The club was founded in 1921 as U.S. Piombino Calcio and spent three seasons in Serie B in which it defeated more famous teams such as A.S.Roma and Calcio Catania. The side disbanded in 1996 and was refounded as A.S. Piombino. It changed its denomination to the current one in 2004, but from the fans it's called as only "il Piombino".[1]
