Our Lady of Tinos (Greek: Παναγία Ευαγγελίστρια της Τήνου, Panagía Evangelístria tēs Tēnou, lit. "The All-Holy Bringer of Good News", and Μεγαλόχαρη της Τήνου, Megalócharē tēs Tēnou, lit. "She of Great Grace") is the major Marian shrine in Greece. It is located in the town of Tinos on the island of Tinos.
The complex is built around a miraculous icon which according to tradition was found after the Virgin appeared to the nun Pelagia and revealed to her the place where the icon was buried. The icon is widely believed to be the source of numerous miracles. It is by now almost completely encased in silver, gold, and jewels, and is commonly referred to as the "Megalócharē" ("[She of] Great Grace") or simply the "Chárē Tēs" ("Her Grace"). By extension the church is often called the same, and is considered a protectress of seafarers and healer of the infirm.
