Yoʼnal Ahk III, also known as Ruler 5, was an ajaw of Piedras Negras, an ancient Maya settlement in Guatemala. He ruled during the Late Classic Period, from 758 to 767 AD. Yoʼnal Ahk III ascended to the throne upon the death of Itzam Kʼan Ahk II, who may have been Yoʼnal Ahk's father. He was succeeded by his probable brother, Haʼ Kʼin Xook in around 767 AD. Yoʼnal Ahk III left behind two surviving stelae at Piedras Negras, namely Stelae 14 and 16, the former of which has been called one of the finest niche stelae, according to Simon Martin and Nikolai Grube.

Itzam Kʼan Ahk II, also known as Ruler 4, was an ajaw of Piedras Negras, an ancient Maya settlement in Guatemala. He ruled during the Late Classic Period, from 729 to 757 AD. Itzam Kʼan Ahk II ascended to the throne following the death of Kʼinich Yoʼnal Ahk II. Itzam Kʼan Ahk II may have fathered the following three kings of Piedras Negras: Yoʼnal Ahk III, Haʼ Kʼin Xook, and Kʼinich Yat Ahk II. Following Itzam Kʼan Ahk II's demise, he was succeeded by Yoʼnal Ahk III in 757 AD. Itzam Kʼan Ahk II left behind several monuments, including stelae at Piedras Negras and a large mortuary temple now known as Pyramid O-13. In addition, the details of his life and his Kʼatun-jubilee were commemorated on Panel 3, raised by Kʼinich Yat Ahk II several years following Itzam Kʼan Ahk II's death.
