The Perperek is a 44 km long river in southern Bulgaria, a left tributary of the Arda.
The river takes its source under the name Karakush dere at an altitude of 709 m on the southwestern slopes of the Chukata Ridge of the eastern Rhodope Mountains, about one kilometer from the village of Cherna Niva. Until the village of Perperek it flows in southeastern direction in a wide sparsely forested. Downstream from the village the river takes a large bend to the southwest. Shortly before flowing into the Studen Kladenets Reservoir on the Arda at an altitude of 227 m, the river forms a gorge between the elevations of Kartalkaya to the west and Yumrukkaya to the east, which is now almost flooded by the reservoir. Its drainage basin covers a territory of 220 km2.
