The Yalarnnga, also known as the Jalanga, are an indigenous Australian people of the state of Queensland.
Yalarnnga is an extinct language, hypothesized to be one of the two Galgadungic languages.
Norman Tindale estimated their territorial range at 11,000 square kilometres (4,200 sq mi), in the area of Wills Creek, going south of Duchess to Fort William. They lived along the Burke and Mort Rivers and to the north of Chatsworth, and in the localities around Noranside and Buckingham Downs.
The lands of the Yalarnnga were first occupied by white settlers in 1877, at which time their numbers were estimated to be around 200 people.
