The 2020 Cygnian Labour Party leadership election was organised by the Cygnian Labour Party to elect its next congressional leader. All registered members of the party were entitled to vote in the election, although unlike in federal or state elections, voting was not compulsory. A combination of caucus votes and membership votes is used to determine the winner, with both being weighted equally. As such, one had to amass at least 78 of the 154 available caucus votes, as well as a majority of membership votes cast. The election for party members took place from 1 June to 30 July 2020 in all twenty-one states, five territories, and among Labour Abroad. The caucus vote was be held on 31 July.
The election was triggered by Chancellor Julia Gillard's January announcement that she would retire at the December 2020 federal election. Immediately after the announcement, Vice Chancellor Tanya Plibersek announced that she would be running for the leadership. This was followed a few days later by Infrastructure Minister Anthony Albanese, and by Defence Minister Richard Marles.
Normally, the election would be held on a single Saturday, when members would assemble for a meeting of their local party branch in the morning and caucus members would vote in the evening. However, due to the ongoing coronavirus pandemic, the Labour Party National Executive announced on 23 March that the 2020 election would be conducted by postal ballot instead, allowing two months for votes to be sent through.
The election resulted in a decisive victory for Albanese, who was formally sworn in as Leader of the Labour Party on 1 August 2020. However, Chancellor Gillard will remain in office until the conclusion of her term on 3 January 2021. On the same ballot, Marles was elected Deputy Leader.
