UWA World Junior Heavyweight Championship

The UWA World Junior Heavyweight Championship (UWA世界ジュニアヘビー級王座) is a title that was originally promoted by the Mexican lucha libre promotion Universal Wrestling Association. After the UWA closed in 1995 the title was defended on the Mexican independent circuit and in the Puerto Rican promotion World Wrestling Council. In 2014, the title was revived by Japanese promotion Tenryu Project. In 2016, the title moved to the Pro Wrestling Freedoms promotion. The weight range for this championship was 97 kg to 107 kg.

As it is a professional wrestling championship, the championship is 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.

There have been a total of 47 reigns and five vacancies shared between 31 different champions. The title is currently held by The Wolf.
