The Gundangara (also spelt Gundungara and Gundungurra) are a clan of Indigenous Australians in south-eastern New South Wales, Australia. Their traditional lands include present day Goulburn and the Southern Highlands.
The ethnonym Gundangara combines lexical elements signifying both 'east' and west'.
The first attempt at a brief description of the Gundangara language was undertaken by R. H. Mathews in 1901. The language itself, now extinct, is classified as a subset of the Yuin-Kuric branch of the Pama-Nyungan language family, and is very close to Ngunnawal.
The Gandangara lived throughout an area covering an estimated 4,100 sq. miles in the south-east region of New South Wales. According to Norman Tindale, their lands encompassed Goulburn and Berrima, running down the Hawkesbury River (Wollondilly) until the vicinity of Camden. This includes the catchments of the Wollondilly and Coxs rivers, and some territory west of the Great Dividing Range.
Their neighbours were the Dharug to their north,Darkinung, Wiradjuri Ngunawal and Thurrawal, (eastwards) peoples.
