Church of Saint Nicholas in Svir, Catholic church building in Svir, Belarus.

The Church of Saint Nicholas is a stone building with two towers framing the main facade and a distinctive shaped pediment at its peak. The interior follows a three-nave cross-basilica structure that organizes the space for worship and prayer.

A first stone church was begun in 1644 under Fabian Koziełł and his wife Katarzyna Niewiadomska, and consecrated in 1653 by the parish priest Kasper Jasiński. It was destroyed in the Russo-Polish War of 1654–1667 and reconsecrated to Saint Nicholas in 1671. The present church was rebuilt in 1903–1908; only the lower part of the bell tower and the semicircular apse survive from the 17th-century building.

The parish belongs to the Budslau Deanery of the Minsk-Mogilev Archdiocese. One of the church bells was saved when three others were sold for scrap in 1985 and is now displayed near the church. The building is listed in the State Register of Historical and Cultural Values of Belarus under code 612Г000454.

The church stands in Svir, Minsk Region. It was closed by Soviet authorities on 4 March 1961 and later used by a branch of the Smorgon factory from 1981. One of its bells, saved when three were sold for scrap in 1985, is displayed near the building.

The 1903–1908 rebuilding kept two elements of the 17th-century church: the lower part of the bell tower and the semicircular apse, now a chapel under a hemispherical dome. Three bells were sold for scrap in 1985, but the parish saved one, displayed near the church.
