The International Boxing Organization, typically referred to by its call letters IBO, is a boxing sanctioning body which awards world championship belts in all weight classes. It was founded in 1993.
The IBO is considered by most boxing fans and experts to be a "fringe" sanctioning body, and its champions are not widely recognized in most instances. However, it has gained some credibility in the past few years, thanks to its use of an independent computer ranking system to determine top contenders and the fact that such star fighters as Lennox Lewis and Roy Jones Jr have accepted and fought for IBO titles.
