The Wiyabal (also Widjabal, possibly from confusion of the letter ⟨j⟩ in the older spelling Wijabal) are an indigenous Australian people of the state of New South Wales.
Norman Tindale assigned the Widyabal about 600 square miles (1,600 km2) of territory on the Upper Richmond River, running south from Kyogle to the area in the vicinity of Casino, with their eastern limits at Dunoon.[1]
