San Bonaventura, Catholic church in Cannaregio, Venice, Italy

San Bonaventura is a church building in the Cannaregio district of Venice featuring architectural elements from the 17th century. The structure displays the simple yet expressive design typical of Venetian religious buildings from that period.

San Bonaventura was built in 1620 by the Reformed Franciscan friars from the island of San Francesco del Deserto, together with a monastery. The Napoleonic suppression of religious orders closed the church in 1810 and the monastery was demolished. In 1859 Countess Paolina Giustinian-Recanati bought the complex and had a convent of Discalced Carmelites built, with the church as its chapel; in the early 20th century part of the convent became a children's hospital.

The church is named after Saint Bonaventure, the 13th-century Franciscan theologian and cardinal bishop. Since 1859 it has served as the chapel of the convent of Discalced Carmelite nuns founded by Countess Paolina Giustinian-Recanati, who bought the complex that year.

The location is in Cannaregio and is reachable from several water transportation stops. Visitors should remember that this is an active religious center and respect for ongoing services is required.

The church once held Tintoretto, Jacopo and Leandro Bassano, and Tiepolo's Santa Margherita da Cortona; the Tiepolo was moved to San Michele in Isola, and other works reached the Gallerie dell'Accademia. The stripped interior and bare facade are what remain.
