The CMLL World Heavyweight Championship is a men's professional wrestling world heavyweight championship created and promoted by the Mexican promotion Consejo Mundial de Lucha Libre (CMLL). It was introduced in 1991 to signal CMLL's independence from the National Wrestling Alliance (NWA), as CMLL had left the NWA in the late 1980s but had continued to promote the NWA's championships. As part of the move away from the NWA, CMLL established championships designated as "CMLL World Championships" for several weight divisions. The Heavyweight Championship was the first CMLL title to be created, and the inaugural champion was Konnan el Bárbaro, who won the title on June 9, 1991. The current champion is Hechicero, who is in his second reign. He defeated Claudio Castagnoli on March 20, 2026. Nineteen different wrestlers have held the championship, split over 24 separate championship reigns.
