San Jacopino church, Romanesque Revival church in San Jacopino district, Florence, Italy.

San Jacopino church, also called San Jacopo in Polverosa, is a Romanesque Revival church on via Benedetto Marcello 24, just outside Florence's centre. Architect Severino Crott designed it in 1931 and it was consecrated in 1936. It has rounded arches and symmetrical proportions typical of the style.

The church existed since the 13th century along the via Cassia, then called San Jacopo della Burella. In 1781 it became a parish, and in 1931 architect Severino Crott designed the current neo-Romanesque church, consecrated in 1936 by Cardinal Elia Dalla Costa. The old church, hit by a bombardment in 1944, was demolished.

The name San Jacopino comes from the church's small size: it was once called San Jacopo della Burella, and the diminutive stuck and passed to the surrounding quarter. A much-venerated crucifix with the mourning Virgin and Saint John the Apostle, brought from the destroyed church of San Pier Maggiore, was kept here.

The current church stands at via Benedetto Marcello 24, outside Florence's historic centre. From the new church, piazza San Jacopino is reached by walking via Cimarosa or via Bartolomeo Cristofori. The 1936 building replaced the older church on the piazza, which was demolished after the 1944 bombing.

The name San Jacopino is a diminutive of San Jacopo, referring to the church's small size; older sources also call it San Jacopo della Burella. The present building, consecrated in 1936, stands apart from the original medieval church, which was hit by a bombardment in 1944 and later demolished.
