The 2025 Australian Greens leadership election was held on 15 May 2025 to elect the leader of the Australian Greens.
Larissa Waters was elected unopposed to replace Adam Bandt, who resigned the leadership after losing his seat of Melbourne at the 2025 federal election. Mehreen Faruqi was re-elected deputy leader after defeating Dorinda Cox nine votes to three.
The Greens hold an automatic leadership election following every federal election. The leadership is decided by consensus within the party room (or a party room vote if consensus cannot be reached), and all previous Greens leaders have been elected unopposed.
Following the federal election held on 3 May 2025, the Greens conceded defeat in Brisbane and Griffith, but were expected to retain Melbourne on the night of 3 May. Bandt also said he intended to remain Greens leader, "but obviously that's up to my colleagues".
On 7 May 2025, major media outlets projected that Bandt would lose Melbourne to Labor candidate Sarah Witty. He conceded defeat the following day. Tasmanian senator Nick McKim was appointed acting leader and stated that he would not contest the leadership election.
On 14 May 2025 (one day before the leadership vote), news.com.au reported that Faruqi, Hanson-Young and Waters could all three be declared as co-leaders.
Bandt stated prior to the vote that he would not endorse any candidate. The Australian Young Greens formally opposed Hanson-Young becoming leader, but did not make an endorsement.
