The origins of the club are in the establishment in 1920 of the football club Fußballverein Eintracht Allendorf. In 1956, this club merged with Turn- und Sportverein Blau-Weiß Allendorf to form the present day association.
Between 1965 and 1966, TSV played in the Landesliga Hessen/Nord (IV), before becoming part of the Landesliga Hessen/Mitte (IV) in 1967, where they played until being sent down following a 16th-place finish in 1970. The team slipped into lower-level competition before appearing in the Bezirksoberliga Gießen-Marburg Nord (VI) between 1991 and 1998. They won their way back to the Landesliga Hessen/Mitte (V) in 1998 on the strength of a first-place result in the Bezirksoberliga, and ten years later captured a Landesliga title to advance to the Oberliga Hessen (V). Since 2017 they have experienced a series of promotions and relegations between the Hessenliga and the Regionalliga Südwest.
With the introduction of the Regionalligas in 1994 and the 3. Liga in 2008 as the new third tier, below the 2. Bundesliga, all leagues below dropped one tier. Also in 2008, a large number of football leagues in Hesse were renamed, with the Oberliga Hessen becoming the Hessenliga, the Landesliga becoming the Verbandsliga, the Bezirksoberliga becoming the Gruppenliga and the Bezirksliga becoming the Kreisoberliga.
