San Procolo is an early Gothic-style, Roman Catholic church and former monastery-hospital located on Via Massimo D'Azeglio #52 in central Bologna, region of Emilia Romagna, Italy.

To the right of the entrance, the first altar has a depiction of the Crucifixion with Sant'Andrea, Magdalen, and San Giovanni attributed to Giacomo Lippi (Jacopone da Budrio), moved her from the deconsecrated Sant Andrea degli Ansaldi.

This altar once held a painting by Giovanni Battista Grati (1651-1758) a pupil of Mattioli, Pasinelli, and Dal Sole, and member of the Accademia Clementina.

In 1764, the chapel was refurbished with an altarpiece by Pietro Maria Scandellari, and decorated by Raimondi Compagnini, Gaetano Caponeri, and Lorenzo Pranzini with prospective design of Antonio Galli Bibiena.

The choir was designed by Giulio Dalla Torre and Carlo Francesco Dotti, with paintings by Giuseppe Pedretti depicting the Martyrdom of St Proculus.

The first chapel on the left, holding since the 13th century the relics of both the martyrs Proculus of Bologna and Pozzuoli, was refurbished in 1750 by Alfonso Torreggiani and Antonio Cartolari.
