The Oratorio di Sant'Ilrico (Oratory of Saint Hilarius) is a Baroque style, former-Roman Catholic oratory, that can be also described as a small church or independent-standing chapel, located at strada Massimo d'Azeglio #43, in the Oltretorrente quarter of Parma, Italy.
The oratory is located within the Ospedale Vecchio (old civic hospital) with the entrance sandwiched among the porticoes of facing the strada.
The oratory was moved to a hospital here, dedicated to aiding the poor and infant orphans (Ospedale della Misericordia e delle Esposti).
The vault of the same was painted by Giovanni Maria Conti della Camera aided by Francesco Reti and Antonio Lombardi Parmigiani between 1664 and 1666.
To the left of the main altar was incorporated the monument of the founder of the Ospedale della Misericordia, Rodolfo Tanzi.
