The Central League was a minor league baseball league that operated sporadically in 1900, from 1903–1917, 1920–1922, 1926, 1928–1930, 1934, and 1948–1951. In 1926, the league merged mid-season with the Michigan State League and played under that name for the remainder of the season. The Central League later reformed in 1928.

The Central League hosted teams from 37 cities over its six decades of league play. Teams from the states of Indiana, Illinois, Michigan, Ohio, Pennsylvania and West Virginia were represented.
