ФК Гисен

Predecessor club Sportclub Teutonia Watzenborn-Steinberg was formed on 1 November 1927. For much of its history this club played in local amateur leagues.

From the mid-2000s, the club experienced a rise through the league system, reaching the tier five Landesliga Hessen-Mitte in 2006 after a runners-up finish in the Bezirksoberliga Gießen/Marburg. Teutonia played at this level for two seasons before being relegated again in 2008. It returned to what had now been renamed the Gruppenliga Gießen/Marburg, where it played for the next three seasons. A league championship in 2011 took it back up to the Verbandsliga Hessen-Mitte, the former Landesliga. It played at Verbandsliga level for the next four seasons before winning the league in 2015 and earning promotion to the Hessenliga for the first time. Winning the league in 2015–16 Teutonia earned another promotion, now to the Regionalliga Südwest, from which the club was relegated one season later.

Teutonia was renamed FC Gießen on 1 July 2018 after acquiring VfB Gießen's football department. VfB announced its closure earlier in March. FC won another Hessenliga championship in 2019, promoting them to the Regionalliga again.
