The massacre of Running Waters was the killing of 80 to 100 Arrernte men, women and children of the Southern Aranda language group of Aboriginal Australians by a raiding party of 50 to 60 Matuntara warriors in 1875. The massacre took place at Irbmangkara, a permanent water stretch of the Finke River about 200 kilometres (120 mi) south-west of Alice Springs in the Northern Territory of Australia.
