The Bushman's River (Afrikaans: Boesmansrivier) is an east to north-easterly flowing tributary of the Tugela River, in the KwaZulu-Natal province of South Africa.

It rises in the Drakensberg Mountain range, with its upper catchment in the Giant's Castle Game Reserve, north of the Giant's Castle promontory.

The Wagendrift Dam near Estcourt is its major reservoir.

Several densely populated rural villages, many inhabited by the amaHlubi, are found in the river's upper catchment area.
