The village of Ravnogor was established in 1777 and its first name was Koriya (forest). Since the Turks could not convert the inhabitants of the village to Islam, they called them Aksi (bad) and the village Aksi Koriya (bad forest in Turkish). After the Bulgarian liberation in 1878, by a decision of the municipal council, the name was changed to Yasa Koriya (plain forest in Turkish). It was preserved until 1934, when it was transformed into Ravnogor (plain forest in Bulgarian) by a decree of the Council of Ministers.
