Antiochian Greek Christians are an ethnoreligious Eastern Christian group native to the Levant. They are either members of the Greek Orthodox Church of Antioch or the Melkite Greek Catholic Church, and they have ancient roots in what is now Syria, Lebanon, Palestine, Jordan, the southern Turkish province of Hatay, which includes the city of Antakya —one of the holiest cities in Eastern Christianity, and Israel. Many of their descendants now live in the global Near Eastern Christian diaspora. They primarily speak Levantine Arabic, with Maaloula near Damascus being one of the few places where a Western Aramaic dialect is still spoken.

Hatay Province is the southernmost province and metropolitan municipality of Turkey. Its area is 5,524 km2, and its population is 1,686,043 (2022). It is situated mostly outside Anatolia, along the eastern coast of the Levantine Sea. The province borders Syria to its south and east, the Turkish province of Adana to the northwest, Osmaniye to the north, and Gaziantep to the northeast. It is partially in Çukurova, a large fertile plain along Cilicia. Its administrative capital is Antakya, making it one of the three Turkish provinces not named after its administrative capital or any settlement. The second-largest city is İskenderun. Sovereignty over most of the province remains disputed with neighbouring Syria, which claims that the province had a demographic Arab majority, and was separated from itself against the stipulations of the French Mandate of Syria in the years following Syria's occupation by France after World War I.
