Sredna Gora (Ñðåäíà ãîðà) is a mountain range in central Bulgaria, situated south of and parallel to Balkan mountain range (Stara Planina) and extending from the river Iskar to the west and the elbow of Tundzha north of Yambol to the east. Sredna Gora is 285 km long, reaching 50 km at its greatest width. Its highest peak is Golyam Bogdan at 1,604 m (5,262 ft).
The mountain is divided into three parts by the rivers Topolnitsa and Stryama — a western (Zapadna or Ihtimanska Sredna Gora), a central (Sashtinska Sredna Gora) and an eastern part (Sarnena Gora).
The fauna of Sredna Gora is relatively poor compared to other regions of Bulgaria, with typical Central European species being present.
