The Esaro is a river in the province of Cosenza, Calabria, southern Italy.[1] Its source is near Sant'Agata di Esaro. The river flows northeast near Roggiano Gravina before being joined by a left tributary, the Grondo, and a right tributary a short distance further. It then joins the Coscile as a right tributary of that river north of Spezzano Albanese, near the ancient site known as Interamnium. It is the main tributary of the Coscile.
