Jayna Hefford is a Canadian retired ice hockey player and current chairperson of the Professional Women's Hockey Players Association.

The Professional Women's Hockey Players Association (PWHPA) is a nonprofit organization dedicated to advocating for the promotion of professional women's ice hockey. It was founded in May 2019 following the dissolution of the Canadian Women's Hockey League. PWHPA members expressed dissatisfaction with the operations of the existing professional National Women's Hockey League and vowed to boycott existing women's leagues and to work towards the establishment of a unified, financially sustainable professional league. From 2019 to 2023, the PWHPA organized a series of exhibition seasons, known as the Dream Gap tours, to generate support towards its goal.
