The California League is a Minor League Baseball league that operates in California. Having been classified at various levels throughout its existence, it operated at Class A-Advanced from 1990 until its demotion to Single-A following Major League Baseball's 2021 reorganization of the minor leagues. The league temporarily operated for the 2021 season as the Low-A West before reassuming its original moniker in 2022.

Before the COVID-19 pandemic, league attendance continued to increase each season, with over one million fans attending games per year, part of a general nationwide growth and expansion to smaller towns, cities, and regions below those in the National League or American League with Minor League Baseball at various levels of play in growing popularity in the last few decades.
