2025 Northern Ireland Open

The 2025 Northern Ireland Open (officially the 2025 BetVictor Northern Ireland Open) was a professional snooker tournament that took place from 19 to 26 October 2025 at the Waterfront Hall in Belfast, Northern Ireland. Qualifiers took place from 4 to 7 September at the Leicester Arena in Leicester, England. The 10th consecutive edition of the tournament since it was first staged in 2016, it was the seventh ranking event of the 2025–26 snooker season, following the 2025 Xi'an Grand Prix and preceding the 2025 International Championship. It was the second of four tournaments in the season's Home Nations Series, following the 2025 English Open and preceding the 2025 Scottish Open and the 2026 Welsh Open. The tournament was broadcast by TNT Sports in the United Kingdom and Ireland, by Eurosport in mainland Europe, by local channels in China and elsewhere in Asia, and by WST Play in all other territories. The winner received £100,000 from a total prize fund of £550,400.

Kyren Wilson was the defending champion, having defeated Judd Trump 9–3 in the 2024 final, but he lost 3–5 to Jack Lisowski in the quarter-finals. The final was contested between Lisowski and Trump, who reached the 50th ranking final of his career; it took place before 1,435 spectators, a record audience at a UK snooker event outside of the Masters. Lisowski defeated Trump 9–8 to win the first ranking title of his 15-year professional career, having previously lost six ranking finals. He dedicated the title to his parents, following the death of his father in March. The event produced 64 century breaks, 26 during the qualifiers in Leicester and 38 during the main stage in Belfast. Liam Pullen made the highest break of the tournament, a 143, while playing Long Zehuang in the second qualifying round.
