Dochiariou monastery, Orthodox monastery on Mount Athos, Greece

Dochiariou monastery is an Orthodox monastery on Mount Athos featuring stone buildings constructed in traditional Byzantine monastic style. The complex spreads across several levels on the southwestern coast and includes monks' cells, a church, and supporting structures.

Founded by the monk Euthymios, a disciple of Saint Athanasios of Athos, at the end of the 10th or beginning of the 11th century, the monastery is named after his role as dochiaris (cellarer) at the Great Lavra. Euthymios first built a church and skete at Daphni, then moved north and built a church of Saint Nicholas at the present site. The main church was later dedicated to the Archangels after a novice was saved from the sea. Byzantine emperors Michael VII Doukas or Nikephoros III Botaneiates funded renovations, and in the 16th century the monastery was revived after a Turkish raid by a Wallachian voivode.

The name comes from the Greek for "storekeeper", after the founder Euthymios, who served as cellarer of the Great Lavra. The patronal feast of the Archangels is kept on 8 November, and the Gorgoepikoos icon is celebrated on 1 October, a commemoration held here since 1919. The wonderworking icon, painted in the 10th century under Abbot Neophytos, stands in a chapel right of the refectory entrance.

Only male visitors can visit the monastery and must obtain special permits to access Mount Athos peninsula. It helps to check current entry rules in advance and allow time for traveling to and from the site.

The main church contains frescoes painted in 1568 by a Cretan artist that were later added to in the 1780s. These artworks show two distinct artistic periods side by side within the monastery's interior.
