Odrin-Nikolaevsky Monastery, Eastern Orthodox monastery in Odrina village, Bryansk Oblast, Russia

Odrin-Nikolaevsky Monastery is an Orthodox convent in Odrina village, Karachevsky District, Bryansk Oblast. Of the pre-revolutionary complex, only two mid-19th-century buildings survive: the two-storey abbot's house with columns and the 1856 brethren's building with a church of Saints Peter, Jonah and Alexis. The main relic is the original wonder-working icon of the Mother of God "The Surety of Sinners", glorified here in 1843.

The monastery arose in the 13th or 14th century at the site where, according to tradition, an icon of Saint Nicholas appeared by the Odrina River; three brothers from Bryansk carried the image to their city, where a plague ceased, but after the church burned the icon returned to a pine tree by the Odrina, prompting a wooden church that began the community. A 1352 charter of the nun Eupraxia, daughter of Grand Duke Olgerd of Lithuania, granted it land. It was devastated in the Time of Troubles and again in 1720, when attackers burned it and tortured the elder Barnabas to death. In 1843 the wonder-working icon of the Mother of God "Surety of Sinners" was glorified there. Closed in 1924, it was revived in 1995 as a women's monastery.

The monastery is dedicated to Saint Nicholas of Myra, and his presence is felt throughout the site in icons, dedications, and the name of the spring on the grounds. Pilgrims often come to collect water from that spring, which they regard as holy.

The monastery sits at the edge of Odrina village and is reached by following local roads through the settlement. Modest clothing is expected, as the site is still used for worship every day.

A spring on the monastery grounds is dedicated to Saint Nicholas the Wonderworker and draws pilgrims who visit outside of any service. Some visitors come specifically for the water, which they carry home in containers.
