Badia di Sant'Agata or Abbey of St Agatha refers to an 18th-century Roman Catholic church and attached female convent located on Via Vittorio Emanuele #182 in the center of Catania, region of Sicily, southern Italy. The Baroque style church facade is across the street from the left transept of the Cathedral of Catania.

This monastery was founded in 1620, under the Benedictine rule, with an endowment by Erasmo Cicala. The church was erected at the site of a prior church and monastery that had been razed by the 1693 earthquake. The earthquake putatively killed 15 or the 28 nuns. The complex is dedicated the St Agatha of Sicily, patron of Catania and to whom over a half-dozen churches in town are also dedicated.
