Adelaide United Football Club is a professional soccer club based in Adelaide, South Australia, Australia. The club participates in the A-League Men under licence from Australian Professional Leagues (APL). The club was founded in 2003 to fill the place vacated by Adelaide City and West Adelaide in the former National Soccer League (NSL), and is now the sole team from the state of South Australia in the A-League. Adelaide United's home ground is Hindmarsh Stadium, also known as Coopers Stadium. Adelaide United holds the record for the largest win in an A-League game. Adelaide defeated North Queensland Fury 8–1 at Hindmarsh Stadium on 21 January 2011. It was also the first time – and, to date, remains the only time – a team had two players score hat-tricks in a single match: one to Marcos Flores and the other to Sergio van Dijk. In 2014, Adelaide United were the winners of the first FFA Cup, beating Perth Glory 1–0 in the final, and in 2016 won their first A-League Grand Final, beating the Western Sydney Wanderers 3–1 with goals from Bruce Kamau, Isaías and Pablo Sanchez. In 2019, Adelaide United became the first team to win three FFA Cup titles after defeating Melbourne City FC in the 2019 FFA Cup Final.

On 13 September former Brisbane Strikers and Newcastle Breakers manager John Kosmina was officially announced as the manager, and within the frame of a few weeks time a team was cobbled together mostly with the remnants of the Adelaide City squad to compete in the clubs inaugural season. On 17 October 2003 Adelaide United won its first NSL match, against Brisbane Strikers 1–0 in front of a crowd in excess of 16,000 people. After an impressive home-and-away season, including a seven-match unbeaten streak during November and December 2003, Adelaide United reached the NSL preliminary final, losing to Perth Glory.
