Castrocaro Terme e Terra del Sole is a comune (municipality) in the Province of Forlì-Cesena in the Italian region Emilia-Romagna, located about 60 kilometres (37 mi) southeast of Bologna and about 10 kilometres (6 mi) southwest of Forlì.

The comune consists of three small towns: Castrocaro, Terra del Sole and Pieve Salutare. Terra del Sole, founded as a 16th-century fortress by Cosimo I de' Medici, is believed to occupy the site of the ancient city of Solona, which lends its name to the town Tierra del Sole.
