The Archdiocese of Gaeta (Latin: Archidioecesis Caietana) is a Roman Catholic ecclesiastical territory in southern Italy, with its episcopal see in the city of Gaeta, in the Lazio region. The diocese is suffragan of the Archdiocese of Rome.
It dates from 846, when Constantine, Bishop of Formiæ, fled there and established his residence. The see of Formia, abandoned since the end of the sixth century, was thereafter united to diocese of Minturno (Minturnæ). In or soon after 999 Bishop Bernard annexed the see of Traetto.
In 1818 Pius VII merged the diocese of Gaeta with the very ancient see of Fondi. Once a suffragan of the archdiocese of Capua, the diocese was subsequently exempted (i.e. directly subjected to the Pope).
On December 31, 1848, Pius IX raised it to archiepiscopal rank, but without suffragans.
Among its bishops of note were: Francesco Patrizio (1460), friend of Pius II, author of a work in nine books, De Regno et De Institutione Regis, dedicated to Alfonso, Duke of Calabria; and Tommaso de Vio, better known as the famous Thomas Cajetan, a Dominican theologian and Papal diplomat.
The current archbishop is monsignor Pier Luigi Mazzoni.
