The Australian Labor Party (ALP), also commonly known as the Labor Party or simply Labor, is the major centre-left political party in Australia and one of two major parties in Australian politics, along with the centre-right Liberal Party of Australia. The party has been in government since being elected at the 2022 federal election, and with political branches in each state and territory, they currently form government in New South Wales, Queensland, South Australia, Victoria, Western Australia, the Australian Capital Territory, and the Northern Territory. As of 2023, Tasmania is the only state or territory where Labor forms the opposition. It is the oldest continuous political party in Australian history, being established on 8 May 1901 at Parliament House, Melbourne, the meeting place of the first federal Parliament.

The politics of Australia operates under the written Australian Constitution, which sets out Australia as a constitutional monarchy, governed via a parliamentary democracy in the Westminster tradition. Australia is also a federation, where power is divided between the federal government and the states and territories. The monarch, currently King Charles III, is the head of state and is represented locally by the Governor-General of Australia, while the head of government is the Prime Minister of Australia, currently Anthony Albanese.
