(September 11, 600 – 680s), known as Yuknoom the Great, was a Maya ruler of the Kaan kingdom, which had its capital at Calakmul during the Classic Period of Mesoamerican chronology.

[citation needed] As he acceded in AD 636 and his successor followed him upon the throne in 686, Yuknoom the Great is known to have ruled the Kaan kingdom for fifty years during the height of its power and ascendency over Tikal.

But then in 672 the Tikal king asserted his independence by ousting Bajlaj Chan Kʼawiil from Dos Pilas and pursuing him as he sought refuge at other sites.

Retribution seems to have followed swiftly, however, as the royal lineage of Naranjo was terminated within two years, ultimately to be replaced by the grandson of Bajlaj Chan Kʼawiil.

Yuknoom Chʼeen's superordinate status was recognized in inscriptions at a number of sites, while it is probable that a great many other such mentions are lost to us.
