The 1939 World Snooker Championship was a snooker tournament held at Thurston's Hall in London, England from 23 January to 4 March 1939. It was the thirteenth edition of the World Snooker Championship. Joe Davis retained the championship title that he had held since 1927. In the best-of-73-frames final against Sidney Smith, Davis won the match 43–30, securing the victory at 37-25 earlier in the match. Fred Davis set a new championship highest break by compiling a 113 in the 22nd frame of his 14–17 semi-final defeat by his brother Joe Davis.
There were fifteen participants, with four players taking part in a qualifying competition for a place in the twelve-person main event. Walter Donaldson, who entered the championship for the first time since his debut in 1933, won the qualifying event, and eliminated Claude Falkiner, a tournament debutant who was taking part in his first cue sports tournament for several years, in the first round of the main draw, before losing in the quarter-finals to Sidney Smith.
