Datuna Church (Avar: Датуна гьатӀан; Georgian: დათუნას ეკლესია; Russian: Датунский храм) is the only medieval church that survives in modern Dagestan (where most of the population is Muslim). It is situated in the Shamilsky District, about 4 km south of the village of Datuna (which sits on the bank of the Avarian Koisu, one of the region's major rivers).

The basilica's architecture is similar to that of the Kazreti and Achi monasteries. It is thought to have been built by the Georgian Orthodox missionaries at the turn of the 10th and 11th centuries.^[1] It is the only church surviving from the Christian state of Sarir. It is a reminder of the close political and cultural ties between Georgia and Sarir in the Early Middle Ages.^[2]

The church is listed in the Russian cultural heritage register as a landmark of nationwide (federal) importance.^[3]
