The Hungarian (Greek) Catholic Archeparchy of Hajdúdorog (Latin: Archidioecesis Haidudoroghensis) is a Metropolitan Archeparchy (Eastern Catholic Archdiocese) of the Hungarian Greek Catholic Church.

Its Metropolitan archbishop is the head of the Hungarian Greek Catholic Church. The Metropolitanate is a sui iuris Eastern particular Church in full union with the Catholic Church, which uses the Byzantine Rite in Hungarian language, covering the entire area of Hungary.

The archiepiscopal cathedral is located in the city of Hajdúdorog, whereas the seat of the metropolitanate is in Debrecen according to the founding bull.

On 8 June 1912, it was established as Eparchy (Eastern Catholic Diocese) of Hajdúdorog, on territory formerly belonging to the Metropolitanate sui juris of Romanian Catholic Archdiocese of Făgăraş şi Alba Iulia, Diocese of Prešov, Latin Metropolitan Archdiocese of Esztergom (Hungary), Eparchies (dioceses) of Gherla, Armenopoli and Szamos-Ujvár, Mukacheve and Oradea Mare.

According to Austro-Hungarian authorities, a bomb sent by Ilie Cătărău exploded on February 23, 1914 at the palace of the new Diocese of Hajdúdorog; 3 people were killed and over 20 wounded.
