Robert John Whittaker (born 20 December 1990) is an Australian professional mixed martial artist. He currently competes in the light heavyweight division of the Ultimate Fighting Championship (UFC), where he is a former UFC Middleweight Champion and the first Australian to win a UFC championship. As of 19 September 2026, he is in the Meta UFC light heavyweight rankings.

A professional since 2009, Whittaker was a contestant on the first series of The Ultimate Fighter: The Smashes and won the welterweight tournament. Whittaker became interim middleweight champion after winning the title at UFC 213; he was promoted to undisputed champion after Georges St-Pierre vacated the UFC Middleweight Championship in 2017.

Background

Whittaker was born at Middlemore Hospital in Ōtāhuhu, Auckland, New Zealand. His father is an Australian of European descent and his mother is of Samoan and Māori ancestry. Moving to Australia shortly after, Whittaker's father enrolled Robert, aged seven, and his brother in a Goju-ryu karate school, to encourage them in self-discipline and self-defence. After training in the discipline for around eight years, and earning his black belt, his father offered him the chance to change to another sport or drop karate entirely. While his brother decided to drop out, Robert chose to switch to a hapkido gym run by Henry Perez, following his move to Menai. Not long afterwards, Perez transformed his gym into an MMA gym. Having no other choice, Whittaker began training in MMA and was immediately hooked, choosing MMA as his preferred sport over rugby league. Whittaker was a talented rugby league player in his younger years and was placed in the development academy of the professional Cronulla Sharks club as a youth.

Whittaker prefers not to engage in trash-talk outside of the octagon:

I'm the type of fighter that goes into every fight with no ill will towards my opponent. I'm an athlete first and foremost and I love the sport.

Early career

In 2008, Whittaker signed with Australia's Xtreme Fighting Championships and made his debut 14 March 2009 against fellow pro debutant Chris Tallowin. Whittaker won the fight via TKO in the first round. Whittaker continued his career with Cage Fighting Championships, going 6–0 inside the promotion from 2009 to 2011, with a notable win over fellow TUF: Smashes cast member, Ben Alloway.

On 30 October 2011, Whittaker lost his first fight when he travelled to Cotai, Macau for Legend Fighting Championships 6: he fought Hoon Kim and lost via submission in the first round. Whittaker bounced back from the loss and won two consecutive bouts before suffering his second loss to Jesse Juarez, which brought his overall record to 9–2.

The Ultimate Fighter

In 2012, Whittaker's coach, Henry Perez, put him forward for the first series of The Ultimate Fighter: The Smashes, which pitted a team of eight Australians against a team of eight men from the United Kingdom, and he was selected as one of the cast members.

In his first fight on the show, Whittaker fought Luke Newman. Whittaker landed a punch flush on the chin of Newman after 19 seconds, knocking him unconscious for several minutes. The win moved him onto the semi-final round. The knockout also earned Whittaker an additional $25,000 for "Knockout of the Season".

In the semi-final, Whittaker was matched against replacement fighter and fellow Team Australia teammate, Xavier Lucas. Whittaker won via knockout at 1:17 in the first round. The win moved Whittaker into the final round of the competition, which would take place live on UFC on FX: Sotiropoulos vs. Pearson.

UFC Middleweight Champion

Whittaker fought for the interim middleweight title against Yoel Romero on 8 July 2017 at UFC 213, after Michael Bisping announced a nagging knee injury which would go on to keep him on the sidelines for several months. Whittaker won by unanimous decision, and became the first Australian and first New Zealand born fighter to hold a UFC title. This win earned him the Fight of the Night bonus award. He missed the remainder of 2017, as he was recovering from a medial knee injury to his left leg.

On 7 December 2017, then middleweight champion Georges St-Pierre vacated the title after being diagnosed with colitis. As a result, Whittaker was promoted to undisputed champion. He was slated for his first title defence at UFC 221 against former middleweight champion Luke Rockhold on 10 February 2018 at Perth Arena in Australia. On 13 January 2018, it was reported that Whittaker had pulled out of the event due to an undisclosed injury and would be replaced by Yoel Romero for the interim middleweight championship. The winner of this bout would then face Whittaker in a unification bout. On 20 January 2018, Dana White confirmed that Whittaker was in a serious condition after he was not properly treated from a staph infection in his stomach.

A rematch with Romero took place on 9 June 2018 at UFC 225. At the weigh-ins, Romero missed weight, coming in at 186 lbs, 1 pound over the middleweight limit for a title fight. Romero was given additional time to make weight, but he weighed in at 185.2 lbs, 0.2 lbs over the title fight limit. Romero was fined 20% of his fight purse and the fight was contested as a non-title catchweight bout. Whittaker won the fight by a close split decision. Their fight was awarded with 'Fight of The Night' honours. As Romero had failed to make weight, Whittaker received a $100,000 bonus, which would normally have been shared by both fighters.
