Native title is the designation given to the common law doctrine of Aboriginal title in Australia, which is the recognition by Australian law that Indigenous Australians (both Aboriginal Australian and Torres Strait Islander people) have rights and interests to their land that derive from their traditional laws and customs. The concept recognises that in certain cases there was and is a continued beneficial legal interest in land held by Indigenous peoples which survived the acquisition of radical title to the land by the Crown at the time of sovereignty. Native title can co-exist with non-Aboriginal proprietary rights and in some cases different Aboriginal groups can exercise their native title over the same land. The foundational case for native title in Australia was Mabo v Queensland (No 2). One year after the recognition of the legal concept of native title in Mabo, the Keating Government formalised the recognition by legislation with the enactment by the Australian Parliament of the Native Title Act 1993. The Act attempted to clarify the legal position of landholders and the processes to be followed for native title to be claimed, protected and recognised through the courts. The Federal Court of Australia arranges mediation in relation to claims made by Aboriginal and Torres Strait Islander peoples, and hears applications for, and makes, native title determinations. Appeals against these determinations can be made to a full sitting of the Federal Court and then to the High Court of Australia. The National Native Title Tribunal (NNTT), established under the Native Title Act 1993, is a body that applies the "registration test" to all new native title claimant applications, and undertakes future act mediation and arbitral functions. The Attorney-General's Department advises the Australian Government on legal and legal-policy regarding on native title, and assists the Attorney-General to administer the Native Title Act 1993.

The Native Title Act 1993 (NTA) gives recognition that "Aboriginal and Torres Strait Islander people have rights to land, water and sea, including exclusive possession in some cases, but does not provide ownership". It allows for negotiations over land, but does not
