The Yindjilandji are an Indigenous Australian people of the Northern Territory.
The Yindjilandji language is usually grouped as one of the Ngarna languages, and considered a southern variety, and either a dialect of Wagawa if not an independent language.
In Norman Tindale's guesstimate, the Yindjilandji ranged over roughly 8,200 square miles (21,000 km2) of tribal land. They were a Barkly Tableland people, occupying the area about Buchanan Creek and Ranken River, with a western limits toward Dalmore and Alroy Downs. Eastwards their terrain extended over the border with Queensland close to the headwaters of the Gregory River and Lawn Hill Creek.
