The Portaulun were an indigenous Australian people of South Australia.
The Portaulun's territory was estimated by Norman Tindale to encompass roughly 300 square miles (780 km2), along the western bank of the Murray River from Wood Hill to Wellington and Pomanda Point. Their westward extension ran to Grote Hill.[1]

The last Portaulun full-blood was David Ngunaiponi, who died in 1967.[1]
