The 1930 World Snooker Championship, known at the time as the Professional Championship of Snooker, was a snooker tournament held between 17 March and 23 May 1930 at various venues in England, with the final taking place from 19 to 24 May at Thurston's Hall, London. Defending champion Joe Davis won the title for the fourth time by defeating Tom Dennis by 25 frames to 12 in the final.
It was the fourth edition of the World Snooker Championship organised by the Billiards Association and Control Council. Six players participated in the tournament. One first round match was held at Newman's Club, London, and the venue for the other first round match and the semi-finals was Camkin's Hall, Birmingham. The highest break of the tournament was 79, a new championship record, compiled by Davis in the 12th frame of the final. Davis won both of his matches in the tournament by margins that meant the last day of play scheduled was not required. It was the third time in four years that Dennis was runner-up.
