A Registered Native Title Body Corporate (RNTBC) is a corporation nominated by a group of Aboriginal or Torres Strait Islander people for the purposes of native title in Australia, to represent their native title rights and interests, once that group's native title application has been recognised in a Federal Court of Australia determination, and the corporate body registered. The corporation nominated hold and manage (as trustee) or manage (as agent) before native title determination and registration, is called a Prescribed Body Corporate (PBC).
In 2015, there were 144 RNTBCs registered with the Office of the Registrar of Indigenous Corporations (ORIC). PBCs are required to register with ORIC, under the provisions of the Native Title Act 1993. They must have the words "registered native title body corporate" or "RNTBC" in their name, while other Aboriginal and Torres Strait Islander corporations can choose to register under other state or territory associations law, or under the Corporations Act 2001 (Cth).
