In July 2015, Cartagena B was created as FC Cartagena's second reserve team, the first being CD Algar. It took the place of dissolved Soho-Medi CF in the Primera Autonómica,[2][3] achieving immediate promotion as second.
In 2016, the club became Cartagena's first reserve team after the agreement with Algar was not renewed.[4] Another promotion followed (now to Tercera División), after CF Lorca Deportiva assured their promotion to Segunda División B.[5]
