Melkite Greek Catholic Archeparchy of Baalbek (in Latin: Archeparchia Heliopolitana Graecorum Melkitarum) is a diocese of the Catholic Church immediately subject to the Patriarchate of Antioch of the Melkites.
The archeparchy includes the northern part of the Bekaa Valley in Lebanon.
Baalbek is an ancient seat, already known in the fourth century by the name of Heliopolis of Phoenicia.
Baalbek was a suffragan of the Melkite Greek Catholic Archeparchy of Damascus until it acquired its autonomy in 1849.
The cathedral with the bishop's palace were built during the episcopate of Germanos Mouakkad; the church was consecrated by Eparch Agapitos Malouf in 1897.
