Wathaurong, also called the Wathaurung and Wadawurrung, are an Indigenous Australian tribe living in the area near Melbourne, Geelong and the Bellarine Peninsula.

They are part of the Kulin alliance.

The Wathaurung language is spoken by twenty-five clans south of the Werribee River and the Bellarine Peninsula to Streatham.

They are sometimes referred to by Europeans as the Barrabool people.

The area they inhabit has been occupied for several thousand years, with one hundred and forty archaeological sites having been found in the region, indicating significant activity over that period.

The Wathaurung Aboriginal Corporation, a Registered Aboriginal Party since May 21, 2009, represents the traditional owners for the Geelong and Ballarat areas, though there is considerable internal disagreement between the two regional groupings, which regard themselves as heirs to culturally and linguistic distinct groups.

The Wathaurong Aboriginal Co-operative, based in Geelong, also has a role in managing Wathaurong Cultural Heritage, for example through its ownership of the Wurdi Youang Aboriginal stone arrangement at Mount Rothwell.
