Church of St. Mary of the Spring (Istanbul)
 The Monastery of the Mother of God at the Spring (full name in Greek: Μονὴ τῆς Θεοτòκου τῆς Πηγῆς pr. Moni tis Theotóku tis Pigis; Turkish name: Balıklı Meryem Ana Rum Manastiri) or simply Zoödochos Pege (Greek: Ζωοδόχος Πηγή Life-giving Spring) is an Eastern Orthodox sanctuary in Istanbul. The present church built in 1835 bears the same dedication as the shrine erected in this place between the end of the fifth and the beginning of the sixth century.
