The Kalnik (Bulgarian: Калник) is a 41 km-long river in northern Bulgaria, a right tributary of the river Vit, itself a right tributary of the Danube.[1]

The Kalnik takes its source from the Tolev Spring at an altitude of 677 m, on the southern foothills of the Mikrene Heights of the fore-Balkan, some 1.5 km north of the village of Borima. Throughout its whole course the river flows westwards with a slight deviation to the north in a wide valley between the Mikrene Heights to the north and the Vasilyovska Mountain to the south. It flows into the Vit at an altitude of 250 m at the Boaza locality, south village of Peshterna.[1]
Its drainage basin covers a territory of 263 km2 or 8.2% of the Vit's total.[1]
The Kalnik has rain, snow and karst spring feed with high water in April–June and low water in July–October. The average annual discharge is 0.96 m3/s.[1]
