Francis Michael "King" Clancy (February 25, 1902 – November 8, 1986) was a Canadian professional ice hockey player, referee, coach and executive.

Clancy played 16 seasons in the National Hockey League (NHL) for the Ottawa Senators and Toronto Maple Leafs.

[4] On October 11, 1930, coming off the most productive season of his career, with 17 goals and 40 points in 44 games with the Senators, Clancy was traded to the Maple Leafs, with Toronto manager Conn Smythe giving up $35,000 and two players in exchange for him.

The season after his retirement as a player, Clancy briefly coached the Montreal Maroons before beginning an 11-year stint as an NHL referee.

In 1949, the Montreal Canadiens hired Clancy to coach their American Hockey League (AHL) farm team, the Cincinnati Mohawks.

He was then appointed assistant general manager by his friend, Conn Smythe, although his responsibilities often involved public relations at least as much as building a hockey team.

Former Leafs player, coach, and assistant general manager Clarence Hap Day stated Clancy was paid to do nothing by both Smythe and Ballard.

Clancy was associated with professional hockey for 65 years at the time of his death, then the longest-such tenure in NHL history, and a record since surpassed by John Bucyk.

The King Clancy Memorial Trophy was named in his honour and is awarded annually to the NHL player who demonstrates leadership qualities on and off the ice and who has made exceptional humanitarian contributions in the community.

[12] His son, Terry Clancy, participated in ice hockey at the 1964 Winter Olympics and later played for the Toronto Maple Leafs.
