2018–19 PSA World Tour

The 2018–19 PSA World Tour is the international squash tour organised circuit organized by the Professional Squash Association (PSA) for the 2018 squash season. It's the 4th PSA season since the merger of PSA and WSA associations in 2015.

The most important tournaments in the series are the Men's and Women's PSA World Championship. The tour also features two circuits of regular events - PSA World Tour (formerly PSA World Series), which feature the highest prize money and the best fields; and PSA Challenger Tour with prize money ranging $5,500–$30,000. In the middle of the year, the PSA World Tour tour is concluded by the Men's and Women's PSA World Tour Finals in Cairo, the season-ending championships for the top 8 rated players from World Tour level tournaments.
