The Florida State League is a Class A-Advanced minor league baseball league operating in the state of Florida.

The League is composed of two divisions—North and South—with six teams each. The League's regular season schedule runs from April to August with teams playing roughly 120 regular-season games, with the playoffs in September. Attendance averages around 500–1,000 per game.
