The church of San Marcuola is a religious building facing the Grand Canal and located in the sestiere of Cannaregio in Venice, Italy.

It is dedicated to the saints Hermagoras and Fortunatus ("Marcuola" is a Venetian contraction of "Ermacora").

The church has a large collection of statues by Gaetano Susali, and paintings by Francesco Migliori.

For the right side, Tintoretto painted Christ Washing the Disciples' Feet but it is now at either Museo del Prado in Madrid or the Shipley Art Gallery.

The grave of 18th century German composer Johann Adolph Hasse is located in San Marcuola.
