The origins of Deportivo B can be found in 1914, when is Fabril Sociedad Deportiva is born. In 1963, after a merger with Club Deportivo Juvenil, it officially became the reserve team of Deportivo de La Coruña, being thus renamed Fabril Deportivo.[2]
In 1994 the team was again renamed, this time as Deportivo de La Coruña B. It managed to play four consecutive years in the third division in the mid-90s and another two in the following decade, but competed mostly in the lower leagues.
