List of UFC champions

Ultimate Fighting Championship (UFC) champions are fighters who have won UFC championships.

Historical notes
At the time of the UFC's inception in 1993, mixed martial arts was not sanctioned in the United States, and did not include weight classes. Instead of the traditional championship model, the UFC held tournaments with the winner receiving a permanent appellation. In response to criticism from Senator John McCain that saw the loss of its television deal and the banning of the sport in thirty-six states, the UFC increased its cooperation with state athletic commissions and introduced weight classes in 1997, starting with UFC 12, and began introducing weight-specific titles.

The original codification for weight classes introduced only two divisions: heavyweight, which grouped together all competitors above 200 lb, and lightweight, which encompassed all competitors 199 pounds (90 kg) and under. At UFC 14 the lightweight division would be renamed to middleweight, though it would still encompass all fighters 199 pounds (90 kg) and under. The lightweight moniker would later return at UFC 16 with a new division consisting of those competitors 170 lb and under. Two years later a fourth weight class, the bantamweight division, arrived at UFC 26 and included all fighters 155 lb and under.

In 2000, the New Jersey State Athletic Control Board completely took over MMA regulation in its home state and developed new rules and weight classes that eventually became the de facto rule set for all mixed martial arts. The UFC realigned their weight classes to comply with these new regulations in 2001, beginning with UFC 31. At the time, this brought the total number of active divisions in the UFC to five: lightweight, welterweight, middleweight, light heavyweight, and heavyweight.

It would be nearly ten years before the UFC would expand their divisional offerings to include any of the lower weight classes. The first additions came in late 2010 when the UFC merged with their sister organization World Extreme Cagefighting (WEC). Due to the WEC's focus on lighter weight fighters, this merger necessitated the addition of both the featherweight and bantamweight divisions to the UFC, starting with The Ultimate Fighter season 12 finale. In early 2012 the UFC decided they would delve even further into the lower weight classes when they announced the introduction of the flyweight division to their ranks, beginning with UFC on FX: Alves vs. Kampmann.

In November 2012, as a result of the forthcoming dissolution of their sister organization Strikeforce, the UFC announced they would be adding female fighters to their roster for the first time in the promotion's history. Initially, only the women's bantamweight division was brought over, with the division's premiere bout taking place at UFC 157. A little over a year later, the UFC announced they would be expanding their weight classes for female fighters with the addition of a women's strawweight division, the first bout took place at UFC Fight Night: Cowboy vs. Miller. In late 2016, a featherweight division was introduced for the women with the first bout to be for the inaugural championship at UFC 208 on February 11, 2017. In that same year the UFC announced the Women's Flyweight division would officially be added, with the winner of the 26th season of The Ultimate Fighter to be named the inaugural champion.

The Ultimate Fighter
The Ultimate Fighter (TUF) is a reality television series and mixed martial arts competition produced by the UFC. The show features professional fighters living together and competing against one another in a tournament for a contract with the UFC.

Championship wins by nationality
The table is divided by number of division championships, tournament championships, total championships, and individual champions. Fighters with multiple championship wins have each championship counted for the total. There is a distinction between the total number of championships won by a nationality and the number of individual fighters that won them. Division championships are the primary separation criteria due to being non-closed competition. It includes title holders and interim title holders. Interim champions who become undisputed champions are listed only once. Tournament championships are secondary due to many tournaments being country-specific and thus not generally a national achievement to win. Runners-up and TUF runners-up are not included.

Most wins in title bouts
Fighters with four or more championship and/or interim championship title wins. Fighters with the same number of title wins are arranged in order of most title fights. Tournament championships and TUF winners are not included.

Most consecutive title defenses
The following includes all UFC champions who were able to consecutively defend their title three times or more. Fighters with the same number of title defenses are listed chronologically.

Missed weight title fights
There have been multiple instances in UFC history where a fighter misses the required weight limit for a championship fight.
