Capriccio: St Paul's and a Venetian Canal is 1795 oil painting by the British artist William Marlow.

A capriccio, it portrays an imagined scene featuring a canal in the Republic of Venice and St Paul's Cathedral in the City of London.

[2] Canaletto had been a pioneer of the capriccio, which blended multiple buildings in an imagined and often contrasting view.

Marlow's work was produced not long before the Fall of the Republic of Venice to the forces of the young Napoleon.

[4] Today it is in the collection of the Tate Britain in Pimlico having been purchased in 1954.
