Saint John the Evangelist Church, Smolensk, Eastern Orthodox church in Smolensk, Russia.

The Church of St John the Evangelist stands on a low hill above the Dnieper. It is a single-domed, four-pillared church whose original 1173 brick walls rise on a cobblestone foundation; the vaults, octagon and dome supports were rebuilt in the 18th century. Decorative crosses made of plinth bricks survive on the outer corner pilasters, and the floor is now almost two metres above the original level.

The church was founded under the command of Roman I of Kyiv, connecting it to the early medieval religious architecture of the region. Later it received official designation as a federal cultural heritage site, placing it under Russia's legal protection framework.

The name "na Varyazhkakh" refers to the Varangian quarter where foreign merchants lived; in 1958 archaeologist Daniil Avdusin found, 30 m west of the church, the remains of a 12th-century brick rotunda about 18 m across, the "German" Latin church of the foreign traders, which held one of the two standard weights, the "wax pood". The church was converted into a Catholic church under Polish-Lithuanian rule after 1611, returned to Orthodox use later, closed in 1933 and used as a museum and library, and handed back to the Smolensk eparchy in 1993.

The church stands on a low hill above the Dnieper at Bolshaya Krasnoflotskaya Street 11. The floor inside is almost two metres higher than the original 12th-century level, reached by steps. Restoration has continued since the building was returned to the Smolensk eparchy in 1993, so parts may be closed off.

In 1958, archaeologist Daniil Avdusin found, 30 metres west of the church, the remains of a narrow-brick rotunda about 18 metres across: the 12th-century church of the "German Mother of God", built for foreign merchants, where one of the two standard weights, the "wax pood", was kept.
