Women's Pro Baseball League

The Women’s Pro Baseball League (WPBL) is a professional women's baseball league in the United States. Co-founded by Justine Siegal and Keith Stein, the league commenced its first season on August 1, 2026 with four initial teams representing four cities across the United States: the Boston Hunters, New York Heights, Los Angeles Queens, and San Francisco Firebells. Robin Roberts Stadium in Springfield, Illinois, will serve as a neutral venue for all games played during the inaugural season.

The league was founded in 2024 with an aim to elevate the visibility and proliferation of women's baseball, by establishing a path to professionalism for college and amateur players. It will be the fifth American professional women's baseball league, after the All-American Girls Professional Baseball League (1943–1954), National Girls Baseball League (1944–1954), International Girls Baseball League (1952–1953), and Ladies League Baseball (1997–1998). It has no association with Major League Baseball. Maybelle Blair, Cito Gaston, Digit Murphy, and Ayami Sato assisted in the league's initial development. The league's competitions, played during summer, consist of a regular season and a postseason. Games last seven innings, and are played with aluminum bats. Teams consist of 15–25 players. The league intends to broadcast its games on a national network, instead of on regional sports networks.
