The Yuin–Kuric languages are a group of mainly extinct Australian Aboriginal languages traditionally spoken in the south east of Australia. They belong in the Pama–Nyungan family. These languages are divided into the Yuin, Kuri, and Yora groups, although exact classifications vary between researchers. Yuin–Kuric languages were spoken by the original inhabitants of what are now the cities of Sydney and Canberra.

The Dharug language, also spelt Darug, Dharuk, and other variants, and also known as the Sydney language, Gadigal language, is an Australian Aboriginal language of the Yuin–Kuric group that was traditionally spoken in the region of Sydney, New South Wales, until it became extinct due to effects of colonisation. It is the traditional language of the Dharug people. The Dharug population has greatly diminished since the onset of colonisation. Eora language has sometimes been used to distinguish a coastal dialect from hinterland dialects, but there is no evidence that Aboriginal peoples ever used this term, which simply means "people". Some effort has been put into reviving a reconstructed form of the language.
