Coxcoxtli (modern Nahuatl pronunciationⓘ) was a king of city-state Culhuacán.
He had two children — a son called Huehue Acamapichtli and a daughter Atotoztli I,[1] who married Opochtli Iztahuatzin and bore him Acamapichtli, the first ruler of Tenochtitlan.
He was thus an ancestor of Aztec emperors.
