The 2018 World Snooker Championship (officially the 2018 Betfred World Snooker Championship) was a professional snooker tournament held from 21 April to 7 May 2018 at the Crucible Theatre in Sheffield, England. Hosted by the World Professional Billiards and Snooker Association, it was the 20th and final ranking event of the 2017–18 snooker season and the 42nd consecutive time the World Snooker Championship had been held at the venue. The tournament was broadcast by BBC Sport and Eurosport in Europe, and sponsored by betting company Betfred.
Welsh left-hander Mark Williams won his third world championship and 21st ranking title, defeating Scottish professional John Higgins 18–16 in the final. Williams' victory came 15 years after his second world title in 2003; before the start of the season, he had not won a ranking event in the previous six years. In winning the event, Williams received the highest prize money awarded for a snooker event, £425,000 of a total pool of £1,968,000. Aged 43, he was the third oldest winner at the crucible after Ronnie O'Sullivan who was 44 when he won the 2020 World Snooker Championship and Ray Reardon who was 45 when he won the title in 1978. Defending and three-time world champion Mark Selby had won the world title for the previous two years, but lost in the first round 4–10 to Joe Perry.
The highest break of the championship was scored by Higgins, who made a break of 146 in frame 13 of his second round win over Jack Lisowski. However, in qualifying for the event, Liang Wenbo scored a maximum break of 147.
