CD Castellón Logo

Football first appeared in the town in 1911 and, after a period of time under the consecutive denominations "Deportivo", "Castalia", "Gimnástico", "Cultural" and "Cervantes", Club Deportivo Castellón was founded on 22 July 1922.

The club featured periodically in the top flight, finishing fifth in 1972–73 and adding a Cup final appearance with a team featuring Vicente del Bosque, who later moved to Real Madrid, serving the club as both a player and coach.

On 29 August 1991, in an extraordinary assembly, the conversion of the club to S.A.D was approved. The first team had just relegated into division two, and would drop another level to the third three years later, in a spell which would last more than one decade.

In the 2004–05 season, Castellón finished fourth in Segunda B, eventually winning its promotion playoffs (both matches) and achieving a return to the silver category. The club's stint in the division would last five years, as relegation would befall in 2009–10, with the Valencian Community outfit ranking last, 13 points behind the following team.

On 18 July 2011, due to the team not paying its players, Castellón was excluded from the third division, being relegated to the fourth.
