In his second fight for the promotion, Mir faced Javy Ayala at Bellator 212 on December 14, 2018. Mir successfully won the first round by taking Ayala down and controlling him on the ground.

Frank Mir was a color commentator for World Extreme Cagefighting until WEC 47, when he was replaced by Stephan Bonnar. In June 2012, Mir stated in an interview with The Chronicle-Journal that he wants to pursue commentary after he retires from fighting. "I like analyzing fights, and I like doing color commentating," he said. "It's an opportunity I would take advantage of when I run into it. Hopefully it's something I can do full time". Mir is now the color commentator for Absolute Championship Berkut.

Mir faced former IFL Heavyweight Champion Roy Nelson on May 28, 2011, at UFC 130. He won via unanimous decision (30–27, 30–27, and 30–26) by using superior control and constant pressure.

A rematch with Antônio Rodrigo Nogueira took place on December 10, 2011, at UFC 140. In the bout, Mir was dropped during the first round by a punch from Nogueira, and the bout was nearly stopped. Mir quickly recovered and gained superior positioning, defeating Nogueira by kimura at 3:38 of round 1, snapping Nogueira's arm in the process, as Nogueira refused to tap. Along with being the first fighter to have finished Nogueira via knockout, Mir became the first fighter to have defeated Nogueira via submission in mixed martial arts. The victory also earned Mir Submission of the Night honors. UFC President Dana White called it the "submission of the century" at the post-fight press conference.

Mir faced Shane Carwin for the UFC Interim Heavyweight Championship on March 27, 2010, at UFC 111. After a brief standup exchange, Carwin pushed Mir against the cage, where he delivered several short uppercuts to Mir's chin. Mir lost the fight via knockout at 3:48 of the first round.

At a UFC Fan Expo, Mir said he briefly considered dropping down to the Light heavyweight division, although he later confirmed he would remain at Heavyweight. He was expected to face Antônio Rodrigo Nogueira on September 25, 2010, at UFC 119 in a rematch of the Interim Championship bout which Mir won via TKO at UFC 92. Nogueira pulled out of this fight due to knee surgery and was replaced by Mirko Cro Cop. Mir defeated Mirko Cro Cop via third-round knockout, earning the win with a knee from the clinch in a largely uneventful fight in which neither fighter was able to deliver any significant offense.

Two days after the fight, Dana White revealed in an interview that "Nogueira had just gotten over a Staph infection." Nogueira himself verified this fact several months later in his own interview, stating that he had a staph infection "20 days before the fight, [requiring] 5 days in the hospital." When asked if this infection affected his fight, he answered, "For sure." In addition to this illness, his knee was injured during training, for which he had surgery in February 2009. Despite these handicaps, Nogueira offered strong praise for Mir's performance, with particular credit given to Mir's ability to maintain "very good distance."

Mir's victory over Nogueira set in place a re-match with the UFC Heavyweight Champion Brock Lesnar for the UFC Heavyweight Championship. However, Mir stated, that in his opinion, holding victories over former UFC Interim Heavyweight Champion Antônio Rodrigo Nogueira at UFC 92 and current UFC Heavyweight Champion Brock Lesnar at UFC 81 is enough to recognize him as the owner of the "real belt." Mir was originally scheduled to fight Lesnar at UFC 98 On May 23, 2009, in Las Vegas, Nevada, however, he sustained a knee injury during training which required arthroscopic surgery and the removal of bone chips from his knee. The rematch against Lesnar was therefore rescheduled for UFC 100 on July 11, 2009. The show would break many UFC records in terms of PPV sales and is in the top 3 best selling UFC PPV of all time.

Mir had his next fight against Cheick Kongo on December 12, 2009, at UFC 107. Two months prior to this fight, Mir replaced his striking coach Ken Hahn with boxing trainer Jimmy Gifford. Mir was expected to weigh 20 to 25 lbs heavier than usual, due to the strength and conditioning program that he had undertaken to improve his muscular frame. As expected, Mir weighed in for his fight against Kongo at 264.5 lbs. At the weigh-ins, Kongo refused to face Mir during the traditional stare-down before the fight. During the fight, Mir stunned Kongo with an overhand left early, dropping him and swarming to secure a guillotine choke victory at 1:12 in the first round. Kongo refused to tap and was rendered unconscious by the choke. In the post-fight press conference, Mir expressed his desire to fight a rubber match with Brock Lesnar. Mir later created controversy after commenting that he wanted to break Lesnar's neck, so that he would become the first mixed martial artist to die in competition. Mir later made an apology for his comments after being admonished by Dana White.

On February 2, 2008, at UFC 81, Mir welcomed former WWE wrestler Brock Lesnar to the octagon for Lesnar's highly anticipated debut. It took Lesnar less than 10 seconds to shoot for a takedown and muscle Mir to the mat. However, seconds after Lesnar began to unload strikes from Mir's half guard, referee Steve Mazzagatti controversially deemed that there were some illegal punches landed to the back of Mir's head, drawing a foul and a one-point deduction. The fighters were ordered to stand up, and Mir was given a brief recovery period. As the fight resumed, Mir was almost instantly dropped with a big punch from Lesnar. Lesnar continued to land punches on Mir and shucked off Mir's armbar attempt before moving to a stacked guard. It was here that Mir caught Lesnar with a kneebar, causing Lesnar to tap out at 1:30 of the first round. Mir was awarded with Submission of the Night honors.

