Cappella della Mater Boni Consilii, Neoclassical chapel in Rome, Italy.

The Cappella della Mater Boni Consilii is a small chapel on Via Salita del Grillo in the Monti district of Rome. Its facade has a wide round-arched portal framed by pilasters and topped by a triangular pediment. Inside is a narrow single room with an altar crowned by an icon of the Madonna and hung with several ex-votos.

The chapel is documented through Mariano Armellini's 1891 survey of Rome's churches, which describes it as a simple oratory. A later account by Antonio Venditti links the chapel to the Madonna del Buon Consiglio devotion at Tor de' Conti in the Monti district. The sources record no construction date or architect.

The chapel is dedicated to Our Lady of Good Counsel, and its altar is crowned by an icon of the Madonna, surrounded by ex-votos left by the faithful. Mariano Armellini described it in 1891 as a very simple oratory, and the name Mater Boni Consilii is the Latin form under which the dedication is recorded.

The chapel stands on Via Salita del Grillo, a stepped lane climbing from the Forum area up into Monti; visitors reach it on foot, and the surrounding streets are narrow and uneven. It is a small oratory, so only a few people fit inside at once.

The chapel is also known as the Cappella della Madonna del Buon Consiglio a Tor de' Conti, and Antonio Venditti wrote an article about it. Mariano Armellini described it in 1891 as a simple oratory. The interior is a narrow space with an altar crowned by an image of the Madonna and filled with ex-votos.
