The Seven Churches of Revelation, also known as the Seven Churches of the Apocalypse and the Seven Churches of Asia, are seven major churches of early Christianity, as mentioned in the New Testament Book of Revelation. All of them are located in Asia Minor, present-day Turkey.

Early Christianity, otherwise called the Early Church or Paleo-Christianity, describes the historical era of the Christian religion up to the First Council of Nicaea in 325. Christianity spread from the Levant, across the Roman Empire, and beyond. Originally, this progression was closely connected to already established Jewish centers in the Holy Land and the Jewish diaspora throughout the Eastern Mediterranean. The first followers of Christianity were Jews who had converted to the faith, i.e. Jewish Christians. Early Christianity contains the Apostolic Age and is followed by, and substantially overlaps with, the Patristic era.
