The Australian Aboriginal Flag represents Aboriginal Australians. It is one of the officially proclaimed flags of Australia, by which it has special legal and political status together with the national flag and the Torres Strait Islander Flag, with which it is often flown.

The flag was designed in 1971 by Harold Thomas, an Aboriginal artist who is descended from the Luritja people of Central Australia. Thomas held the intellectual property rights to the flag's design until January 2022, when he transferred the copyright to the Commonwealth government. The flag was designed for the land rights movement and became a symbol of Aboriginal people of Australia.

The flag is horizontally and equally divided into a black region (above) and a red region (below); a yellow disc is superimposed over the centre of the flag. The overall proportions of the flag, as proclaimed, are 2:3; however, the flag is often reproduced in the proportions 1:2 as with the Australian National Flag.
