Церковь Великомученика Дмитрия Солунского, Baroque church in Dmitrovsk, Russia.

The Church of Saint Demetrius of Thessaloniki in Dmitrovsk is a Baroque building with a central dome and bell tower. The structure displays characteristic features of Russian Baroque architecture from the early 18th century.

A wooden church stood here from the founding of the village of Dmitrovka in 1711. In 1721 Prince Dimitrie Cantemir laid the stone church, completed in four years and consecrated in 1725 to Saint Demetrius, Constantine the Great and Helena. It became the town's main church in 1802, was looted under Soviet rule, and was reopened on 10 August 1942.

The church was consecrated in 1725 to Saint Demetrius of Thessaloniki, Emperor Constantine I and his mother Helena. Its iconostasis and icons survive as they were at that consecration. From the late 1720s the parish feast on 4 June (22 May) hosted the "Tsari" fair, the oldest in Dmitrovsk and its largest until other churches founded their own.

The church stands at 25 Sotsialisticheskaya Street in the southern part of Dmitrovsk, on the high right bank of the Obshcheritsa River, oriented west to east. It has remained open since its reconsecration on 10 August 1942. Only one tier of the bell tower survives, rebuilt after the 1943 damage.

The iconostasis and icons survive as they were at the church's consecration in 1725, despite later rebuildings. The only surviving metric book of the church, for 1892, is kept in the State Archive of Oryol Oblast. The church is the only surviving and still functioning of Dmitrovsk's eight churches.
