Kʼinich Yat Ahk II, also known as Ruler 7, was the last ajaw of Piedras Negras, an ancient Maya settlement in Guatemala. He ruled during the Late Classic Period, from 781 to roughly 808 AD. Possibly a descendant of Itzam Kʼan Ahk II, Kʼinich Yat Ahk II ascended the throne upon the death of his brother, the sixth ajaw of the site, Haʼ Kʼin Xook. While Kʼinich Yat Ahk II presided over the destruction of the rival Maya site Pomona, his reign likely ended with Kʼinich Tatbu Skull IV of Yaxchilan capturing and subjugating Piedras Negras. Itzam Kʼan Ahk II left behind several monuments, including stelae at Piedras Negras, a stone seat known as Throne 1 which records either the death or abdication of Haʼ Kʼin Xook, and Panel 3 which recounts the exploits of Itzam Kʼan Ahk II.

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.
