Diocese of Nusco was a Roman Catholic ecclesiastical territory in Campania, southern Italy, existing until 1986. In that year it was united into the archdiocese of Conza-Sant'Angelo dei Lombardi-Bisaccia, to form the Archdiocese of Conza-Sant'Angelo dei Lombardi-Nusco-Bisaccia. It was a suffragan of the archdiocese of Salerno.
Nusco is in the province of Avellino. The diocese dates from the eleventh century. Among its bishops were
Guido (1004);
St. Amatus of Nusco (1167), author of a history of the Normans in Apulia and Calabria;
Roger (1198), who restored the cathedral;
Cardinal Pietro Paolo Parisio (1538), who presided at the Council of Trent;
Francesco Arcudio (1639), a Theatine;
Fulgenzio Arminio Monforte (1669), an Augustinian.
In 1820 the diocese of Montemartino was united to Nusco. St. John, a Benedictine (1084) was the first Bishop of Montemartino; forty of his successors are known.
