The 1991 World Snooker Championship (also referred to as the 1991 Embassy World Snooker Championship for the purposes of sponsorship) was a professional ranking snooker tournament that took place between 20 April and 6 May 1991 at the Crucible Theatre in Sheffield, England.

Stephen Hendry was the defending champion, but he lost in the quarter-finals to Steve James and thus fell to the Crucible curse, becoming another champion who was unable to defend his first world title.

John Parrott won his only World Championship title by defeating Jimmy White 18–11 in the final.

The highest break of the tournament was 140, made by Jimmy White.
