Chiesa di San Fantin

San Fantin (short for San Fantino) is a church in the sesteiere of San Marco in Venice, Italy. It stands in front of the Fenice Theater and adjacent to the Ateneo Veneto (former Scuola grande di San Fantin).

This parrochial church was first erected in the tenth century under the patronage of the patrician families from Barozzi, Aldicina, and Equilia. Reconstruction was pursued by the Pisani family, who installed in the church a miraculous icon of the Virgin they had obtained from the East. The church of San Fantin by the 1400s became called the church of Santa Maria delle Grazie di San Fantino. Ten thousand ducats were willed for the church's reconstruction by Cardinal Giovanni Batista Zeno in the 1501. A number of relics were transferred to this church including the body of Santa Martire Marcellina and an armbone of the Martyred Saint Trifone, Protector of Cattaro.

Work on the church has been assigned or attributed to many architects, from Pietro Lombardo, Sebastiano Mariani, and later Jacopo Sansovino. Over the door of the sacristy is conserved the funeral urn of Vinciguerra Dandolo, a work by Tullio Lombardo. In 1908, the church was documented to hold two Piazzetta paintings: Liberation of Venice from the Pest and a Pieta. It had a Holy Family attributed to Giovanni Bellini, a Crucifixion by Lionardo Corona, and a Visitation of Mary to Elizabeth by Tintoretto. These works have been relocated elsewhere.
