The Greek Orthodox Church of the Annunciation (Greek: Ορθόδοξος Ναός του Ευαγγελισμού), also known as the Greek Orthodox Church of Saint Gabriel, is an Eastern Orthodox church in Nazareth, Israel. Likely first established in Byzantine-era Palaestina Prima, it was rebuilt during the time of the Crusades, and again in the 18th century under the rule of Zahir al-Umar, the Arab governor of the Galilee.
