The Flying Foam Massacre was a massacre of Aboriginal people around Flying Foam Passage on Murujuga (Burrup Peninsula) in Western Australia by colonial settlers. Comprising a series of atrocities between February and May 1868, the massacre was in retaliation to the killing of a police officer, a police assistant, and a local workman. Collectively the atrocities resulted in the deaths of an unknown number of Jaburara (or Yaburrara, Yapurarra) people, but with estimates ranging from 15 to 150 dead men, women and children.
