John Purcell Quinn (January 9, 1876 – October 28, 1944) was a Canadian athlete, businessman, sports executive and politician.

He was referee of the Stanley Cup challenge series between the Winnipeg Victorias and the Montreal Hockey Club in 1903.

Quinn and Livingstone knew each other from managing the Toronto Amateur Athletic Club's ice hockey team in previous years.

In 1918, Livingstone and Quinn would team up against the owners of the NHA, now operating as the National Hockey League (NHL).

[4] Quinn bought an option for the dormant Quebec city franchise of the NHA/NHL and was named a director of the NHL.

In this position, he along with Livingstone attempted again to form a new league, one that would have two teams in Toronto, one in Hamilton and one possibly in the United States; either in Boston, Cleveland or Detroit.

[6] Quinn was a member of the Montreal Shamrocks team that won the world championship in 1896.
