2017 Northern Ireland Open
snooker tournament

The 2017 Northern Ireland Open (officially the 2017 Dafabet Northern Ireland Open) was a professional ranking snooker tournament that took place between 20 and 26 November 2017 in the Waterfront Hall in Belfast, Northern Ireland. It was the tenth ranking event of the 2017/2018 season and a part of the Home Nations Series. It was the second edition of the Northern Ireland Open.
Mark King was the defending champion, but he was beaten 1–4 in the third round by Yan Bingtao. Yan went on to reach the final, becoming the youngest ever finalist of a ranking event. He faced Mark Williams, who won the 19th ranking title of his career by beating Yan 9–8. With his victory, Williams ended a ranking title drought dating back to the 2011 German Masters lasting 6 years and 9 months. Williams had come from 7–8 behind to win, and denied Yan becoming the youngest ever winner of a ranking event. Ronnie O'Sullivan still holds that record for the 1993 UK Championship.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
