The Can-Am Senior B Lacrosse League is a Senior-level box lacrosse league with teams in the Western New York and Central New York regions of New York State and southern Ontario in Canada, mostly on tribal reservations of the Iroquois Confederacy. Sanctioned by the First Nations Lacrosse Association, the champions of the Can-Am league compete for the Presidents Cup, the Canadian National Senior B championship. Can-Am teams have won the Presidents' Cup five times.
Formed in 1969 as the North American Lacrosse Association, the league reformed after eight seasons. Renamed Can-Am in 1978.
Newtown Golden Eagles are the most successful team to-date winning the Can-Am title 11 times. The Eagles have medaled at Presidents' Cup three times, including gold in 2000.
