The Bailgu are an Aboriginal Australian people of the Pilbara region of Western Australia.
Their northern extension ran as far as the Chichester Range scarp the Nullagine River divide.
The eastern border ran to the western headwaters of the Oakover Davis rivers.
[1] According to oral traditions handed down by the Bailgu, before the advent of the whites, they were dislocated from the salt marshs on the Fortescue river by pressure from the Panyjima tribe, which drove them further east.
This narrative appears to be corroborated by the fact that among western tribes they were known as the Mangguldulkara (people of the marshes).
