The 1931 World Snooker Championship was a snooker tournament held at the Lounge Hall in Nottingham, England from 27 April to 1 May 1931. Despite increasing interest in the game of snooker, only two players entered the competition for the title: defending champion Joe Davis and three-times runner-up Tom Dennis. It was the fifth time that the World Snooker Championship had been contested since its inception in 1927. Davis won his fifth World title by defeating Dennis 25–21. Dennis led 19–16 at one stage but Davis won 9 of the next 11 frames to take the title. The highest break of the match was 72, compiled by Davis in the 41st frame.
