Santa Fosca is a church in the sestiere of Cannaregio of Venezia, Italy.

Adjacent to the Strada Nova, it faces the campo of Santa Fosca.

On the campo stands the monument with a bronze statue of Paolo Sarpi, who was reported to have been stabbed here by papal mercenaries.

The facade (1733-1741), designed by Domenico Rossi, was built with the patronage of the patrician Donà family.

The interior has a Trinity and the Virgin by Filippo Bianchi; while the Life of Santa Fosca altarpieces were painted by Francesco Migliori.
