The team was established in 1903 as the football department of gymnastics club Männerturnvereins Kempten. In 1907 the parent association merged with two other local gymnastics clubs to form Turnverein 1856 Kempten and on 21 September 1908 the footballers went their own way as an independent side known as Fußball Club Kempten. The footballers briefly re-joined TV in 1923, but resumed their independence two years later. Following World War IIFC Kempten played in the Amateurliga Bayern-Süd between 1957 and 1963 where they earned mid-table results. As a result of league restructuring in 1963 they slipped to fourth-tier play in the Landesliga Bayern-Süd. Over the next several decades Kempten played as an unremarked side in fourth- and fifth-tier competition. In 1999 the club emerged as the champions of the Landesliga Süd and won promotion to the Bayernliga for a two season long turn. They won their way back to the Bayernliga in 2005, finishing second in the Landesliga, and were immediately relegated, but have returned for the 2007–08 campaign, when a last place finish in the Bayernliga meant relegation once more. In 2008–09, the club declined further, suffering relegation to the Bezirksoberliga, followed by relegation to the Bezirksliga in 2010. The team dropped to a new low for the 2011–12 season with its relegation to the Kreisliga Schwaben-Süd after a loss in the relegation play-off. They had to stay at this level for only one season before a Kreisliga championship took it back up a level, back to the Bezirksliga, from where it was relegated again straight away. It took out another Kreisliga championship in 2015 and returned to the Bezirksliga but was yet again relegated after just one season. FC Kempten plays its homematches in the Illerstadion, opened on 15 August 1963. After renovations in 2000 the facility has a capacity of 9,000 spectators.

In the Schwaben Cup however, Kottern gained the upper hand, defeating the FC 6–5 on penalties after a 2–2 draw after normal time.
