Palazzo di Giustizia, Courthouse in Poggioreale, Naples, Italy.

The Palazzo di Giustizia is a judicial complex beside Naples' Centro direzionale, with its main entrance on Piazza Falcone e Borsellino. Its main body consists of three towers, A, B and C, between 70 and 110 metres tall, flanked by two secondary blocks of 41 and 44 metres. At 18 metres the three towers are joined by a large covered square.

The 1957 law no. 309 already planned to enlarge the Naples tribunal at Castel Capuano, and a 1966 law called for a new Palazzo di Giustizia on a site still to be chosen. Construction began in 1980 with a spending cap of 16 billion lire set in 1970, was halted by the Irpinia earthquake and again in 1990 by an arson fire described as the largest blaze ever in Italy. The building became fully operational on 6 November 1995, when trials moved from Castel Capuano; Mededil, of the IRI-Italstat group, built it.

The building's name is tied to its role as Naples' single judicial citadel: since 6 November 1995 trials moved here from Castel Capuano, the old courthouse. The complex is not part of the adjacent Centro direzionale, though Mededil, the IRI-Italstat company that built the whole business district, also built the courthouse.

The main entrance is on Piazza Falcone e Borsellino, and the public may also use the entrance on Piazza Porzio; the entrances on via Grimaldi and via Aulisio are reserved. Inside, judicial staff and lawyers follow routes separate from the public. The complex sits beside the Centro direzionale, which it is not part of.

The building features a distinctive covered plaza at 18 meters height connecting the three main towers, serving as a central meeting point and transit space for users of judicial services.
