Saint Gregory Church, Armenian church in Nyugdi, Dagestan, Russia

Saint Gregory Church is an Armenian church in Nyugdi, 37 km from Derbent. It measures 17 m long, 12 m wide and about 18 m high with its dome. Each wall has recesses shaped like triangular prisms ending in five diverging lines, and cross-shaped openings pierce the walls beneath the roof.

A chapel stood here by 1850, when Archbishop Sargis Jalalyants visited and described a small chapel with a square tomb inside. In 1916 the Vanetsyants brothers, Grigor and Lazar Petrosovich, funded the present church, built on the site of Saint Grigoris's martyrdom. Under Soviet rule it was recognized as a historical monument but the interior fell into neglect; restoration since the 2000s was long led by Viktor Danilyan (1951–2019).

The church is Armenian Apostolic, not Orthodox. Pilgrims from Dagestan, southern Russia and elsewhere gather on the penultimate Sunday of August to venerate Saint Grigoris. A stone in the chapel bears an 1879 inscription by Yelizaveta Kochkachyants, who restored the church in memory of herself and her family.

The church is located in Nyugdi and visitors can find it by asking locals for directions. Dress respectfully when visiting, as it remains an active place of worship.

The chapel that preceded the church was measured in 1857 by the Dagestani ethnographer Rostom-bek Erzinkyan: 18 feet long, 10 wide and 20 high, with a small pointed dome topped by an iron cross. A stone inscribed by Yelizaveta Kochkachyants in 1879, recording her restoration of the church, was found in modern times and is kept in the chapel.
