IWRG Intercontinental Heavyweight Championship
The IWRG Intercontinental Heavyweight Championship is a singles Championship in the Mexican lucha libre promotion International Wrestling Revolution Group and was introduced in 1997. It has since been defended throughout Mexico, primarily in Naucalpan, but also in Japan as well. As the Championship is designated as a heavyweight title, it can only officially be competed for by wrestlers weighing at least.
The current champion is DMT Azul, who defeated previous champion Dr. Wagner Jr., Chessman and Pirata Morgan for the championship on October 31, 2025. The first holder of the IWRG Intercontinental Heavyweight Championship was Pierroth Jr. who won the title on September 28, 1997 defeating Black Magic in the finals of an eight-man tournament. There have been twenty-five recognized champions, combining for thirty-four total reigns. Máscara Año 2000 Jr. and Scorpio Jr. are tied for most championship reigns, with four each. El Canek holds the record for the longest individual reign 1,444 days. Valletta's first reign lasted 11 days, the shortest of any champion.
As it is a professional wrestling championship, the championship was not won not by actual competition, but by a scripted ending to a match determined by the bookers and match makers. On occasion the promotion declares a championship vacant, which means there is no champion at that point in time. This can either be due to a storyline, or real life issues such as a champion suffering an injury being unable to defend the championship, or leaving the company.
