The championship cannot be competed for by anyone who is over the Cruiserweight division weight limit of 105kg (231lb).[1] Traditionally this division is labelled as the "Junior Heavyweight" division in Mexico while "Cruiserweight" is a term more used in the United States or Canada.
The championship was originally named the AAA Cruiserweight Championship. but had the word "world" added to the name after El Hijo del Fantasma won a match on August 17, 2014, that unified the championship with the AAA Fusión Championship. A total of fourteen men have held the championship for a total of sixteen different title reigns.

On August 17, 2014, at Triplemanía XXII, the Cruiserweight Champion Daga defended the title in a 10-man elimination match, where also participated the AAA Fusion Champion Fénix.

On February 10, 2021, the champion Laredo Kid faced the Major League Wrestling's World Middleweight Champion Lio Rush in a title vs. title match. Despite Rush winning the match and being recognized as champion, a few days later AAA did not recognize the title change. Instead, Laredo Kid appeared on AAA show with the title belt. According to Konnan, an AAA booker, Rush lost the title back to Laredo Kid in a un-televised match.
