The Sinapovska reka is a river in southern Bulgaria, a right tributary of the river Tundzha of the Maritsa drainage, with a length of 50 km.
The river takes its source under the name Golyamata reka at an altitude of 574 m in the small Sakar mountain range. It initially flows in direction northwest and then northeast in a narrow valley. At the village of Dobroselets the river changes direction first to the east and then to the southeast, flowing between the northern slopes of Sakar in the south and the southern slopes of the Manastirski Heights to the north. In this section its valley significantly widens and has an asymmetrical profile with steeper right (southern) slopes. After the village of Sinapovo, it enters the southwestern part of the Elhovo Field. The Sinapovska reka flows into the Tundzha at an altitude of 96 m.
Its drainage basin covers a territory of 871 km2.
