The Antonin Maronite Order (known also as Antonins or Mar Chaya Monks) is a monastic order among the Levantine Catholic Maronite Church, which from the beginning has been specifically a monastic Church. The order was founded on August 15, 1700, in the Monastery of Mar Chaya, Lebanon by Maronite Patriarch Gabriel Al Blouzani from Blaouza (1704-1705).
Its name comes from the Arabic Antouniyah (Arabic: الرهبنة الانطونية), Saint Anthony monks. They are also called Mar Chaaya monks (Arabic: رهبان مار شعيا), in reference to the monastery hosting the see of their superior general. It is one of the three Lebanese congregations of Saint Anthony the Great monks alongside the Baladites and Aleppians.
