Malarndirri Barbara Anne McCarthy (born 19 April 1970) is an Australian politician and former journalist who has been a Senator for the Northern Territory since 2016.
She is a member of the Labor Party, and previously served in the Northern Territory Legislative Assembly from 2005 to 2012.
McCarthy was born in Katherine, Northern Territory, and grew up with her mother's family in Borroloola, on the McArthur River.
She began her education in Alice Springs before moving to Sydney to board at St Scholastica's College.
Prior to entering politics, McCarthy worked as a journalist and presenter for ABC News and Current Affairs.
She was known as Barbara McCarthy until 2007, when she adopted her current name to honour her deceased mother.
In 2005, McCarthy was elected to the NT Legislative Assembly for the division of Arnhem.
She was re-elected unopposed in 2008, and was subsequently appointed to the ministry by Paul Henderson.
She held a number of portfolios over the following four years, but lost her seat in Labor's landslide defeat at the 2012 election.
McCarthy subsequently returned to the media as a presenter for NITV and SBS News.
She re-entered politics as Labor's lead Senate candidate in the Northern Territory at the 2016 federal election.
