Club Deportivo Acero (often shortened to CDA or CD Acero, 'Steel Sporting Club' in Spanish) is a Spanish football team based in Puerto de Sagunto (an urban nucleus in Sagunto), in the Valencian Community, Spain.

Founded in 1919 it plays in Lliga Comunitat – North, holding home games at Estadio El Fornàs, which has a capacity of 4,500 spectators.

[4][5] In the early 1920s the club began to play against such popular teams, like Valencia CF or Levante UD, thus developing in a more professional way.

[6] After the Spanish Civil War, the use of foreign idioms was forbidden, so the football team was renamed to Club Deportivo Acero.
