The Australia men's national soccer team represents Australia in international men's soccer. Officially nicknamed the Socceroos, the team is controlled by the governing body for soccer in Australia, Football Australia, which is affiliated with the Asian Football Confederation (AFC) and the regional ASEAN Football Federation (AFF).

The team played its first match in 1922 and originally participated in the Oceania Football Confederation (OFC). In this confederation, Australia won the OFC Nations Cup four times between 1980 and 2004, and dominated many FIFA World Cup qualification campaigns during earlier rounds. The team won 31–0 against American Samoa in World Cup qualification, achieving the world record for the largest victory in a senior international match. Despite this, the team only managed to qualify for the FIFA World Cup twice in 11 attempts while in this confederation, due to Oceania's single qualification berth always leading to an intercontinental playoff, and thus, not guaranteeing straight qualification. The team moved to the AFC in 2006, winning the AFC Asian Cup once in 2015 (as hosts) and finishing runners-up in 2011. By winning this competition, Australia became the only team in the world to have won two different confederation cups. Since moving confederations, the team has also qualified for the World Cup in every attempt, qualifying an additional four times for an overall six qualifications. Australia has made appearances in the World Cup knockout stages twice, having progressed to this stage in 2006 and 2022. Despite being part of the AFF, Australia has not joined the ASEAN Championship due to mutual agreement.

The team additionally represented Australia at the now-defunct FIFA Confederations Cup four times, winning a silver and bronze medal in 1997 and 2001 respectively. Mark Schwarzer has the most caps for Australia, with 109 to his name, while Tim Cahill has the most goals scored, with 50. Australia initially developed a rivalry with New Zealand and a rivalry with Uruguay, and, after joining the AFC, has developed a fierce rivalry with Japan.
