Saint Jerome church in Rijeka, Baroque Catholic church in Rijeka, Croatia

Saint Jerome is a church on Trg Riječke rezolucije whose late Baroque facade forms the eastern wing of the Municipij building. The interior holds Baroque altars: the main altar of 1744 is attributed to Antonio Michelazzi, and two side altars to the Capovilla stonemason workshop. On the south side of the sanctuary, Gothic buttresses and pointed-arch windows survive from the 14th-century building.

The building was founded in 1315 by the Devin Counts for the Augustinian order and served as an important religious center for centuries. After the 1750 earthquake, the interior was completely redesigned and acquired its present baroque appearance.

The cloister holds a lapidary of tombstones moved there in 1880, when a new floor was laid in the church and its 23 nave graves were removed. The slabs include the Raunacher tombstone, reset outside the Chapel of the Holy Trinity, an example of High Gothic carving.

The church stands on Trg Riječke rezolucije, its facade forming the eastern wing of the Municipij building. The cloister lapidary and the chapels of St. Trinity and the Immaculate Mary are reached through the monastery corridor. The presbytery holds the oldest section, with Gothic buttresses and pointed windows visible on the south side.

The main altar is dated 1744 and attributed to the sculptor Antonio Michelazzi; the late-17th-century altarpiece of the Virgin with Saint Jerome and Saint Augustine is by an unknown author. Behind the church, the apse and pointed Gothic windows survive from the 14th-century building.
