The WTA rankings are the Women's Tennis Association's (WTA) merit-based system for determining the rankings in women's tennis. The top-ranked singles player is the player who, over the previous 52 weeks, has garnered the most ranking points on the WTA Tour. Points are awarded based on how far a player advances in tournaments and the category of those tournaments. The WTA has used a computerized system for determining the rankings since November 3, 1975. Since 1975, 29 women have been ranked No. 1 in singles by the WTA, of which 15 have been year-end No. 1.
Iga Świątek is the current singles world No. 1.
