The Lady Isobel Gathorne-Hardy Cup, often shortened to Isobel Cup, is the championship trophy that was awarded annually to the now defunct Premier Hockey Federation (PHF) playoff winner. The trophy is named after Lady Isobel Gathorne-Hardy, the daughter of Lord Stanley—former Governor-General of Canada and namesake of the Stanley Cup—and one of the first women known to play the game of ice hockey.
The Isobel Cup was last awarded in 2023. After the 2022–23 season concluded, the PHF was bought out as part of the process of establishing the new Professional Women's Hockey League (PWHL), leaving the Isobel Cup's status in limbo.
