List of The Ring world champions

None

None

Boxing magazine The Ring has awarded world championships in professional boxing within each weight class from its foundation in 1922. The first Ring world title belt was awarded to heavyweight champion Jack Dempsey, and the second was awarded to flyweight champion Pancho Villa. The magazine stopped giving belts to world champions in the 1990s, but reintroduced their titles in 2001.

Boxers who won the title but were immediately stripped and the title bout being overturned to a no contest will not be listed.

While there was no official featherweight champion between 1989 and 2002 (as The Ring awarded no titles in any division during that period), Naseem Hamed was retroactively awarded the Ring title in 2019 (the only former world champion in any division thus far to receive this honor) due to his dominance of the division and the multiple champions he beat.

Junior bantamweight

No.NameReignDefenses1Naoya Inoue was the Ring No. 1-rated junior bantamweight, but for this fight the Ring title was put on the line because the magazine's panel considered Inoue may move up to bantamweight. Ultimately, Inoue neither moved up or vacated his WBO junior bantamweight title, therefore the Ring title was essentially fought between the No. 2- and No. 3-rated boxers.23
