The 2001 Irish Masters (officially the 2001 Citywest Irish Masters) was a professional invitational snooker tournament which was held at the Citywest Hotel in Saggart, Dublin, from 27 March to 1 April. It was the 24th Irish Masters and the fifth and final World Professional Billiards and Snooker Association invitational event in the 2000–01 snooker season. The tournament was co-sponsored by the Health Promotion Unit and the Office of Tobacco Control of the Department of Health and Children and hotel group Citywest.
John Higgins was the defending champion of the tournament but was eliminated in the quarter-finals following a defeat by Peter Ebdon. Ronnie O'Sullivan, three-time tournament winner over the course of the season, won the competition, beating three-time Irish Masters winner Stephen Hendry nine frames to eight (9–8) in the final. In the semi-finals, O'Sullivan defeated Ebdon and Hendry beat defending world champion Mark Williams. O'Sullivan made a century break of 137 in the second frame of his quarter-final match with six-time world champion Steve Davis, the highest of the tournament.
