Aboriginal Protection Board, also known as Aborigines Protection Board, Board for the Protection of Aborigines, Aborigines Welfare Board, and similar names, refers to a number of historical Australian state-run institutions with the function of regulating the lives of Aboriginal Australians. They were also responsible for administering the various half-caste acts where these existed and had a key role in the Stolen Generations. The boards had nearly ultimate control over Aboriginal people's lives.
