Eduardo Núñez

José Eduardo Núñez Navarro (born July 25, 1997) is a Mexican professional boxer who held the International Boxing Federation (IBF) junior-lightweight title from 2025 to 2026.

Professional career Núñez turned professional in 2015 after just five amateur bouts, compiling a record of 27–1 before facing Masanori Rikiishi for the vacant IBF super-featherweight title. Núñez entered the fight with a 100% knockout-to-win ratio, with his one defeat at that point being his only fight that had gone the distance. Said defeat came against Hiram Gallardo, who defeated Núñez via unanimous decision on account of a point deduction in the third round for low blows (without the deduction, the bout would have been a unanimous draw). This was the 11th bout of his career.

After 12 rounds, Núñez won by unanimous decision, his second fight to go the distance and his first decision victory.

Núñez vs. Diaz Núñez made the first defense of his IBF junior lightweight title against Christopher Díaz at Centro de Usos Multiples in Los Mochis, Sinaloa, Mexico, on September 6, 2025. He won by unanimous decision.

Núñez vs. Navarrete Núñez faced WBO junior-lightweight champion Emanuel Navarrete in a title unification bout at Desert Diamond Arena in Glendale, Arizona, USA, on February 28, 2026. He lost the fight by technical knockout at the start of the 11th round when the ringside doctor ruled an injury to his right eye was too bad for him to continue.
