甘加林聯隊

The club was established by the local Canberra Italian community in 1963 under the name Juventus Soccer Club, inspired by the Italian club of the same name. Juventus competed in the ACT Division One and the Federation Cup in their inaugural season. The following year the club won the league, receiving qualification to the Australia Cup. They competed in the 1965 and 1967 Australia Cup, where they failed to progress past the first round.

In 1973, Juventus SC toured New Zealand between 30 September and 7 October. Juventus was one of the first sporting teams from the ACT to tour New Zealand. The club started the tour in Auckland at Newmarket Park with matches against Auckland and Auckland U23s. Juventus lost both matches 1–3 and 0–3 respectively. Juventus' second tour destination took the club to Muir Park in Hamilton to take on Hamilton AFC on 4 October. Juventus and Hamilton drew 1–1 with a goal from M Valeri securing the visitors a draw. 6 October, Juventus continued its tour in the New Zealand capital of Wellington when they faced off against Wellington City at Rongotai College. Juventus repeated its feats in Hamilton and secured a second 1–1 draw of the tour with J Campbell scoring for Juve. Juventus finished its tour on 7 October at English Oval in the city of Christchurch. Juve succumbed to a 2–0 loss at the hands of Christchurch United.

In 1997, Juventus Soccer Club established the Gungahlin Juventus Soccer Club to cater for the growing number of players in the Gungahlin region.

27 September 2002, Gungahlin Juventus expanded junior operations for boys and girls by incorporating a new separate association under the name Gungahlin Junior Soccer Club (ACT). The new association retained the traditional colours and style of the senior Juventus club.

25 January 2005, Juventus acted to align itself with the national naming scheme to attract a broader base of players for both seniors and juniors and changed its name to Gungahlin United Football Club.

In 2006, following the conclusion of the 2006 ACT Premier League season, Capital Football restructured the Premier League and Gungahlin was removed from the top-tier competition.

In 2011, United entered into a partnership agreement with Premier League club, Canberra City SC, to provide a pathway for Gungahlin players to the ACT Premier League for the first time since 2006. Youth teams at Premier League level competed under the name Gungahlin United, while the senior Premier League team competed under the banner of Canberra City. The partnership was ended in 2012.

In 2015, Gungahlin United was granted a National Premier Leagues (NPL) licence by Capital Football to field a team in the now named National Premier League Capital Football (formally ACT Premier League). This included junior and senior teams for both men and women. In the same year, the team won the Federation Cup, thereby qualifying for the round of 32 of the FFA Cup in 2015.

3 May 2015, Gungahlin United won its first ever NPL match with a 3–1 victory over Woden-Weston at Gungahlin Enclosed. Gungahlin overturned a one-goal deficit at half time to secure the win thanks to goals from Stephen Domenici, Shane Murray and Michael John.

20 June 2015, Gungahlin United won its first trophy in its first year of entering the NPL by clinching the 2015 Federation Cup with a 1–0 victory in extra time over Belconnen. Gungahlin was down to 10 men, thanks to a second half red card to Regan Walsh, but Daniel Barac scored the winning goal in extra time to secure the Cup. By winning the Cup, Gungahlin qualified for the 2015 FFA Cup as Capital Football's representative.

5 July 2015, Gunners drew a home match against former NSL winners Sydney Olympic in the round of 32 in the 2015 FFA Cup. Gungahlin were subsequently beaten by Sydney Olympic at Gungahlin Enclosed 0–1 on 4 August 2015. A crowd of 1,603 turned out on the Tuesday night and saw Olympic substitute Michael Gaitatzis score the winning goal in the 82nd minute of the match.

In 2017, GUFC finished fourth in the ACT NPL and qualified for their inaugural finals series since re-introduction to top flight football in the ACT. Gunners defeated Canberra FC 3–0 in the minor semi-final before succumbing to a 0–2 loss to Canberra Olympic in the preliminary final.
