Longest title reign: since 2020

Longest single reigns as undisputed UFC champion, in days.

All timeSince 2020Since 2010Since 2001Before 2000
Reset

Reigns are derived from championship bouts. When a belt was vacated or stripped outside a title fight, the reign is shown ending at the next title fight in that division, so a few run long; a title awarded without a fight (José Aldo's in 2010, for one) starts at the champion's first UFC title fight.

50 reigns.
