National Pro Fastpitch (NPF), formerly the Women's Pro Softball League (WPSL), was a professional women's softball league in the United States. The teams battled for the Cowles Cup.
The WPSL was founded in 1997 and folded in 2001; the NPF revived the league in 2004 and disbanded in 2021 after two cancelled seasons due to COVID-19. A new softball league, the Women's Professional Fastpitch (WPF), launched in 2022.
