The Frank J. Selke Trophy is an annual award in the National Hockey League (NHL) that honors the best defensive forward. Established in 1978, it recognizes players who excel in their defensive responsibilities while contributing to their team's offensive play. The trophy is named after Frank J. Selke, a former general manager of the Montreal Canadiens. The winner is determined by a vote among the members of the Professional Hockey Writers' Association at the end of each regular season. Players are evaluated based on their overall defensive skills, faceoff percentage, and contributions to their team's success.
