Nezahualpilli (Nahuatl for "fasting prince"; 1464–1515, modern Nahuatl pronunciationⓘ) was king (tlatoani) of the Mesoamerican city-state of Texcoco, elected by the city's nobility after the death of his father, Nezahualcoyotl, in 1472.

Nezahuapilli's mother was Azcalxochitzin, who married Nezahualcoyotl after the death of her first husband, King Cuahcuauhtzin of Tepechpan.

[1] Like his father, he was a poet, was considered a sage, and had the reputation of being a fair ruler.

During his reign, he abolished capital punishment for a number of crimes and struggled to keep the political independence of Texcoco during the increasing centralization of Aztec power in Tenochtitlán.

[2] When he told Moctezuma II that the Texcocan wise men had foretold foreign dominion over the Valley of Mexico, the emperor challenged him to a ball game.
