The Archdiocese of Pesaro (Latin: Archidioecesis Pisaurensis) is a Latin diocese of the Catholic Church in central Italy.

Its see at Pesaro was elevated to the status of metropolitan archiepiscopal see in 2000.

Its suffragans are the Diocese of Fano-Fossombrone-Cagli-Pergola and the Archdiocese of Urbino-Urbania-Sant'Angelo in Vado.

[1] The first bishop, Florentius, is said to have governed this see in the middle of the second century, while the bishop, Decentius, according to tradition, suffered martyrdom under Diocletian.

Bishop Heradianus was at the Council of Sardica in 343.
