The Watiwati are an indigenous Australian aboriginal people traditionally living on both sides of the Murray River, from Victoria to New South Wales.
The tribe's name comes from a reduplication the word for 'no' (wati), typical of tribal names in this area.
The Watiwati's lands enclosed some 2,000 sq. miles of territory north and south of the Murray River and Swan Hill. It reached northwards towards Moolpa, N.S.W. To the west its boundary lay at Piangil in Victoria. To the east were the related Wemba-Wemba, north east the Nari-Nari, north northwest the Muthi Muthi, and to their west the Tatitati.
The Watiwati were formed of several clans, one horde called the Dacournditch was located in the area between Tyntynder and Swan Hill.
