was responsible for the construction or extension of some of Palenque's most notable surviving inscriptions and monumental architecture.

Before his name was securely deciphered from extant Maya inscriptions, this ruler had been known by an assortment of nicknames and approximations, including Pakal or Pacal, Sun Shield, 8 Ahau, and (familiarly) as Pacal the Great. The word pakal means "shield" in the Classic Maya language.

In modern sources his name is also sometimes appended with a regnal number, to distinguish him from other rulers with this name, that either preceded or followed him in the dynastic lineage of Palenque. Confusingly, he has at times been referred to as either "Pakal I" or "Pakal II". Reference to him as Pakal II alludes to his maternal grandfather (who died c.612) also being named Janahb Pakal. However, although his grandfather was a personage of ajaw ranking, he does not himself appear to have been a king. When instead the name Pakal I is used, this serves to distinguish him from two later known successors to the Palenque rulership, K'inich Janaab Pakal II (ruled c. 742) and Janaab Pakal III, the last-known Palenque ruler (ruled c.799).
