The Walter Cup is the championship trophy awarded to the winner of the Walter Cup playoffs, which culminate in an annual best-of-five series that determines the champion of the Professional Women's Hockey League (PWHL). The trophy is named in honour of PWHL co-founders and spouses Mark Walter and Kimbra Walter. Two teams have won the Cup since its establishment: the Minnesota Frost in both 2024 and 2025, and the Montreal Victoire in 2026.
