The Roman Catholic Diocese of Campagna was twice been a Latin suffragan bishopric with see in Campagna, a town in the Salerno province of Campania region, southern Italy.

Its former cathedral episcopal see is now a co-cathedral: the Minor basilica of Santa Maria della Pace (dedicated to Our Lady of Peace).

A first Diocese of Campagna was established on 19 July 1525, on territories split off from the Metropolitan Archdiocese of Salerno and the Diocese of Satriano, the bishop of that see cumulated as first Bishop of Campagna, and his successors continued to do so.

On 27 June 1818, it was suppressed and its territory (not the title) merged into the Diocese of Sant’Angelo dei Lombardi–Bisaccia.

On 30 September 1921, a (second) Diocese of Campagna was 'restored' on territory split off from the then Metropolitan Archdiocese of Conza, but administered by the same Conza 1818.06.27–1921.09.30 under that Metropolitan as Apostolic Administrators until 1921.

On 30 September 1986, the bishopric was suppressed and its territory (again not the title) merged into the Roman Catholic Archdiocese of Sant'Angelo dei Lombardi-Conza-Nusco-Bisaccia, to which see the last Suffragan bishop of Campagna was promoted.
