Most title defences in UFC history

What counts. A defence is a win in an undisputed divisional title bout by the fighter who won the previous undisputed title bout in that division. The lineage is walked off the record itself in date order — the first title bout in a division crowns a champion, which is a title win and not a defence; after that, a win by the sitting champion is a defence and a win by anybody else installs a new one. Interim titles, the 1990s tournament titles and the 1995–96 Superfight Championship are named as such on the official record and are not in any lineage here. A draw or a no-contest in a title bout changes nothing, which is also the real rule: the champion retains. A belt vacated between title bouts is invisible to a record made of fights — the next title bout simply reads as a new champion — so no defence is invented for it and none is lost. One name on the record is shared by two different fighters our source roster cannot tell apart, so any career total under it would be two people’s added together. It is left out of every page in this family entirely — the same reason that fighter’s own page is withheld — rather than published as a total that is nobody’s. A bout carries a weight class; a career does not. On a division page each fighter is filed under the division they were in for most of the bouts THIS record counts — where the wins were actually won, not where they finished up — with a tie going to their most recent bout. Fighters whose counted bouts carry no weight class on the record (catchweight, open weight, the 1990s tournaments) appear only on the all-divisions page. Ties. 17 of the rows below share the same 1 title defence. Where two fighters share a total they are listed by the earlier start to their record and then alphabetically — they did not reach the same number in any order, so a tie-break claiming precedence would be an assertion the record does not contain. Check us. Every total here is counted from the official UFC statistical record on each build; nothing on this page is typed in by hand. Each name links that fighter’s own page, where every fight the total is made of has its own row and its own bout page — so a number can be checked one fight at a time.
