2020 Australian Capital Territory general election

The 2020 Australian Capital Territory general election was held between 28 September and 17 October 2020 to elect all 25 members of the unicameral ACT Legislative Assembly.

The incumbent Labor-Greens coalition government, led by Chief Minister Andrew Barr, defeated the opposition Liberal Party. On the night of the election Barr claimed victory and confirmed Labor would again seek to enter into an arrangement with the Greens to form government, whilst Liberal leader Alistair Coe conceded the election and acknowledged the party would retain opposition status in the Assembly. The result meant that the Labor Party, which had been in office for 19 years at this election, won a sixth consecutive term of government in the Territory. Despite the victory, Labor's representation in the Assembly dropped to 10 seats, whilst the Liberals also suffered a decline in their vote and fell to 9 seats. The Greens retained the balance of power and picked up the seats lost by the two larger parties to claim 6 seats, its largest representation in the Assembly in the party's history. Following the election, Labor and the Greens signed an agreement on 2 November to support a Labor-led Government with three ministers from the Greens.

The election was conducted by the ACT Electoral Commission, using the proportional Hare-Clark system. At the preliminary close of rolls, there were 302,630 people enrolled to vote representing a 6% increase on the 2016 election. Legislative changes in the Australian Capital Territory allowed for people to enrol during polling, with a further 3,370 electors enrolling before polling finished on 17 October.
