Palazzo Smith Mangilli Valmarana is a palace in Venice, located in the Cannaregio district and overlooking the Grand Canal.

[2] The palazzo is best known for having been the residence of the English consul Joseph Smith, who was Canaletto's agent to sell his paintings to the British customers.

[5] The palace was originally a Gothic Byzantine building, but when it became the seat of the English embassy and the residence of Smith, he altered the structure according to the taste of the time: in 1743, painter and engraver Antonio Visentini designed the new facade; the work lasted until 1751.

In 1784, the palace passed to Count Giuseppe Mangilli, who added the above floors and invited Giannantonio Selva to decorate the interiors.

Selva created a luxurious and unified series of rooms in neoclassical style, still perfectly preserved today.
