Antiochian Greek Christians, (Arabic: مسيحيو أنطاكية اليونانيون; Greek: Ρωμιοί της Αντιοχείας) also known as Rûm, are a Levantine Arabic-speaking ethnoreligious Eastern Christian group from the Levant region. They are either members of the Greek Orthodox Church of Antioch or the Melkite Greek Catholic Church, and they have ancient roots in the Levant, more specifically, the territories of western Syria, northern and central Lebanon, western Jordan, and the southern Turkish province of Hatay, which includes the city of Antakya (ancient Antioch)—one of the holiest cities in Eastern Christianity. Many of their descendants now live in the global Near Eastern Christian diaspora. With Arabic becoming the lingua franca in the Levant, they primarily speak Levantine.
