Axayacatl (; , ; , ; meaning "face of water"; c. 1449-1481) was the sixth tlatoani of the altepetl of Tenochtitlan and ruler of the Aztec Triple Alliance. During his youth, his military prowess gained him the favor influential figures such as Nezahualcoyotl and Tlacaelel I, and thus, upon the death of Moctezuma I in 1469, he was chosen to ascend to the throne, much to the displeasure of his two older brothers, Tizoc and Ahuitzotl. Axayacatl largely dedicated his twelve-year reign to consolidating his militaristic repute: he led successful campaigns against the neighboring altepetl of Tlatelolco in 1473 and the Matlatzinca of the Toluca Valley in 1474, but was finally defeated by the Tarascans of Michoacán in 1476. Despite some subsequent minor triumphs, Axayacatl's defeat at the hands of the Tarascans irreversibly marred his image, as it constituted the only major defeat suffered by the Aztecs up to that moment. In spite of his young age, he fell gravely ill in 1480, passing away a mere year later, in 1481, whereupon he was succeeded by his brother Tizoc.
Axayacatl or āxaxayacatl are the two common names of pre-Hispanic origin used in Mexico to refer to species of aquatic insects in the family Corixidae, the eggs of which, deposited abundantly on rushes (grass-like plants in the Juncaceae family) and flags (species of Iris plant) in lakes and ponds, are collected and sold as a sort of caviar. In addition to eating the insect, the Aztecs also ate the eggs ahuauhtli as part of Aztec cuisine.
