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.
Members of these communities in Syria and the Hatay province of Turkey (formerly part of Northern Syria), still call themselves Rûm which means "Eastern Roman" or "Asian Greek" in Arabic, both referring to the i.e. Byzantine inheritance, and indeed they follow its central Greek language version of the Constantinian or Byzantine Rite.
In that particular context, the term "Rûm" is used in preference to "Yāwāni" or "Ionani" which means "European-" or Ionian in Biblical Hebrew and Classical Arabic.
Members of these communities also call themselves "Melkites", which literally means "monarchists" or "supporters of the emperor" in Semitic languages (a reference to their ancient allegiance to Macedonian and Roman imperial rule), but, in the modern era, the term tends to be more commonly used by followers of the Greek Catholic Church of Antioch.
