The Archdiocese of Bar (Latin: Archidioecesis Antibarensis; Montenegrin: Барска надбискупија, romanized: Barska nadbiskupija; Albanian: Kryepeshkopata Katolike Romake e Tivarit) is a Latin Church diocese of the Catholic Church in Montenegro. It is centred in the city of Bar (Italian Antivari). It was erected as a diocese in the 9th century and elevated to an archdiocese in 1089. The Archbishopric was by the Pope's decree abolished some time after 1140, until it was restored by the Serbian medieval Nemanjić dynasty in 1199.

The Archbishops regularly bore titles of "Primates of Serbia" (Primas Serviae), implemented as a permanent part of the title by Archbishop Stephen Tegliatti in 1475.

The archdiocese's new cathedral is the Cathedral of Saint Peter the Apostle (consecrated in September 2017) in Bar. Its old Cathedral of the Immaculate Conception is located near Stari Bar. Rrok Gjonlleshaj currently serves as archbishop in the archdiocese.

In 1923, Traboin, Tuzi, Grude, and Klezna were added to the Archbishopric from the Roman Catholic Archdiocese of Shkodër. In 1969, the territory of the municipalities of Plav, Gusinje, and Vojno Selo were added to the Archbishopric from the Roman Catholic Archdiocese of Skopje.

In 1571 when Ottomans captured Antivari the Catholic Church in border area and Roman Catholic Archdiocese of Bar began to collapse and main reasons for this is emigration of indigenous peoples, but also immigration of new ethnic and religious element, brought by the Ottomans. Because of a lack of Catholic priests, entire parishes were converted to Orthodoxy.
