Crna River (Bosnian: Crna rijeka / Црна ријека, "Black River") is a right-hand tributary of the Željeznica, which is a tributary of the Bosna River, in Bosnia, Bosnia and Herzegovina.^[1] It springs between the slopes of Jahorina and Trebević. It arises from two streams: Duboki Creek (Duboki potok / Дубоки поток, "Deep Creek") and an unnamed one, both at an elevation of around 1320 m.^[2]

The water of the river is very clean, so that its utilization is planned in order to supply Sarajevo with drinking water by constructing a dam and a plant and connection to the water supply network.^[3]
