The California State League is a minor baseball league operating in California and the Pacific coast. While there were at least three Class D California State Leagues that operated at different points in minor league baseball history, two of the leagues (1910 and 1929) existed for only a single season. The third league operated for three seasons, from 1913 to 1915.

The 1910 version was Class B until 6 June 1910, after which it became Class D. Sacramento and San Francisco dropped out on 31 May 1910, and Oakland moved to Merced on 7 June 1910. Fresno then disbanded 24 June 1910, causing the league to cease operations.

The league was re-established for the 1913 season, then disbanded again on 1 June 1914. When it was re-established again in 1915, the league would be disbanded on 30 May due to inclement weather and the teams having played only 5 to 7 games.

The 1929 league, which was based in Southern California, lasted until 17 June, where teams played around 50 games.
