PalaBarbuto, also known by its sponsorship name of PalaEldo, is an indoor sporting arena located in Naples, Italy. The facility is located in Viale Giochi del Mediterraneo, in close proximity to the Olympic swimming pool Piscina Felice Scandone.

The arena was built and inaugurated in 2003, with a capacity of 4,000 seats, to host Basketball Napoli matches, due to the structural decay of the Mario Argento, located opposite on viale Giochi del Mediterraneo. Originally named after the sports reporter Lello Barbuto and now bearing the name of Eldo Megastore, a chain of Italian electronics mega stores, it is currently the home of the professional basketball teams Nuova AMG Sebastiani Basket of the Lega Basket and Eldo Napoli. In September 2006, its seating capacity was increased to 5,500 in order to comply with Euroleague arena requirements, which at that time required a minimum of 5,000 seats. In 2016, PalaBarbuto was closed for a number of games due to problems with electrical and fire safety systems.

In 2019, in view of the 2019 Summer Universiade, the facility underwent a profound restyling work: the parquet was replaced, as well as the lighting system, changing rooms and services. Safety measures were improved and the necessary interventions were carried out to make the upper grandstand usable again, bringing the arena's capacity back to 5,500 seats. In compliance with FISU requirements, two LED wall screens were installed, rented specifically for the event and removed at the end. Two new LED walls, similar to those used for the Universiade, were installed the following September, to replace the old luminous display board.
