The Bushman's River () 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. It feeds the Wagendrift Dam and then flows past the town of Estcourt to join the Tugela River near the town of Weenen.
