Canadian athlete, sports executive, businessman and politician John Purcell "Percy" Quinn (1876–1944).

Born in Montreal, Quinn played lacrosse in his youth, and later moved to Winnipeg and then to Toronto.

In 1903, Quinn officiated the Stanley Cup challenge series between the Winnipeg Vics and the Montreal Hockey Club. Later he would become owner of early pro teams in Toronto, the Toronto Professional Hockey club and the Toronto Blueshirts, the latter club Stanley Cup champions in 1914.

Percy Quinn's younger brother Emmett Quinn (1877–1930) was also involved in early hockey matters as an executive, coach and referee.
