Barnaby Thomas Gerard Joyce (born 17 April 1967) is an Australian politician who served as the deputy prime minister of Australia and the leader of the National Party from 2016 to 2018 and from 2021 to 2022. Now a member of One Nation, he has been the member of parliament (MP) for the New South Wales division of New England since 2013. Joyce previously held various ministerial positions in the Abbott, Turnbull, and Morrison governments.

Joyce was born in Tamworth, New South Wales, and graduated from the University of New England. He was elected to the Senate for Queensland at the 2004 federal election, and became the National Party's Senate leader in 2008. At the 2013 election, he transferred to the House of Representatives, winning the rural seat of New England in New South Wales. In 2013, Joyce replaced Nigel Scullion as deputy leader of the National Party. He succeeded Warren Truss as party leader and deputy prime minister in 2016.

During the 2017–18 Australian parliamentary eligibility crisis, Joyce was confirmed to be a dual citizen of New Zealand, which is forbidden for parliamentarians under section 44 of the Constitution of Australia. In October 2017, the High Court of Australia ruled that he had been ineligible to be a candidate for the House of Representatives at the time of the 2016 election. He re-entered parliament in December 2017 after winning the New England by-election. Joyce resigned from the National Party to join One Nation in 2025, holding one of two seats held by the party, the other held by David Farley, who was elected at the 2026 Farrer by-election.
