Bernardo Bellotto (January 30, 1720 — October 17, 1780) was an Italian urban landscape painter or vedutista, and printmaker in etching famous for his vedutes of European cities (Dresden, Vienna, Turin and Warsaw). He was the pupil and nephew of Canaletto, and sometimes also used the latter's illustrious name, thus signing as Bernardo Canaletto – illegally according to some. Especially in Germany, paintings described as by Canaletto may be his rather than his uncle's.

His style was characterized by elaborate representation of architectural or natural vistas, as well as the specific quality of each place's lighting. Like his uncle and many other Venetian masters of vedute, he used the camera obscura in order to achieve the superior precision of his urban views.
