Angelo Alessio (born 29 April 1965 in Capaccio) is an Italian football manager and a former player, who is manager of Kilmarnock.
A central midfielder, Alessio started his professional career as a player with then-Serie A club Avellino in 1984. He was then signed by Italian powerhouse Juventus in 1987, with whom he played until 1992 (except for a season loan at Bologna in 1988–89). He then moved to Serie A club Bari, before to join Cosenza in the Serie B and then returning to Avellino (now in Serie C1) in 1997. He ended his career in 1998 after a season with Modena.
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.
