The official 2021/2022 snooker world ranking points for the professional snooker players on the World Snooker Main Tour in the 2021–22 season are based on performances in ranking tournaments over a two-year rolling period. The rankings at the start of 2021/2022 season are determined by prize money earned in the 2019/2020 and 2020/2021 seasons and are updated after every tournament carrying ranking status; the players are re-ranked at the beginning of the current season after removing players relegated at the end of the previous season from the ranking list. As points are accrued from tournaments throughout the current season, the points from the corresponding tournaments from two seasons earlier are dropped. The rankings are used to set the official tournament seedings at various points throughout the season; even though the rankings are officially updated after every tournament carrying ranking status not all the rankings are used as seedings, and only the rankings officially used as seedings are documented below. The total points accumulated by the cut-off dates for the revised seedings are based on all the points up to that date in the 2021/2022 season, all of the points from the 2020/2021 season, and the points from the 2019/2020 season that have not yet been dropped.
^"Ch" = Change since the beginning of the 2021/2022 season. See [4] for the player rankings at the start of the season
^The 2019/2020 points only include the ranking points that count towards the next seedings update. All new players or players regaining a place on the tour started on 0 points.
^Under World Snooker's rules players are not generally awarded points if they qualify for an event and then withdraw. However, World Snooker's appeals committee reserves the right to award points at their discretion and occasionally the finalised ranking list published after the tournament is inconsistent with the provisional list updated by the WPBSA during the tournament, in the event that discretionary points have been awarded. In such instances this table might include points not documented on the WPBSA's provisional list, which have been factored into the table so the overall totals and rankings match those on the finalised ranking list.
