Picking the greatest boxers of all time, from different countries around the world, was really an easy and fun task. Over the years I have researched this topic at great length and interviewed many people. I have spoken to the older generations of fans and fighters who personally saw many of the boxers fight that were before my time. Their expertise and the input they offered was invaluable.

For each fighter my main basis for ranking them was the height, peak, prime, and pinnacle of their careers regardless of weight or eras in which they fought. The level of their competition played a huge factor, but not necessarily their ring record.

Alphabetically by geographic area /country, here are my picks, with the runners up included:
