MMA is an individual sport. For a number of fighters, however, it’s been a definite family affair.

Over the course of MMA history, many families have produced multiple professional fighters. In rarer cases, a single family has given us multiple world-class pros—even multiple world champions.

Without further ado, here is B/R’s definitive list of the five best fighting families in MMA history.

Honorable mentions: The Emelianenko family, the Pettis family, the Couture family, the Overeem family, the Rua family, the Miller family, the Lauzon family, the Assuncao family.

The Lee Family

The Lee family has produced not one, not two, but three professional fighters—all three of whom have spent their entire careers competing for ONE Championship.
