Angelo Alessio (born 29 April 1965 in Capaccio) is an Italian football manager and former player.
After retirement, Alessio joined Napoli as a coaching staff member, first in charge of the youth teams and subsequently as a first team assistant. He then served as head coach for a number of Serie C2 teams (Imolese, Massese, SPAL); however it was not until his combination with Antonio Conte at Siena where his talents were truly noticed.
