Crna Reka (region)

Crna Reka (Serbian Cyrillic: Црна Река) or Crnorečje (Црноречје), meaning "Black River", is a region in eastern Serbia, comprising the historical Crna Reka nahiya (Црноречка нахија) and Crna Reka okrug, delineated by the mountains of Samanjac and Kučaj in the west and northwest, Crni Vrh, Veliki Krš, Stol and Deli Jovan in the north, Stara Planina in the east and Tupižnica and Rtanj in the south. Today, the toponym Crnorečje is more often used for the upper- and mid-course of the Crni Timok river. It includes the cities of Bor, Zaječar, and the municipality of Boljevac.
