The Memorial Cup is the national championship of the Canadian Hockey League, a consortium of three major junior ice hockey leagues operating in Canada and parts of the United States. It is a four-team round-robin tournament played among the champions of the Ontario Hockey League (OHL), Quebec Maritimes Junior Hockey League (QMJHL) and Western Hockey League (WHL), and a fourth, hosting team, which alternates between the three leagues annually. The Memorial Cup trophy was established by Captain James T. Sutherland to honour those who died in service during World War I. It was rededicated during the 2010 tournament to honour all soldiers who died fighting for Canada in any conflict.

The Canadian Hockey League is an umbrella organization that represents the three Canada-based major junior ice hockey leagues. The CHL was founded in 1975 as the Canadian Major Junior Hockey League, and is composed of its three member leagues, the Western Hockey League, Ontario Hockey League, and Quebec Maritimes Junior Hockey League. For the 2023–24 season, its three leagues and 60 teams represent nine Canadian provinces as well as four American states.
