The 1971 World Snooker Championship was a professional snooker tournament that took place between 28 September and 7 November 1970 in Australia. The tournament was the 1971 edition of the World Snooker Championship, first held in 1927 but was held in 1970. It was the first time the event had been held outside England outside of two challenge matches in 1965, with matches held at various locations in New South Wales and Brisbane. The event featured nine participants, with a round-robin round producing four qualifiers, who then competed in a single-elimination tournament.
Ray Reardon was the defending champion, having defeated John Pulman in the 1970 final, however Reardon lost to John Spencer in the semi-final. Spencer won the event for the second time by defeating Warren Simpson 37–29 in the final held in the Chevron Hotel in Sydney. Eddie Charlton made the highest break of the tournament with a 129 in the final session of his round-robin match against Gary Owen.
