San Proculo, previously dedicated to the saints Proculus and Nicomedes, is a Romanesque-style, Roman Catholic church located in Via de' Giraldi in Florence, Tuscany, Italy.

The building was renovated from 1739 to 1743, when it became the seat of the Confraternity of Sant'Antonio Abate dei Macellai, one of the four Flagellant brotherhoods known as buche, characterized by the practice of flogging, strict discipline, and night time prayer meetings.

San Procolo heals a boy by Gaetano Piattoli, is on the main altar.

Most of the other works of art previously in the church were moved to other sites or destroyed.

In 2018, Michel Elefteriades acquired the San Procolo church from the noble Salviati family, to make it an art gallery in which he would exhibit his medieval religious art collection and creations.
