Carcere dell'Ucciardone, Prison in Palermo, Italy.

The Carcere dell'Ucciardone, officially Casa di Reclusione Calogero Di Bona, stands on Via Enrico Albanese 3 near Palermo's port. A tall pale-ochre boundary wall with rounded coping encloses the complex; behind it rises a rectangular stone block with a shallow terracotta-tiled hipped roof, rows of small square windows above and taller arched openings below, plus a lower flat-roofed wing on the left.

The prison was designed in the early 19th century by Nicolò Puglia and reshaped to its present form by Palermitan architect Emmanuele Palazzotto (1798–1872). It began operating in 1842, when detainees were moved from the old Vicaria prison, which Palazzotto then converted into the Palazzo delle Reali Finanze. On 2 September 2014 it changed from a casa circondariale to a casa di reclusione, and on 8 January 2018 it was named after Calogero Di Bona, a custodial officers' marshal killed by the Mafia on 28 August 1979.

The name Ucciardone comes from the Sicilian dialect word 'u ciarduni', linked to the French word 'chardon', showing how different languages mixed in Sicily over time.

The complex is an active house of detention on Via Enrico Albanese 3, near the port and the Borgo Vecchio district, so it cannot be visited as a monument. The steel-and-concrete Aula Bunker, built for the Maxi Trial of the 1980s, is the part most often cited in accounts of the prison; access to it is arranged institutionally, not by tourists. Visitors can see the tall ochre perimeter wall and the tiled stone block from the surrounding streets.

In 2018, the facility was renamed after Marshal Calogero Di Bona, who was killed by organized crime in 1979. This renaming honors a law enforcement officer who fought against the Mafia in Sicily.
