The Frank J. Selke Trophy, or simply the Selke Trophy, is awarded annually to the National Hockey League forward who demonstrates the most skill in the defensive component of the game. The winner is selected by a poll of the Professional Hockey Writers' Association following the regular season. Named after Frank J. Selke, former general manager of the Toronto Maple Leafs and Montreal Canadiens, the trophy has been awarded 45 times to 27 different players since the 1977–78 NHL season.

Francis Joseph Aloysius Selke was a Canadian professional ice hockey executive in the National Hockey League. He was a nine-time Stanley Cup champion with the Toronto Maple Leafs and Montreal Canadiens and a Hockey Hall of Fame inductee.
