Deruta is a hill town and comune in the Province of Perugia in the Umbria region of central Italy. Long known as a center of refined maiolica manufacture, Deruta remains known for its ceramics, which are exported worldwide.

Probably built upon Roman foundations, Deruta's name in its early variants (Ruto, Ruta, Rupta, Direpta and Diruta) all signify the “ruin” of this strategic site caused by the 6th-century Gothic War and the Lombard invasion. The Medieval commune that rose from these ruins had its own charter in the 13th century and was governed from its own Palazzo of the Consuls, but in fact Deruta has been under the dominion of neighboring Perugia since the 11th century, and has largely participated in Perugia's vicissitudes. The town's fortifications date from the 12th century, when it was an outpost in Perugia's marches, facing the rival town of Todi. In 1465, under a new agreement with Perugia, the magistrate sent from Perugia would govern with the consent of four local men of good character (quattro boni omini). The ravages of plague were so fierce at Deruta that rewalling in the later 15th century took in a smaller circuit to accommodate the reduced population. Besieged in 1408 during the confusion of the Papal Schism by the condottiere Braccio da Montone, and later heavily damaged by Cesare Borgia, Deruta was plundered by Braccio Baglioni, the master of Perugia. Thus in 1540, when the Papal forces of Pope Paul III ousted the Baglioni family from Perugia in the brief war over salt taxes locally called the "Salt War" (Guerra del Sale), Deruta sided with the papacy against Perugia, an alliance that gained it a reduction in taxes. With the papal reduction of Perugia, the region settled down to uneventful history as part of the Papal States.
