The Minister for Aboriginal Affairs is a position in the Cabinet of Western Australia, first created in 1947 during the McLarty–Watts Ministry.
The current Minister for Aboriginal Affairs is Peter Collier of the Liberal Party, who holds the position as a member of the Barnett Ministry. The minister, who has generally held other portfolios, is responsible for the state government's Department of Aboriginal Affairs (DAA), which exists "to facilitate the development of policy and programs which deliver sustainable economic, environmental and social benefits to Aboriginal communities".
Twenty people have been appointed as Minister for Aboriginal Affairs in Western Australia, with Edgar Lewis's 8 years and 325 days during the Brand–Nalder Ministry the longest period in the position. The position and corresponding department have existed under several different names, including Native Affairs (4 years), Native Welfare (19 years), Aboriginal Affairs (23 years), and Indigenous Affairs (12 years). The current name was adopted after requests from representatives of Western Australia's Aboriginal communities.
