Santa Maria in Grottapinta, Baroque church in Parione district, Rome, Italy.

Santa Maria in Grottapinta is a deconsecrated church in the Parione district, built on the foundations of an internal corridor of Pompey's Theater. Its small 19th-century facade is divided into two orders by a cornice, with Ionic pilasters and a lunette window; a small bell gable stands to the right. The interior is split into two superimposed halls of equal size, the upper retaining a barrel vault and the tops of its supporting pillars.

The church gained affiliation with the Basilica of San Lorenzo through a papal decree from Pope Urban III in 1186. This ecclesiastical connection shaped its standing and religious identity for centuries to come.

The name Grottapinta likely comes from a frescoed arch nearby, which Armellini thought resembled a painted grotto, following the Roman habit of calling ancient ruins grotte. A rival tradition traces it to a Madonna image found in a rocky cavity, perhaps a wing of Pompey's Theater. Since 1926 the deconsecrated church has served as a warehouse, now an exhibition and conference space.

The church is located at Via di Grotta Pinta in Rome's historic center and is easily accessible on foot. It functions as an exhibition and conference space, welcoming visitors interested in viewing the interior artworks.

The name Grottapinta possibly comes from painted decorations or from the Roman habit of calling ancient ruins grottoes. This linguistic origin ties the building directly to the archaeological layers beneath modern Rome.