Spike TV announced on May 12, 2008, that former UFC champion Frank Mir would face off with the current UFC Interim Heavyweight Champion and former PRIDE Heavyweight Champion Antônio Rodrigo Nogueira as the coaches for the eighth season of The Ultimate Fighter.

Mir was scheduled to fight kickboxer Antoni Hardonk at UFC Fight Night 9 on April 5, 2007, but had to drop out due to a shoulder injury. He faced Hardonk at UFC 74 and won via kimura at 1:17 of the first round. At the end of the bout, Mir walked to the cameras pointing at himself saying "I'm back!". Frank's wife Jennifer was shown on the replay screaming and crying with joy when Frank secured the kimura and the fight was stopped.

In his first bout since the accident, Mir fought 4th degree BJJ black belt and six-time Mundials Champion Márcio Cruz at UFC 57: Liddell vs. Couture 3 on February 4, 2006. In a shocking upset, Mir was defeated by first round TKO. He returned to the octagon on July 8, 2006, at UFC 61: Bitter Rivals against Dan Christison. Mir won by unanimous decision when all three judges scored the bout 29–28. Mir was widely criticized following the bout due to his sloppy appearance and inability to finish a seemingly mismatched opponent. Despite the criticism, Mir was subsequently matched with Brandon Vera at UFC 65: Bad Intentions to determine the number one contender. Mir showed improved striking ability but was quickly stunned by a straight right from Vera, who then dropped him with knees from the Muay Thai clinch. Vera then secured side control and delivered a number of punches and elbows, forcing the referee to stop the fight at 1:09 of the first round. While preparing for UFC 140, Mir attributed his poor performance in his initial return bouts to lingering health issues following the accident.

On June 19, 2004, Mir faced Tim Sylvia for the vacant UFC Heavyweight Championship at UFC 48: Payback. Referee Herb Dean stopped the fight 50 seconds into the first round after Mir broke Sylvia's right forearm with a straight armbar. Sylvia initially protested the call but relented following a replay of the break. He was taken to a nearby hospital where an x-ray showed that his arm was broken in four places, two in both the radius and ulna bones of his right forearm. Sylvia underwent surgery later that week. Mir earned his BJJ black belt from Ricardo Pires following this performance.

On September 17, 2004, Mir was knocked off his motorcycle by a car. The accident caused two breaks in Mir's femur and tore all the ligaments in his knee. An Interim Heavyweight Championship was created while Mir recovered from surgery, which Andrei Arlovski won by defeating Tim Sylvia via first round submission. On August 12, 2005, the UFC learned that Mir would not be able to face Andrei Arlovski in October as scheduled and stripped him of the title after 14 months, promoting Arlovski to undisputed UFC Heavyweight Champion. In 2010, Mir told FIGHT! Magazine that he was grateful for the accident as it gave him time to be with his wife.

Mir then faced Tank Abbott at UFC 41 on February 28, 2003. Mir submitted Abbott with a toe hold in 46 seconds. On June 26, 2003, Mir fought Wes Sims at UFC 43: Meltdown. Mir won by disqualification at 2:55 of the first round after Sims stomped on Mir's jaw following a slam escape of an armbar attempt by Mir.

Mir faced Ian Freeman in London, England, at UFC 38: Brawl at the Hall on July 13, 2002. Despite several leglock attempts by Mir, Freeman achieved side control four minutes into the first round and landed numerous punches and elbows to Mir's head. A time out was called due to a cut on Mir's face. After Freeman separated, the referee signaled to Mir to stand back up and stopped the fight after Mir struggled to do so.

Mir met UFC matchmaker Joe Silva at a Brazilian jiu-jitsu (BJJ) school. Silva saw potential in Mir and suggested that he compete in mixed martial arts. Mir made his professional debut against Jerome Smith at HOOKnSHOOT: Showdown on July 14, 2001. Mir won the bout by unanimous decision after two rounds. He won his second fight by triangle choke in the first round, against Dan Quinn at IFC Warriors Challenge 15 on August 31, 2001.

On November 2, 2001, at UFC 34: High Voltage, Mir made his UFC debut against 6th degree BJJ black belt Roberto Traven. Traven had previously competed in the UFC (at UFC 11) and was the 1999 ADCC Submission Wrestling World Championship open class champion. Mir defeated Traven by armbar at 1:05 of round one, earning "Tapout of the Night" in the process. Mir's next UFC match was against Lion's Den fighter and eight-time UFC veteran Pete Williams at UFC 36: Worlds Collide on March 22, 2002. Mir submitted Williams in 46 seconds with an inside shoulder lock that has since been named after himself. It was the only submission loss of Williams' career.

Born and raised in Las Vegas, Nevada, Mir began training and competing in American Kenpo at a school owned by his parents, earning his black belt as a teenager. Mir's father was a Cuban-born wrestler of Moroccan and Russian heritage, who played a major role in convincing him to begin wrestling on the basis that it could help him avoid submissions. Mir joined the wrestling team at Bonanza High School during his junior year and lost his first nine matches. During his senior year (1998) he went 44–1 and won the state championship. Mir played fullback and defensive end on the school's American football team, which reached the Southern Zone semifinals in 1997. He also competed in track and field; his discus throw of 177 feet, 10 inches (54.20 meters) is still a Sunset Regional record.
