بطريركية أنطاكية وسائر المشرق للروم الأرثوذكس
Eastern Orthodoxy in Syria represents Christians in Syria who are adherents of the Eastern Orthodox Church. The Eastern Orthodox and 'Greek' Catholic (Arabic: المسيحية الشرقية في سوريا) tradition is represented in Syria by two distinct albeit historically and culturally related Byzantine communities: the Greek Orthodox Church of Antioch, the largest and oldest Christian community in the country, closely followed by the Melkite Greek Catholic Church, itself a Uniate offshoot of the Greek Orthodox Church of Antioch.
