In Aztec mythology, Mexitli () is a deity who was sometimes identified with the war god Huëtzilà Âpà Âchtli. "Mexitli" is described by some sources as an alternative name of Huëtzilà Âpà Âchtli, or as the origin of the name "Mexicans". One scholar believes that Mexitli was originally an earth deity of the Mexican people before their founding of Tenochtitlan, and another views him as a leader of the early Mexicans who was identified with Huëtzilà Âpà Âchtli.
In the Historia de los Indios de la Nueva España of Toribio de Benavente (1482–1565), Mexitli is described as the chief Aztec deity, from whom the words "Mexico" and "Mexicans" are derived, also known by the name "Texatlicupa". In his Memoriales, Benavente uses "Mexitli" as an alternative name for Huëtzilà Âpà Âchtli; according to Doris Heyden, in doing so he identifies Mexitli, Huëtzilà Âpà Âchtli, and Tezcatlipoca. Tomás de Torquemada (1420–1498), in his MonarquÃÂa indiana, also writes that "Mexitli" was another name for Huëtzilà Âpà Âchtli, interpreting the former as "the navel of the maguey". Francisco Javier Clavijero (1731âÂÂ1787) derives the name of the Mexicans from Mexitli, and – according to – interprets him as "a kind of cryptonym for the Aztec tribal god". The Nahuatl text which contains the Leyenda de los Soles () instead describes Meçitli as female earth deity, who rears the young Mixcoa.
believes that Huëtzilà Âpà Âchtli was originally a Toltec god, and was not worshipped by the early Mexican people until their founding of Tenochtitlan; he sees Mexitli, whom he describes as a god of the earth, as one of their deities prior to the adoption of Huëtzilà Âpà Âchtli. After this early period, he considers Mexitli to be Huëtzilà Âpà Âchtli in the form of an earth deity.
According to Javier Rondero, Mexitli was the leader of the Mexicans during their migration to Mexico, also known as Mexi and Mixi, who was deified and assimilated to Huëtzilà Âpà Âchtli in the region of Michoacán. He sees his name as meaning "the one who kills (with an obsidian arrow)", thereby signifying "the lord of death and war". Gutierre Tibón writes that Mexitli was an eponymous, mythical hero who was equated with Huëtzilà Âpà Âchtli, comparing this to the identification of Romulus with the deity Quirinus.<reF>Tibón, p. 227.</ref>
