Chioggia is a coastal town in the Veneto region of northern Italy (pop. 53,179 in 1991), on the Adriatic coast about 25 km south of Venice (50 km by road). It is situated on a small island on the southern side of the Lagoon of Venice; a bridge connects it to the mainland.

Important modern industries besides fishing, historically the most significant, feature textiles, brick-making and steel.

The Battle of Chioggia was a decisive naval battle between Venice and Genoa, fought in June 1380.
