Lina Ljungblom med första svenska målet i PWHL

The Professional Women's Hockey League (PWHL; French: Ligue professionnelle de hockey féminin, LPHF) is a professional women's ice hockey league in North America, wholly owned and operated by the Mark Walter Group. It consists of six franchises, three each from Canada and the United States, who play a regular season to earn one of four places in a postseason tournament that determines the winner of the Walter Cup. Differences between the PWHL and other North American professional hockey leagues include a 3-2-1-0 points system, terminations of penalties following a short-handed goal, best-of-five shootouts, and greater restrictions on body checking. The league's matches are broadcast nationally in Canada by the CBC and TSN, their French-language affiliates Radio-Canada and RDS, and Sportsnet. In the United States, it is broadcast in syndication, while worldwide it is streamed on YouTube. The collapse of the Canadian Women's Hockey League in 2019 led to the establishment of the Professional Women's Hockey Players Association (PWHPA), a non-profit organization that advocated for greater professionalism in women's ice hockey. PWHPA members boycotted existing leagues, including the Premier Hockey Federation (PHF), with the goal of establishing a stable, unified professional league, and worked to build a collective bargaining agreement with Mark Walter and Billie Jean King Enterprises. The Mark Walter Group acquired the assets of the PHF following its 2022–23 season. Subsequently, the PWHPA worked with the Mark Walter Group to establish a unified league with new ownership and management. The league's first draft took place in September 2023, and its first season began in January 2024.
