Adam Paul Bandt (born 11 March 1972) is an Australian former politician and industrial lawyer who was the leader of the Australian Greens from 2020 to 2025. He previously served as the member of parliament (MP) for the Victorian division of Melbourne from 2010 to 2025 and was the co-deputy leader of the Greens from 2012 to 2015 and 2017 to 2020.
Bandt won his seat in the 2010 federal election, becoming the first member of the Greens elected to the House of Representatives at a federal election, and the second overall after Michael Organ, who was elected at a by-election. Bandt first contested the seat in 2007, narrowly losing to the Labor Party's Lindsay Tanner. Following his success in the 2010 election, Bandt retained the seat in the 2013, 2016, 2019, and 2022 elections. He was elected leader of the Greens following the resignation of Richard Di Natale in February 2020.
Bandt lost his seat of Melbourne to Labor's Sarah Witty at the 2025 Australian federal election following a 4.4% decrease in his primary vote.
