The Western Canada League was the name of three different baseball circuits in Minor League Baseball that operated between 1907 and 1921.
The first instance of the league was a Class D circuit that played only in 1907 with four teams sponsored by four cities. The second instance was also a Class D league, which ran from 1909 through 1914 with 11 different cities represented in its six years of existence. The third instance started with four teams at the Class C level in 1919, expanded to six teams in Class B in 1920, and subsequently folded after the 1921 season.
