Palazzo Corner, Mannerist palace in San Marco, Italy.

Palazzo Corner della Ca' Granda is a Renaissance palace by Jacopo Sansovino on the Grand Canal in San Marco, between Palazzo Minotto and the Casina delle Rose. Its Istrian stone ground floor has three round arches opening onto a portico, flanked by aedicules with banded columns and circular pediments. Above, two noble floors each carry a central triple-arched window with paired columns and single windows to the sides, Ionic below and Corinthian above, with human heads carved on the keystones.

The previous Malombra palace on the site was bought in 1478–1480 by Giorgio Corner, brother of Caterina, queen of Cyprus. After a fire in 1532 destroyed it, his descendants commissioned Jacopo Sansovino and Scarpagnino in 1537; Sansovino's design was one of his first Venetian commissions. In 1817 Andrea Corner sold the palace to the Austrian Empire, and from 1866 it housed the province of Venice and the prefect.

The building stands at a point where several canals meet, giving its former residents a visible position along the main water routes. The facade was designed to be seen from boats, since water was the primary way of moving through the city.

The building sits directly on the Grand Canal and is best seen from the water, for example from a vaporetto. The nearest stop is Sant'Angelo, just a short walk away along the canal path.

The palace passed to the Austrian Empire in 1817 after a second fire, when Andrea Corner sold it; Vienna installed the Provincial Delegation and later the Imperial Lieutenancy. From 1866, with the Veneto annexed to Italy, it housed both the province of Venice and its prefect, a role it still holds.
