Evangelistria Monastery, Skiathos, Orthodox monastery in Skiathos, Greece.

Evangelistria Monastery is an Orthodox monastery on a hillside in the northern part of the island of Skiathos, Greece. At its center stands a three-domed church with a carved iconostasis, flanked by former monk cells and service buildings arranged around an inner courtyard.

The monastery was founded in 1794 by Kollyvades monks from Mount Athos, who came to Skiathos seeking a place away from Ottoman pressure. A few years later, it became a gathering point for Greeks swearing an oath of independence, which gave the site a role beyond religious life.

The monastery is dedicated to the Annunciation of the Virgin Mary, celebrated on 25 March. Its name "Evangelistria" is a shortened form of Evangelismos tis Theotokou. The museum displays the loom on which the first Greek flag was woven in 1807, along with priests' vestments, 17th-century manuscripts and 18th-century gospels.

Access is by foot from Skiathos town up a steep metalled road or by public minibus from the town bus terminus. Entrance to the monastery is usually free. The monastery is the only active one on Skiathos, served by four resident monks.

The monastery maintains its own vineyards growing Alypiakos, a red Muscat grape variety whose winemaking method is traced back to the 5th century BC. This grape is considered one of the oldest still cultivated in Greece and is rarely found outside the island.
