Maronite Catholic Eparchy of Baalbek-Deir El Ahmar (in Latin: Eparchia Helipolitana-Rubrimonasteriensis Maronitarum) is an eparchy of the Maronite Church located in Deir El Ahmar, Lebanon.
The territory of the diocese covers 27 percent of the area of Lebanon[1] and encounters the east and north of the Lebanese-Syrian border, to the west it extends to the high mountains and in the south it joins the Zahleh, established in 1990.
Emperor Constantine the Great (around 288-337) had to build a large church there and the work of excavation of its remains began in 1933.
On August 4, 1977 it was united to the Maronite Catholic Eparchy of Zahleh.
Its first elected eparch on August 5, 1990 was Philippe Boutros Chebaya.
