The Isobel Cup is the championship cup awarded to the winner of the Premier Hockey Federation's annual playoffs. The championship is named for Lady Isobel Gathorne-Hardy who was not only one of the first women to play the sport of hockey but also the daughter of Lord Stanley of Preston, the namesake of the NHL's Stanley Cup.
The Boston Pride were the first club to win the Cup doing so after defeating the Buffalo Beauts 2-0 at Newark. In 2020 the Championship game, which was to be held between the Minnesota Whitecaps and Boston Pride, was cancelled due to the COVID-19 pandemic and no champion was crowned.
