The Alberta-British Columbia Senior League is a defunct senior men's ice hockey league that operated for the 1941-42 season.
The West Kootenay League was a senior level hockey league that operated from 1922-23 through 1940-41; and the Alberta Senior Hockey League was a senior level league that operated between 1936 and 1941. Both leagues suspended their operations after the 1940-41 season due to World War II.
For the 1941-42 season, four teams from the two leagues (along with the upstart Red Deer Buffalos), merged to form the Alberta-British Columbia Senior League. Due to the pressures of the war, the league lasted just one season.
The West Kootenay League was resurrected for the 1945-46 season, and in 1946-47 the league expanded into the United States to become the Western International Hockey League.
