The Melkite Greek Catholic Church is the largest Catholic community in Syria and Israel, and the second largest in Lebanon. As of 2014 the Melkite Greek Catholic Church was the largest Christian community in Israel, with roughly 60% of Israeli Christians belonging to the Melkite Greek Catholic Church.

Due to the Christian emigration from the Middle East, São Paulo is now home to the largest Melkite community in the diaspora (estimated around 433,000), followed by Argentina (302,800). Other large Melkite communities can be found in Australia (52,000), Canada (35,000), Venezuela (25,400), the United States (24,000), and other countries. According to figures by the Holy See in 2008, Lebanon is now home to the largest Melkite community in the Middle East (425,000), followed by Syria (234,000). There are more than 80,000 Greek Melkite Catholics in Israel and Palestine, and 27,600 Greek Melkite Catholics in Jordan. The Melkite Greek Catholic Church is by far the largest Catholic church in Israel.
