The Topchiyska reka is a river in northeastern Bulgaria, a right tributary of the Danube. Its length is 89 km. The Topchiyska reka takes its source from a spring at an altitude of 293 m in the western part of the Ludogorets Plateau. With the exception of its uppermost course, the river flows in a deep valley cut in Aptian limestones. It flows north until the village of Pobit Kamak, then west until Topchii and then north again. West of the town of Kubrat the Topchiyska reka dries up, its valley heading west and until taking a final turn north. At the village of Malko Vranovo it reaches the Pobrezhie Plain, there the river bed is replaced by irrigation and drainage canals. It flows into the Danube in front of the Bulgarian island of Mishka at an altitude of 14 m. Its drainage basin covers a territory of 660 km2.
