Chioggia (Italian: [ˈkjɔddʒa]; Venetian: Cioxa [ˈtʃɔza], locally [ˈtʃoza]; Latin: Clodia) is a coastal town and comune (municipality) of the Metropolitan City of Venice in the Veneto region of northern Italy.

The town is located on a small island at the southern entrance to the Venetian Lagoon about 25 kilometres (16 miles) south of Venice[4] (50 km (31 mi) by road); causeways connect it to the mainland and to its frazione, nowadays a quarter, of Sottomarina.

Chioggia was destroyed by King Pippin of Italy in the 9th century, but rebuilt around a new industry based on salt pans.

Other important modern industries include textiles, brick-making and steel; and Sottomarina, with 60 hotels and 17 campgrounds, is almost entirely given over to seafront tourism.

Because of the large number of people with the same surname, the comune officialized what is known as "detto" (popular nicknames used to distinguish the various branches of the same family).
