The WTA 1000 tournaments are a category of tennis tournaments on the WTA Tour, governed by the Women's Tennis Association. The old WTA Premier Mandatory and 5 tournaments merged into a single highest tier implemented in the 2021 schedule reorganization. Until 2024, only four of the nine WTA 1000 tournaments were mandatory, when the category expanded to ten mandatory tournaments.

The WTA Finals is the season-ending championship of the WTA Tour. It is the most significant tennis event in the women's annual calendar after the four majors, as it features the top eight singles players and top eight doubles teams based on their results throughout the season.
