The TSG Backnang Fussball is a German association football club from the city of Backnang, Baden-Wurttemberg. The club's most notable time was between 1965 and 1976, when it reached as far as Germany's second division for one season.
The club is one of four legally independent entities of the mother club TSG Backnang 1846.
The TSG Backnang was formed on 9 May 1846 as a gymnastics club.
Independently from this club, the FV Backnang formed in 1919 as a football club. It existed as such until the end of the Second World War, when the occupation authorities banned all pre-war sport associations and new ones had to be formed. In Backnang, the Sportvereinigung Backnang was formed, which included a number of pre-war associations, including the footballers. Eventually, the club returned to the original name of the gymnastics club, TSG.
The club did not break through to the higher reaches of German football until 1965, when it earned promotion to the tier-three Amateurliga Nordwurttemberg, where it finished fifth in its first season. The year after, the TSG came second in the league, behind the VfB Stuttgart Amateure, the second team of VfB which was not entitled to promotion to the professional Regionalliga Sud. It was therefore TSG Backnang who took their place in the promotion round, where the team finished first on equal points with the Offenburger FV. In a promotion decider, TSG won 1–0 and earned promotion to the second division.
On 21 November 1967, the club separated into four independent departments, one of them the football department. The reason for this was the promotion of the football team to the Regionalliga, a professional league, which had financial and legal implications for the club that the other departments did not want to carry.TSG only lasted for one season on the professional level, finishing second-last and being relegated back to the Amateurliga again. It came third in its first seaso
