The Carolina League is a Minor League Baseball league which has operated along the Atlantic Coast of the United States since 1945. 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 East before reassuming its original moniker in 2022.
