The Tuchenitsa (Bulgarian: Тученица), also known as the Plevenska Bara or Barata in its lower course, is a 35 km-long river in northern Bulgaria, a right tributary of the river Vit, itself a right tributary of the Danube.

[1] The Tuchenitsa takes its source in the Slatinski Venets Height of the Danubian Plain at an altitude of 359 m, some 1.7 km north of the village of Slatina.

It flows north, gradually bending to the northwest, then turns west and northwest downstream of the village of Tuchenitsa, crossing the Pleven Heights.

Between the village and city of Pleven the river forms a beautiful karst gorge, part of the Kaylaka park and protected area.

The Tuchenitsa flows into the Vit at an altitude of 52 m at the village of Opanets.
