Kazansky Monastery, Orthodox monastery in Vyshny Volochyok, Russia.

Kazansky Monastery is an Orthodox monastery in Vyshny Volochyok built on elevated ground with white walls and several domed structures. The complex includes churches, chapels, and various buildings arranged around a central sacred space.

A women's community founded in 1872 with funds from Prince Arseny Putyatin became a monastery in 1881, with nun Dosifeya (Saltykova) as first abbess. By the early 20th century it was the largest women's monastery in the Tver eparchy, with 600 nuns. Closed in 1919 and used by a military unit, it was revived by decree on 29 January 1991.

Pilgrims come to venerate the graves of Blessed Elder Lyubushka, a spiritual daughter of St Seraphim of Vyritsa, and of Schema-nun Maria Matukasova from Optina Pustyn. The monastery follows a skete rule limiting contact with the outside world: only one church is open to outsiders, and only for the Sunday Divine Liturgy.

The monastery is open daily from 7:00 to 20:00. A skete rule limits contact with the outside world: only one church is open to visitors, and only during the Sunday Divine Liturgy. The grounds remain under repair.

The monastery's main relic was a Greek icon of the Virgin without the Christ Child, once a private shrine of Byzantine emperor Andronicus III Palaeologus. It passed through Monemvasia, Patras and the Russian consul Ivan Vlasopulo before Nicholas I received it in 1839; it was moved here on 1 May 1877 and stolen in 1984.
