The Combienbar River is a perennial river of the Bemm River catchment, located in the East Gippsland region of the Australian state of Victoria.

Combienbar River rises below the Three Sisters, in a remote state forestry area east of the Errinundra National Park, and flows generally north by west, then south, then south by west, joined by eight minor tributaries, before reaching its confluence with the Errinundra River to form the Bemm River, near Boulder Flat, northwest of the town of Cann River in the Shire of East Gippsland. The river descends 720 metres (2,360 ft) over its 33-kilometre (21 mi) course.

The Combienbar River sub-catchment area is managed by the East Gippsland Catchment Management Authority.
