The Roman Catholic Archdiocese of Esztergom-Budapest is the primatial seat of the Roman Catholic Church in Hungary and the Metropolitan of one of its four Latin rite ecclesiastical provinces.
The Metropolitan archbishopric retains the title of Primate, which gives this see precedence over all other Hungarian dioceses, including the fellow Metropolitan Archbishops of Eger, Hajdúdorog, Kalocsa–Kecskemét and Veszprém, but the incumbent may be individually outranked if one of them holds a cardinalate. Its current Archbishop is Péter Erdő.
