The club was founded in 1948 as Felice Scandone Sports Society (S.S.), merging with Libertas Avellino two years later and CSI-Cestistica Irpina in 1968. After going between leagues from 1974 to 1995, the club settled in
Serie B1. Two seasons later, coach
Gianluca Tucci guided the team to the second division
Serie A2. The turn of the millennium saw the side reach the first division
Serie A, placing ninth in 2001 at the end of their debut season. The next seasons were more complicated, with finishes of 14, 15, 16 and 12th place. When coach
Zare Markovski, who had been coaching the side since 2002, left in 2005, the club ended the season in 17th place and should have been relegated if not for promoted
Roseto's inability to play in the Serie A.
Matteo Boniciolli took over coaching duties following that season and kept Avellino away from the relegation places. The 2007–08 season saw Boniciolli lead Avellino to their best ever league finish of tied second-best with a 23–11 record and a league MVP title for
Marques Green, their playoffs run was cut short in the semifinals by
Lottomatica Roma (the side who had finished joint second) after they had swept
Capo d'Orlando in the quarterfinals. Even better for the side, players such as Green,
Devin Smith and
Eric Williams led Air Avellino to its first ever title ever, the 2008
Italian Cup, in its first participation in the competition, after beating
La Fortezza Bologna 73–67 in the final with 18 points from the game MVP Smith. The team joined the
Serie B Basket, the national third level. In July 2021 the club was declared bankrupt and ceased its sporting activities. An unrelated club named
Del Fes Avellino was named in the same year. Club logos and sporting legacies were at disposal of the bankruptcy trustee before getting acquired by a brand new legal entity in 2023, under the name of
S.S. Felice Scandone Avellino 1948. ==Honours==
