John James "Jolly Jack" Adams was a Canadian professional ice hockey player, coach and general manager in the National Hockey League and Pacific Coast Hockey Association. He played for the Toronto Arenas, Vancouver Millionaires, Toronto St. Patricks and Ottawa Senators between 1917 and 1927. He won the Stanley Cup twice as a player, with Toronto in 1918 and Ottawa in 1927, and was inducted into the Hockey Hall of Fame.

The 1918 Stanley Cup Finals was contested by the National Hockey League (NHL) champion Toronto and the Pacific Coast Hockey Association (PCHA) champion Vancouver Millionaires. In a series held entirely in Toronto, the Toronto team won the series by three games to two in the best-of-five game series to win the Stanley Cup. It was the first series contested by the new NHL and subsequently the first Stanley Cup win by the Toronto NHL franchise team.
