Ixtlilxochitl Ome Tochtli (c. 1380-1418) was the ruler (tlatoani) of the Acolhua city-state of Texcoco from 1409 to 1418 and the father of the famous "poet-king" Nezahualcoyotl.

Claiming descent from the legendary Chichimec chieftains King Xolotl and Nopaltzin, Ixtlixochitl became tlatoani of Texcoco in 1409 after the death of his father, Techotlala.

For several years thereafter, Ixtlilxochitl continued to pay tribute to the powerful Tepanec city of Azcapotzalco and its tlatoani Tezozomoc.

The following year, the Tepanec forces, including Mexica contingents, again laid siege to Texcoco this time driving out Ixtlilxochitl, who was finally cornered in the foothills of Mount Tlaloc.

Ten years later Nezahualcoyotl would avenge his father's death and retake Texcoco with the help of Itzcoatl, the future tlatoani of Tenochtitlan.
