El Olivo earned promotion in May 2011 after topping
Segunda División's Group 1 and overcoming
UD Tacuense and
Girona FC in the play-offs, becoming the first team from
Galicia to play in Superliga/Primera since the category's unification in 2001. The team was subsequently relegated as it was second to last in its debut season. On 7 July 2017, despite avoiding the relegation from the
Segunda División, the club was sanctioned and relegated due to an illegal alignment of a player during the whole season. In August 2018, El Olivo announced the dissolution of the football section. ==Season to season==
