History
Founded in 1970 as Unión Deportiva San Juan, the club was renamed Club Municipal de Deportes San Juan in 1985. In 1991, the club achieved a first-ever promotion to Tercera División, playing five consecutive seasons in the division before suffering relegation.
In June 2012, San Juan returned to the fourth tier after San Fernando CD's promotion to Segunda División B.[4] Relegated in 2016, the club suffered another two consecutive relegations in the following two seasons.
