Panagia Ekatontapyliani (also known as the Church of 100 Doors) is a historic Byzantine church complex in Parikia town, on the island of Paros in Greece. The church complex contains a main chapel surrounded by two more chapels and a baptistery with a cruciform font.
The origin of the church's name is obscure, as it does not have one hundred doors, or gates. One theory suggests that it is a corruption of the name "Katapoliani", i.e. "the Downtown Church", as it lies by the sea in the lower part of the town of Parikia.
