Tuman monastery, Orthodox monastery in Golubac, Serbia.

Tuman Monastery (Manastir Tuman) is a Serbian Orthodox monastery in the village of Snegotin, 12 km southeast of Golubac, on the left bank of the Tumanska reka in a forested depression of the Severni Kučaj mountain. Its church, dedicated to the Archangel Gabriel, is built of stone in the Serbian-Byzantine style, with a stone vault and brick roof. The complex also includes a large konak, a small konak and the cave hermitage of Zosimus the Sinaite, about 1 km away.

Construction of the complex began in the late 14th century and was completed before the Battle of Kosovo in 1389. The first written mention comes from the Ottoman census of 1572.

The name Tuman is linked to the archaic Serbian word for fog, though folk tales explain it through Zosimus's words "Tu mani" (leave it). Pilgrims gather for the feast of the Archangel Gabriel and for the relics of Zosimus the Sinaite and Jakov the New, kept in the church nave.

The site is reached by a narrow mountain road that can be difficult for larger vehicles. The resident community of monks welcomes visitors during daylight hours, with modest dress and quiet behavior expected.

In 1936 thirty Russian monks brought valuable items here, including the old Russian icon known as The Theotokos of Kursk. The grounds also hold a small zoo and a fish pond maintained by the community.
