The WSA World Series (formerly known as the WISPA World Series) is a series of women's squash tournaments which are part of the Women's Squash Association (WSA) World Tour for the 2014 squash season.

Each year, several tournaments on the tour are designated World Series events.

Then, early the next year, the eight best-performing players from the World Series events are invited to compete in the WSA World Series Finals (a similar event to the WTA Tour Championships).

Points for this are calculated on a cumulative basis after each World Series event.

In the same time, the players competing in WSA World Series Events earn world ranking points according to the prize money, classification of the event, and the final position in the draw the player reaches.
