The Botunya (Bulgarian: Ботуня) is a river in northwestern Bulgaria, a right tributary of the Ogosta, itself a right tributary of the Danube. With a length of 69 km, it is the Ogosta's second largest tributary after the Skat. The river takes its source under the name Stara reka at an altitude of 1,550 m east of the summit of Todorini Kukli (1,785 m) in the western part of the Balkan Mountains. It flows north in a deep forested valley until the town of Varshets and then crosses the Varshets Valley in direction northeast. The river bends northwards at the village of Dolno Ozirovo and downstream of Stoyanovo it again turns to the northeast, forming a wide valley covered with croplands. It enters Vratsa Province and turns northwest after receiving its largest tributary, the Varteshnitsa. In that section the river valley becomes asymmetrical. The river flows into the Ogosta at an altitude of 100 m about a kilometer northeast of the town of Boychinovtsi. Its drainage basin covers a territory of 732 km2.
