Badalona was founded in 1903 as Football Bétulo Club, being renamed FC Badalona five years later. It played 14 seasons in the second division (1934–36, 1939–41, 1947–52, 1963–68), but this was prior to the creation of the intermediate Segunda División B.
As the club was constantly in economical problems, having to battle for the people's preference with basketball side Joventut Badalona, it nearly disappeared in the early 2000s (as the side was on the verge of celebrating 100 years) but, after another merge, this time with Unió de l'Esport Badaloní, resurfaced and changed names to Club de Fútbol Badalona – with the latter preserving its history – eventually making its debut in the (new) third level in 2004.
In January 2015, its home ground since 1936, Camp del Centenari, was demolished and the club was relocated temporarily at Camp de Montigalà until the completion of the new municipal stadium, that will be inaugurated on 29 January 2017. The club finished 7th in Segunda División B, Group 3 in the 2018-19 season. Badalona had a solid performance at home, having lost only 4 of 19 matches at the Estadi Municipal.
