The Castello Normanno ("Norman Castle"), or alternatively the Castello di Aci ("Castle of Aci"; Sicilian: Casteddu di Iaci), is a castle in Aci Castello in the Metropolitan City of Catania in Sicily, southern Italy. The castle is situated on a rocky outcrop jutting out into the sea. Its precise date of construction is uncertain, but it was important to the development of its region during the Middle Ages. During the War of the Sicilian Vespers, it was subject to Roger of Lauria. It was besieged more than once, and was briefly controlled by the Spanish. It is currently a museum.
