The 1980 World Snooker Championship, officially known as the 1980 Embassy World Snooker Championship for sponsorship reasons, was a ranking professional snooker tournament that took place from 22 April to 5 May 1980 at the Crucible Theatre in Sheffield, England. The tournament was the 1980 edition of the World Snooker Championship and was the fourth consecutive world championship to take place at the Crucible Theatre since 1977. It was sanctioned by the World Professional Billiards and Snooker Association. The total prize fund for the tournament was £60,000, of which £15,000 went to the winner.

There were 53 entrants to the competition, although four later withdrew. Qualifying rounds for the tournament took place at Romiley Forum, Stockport, from 5 to 18 April 1980; at the Redwood Lodge Country Club, Bristol, from 11 to 16 April; and at Sheffield Snooker Centre from 12 to 17 April. The main stage of the tournament featured 24 players: the top 16 players from the snooker world rankings and another eight players from the qualifying rounds. Ray Edmonds, Jim Meadowcroft, Tony Meo, Cliff Wilson and Jim Wych made their Crucible debuts. The defending champion and top seed in the tournament was Terry Griffiths, who had defeated Dennis Taylor 24–16 in the 1979 final.

Griffiths lost in his first match, by 10 frames to 13 against Steve Davis. Canadian Cliff Thorburn met the 1972 champion Alex Higgins from Northern Ireland in the final, which was a best-of-35-frames match. Thorburn won the match 18–16 to become the first world champion from outside the United Kingdom in the sport's modern era. There were 11 century breaks compiled during the championship, the highest of which was 136, achieved by both Kirk Stevens and Steve Davis. The cigarette manufacturer Embassy sponsored the tournament. It received 70 hours of television coverage by the BBC in the United Kingdom, attracting 14.5 million viewers for the conclusion of the final. Coverage of the final was interrupted by the broadcast of live footage of the Iranian Embassy Siege, which caused numerous viewers to complain to the broadcaster.
