Florishcheva Poustinia, Eastern Orthodox monastery in Frolishchi, Russia.

Florishcheva Poustinia is an Eastern Orthodox monastery in Frolishchi within Nizhny Novgorod Oblast, featuring several religious buildings including the Uspensky Cathedral and a bell tower. The site comprises various structures arranged together to form a cohesive monastic complex.

Founded in the mid-17th century by the schemamonk Methodius, the monastery was first built by his associate Hilarion, later Metropolitan of Suzdal. The five-domed Dormition Cathedral was laid in 1680 and consecrated on 30 September 1681 by Metropolitan Simon of Smolensk in the presence of Tsar Feodor Alexeyevich. Closed on 1 April 1923, it housed a military chemical unit in Soviet times and was returned to the church in 2005.

The name Florishcheva comes from the Florishcheva Red Mountain where the monastery stands, not from a saint. Processions circle the monastery on 29 June and 15 August (Julian calendar). The gate church is dedicated to the apostles Peter and Paul and to Ephrem the Syrian.

The monastery stands on Florishcheva Red Mountain above the Lukh River in the settlement of Frolishchi, Volodarsk District. Visitors can reach it by road from Nizhny Novgorod; the site is an active men's monastery, so modest dress and respectful behaviour are expected. The restored 49-metre bell tower with its new clock and bells is a useful landmark for orientation.

The monastery stands on a hill called Florishcheva Red Mountain above the Lukh River. In the 18th century Prince Boris Alexeyevich Golitsyn, a companion of Peter the Great and former governor of Kazan, took monastic vows here under the name Bogolep and ended his life in the community.
