The Stryama (known in Antiquity as Syrmus) is a river in southern Bulgaria, an important left tributary of the Maritsa. It originates in the Balkan Mountains. The river is 110 kilometres in length and is the sixth longest in the Maritsa drainage.
The river takes its source under the name Kameninitsa at an altitude of 2,158 m at the southern foothills of the summit of Vezhenin the central Balkan Mountains. Until the town of Klisura it flows south in a deep valley with a large longitudinal slope. The river then turns east and southeast, enters the Karlovo Valley and crosses its southern reaches in a wide shallow riverbed. Downstream of the town of Banya the Struma turns southwards and forms a 3 km gorge between Sashtinska Sredna Gora to the west and Sarnena Sredna Gora to the east. After leaving the gorge, the Stryama enters the Upper Thracian Plain, where its current is slow, in a wide and shallow riverbed. Near the village of Ivan Vazovo part of the river's waters are diverted artificially into a major irrigation canal, which flows independently into the Maritsa. The river proper flows into the Maritsa at an altitude of 149 m about 2.3 km south of the village of Manole.
The river receives numerous tributaries, the most important being the Byala reka and the Stara reka in its upper course. Its drainage basin covers a territory of 1,394 km2.
