Holy Trinity Monastery, Cheboksary, Orthodox monastery in Cheboksary, Russia.

The Holy Trinity Monastery stands on the left bank of the Cheboksary Bay, where the Cheboksarka River meets the Volga. Its complex includes the Cathedral of the Life-Giving Trinity, the Church of the Tolyga Mother of God, and the Church of Theodore Stratelates. The grounds also contain a former House of the Peasant, built in 1928 as a hotel in the Art Nouveau and Constructivist styles and incorporated into the monastery in 1995.

Founded in 1566 by decree of Tsar Ivan the Terrible as a missionary monastery to spread Orthodoxy among the Volga peoples, it was burned and plundered in 1609, and its abbot Archimandrite Gelasius was killed. In 1764 it lost its villages and lands and was assigned to the third class; Empress Catherine II visited in 1767. Closed in October 1924, it was returned to the Cheboksary-Chuvash eparchy in 1992, and restoration began in May 1993.

The monastery is a working men's monastery of the Cheboksary diocese; its name in Chuvash is Tasa Troitsa mănastirĕ. The three churches are dedicated to the Holy Trinity, the Tolga Mother of God and Theodore Stratelates. In 2024 six priests from Cameroon, Côte d'Ivoire, the Central African Republic, Gabon, Benin and Burkina Faso came to train here under Archimandrite Vasily (Pasquier), who instructs them in French.

The grounds are open to visitors, and guided tours are available to explain the architecture and religious significance. Dress modestly and walk respectfully, especially during active services when parts of the complex may be reserved for worship.
