Trinity church in Ozerki, Eastern Orthodox church in Vyborgsky District, Russia

Trinity Church in Ozerki was a lost Orthodox church in the Ozerki area of Saint Petersburg, built 1900–1904 to designs by civil engineer A. S. Tikhanov, with construction supervised by architect P. P. Trifanov. It held about 500 people, stood roughly 30 m tall, and had a two-tier gilded iconostasis in the Old Russian style made to sketches by D. V. Dudakov. Its bell tower had ten bells donated by the Ozerki property owner Tryanichev, the largest weighing 212 poods (3.5 tonnes).

The church was built between 1900 and 1904 to relieve the overcrowded parish of the Church of the Saviour Not Made by Hands in Shuvalovo. A chapel designed by A. I. Nosalevich was laid in 1898; the church project by A. S. Tikhanov was approved in 1900 and built under P. P. Trifanov. It was consecrated on 9 May 1904 by Bishop Antonin of Narva, with Saint John of Kronstadt taking part. Closed in 1938, the building became a warehouse and in 1961 passed to the Baptists.

The church was consecrated on 9 May 1904 in memory of the coronation of the imperial couple, and John of Kronstadt took part in the ceremony. A charitable brotherhood founded in 1909 ran a primary school. The southern part of Bolshaya Ozyornaya Street was renamed Troitskaya after the church.

The church no longer exists as an Orthodox building: it was closed in 1938, turned into a warehouse, and in 1961 handed to the Evangelical Christian Baptists, who in 1980-1982 added a large prayer hall on the site of the dismantled apse. The former church stood near the First Lake, close to Poklonnaya Hill in Ozerki, Vyborgsky District. The southern part of Bolshaya Ozyornaya Street was renamed Troitskaya Street after it.

The church held about 500 people and stood roughly 30 metres tall. Its two-tier gilded iconostasis in the old Russian style was made to sketches by D. V. Dudakov at the expense of churchwarden D. M. Mikhailov, and the Ozerki homeowner Tryanichev gave ten bells, the largest weighing 212 poods (3.5 tonnes).
