The club was founded on 6 September 1949 by a group of young enthusiasts at a bar, they named it "Juventud Unida". After that, the club took part in several competitions in General Sarmiento, where they won many titles. In the 1950s Juventud Unida increased its number of members so the club added new sections such as basketball, boxing, volleyball, and bocce.

In 1957 Juventud Unida affiliated to the Argentine Football Association (AFA). That same year the club inaugurated its stadium located on Sarmiento and Azcuénaga in San Miguel. It was originally named "Franco Muggeri" to honor a former president of the club, then renamed "Néstor Begni". However, the stadium's name was changed again in 2014 to "Ciudad de San Miguel". The stadium has a capacity for about 3,000 people.

In 1992 the club promoted to Primera C via "Torneo Reducido", where it remained two seasons but it was relegated in the 1993–94 season. In 1997–98 the club won its first official title promoting to the upper division.^[]

After some seasons with poor performances, Juventud Unida won another "Torneo Reducido" in 2014 which allowed them to promote to Primera C, although the team would be relegated in 2016.^[]
