The Hyundai A-League commenced in 2005 and Adelaide United FC quickly emerged as a dominant force in the competition. The Club was crowned inaugural Premiers, and then followed by a Grand Final berth in 2006/07. During the Club's first Hyundai A-League season, Adelaide United set several records. These included the fastest ever goal (Louis Brain - 13 seconds), three top 10 goals of the season (Shengqing Qu) and best away record (8 wins, 1 draw, 2 losses).
Adelaide United’s 2008/09 campaign saw the Reds surface on the international stage, featuring in the 2008 AFC Champions League Final, before competing in the prestigious FIFA Club World Cup in Japan where the Club secured a commendable 5th place and the FIFA Fair Play Award. Adelaide would also finish the domestic season with a second Hyundai A-League Grand Final appearance.
In the 2010/11 season, Adelaide United bounced back from finishing bottom the previous season, playing a free-scoring brand of football, to finish third on the table. However, the Reds suffered a heartbreaking 3-2 home loss to Gold Coast United in the second week of the finals.
The season also saw Adelaide claim its first Johnny Warren medalist in Marcos Flores (awarded to the best player in the league), as well as a first Hyundai A-League Golden Boot winner in striker Sergio van Dijk, who finished with 16 goals at the end of the regular season.
In the 2014/15 season Adelaide ended its silverware drought by lifting the maiden Westfield FFA Cup under Head Coach Josep Gombau, following a 1-0 win over Perth Glory in the final at Coopers Stadium. The Reds subsequently finished third in the regular season, but was knocked out in the semi-finals.
Barcelona legend, Guillermo Amor, was appointed Head Coach of the Club for the 2015/16 season. A difficult start had the Reds winless after the first eight rounds and situated at the bottom of the table. But Adelaide pulled off the unthinkable, which comprised of a 14-match unbeaten streak, to clinch the Premiers’ Plate.
A few weeks later, Adelaide secured an elusive Championship after beating the Western Sydney Wanderers 3-1 in the Hyundai A-League Grand Final in front of a sell-out crowd at Adelaide Oval, to win the double and cap off the Club’s most successful season to date.
In the 2016/17 season, Adelaide experienced a frustrating to finish ninth but almost advanced to the knockout stages of the AFC Champions League.
