Valva is an Italian town and municipality in the Province of Salerno in the south-western region of Campania.

A flourishing town of the same name was present nearby at the time of the Roman Empire.

During Barbarian invasions the inhabitants built a new settlement, higher up the mountain; the ruins of this town, Valva Vecchia, can still be seen.

Sights include the church of San Giacomo, whose façade has three ornate portals in the late-Baroque style.

Cereals, fodder, olives and vegetables are grown and cattle, pigs and sheep are raised.
