World Vale Tudo Championship

Kerr made his debut in MMA at WVC 3 against UFC veteran Paul Varelans. The bout lasted two minutes, with Kerr slamming Varelans with a takedown, mounting him and landing punches and knee strikes for the stoppage. The same happened to his next opponent, Mestre Hulk, a

Kerr then reached the finals, where he was pitted against jiu-jitsu fighter Fabio Gurgel. Again, the fight would bring echoes, this time those of the bout between Erikson and Gurgel's teammate Murilo Bustamante, which happened the same year. Kerr went to the fight with a broken hand from the Hulk fight, but he had 50 pounds over Gurgel. He took Gurgel down, passed his guard with ease and bloodied him with multiple kinds of strikes. The situation prolonged itself by 19 minutes, with the Brazilian trying armlocks and triangle chokes from the bottom, but Kerr avoided them and kept landing punishment. The fight had no time limit, but at the 30 minute mark, seeing that Gurgel was unable to defend anymore, the judges stopped the fight and gave Kerr the win.

Following his success in Brazil, Mark Kerr was invited to fight in the

. Kerr had previously been told of the event by Coleman, who was himself a UFC tournament winner and champion by this point. Kerr's first bout in the UFC came at UFC 14 where he fought in the heavyweight tournament. His first fight was against krav maga representative Moti Horenstein, and Kerr defeated his opponent by technical knockout at 2:22 of the first round. With this win Kerr advanced to the finals of the tournament where he beat Dan Bobish with a submission (chin to the eye) at 1:38 of the first round; Kerr's win over Bobish earned him the UFC 14 Heavyweight tournament title. Following his success at UFC 14, Kerr was invited to compete at the next UFC tournament — UFC 15. In this tournament, Kerr's first opponent was Greg Stott whom he defeated in 17 seconds from the opening of the fight, winning by way of knockout with a knee to his opponent's head. Advancing to the finals, Kerr fought Dwayne Cason and finished his opponent within the first minute of the opening round, winning the UFC 15 Heavyweight tournament. Kerr's winning of the UFC 15 tournament was his last fight for the Ultimate Fighting Championship.'' The Smashing Machine: The Life and Times of Extreme Fighter Mark Kerr'' Following his win of UFC 15, Kerr decided to fight in Japan for the Pride Fighting Championships due to the UFC's promotional difficulties and Pride's larger paychecks.

Pride Fighting Championships

After considering an offer from Japanese promotion Shooto, Kerr signed up with Pride for a matchup against fellow UFC champion

at Pride 2 in 1998. The match, as per Gracie's demands, would have been without time limits or referee stoppages. However, Royce pulled out after the fight had been advertised. Kerr was then slated to fight Branco Cikatic. Kerr utilized the same ground-and-pound fighting style from his previous fights, taking his opponent onto the mat and then using strikes and submissions to try to finish the fight. Kerr was said to be an improved version of

because he was proficient in wrestling, submissions, and take downs, with good cardio and an ever-improving striking game under his tutelage with Bas Rutten. Around the time that Kerr entered PRIDE, some considered Kerr to be one of the top MMA Heavyweight fighters in the world. Kerr won four bouts between Pride 2 and Pride 6. However, his status was soon questioned after his first bout with Igor Vovchanchyn at Pride 7, in which he was knocked out by illegal knee strikes. Even though the loss was overturned and changed to a "No Contest" ruling, Kerr admitted that the initial loss had been a difficult decision for him to face. Following his fight against Vovchanchyn, Kerr fought in the Pride Grand Prix 2000 Opening Round and won over Enson Inoue. His win against Inoue earned him a place at the Pride Grand Prix 2000 Finals, where he fought

and lost by decision. Kerr underwent stitching for a split chin immediately after the fight due to the hard knees to the face. At Pride 10 - Return of the Warriors Kerr defeated Igor Borisov by submission. Four months later, at Pride 12 - Cold Fury, he lost by decision in the rematch with Vovchanchyn. Kerr then lost to Heath Herring at Pride 15 via TKO. With his second loss in a row, Kerr decided to take time away from MMA. In 2004, Kerr returned to PRIDE, fighting Yoshihisa Yamamoto at Pride 27. Just 40 seconds into the fight, Kerr attempted a double leg takedown, but accidentally spiked his head into the canvas, stunning him with Yamamoto quickly following up with punches to end the fight. With his third straight loss under the PRIDE FC banner, Kerr quit PRIDE. Speaking of Kerr's time fighting in Japan, Mark Coleman said, "Every time a fight came around he was pretty scared. He was intimidated by the whole situation and that is probably what led to him using pain killers."

Later career

After his loss to Yoshihisa Yamamoto, Kerr was supposed to make his comeback against Wes Sims in the American Championship Fighting (ACF) on May 6, 2006, at the Denver Coliseum, but was not medically cleared to fight due to a hand injury. On February 11, 2007, Kerr fought Mustafa Al Turk at Cage Rage 20: 'Born 2 Fight'. Kerr lost his footing after an attempted roundhouse kick and he was mounted, stunned with a series of blows and submitted within the first round. Kerr was supposed to fight

On July 26, Ralph Kelly stopped Kerr in the first round at Xp3. On September 27, 2008, Kerr lost to fellow heavyweight Jeff Monson by rear-naked choke, in a battle of former ADCC champions. On August 28, 2009, Kerr faced fellow wrestler Muhammed Lawal at an M-1 Global event. Kerr was taken down and subsequently pounded into unconsciousness in just 25 seconds, receiving several blows to the head after he was clearly unable to defend himself. This led the event's TV commentators to openly speculate that Kerr's fighting career was over. Guy Mezger, in the post-fight discussion, suggested that it was time for Kerr to "find another vocation". Kerr only won four of his 15 fights since 2000 and lost his last five fights.

During UFC 316's broadcast in June 2025, Kerr was announced as the next "pioneer wing" UFC Hall of Fame inductee during International Fight Week festivities in Las Vegas this June.

Rutten states during the documentary that due to Kerr's ability to end fights quickly, the Pride tournament directors were removing all of Kerr's 'weapons' (notably head-butts and knees to the head of a grounded opponent) in an attempt to make the fights last longer for television and crowd satisfaction.
