The Negovanka () is a 46 km-long river in northern Bulgaria, a right tributary of the Rositsa, itself a left tributary of the river Yantra of the Danube basin. It is the second longest tributary of the Rositsa after the Vidima.
The Negovanka takes its source from a spring at an altitude of 520 m some 1.8 km southeast of the village of Idilevo in the fore-Balkan. The karst spring northwest of Novo Selo is also an important source of water. The river flows north in a deep valley and close to the village of Emen forms the Emen Canyon in Aptian limestones from the Early Cretaceous, which has been declared a natural monument. Downstream of the canyon the Negovanka turns northeast, its valley widens and the river eventually flows into the Rositsa at an altitude of 67 m.
