The 1929 World Snooker Championship, known at the time as the Professional Championship of Snooker, was a snooker tournament held between 17 December 1928 and 7 March 1929 at various venues in England, with the final taking place from 4 to 7 March 1929 at the Lounge Hall, Nottingham. Defending champion Joe Davis won the title for the third time by defeating Tom Dennis by 19 frames to 14 in the final, after securing a winning margin at 17–12.

Joseph Davis was an English professional snooker and English billiards player. He was the dominant figure in snooker from the 1920s to the 1950s, and has been credited with inventing aspects of the way the game is now played, such as break-building. With the help of equipment manufacturer Bill Camkin, he drove the creation of the World Snooker Championship by persuading the Billiards Association and Control Council to recognise an official professional snooker championship in 1927. Davis won the first 15 world championships from 1927 to 1946, and he is the only undefeated player in World Snooker Championship history. In 1935, he scored the championship's first century break.
