Darkinjung is an Australian Aboriginal language, the traditional language of the Darkinjung people. While no audio recordings of the language survive, several researchers have compiled wordlists and grammatical descriptions. It has been classified as a language no longer fully spoken and it can be classified as needing a language renewal program. It was spoken adjacent to Dharuk, Wiradhuri, Guringai, Gamilaraay, and Awabakal. The Darkinjung tribe occupied a small part of southeastern Australia inside what is now the New South Wales area. They likely inhabited a considerable tract of land within Hunter, Northumberland, and Cook counties.
