The Transfiguration (Ratnaya) Church (Russian: Преображенская (Ратная) церковь) ― one of the architectural landmarks of the stanitsa of Starocherkasskaya, Rostov Oblast, Russia.

It was constructed on the site of the burnt wooden Church of St. Elijah by the same Moscow masters that built the bell tower of the Resurrection Cathedral.

The second name of the church ― Ratnaya, is linked to Ratny tract, which had long been a place of Cossack armies' assemble.

According to historical sources it is known that in 1673 in the hills just north to Cherkassk there was built a town with a population of about 6,000 people.

The reason for establishment of the settlement was the alliance of Don Cossacks and Russia in their fight against the Turks in Azov.
