Rovigo (Italian pronunciation: [roˈviːɡo] ⓘ, Venetian: [ɾoˈviɡo]; Emilian: Ruig) is a city and commune in the region of Veneto, Northeast Italy, the capital of the eponymous province.

Polesine is the name of the low ground between the lower courses of the rivers Adige and Po and the sea; the derivation of the name is much discussed, generally applied only to the province of Rovigo, but is sometimes extended to the near towns of Adria and Ferrara.

Rovigo (both Rodigium and Rhodigium in Latin script) appears to be first mentioned in a document from Ravenna dating April 24, 838; the origin of the name is uncertain.

In 920 it was selected as his temporary residence by the bishop of Adria, Paolo Cattaneo, after the destruction of his city by Hungarian marauders; the fortifications he ordered were already finished in 945.

In the 1950s and 1960s Rovigo had a dramatic development and it had the highest urbanization rate among the towns in the Veneto region after World War II.
