The list of WTA number 1 ranked players shows the professional women's tennis players who have been or currently are ranked world No. 1 by the Women's Tennis Association, along with the dates of first reaching and losing that spot. Since the WTA began producing computerized rankings on November 3, 1975, 22 women have reached the highest singles ranking and 33 women the highest doubles ranking. The WTA Rankings are a merit-based method for determining the rankings in women's tennis and the WTA releases ranking points weekly based on how players fared during the previous 52 weeks.
