An octuple champion is a boxer who has won major world titles in eight weight classes. To date, the only octuple champion is Manny Pacquiao, who has won twelve major world titles.[1]
Pacquiao achieved the feat when he defeated Antonio Margarito via a unanimous decision to win the WBC super welterweight title on November 13, 2010 at the Cowboys Stadium, Arlington, Texas, US.[2]
Nine of his world championships came from the "Big Four" sanctioning bodies (WBA, WBC, IBF, WBO) and three were from The Ring.
He also won the prestigious and coveted lineal championship in five weight divisions: flyweight, featherweight, super featherweight, light welterweight, and welterweight.[3]
The following are the major world titles won by Pacquiao (arranged chronologically). Titles are listed only once per organization per weight class:
