Matthew Stevens 9–13 in the second round. This was his first run to the last 16 of a tournament and helped him into the top 32 of the rankings (at no. 29).
In the
2007 Grand Prix, in a match with Ken Doherty, he was involved in an incident that led to his opponent branding him "a disgrace". Unhappy that the black would not go back on its spot after potting it, Allen struck the side cushion of the table with his fist. The referee told him that he would be warned if he did that again. Allen was not warned, and ended up winning the match. Doherty said, "He was a disgrace. For such a relative newcomer to the pro game, he's got a serious attitude problem". Allen later commented: "It was entirely my own fault and if there are going to be any repercussions then so be it." Allen did not reach the knockout stage of the tournament.
In the
2007 Northern Ireland Trophy he beat
Graeme Dott and
Ryan Day, 5–3 in each case, to reach his first ever quarter-final. There he defeated
Gerard Greene 5–3 to reach the semi-final, where he lost 3–6 to

Judd Trump with whom he held a 2–1 advantage in the previous meetings between the pair. Allen opened up a 3–1 lead early in the best of 19 frames match, but subsequently lost the next seven frames to trail 3–8. However, such a deficit brought out the best in Allen as he won five of the next six frames, which included three centuries. The comeback was not quite completed though, as Trump secured the frame he required to take an 8–10 victory. Allen said after the final, "I knew it was going to be hard the way he was playing, he scores so heavy and so quickly and I didn't feel I was playing too bad but Judd played so well and it was hard to compete." Allen made five centuries during the tournament, the most of anyone in the event.
Allen lost the last four frames in the first round of the
Masters to
Neil Robertson having led 3–2 and stated afterwards that he had "completely lost interest" in the match. He accused the Australian of employing slow tactics and said that at times he didn't want to watch him play. He then exited the

2020/2021 season
Allen's most notable achievement during the
2020/2021 season was winning the
2020 Champion of Champions. He defeated Ronnie O'Sullivan in a contentious quarter-final that saw O'Sullivan accusing Allen of deliberately standing in his line of sight and Allen accusing O'Sullivan of being a 'bully'. Allen went on to defeat
Judd Trump in the semi-finals and
Neil Robertson 10–6 in the final.
2021/2022 season
In the
2021/2022 season, Allen won his first
Northern Ireland Open title, coming from 6–8 behind in the final to defeat John Higgins 9–8. Earlier in the tournament, in his qualifying round match against
Si Jiahui, he made the second maximum break of his professional career. Allen was unable to make a deep run at any of the triple crown events during the season. At the
2021 UK Championship, he was defeated 56 by Gilbert in the last 32, and he lost in the first round of the
2022 Masters 56 to Trump. Allen exited the
2022 World Championship after a 413 loss to O'Sullivan in the last 16.
2022/2023 season
In October, Allen reached the final of the
British Open, but was defeated 710 by
Ryan Day. Later in the month, he successfully defended his crown at the
Northern Ireland Open. He won eight consecutive frames during his 94 win over Zhou Yuelong in the final, at his home tournament in Belfast. Allen remarked afterwards, "You know how proud a Northern Irishman I am and how much I want to do well here for the fans. To win two years in a row is something." At the
2022 UK Championship, Allen knocked out Jordan Brown, Kyren Wilson,
Sam Craigie and Jack Lisowski to reach the final where he won 10–7 against Ding, coming back from 1–6 behind. After his victory, Allen said "To beat Ding in the best of 19 frames match when being 6-1 down is one of my best-ever wins". Allen secured his third title of the season at the
World Grand Prix, after triumphing over Trump 109 in the final. At the
2023 World Championship, Allen defeated
Jak Jones 1310 in the quarter-final, but then, lost 1517 against Selby in the semi-final.
2023/2024 season

