Vietri sul Mare is a town and comune in the province of Salerno, in the Campania region of southern Italy. It is situated just west of Salerno, separated from the Port of Salerno by only a harbour wall. The town is known for its polychrome ceramics, a tradition since at least the 15th century, and is considered to be the gateway to the Amalfi Coast.
The main landmark is the Church of St. John the Baptist, a late Neapolitan Renaissance style building with a high bell tower. There are numerous buildings displaying ceramics, including the Museo Provinciale della Ceramica in the nearby village of Raito.
