The 2014–15 season was Futbol Club Barcelona's 115th in existence and the club's 84th consecutive season in the top flight of Spanish football. This was the first of the three seasons under head coach Luis Enrique.

A treble in association football is achieved when a club team wins three trophies in a single season. A continental treble involves winning the club's top-level domestic league competition, main domestic cup competition, and main continental trophy. Although winning a second-tier continental trophy has also been described as a continental treble, it is not as widely accepted. A domestic treble involves winning three national competitions—including the league title, the primary cup competition, and one secondary competition, such as a secondary cup or state-level league.
