Church of Saint Nicholas in Pastavy, Eastern Orthodox church in Pastavy, Belarus.

The Church of Saint Nicholas is an Eastern Orthodox building in Pastavy featuring Russian Revival architectural elements. The structure showcases brick walls with ornamental details, decorative facades, and distinctive onion domes that crown the main form.

A wooden parish church founded in 1522 by Jan Zenowicz, marshal of Oszmiana, stood on this site; it burned around 1660 during the Polish-Russian war and was rebuilt in 1760 by the founder's descendants. After the January Uprising, the tsarist authorities dismantled that church. The present brick church was built in 1891–1893 and consecrated in May 1894.

The parish belongs to the Postavy deanery of the Polotsk and Glubokoye eparchy of the Belarusian Exarchate of the Moscow Patriarchate. The church is consecrated to Saint Nicholas the Wonderworker, and its single-tier gilded iconostasis, with onion-shaped cupolas at the centre and sides, is treated in the Neo-Russian style. Icons from the former dismantled iconostasis are kept as works of art, including "Forefather Abraham" (1866), "The Last Supper" (19th–20th centuries), and images of the apostles and archangels.

The church stands in Pastavy, in the Vitebsk region, and belongs to the Polotsk and Hlybokaye eparchy of the Belarusian Exarchate. The building is entered through a porch topped by a small cupola, and the main prayer hall lies beyond a rectangular refectory. The interior floor is laid with ceramic tiles.

The church was consecrated in May 1894, but its predecessor on the site was a wooden parish church founded in 1522 by Jan Zenowicz, marshal of Oszmiana. That church burned around 1660 during the Polish-Russian war and was rebuilt in 1760 by the founder's descendants. The present brick church was built in 1891–1893.
