The Official Men's Squash World Ranking is the official world ranking for men's squash. The ranking is to rate the performance level of male professional squash player. It is also a merit-based method used for determining entry and seeding in men's squash tournaments. The rankings are produced monthly. The current world number one is Grégory Gaultier of France, who replaced Mohamed El Shorbagy in April 2017.

Players competing in PSA tournaments earn ranking points according to how far they get in the draw. The points available depend on the prize money and the draw size. The monthly rankings (issued on the 1st of the month) are used in selecting entries to tournaments and in determining the seeds.

The total number of points a player earns in the previous twelve months is divided by the number of tournaments played (a minimum divisor of ten is used) to give a ranking average. Where a player has played more than 10 tournaments the best scores may be selected (i.e. the lowest are not included) according to the Averaging Formula. (See table below.)

For example, a player who has competed in 14 events will have his best 11 scores used. These will be accumulated and divided by 11.

Players competing in PSA World Tour Events earn ranking points according to the prize money, classification of the event, and the final position in the draw the player reaches.

A divisor is selected based on the number of tournaments played during the year as shown in the table below (the minimum divisor is ten). The average is calculated from the highest points scored for this number of events over the past twelve months:

Note: The monthly ranking for the men's squash (world ranking) is taken directly from the Professional Squash Association (PSA) official website.
