The Archdiocese of Monaco (Latin: Archidioecesis Monoecensis) is an exempt Latin ecclesiastical territory or archdiocese of the Catholic Church in Monaco, directly subject to the Holy See, not part of any ecclesiastical province.

The archdiocese's mother church and thus seat of its archbishop is the Cathedral of Our Lady of the Immaculate Conception (Saint Nicholas's or Monaco Cathedral). Dominique-Marie David was appointed Archbishop of Monaco by Pope Francis on 21 January 2020.

Pope Clement VII visited in 1532.

It was established as a pre-diocesan jurisdiction on 30 April 1868, as Territorial Abbacy of Saints-Nicholas-et-Benoît, on territory split off from the Diocese of Nice.

It was promoted as the Diocese of Monaco by Pope Leo XIII on 15 March 1887, and was elevated to the rank of an archdiocese by Pope John Paul II on 30 July 1981.
