Joe Davis, OBE (born 15 April 1901 in Whitwell, Derbyshire, England; died 10 July 1978 in Hampshire) was a British professional player of snooker and English billiards.
Joe Davis became a professional billiards player at the age of 18, having won the Chesterfield Championship at age 13. In 1926 he reached his first World Professional Billiards Championship final but was unsuccessful against defending champion Tom Newman. He reached the final again the following year and was runner-up again to the same opponent. It was to be a case of third time lucky for Davis when he defeated Newman in 1928 to become the world champion at English billiards for the first time. He would defend his title for the next three years – against Newman again in 1929 and 1930 and New Zealander Clark McConachy in 1932. He contested the final two more times in 1933 and 1934 losing on both occasions to Australian Walter Lindrum.
Coinciding with his peak as a billiards player, Davis's interests shifted to snooker and he helped to organise the first snooker world championship in 1927 and won the tournament by beating Tom Dennis 20–10, for which he won UK£6 10s. He went on to win the world championship every year until 1940. Joe's brother Fred, twelve years his junior, was also a snooker player and multiple World Champion. When Joe met Fred in the world championship final of 1940, Joe won 37–36.
