Revelation 2 is the second chapter of the Book of Revelation or the Apocalypse of John in the New Testament of the Christian Bible. The book is traditionally attributed to John the Apostle, but the precise identity of the author remains a point of academic debate. This chapter contains messages to churches of Ephesus, Smyrna, Pergamum and Thyatira, four of the seven churches of Asia located in modern-day Turkey, with messages for the other three churches appearing in chapter 3.

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.
