The Church of Christ Pantocrator (Bulgarian: църква „Христос Пантократор“, tsarkva „Hristos Pantokrator“ or църква „Христос Вседържател“, tsarkva „Hristos Vsedarzhatel“, Byzantine Greek: Ναός Χριστού Παντοκράτωρος) is a medieval Eastern Orthodox church in the eastern Bulgarian town of Nesebar (medieval Mesembria), on the Black Sea coast of Burgas Province. Part of the Ancient Nesebar UNESCO World Heritage Site, the Church of Christ Pantocrator was constructed in the 13th–14th century and is best known for its lavish exterior decoration. The church, today an art gallery, survives largely intact and is among Bulgaria's best preserved churches of the Middle Ages.
