World Association of Kickboxing Organizations
World K-1 Rules Welterweight Title [66.8kg] (as of 2026-05-02)
* "Thai Boxing" title until 2007.
As it is difficult to find comprehensive kickboxing results from the 20th century, these lists are always "under construction." Also this title is controlled by one of those organizations that have world titles in multiple categories such as kickboxing, K-1 rules, full contact, etc. Because many match results do not specify the category, some of these entries may be for another category. If you have corrections or additional information, please send in!
* Bolded letters in the competitor's name, if any, indicate the surname/family name.
