2021 Northern Ireland Open

The 2021 Northern Ireland Open (officially the 2021 BetVictor Northern Ireland Open) was a professional ranking snooker tournament that took place from 9 to 17 October 2021 at the Waterfront Hall in Belfast, Northern Ireland. It was the third ranking event of the 2021–22 season and the first tournament in both the Home Nations Series and the European Series. It was the sixth edition of the Northern Ireland Open.

Qualifying for the tournament took place from 23 to 27 August 2021 at the Morningside Arena in Leicester, England, although matches involving the top 16 players, and three other matches featuring Northern Irish players, were held over and played at the Waterfront Hall. All of the top 16 players participated except for world number 9 Ding Junhui. Mark Allen made a maximum break in his held over qualifying match against Si Jiahui.

The defending champion was Judd Trump, who defeated Ronnie O'Sullivan in the 2018, 2019 and 2020 finals by a scoreline of 9–7 each time. Trump lost 3–5 in the quarter-finals to Allen, having led 3–0.

Allen faced John Higgins in the final, which was tied at 4–4 after the afternoon session. Higgins moved 8–6 ahead in the evening session, but Allen won the last three frames for a 9–8 victory. It was Allen's first Northern Ireland Open title, his second Home Nations win, and the sixth ranking title of his professional career.

Qualifying
Qualification for the tournament took place from 23 to 27 August 2021 at the Morningside Arena in Leicester, England. Matches involving the top 16 players — including the defending champion — alongside three other matches involving local players, were held over and played at the Waterfront Hall. Graeme Dott, Anthony Hamilton, Mark Davis and Robbie McGuigan were due to take part in the event, but withdrew and were replaced by James Cahill, Dylan Emery, Mark Lloyd and Robert McCullough respectively.

An incident took place in the players lounge after the Peter Lines v Xiao Guodong match. Lines confronted Xiao in the players' lounge after the match, accused him of cheating. Lines also swore at Xiao, and challenged him to a fight, leading to security personnel removing Lines from the lounge. The incident was in relation to perceived inaccuracies in ball placement by the referee after a foul and a miss was called during a frame of their match. The incident was reported to the WPBSA and Lines was found guilty at a subsequent hearing after the tournament of; breaching the code of conduct for members of the WPBSA, bringing the WPBSA into disrepute, bringing the game of snooker into disrepute, and for engaging in conduct likely to cause an opponent to be unduly influenced so as to affect the outcome of a match or event. Lines was ordered to pay a fine and costs. Lines subsequently apologised for his conduct to Xiao.
