List of CMLL World Light Heavyweight Champions

The CMLL World Light Heavyweight Championship (Campeonato Mundial Semi Completo de CMLL in Spanish) is a singles professional wrestling world championship promoted by Consejo Mundial de Lucha Libre (CMLL) since 1991. As it is a professional wrestling championship, it is not won legitimately: it is instead won via a scripted ending to a match or awarded to a wrestler because of a storyline. The official definition of the Light Heavyweight weight class in Mexico is between 92 kg (203 lb) and 97 kg (214 lb), but is not always strictly enforced.^{[Note 1][1]} Because Lucha Libre emphasizes the lower weight classes, this division is considered more important than the normally more prestigious heavyweight division of a promotion.^[2] All title matches take place under two out of three falls rules.

The current champion is Averno, who won the championship by defeating Bárbaro Cavernario at Homenaje a Dos Leyendas on March 29, 2024.

The first champion to be recognized by CMLL was Jerry Estrada, who defeated Pierroth Jr. in the finals of a 16-man tournament that took place between September 15 and September 26, 1991. Overall, there have been sixteen reigns shared among fourteen wrestlers. Dr. Wagner Jr. and Atlantis are the only two wrestlers to have held the title twice; Dr. Wagner Jr. is listed as an unofficial three-time champion, but he is not recognized as such by CMLL.^{[Note 2]} Jerry Estrada's 175 day reign is the shortest in history, while Niebla Roja holds the record for his first reign, at 2,516 days. Aquarius' unofficial title reign is the shortest on record, 8 days, but is not acknowledged by CMLL.
