The Dogado or Duchy of Venice is the word used to define a Doge's reign and the name given to the homeland of the Republic of Venice, headed by the Doge.

This term is equivalent to Ducato (duchy), the term given to Italian city states that (unlike Venice) have a duke as hereditary head of state.

It comprises the city of Venice and the narrow coastal strip from Loreo to Grado, though these borders later extend from Goro to the south, Polesine and Padovano to the west, Trevisano and Friuli to the north and the mouth of the Isonzo to the east.

Apart from Venice, the capital and in practice a city-state of its own, the administration of the Dogado is subdivided in nine districts starting at the north: Grado, Caorle, Torcello, Murano, Malamocco, Chioggia, Loreo, Cavarzere and Gambarare.

In lieu of the earlier tribunes (elected by the people) and gastalds (corresponding with the Doge), during the Republic each district is led by a patrician with the title of podestà, with the exception of Grado, headed by a Count.

It is one of the three subdivisions of the Republic's possessions, the other two being the Stato da Màr ("Sea State") and the Domini di Terraferma ("mainland

domains").
