Maronite Catholic Eparchy of Byblos (in Latin: Eparchia Bybliensis Maronitarum) is an eparchy of the Maronite Church immediately subject to the Maronite Patriarch of Antioch in Lebanon. In 2013 there were 160,000 baptized. It is currently governed by Eparch Michel Aoun.
The eparchy includes the Byblos District in Lebanon. Its eparchial seat is the city of Byblos, where is located the Saint John Mark Cathedral.
The territory is divided into 68 parishes and in 2013 there were 160,000 Maronite Catholics.
The eparchy of Byblos was erected on June 12, 1673, and its canonical erection was confirmed in the Maronite Synod of Mount Lebanon in 1736. In 1768 it was united to Eparchy of Batroun. In 1848 the seat of the Eparchy Byblos-Batroun became the Maronite Patriarch of Antioch's seat.
On June 9, 1990, it was separated from Batroun and assumed its present name.
