Yagan (c. 1795–11 July 1833) was a Noongar warrior who played an important part in early indigenous Australian resistance to European settlement and rule in the area of Perth, Western Australia.
Yagan was the son of Midgigoroo, one of the elders of the tribe who lived in the Perth area. Yagan was blamed for spearing cattle near the Swan River. There were not many cattle in the new colony and food was scarce. Yagan's taking of the settlers animals and food supplies was seen as a very serious crime. After a European was killed, the military started a search for Yagan. He was found after four months and sent to Carnac Island. He escaped after six weeks. One of the soldiers who had got to know him on Carnac Island, compared him to William Wallace.
