The 1991 World Seniors Championship was a professional snooker tournament that took place from 18 to 22 September 1991 at Trentham Gardens in Stoke-on-Trent, England. It was the first staging of the World Seniors Championship and was contested by sixteen players aged 40 or more, including several former World Snooker Champions. The event was promoted by Barry Hearn and sanctioned by the World Professional Billiards and Snooker Association.
Cliff Wilson won his first professional title, aged 57, by defeating Eddie Charlton by 5 frames to 4 in the final, after trailing 2–4. Doug Mountjoy made the highest break of the tournament, 110, against Mike Massey in the first round. The final was followed by an unofficial World Trickshot Championship won by Terry Griffiths. The World Seniors Championship was not held again until 2010.
