1981–82 snooker world rankings

The World Professional Billiards and Snooker Association (WPBSA), the governing body for professional snooker, first published official world rankings for players on the main tour for the 1976–77 season. Before this, for each tournament the defending champion was seeded first, and the previous year's runner-up second.

Players' performances in the previous three World Snooker Championships (1979, 1980 and 1981) contributed to their points total. For each of the three years, the World Champion gained five points, the runner-up received four, losing semi-finalists got three, losing quarter-finalists got two, and losers in the last-16 round received a single point. Players without any ranking points were listed in order of their performances at the 1981 World Snooker Championship. Cliff Thorburn, the 1980 champion, led the ranking list, with nine points, having been ranked second the previous year. The reigning champion, Steve Davis, held eight points and moved from thirteenth place to second, while the 1979 winner Terry Griffiths, also with eight points, rose from fifth to third. Ray Reardon, who had been ranked first in each of the five previous lists since the establishment of the rankings, was in fourth place with seven points, the same total as Dennis Taylor in fifth. The WPBSA deducted two ranking points from Alex Higgins's total for his behaviour at Herringthorpe Leisure Centre, Rotherham on 24 February 1981. Higgins had arrived late for the second of an exhibition match against Davis, reportedly because he was playing Space Invaders.

The top sixteen players in the rankings were seeded into the 32-player first round of the main competition for the 1982 World Snooker Championship. Janice Hale, a snooker reporter for The Daily Telegraph, wrote that the system, with points accumulated across three years, gave established players an advantage. An article in Snooker Scene magazine discussing the ranking list for 1980/1981, which was compiled on the same basis as the 1981/1982 list, had also contained concerns about the advantage to established players, while arguing that no better alternative system had been proposed. Player and commentator Jack Karnehm, who had previously criticised the ranking system for not taking into consideration players' performances at tournaments other than the world championship, agreed that no fairer system had been proposed. Karnehm published a "Supreme Snooker League Table" based on percentage of won in nine tournaments during the 1980–81 snooker season, which was headed by Steve Davis with 66.67% of frames won across 29 matches, followed by Willie Thorne who won 61.54% of frames in six matches. This method, in Karnehm's own assessment, produced rankings "every bit as unfair and inconsistent as the official ratings list".
