Pauline Hanson's One Nation (PHON or ONP), also known as One Nation or One Nation Party, is a political party in Australia. One Nation was founded in 1997, by member of parliament Pauline Hanson and her advisors David Ettridge and David Oldfield.

The party's founding came before the 1996 federal election because of comments she made about Indigenous Australians. Hanson sat as an independent for one year before forming Pauline Hanson's One Nation.