before losing his second round match to Higgins 1213.
2024/2025 season

Chris Wakelin. He became the eleventh player to do so at the Crucible, but despite this, it wasn't enough to prevent a 613 defeat and an exit from the tournament.
Rivalry
Allen has had a rivalry with
Stuart Bingham. After Bingham squandered a 12–9 lead in the second round of the
2011 World Snooker Championship to lose 13–12 against
Ding Junhui, Allen stated that Bingham had "no bottle" and admitted that there was history between the players and that they did not get on. Bingham responded by calling Allen an idiot and the tension between the two was clearly high as they were drawn to play each other in the second round of the
2011 Australian Goldfields Open. Before the match, Bingham said that he could not wait to play and that he had been waiting for it for a long time. He also stated that he did not care what Allen thought and it would give him more pleasure to beat him. Bingham fulfilled his pre-match words by defeating Allen 5–3 and also went on to win the tournament by coming back from 8–5 down to beat
Mark Williams 9–8 in the final.
When the draw for the
2011 UK Championship was made it revealed that there was a potential quarter-final clash between the two. Anticipating the meeting, Bingham said that the "feud was not over" and that he would be staying away from Allen and not be speaking to him until they next played. The match-up was avoided, however, when Bingham lost in the first round to
Marco Fu. Allen announced before the start of the
2013 World Championship that there was no problem between himself and Bingham since Bingham had proved him wrong by winning tournaments, and the two have had drinks and dinner together. After Bingham won the
2015 World Championship he said "Thanks to Mark Allen. He said I had no bottle and since then things have changed".
Allen also has a rivalry with
Mark Joyce and has made no secret of his dislike for him, stating that: "I don't like Mark Joyce, basically he is a dick, on and off the table, I doubt even his mum likes him." He went on to accuse Joyce of
gamesmanship during their match at the
2016 Northern Irish Open.
Controversies
After his first-round win at the
2011 UK Championship, Mark Allen called for
WPBSA chairman
Barry Hearn to resign, claiming Hearn had broken a promise not to change major tournament formats. Allen criticized the new best-of-11 format for the UK Championship, compared the atmosphere to darts, and said snooker tradition was "going to pot." He also swore during the press conference, leading to WPBSA disciplinary action for bringing the game into disrepute. Hearn dismissed Allen's remarks, calling them childish. After a meeting in January 2012, Hearn said they had a frank but friendly exchange, and noted Allen's increased prize money as a sign of progress. Allen was later fined £250.
In 2012, Allen was fined £1,000 by the WPBSA for criticizing conditions at the
World Open in

Mark Allen was fined £11,000 after accusing

of cheating following his defeat at the
2012 World Snooker Championship. He claimed Cao failed to admit a foul and attributed it to cultural differences, referencing past incidents with other Chinese and Hong Kong players. Barry Hearn said he was "speechless" and confirmed Allen would face disciplinary action.
In addition to the fine, Allen was warned he could face a three-month suspension if he breached the rules again within six months and was required to complete media training.
Prior to the commencement of the
2013 World Snooker Championship
The 2013 World Snooker Championship (officially the 2013 Betfair World Snooker Championship) was a professional snooker tournament that took place from 20 April to 6 May 2013 at the Crucible Theatre in Sheffield, England. It was the 37th consec ...
, Allen renewed his criticisms of Barry Hearn. Allen voiced concerns that the
World Snooker Tour's increasing emphasis on events in China was pricing players out of competing, pointing out that since Hearn took over the running of the game players now have to pay for their own flights, which can incur extra expenses of £10,000–£15,000 per season. Allen, who earned £278,000 over the course of the previous two years, further added he did not believe he was being fairly compensated for his services.
At the
2019 World Grand Prix, he conceded the match against
Ali Carter in the fifth frame with 11 reds on the table after missing the yellow.
Personal life

In 2005, Allen began a relationship with women's world snooker champion
Reanne Evans. They had a daughter, Lauren Sophie, born in May 2006, when both parents were 20 years old. Evans and Allen ended their relationship in 2008. Following his breakup with Evans, Allen fell into a deep depression and had periods where he did not leave his home. Allen and Evans have continued to be involved in legal disputes over child maintenance payments. In 2022, Allen noted that he no longer sees Lauren, but said "I still think about her all the time".
Allen met Kyla McGuigan in 2011 and the couple married on 10 May 2013.
Kyla McGuigan's son from a previous relationship,
Robbie McGuigan, became a noted amateur snooker player, winning under-16 and under-21 tournaments at an early age and achieving a 147 break in 2018 at age 13. Robbie McGuigan subsequently won the Northern Ireland Amateur Snooker Championship for three consecutive years from 2021–23. Allen and Kyla McGuigan had a daughter, Harleigh, born in 2017, but by May 2020 they had separated and were in the process of divorcing. In May 2021, Allen declared himself
