The 2001 World Snooker Championship was a professional ranking snooker tournament that took place between 21 April and 7 May 2001 at the Crucible Theatre in Sheffield, England.

Mark Williams was the defending champion, but he lost in the second round 12–13 against Joe Swail and became another first-time champion who fell to the Crucible curse and could not defend his first World title.

Ronnie O’Sullivan won his first World title by defeating John Higgins 18–14 in the final.
