In June 2009, historical town club CD San Fernando - played one full decade in Segunda División - was dissolved due to insurmountable economic problems, being renamed San Fernando Club Deportivo. Another local outfit, Unión Sporting (founded in 2000), had its berth bought by the new organization,[2] which started competing in Primera Andaluza. San Fernando's first game took place on 2 August 2009, against Sevilla Atlético at Bahía Sur, with the hosts winning 2–0. In its first season, 2009-10, San Fernando certified promotion to Tercera División with a 1–8 away victory against CD San Roque in the last regular season game and knocking out CD Utrera in the promotion playoff.[3]
The side first reached Tercera División in the 2010–11 season, finishing in second position in the regular season but being ousted in the playoffs by La Roda CF (two losses, 0–4 on aggregate). Finally the club reached Segunda División B in the next, 2011–2012 season.[4]
San Fernando managed to qualify to the new third division Primera División RFEF in 2021, but suffered relegation in 2024. In 2025, another relegation from Segunda Federación followed, and the club was moved further down to the División de Honor on 15 July of that year, after the club was unable to register the senior side within the Tercera Federación deadline date.[5] On 24 July, the city council confirmed the club's dissolution to be held on 7 August, with a new club named CD San Fernando 1940 to start in Tercera Andaluza.[6]
