Darkinjung is an extinct Australian Aboriginal language, the traditional language of the Darkinjung people. It was spoken adjacent to Dharuk, Wiradhuri and Awabakal. Since 2003 there has been a movement from the Darkinyung language group to revitalise the language. Where there were gaps in the sparsely populated wordlists, words were taken from lexically similar nearby languages. This led to the publishing of the work: Darkinyung grammar and dictionary: revitalising a language from historical sources.
