Yolŋu Matha, meaning the 'Yolŋu tongue', is a linguistic family that includes the languages of the Yolngu, the indigenous people of northeast Arnhem Land in northern Australia. The ŋ in Yolŋu is pronounced as the ng in singing.

The Yolngu or Yolŋu are an aggregation of Aboriginal Australian people inhabiting north-eastern Arnhem Land in the Northern Territory of Australia. Yolngu means "person" in the Yolŋu languages. The terms Murngin, Wulamba, Yalnumata, Murrgin and Yulangor were formerly used by some anthropologists for the Yolngu.
