Original Nike Pre-Match football shirt FC Barcelona 2014/15

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.

The season was one of the most successful ones in the club's history, as Barcelona clinched its second continental treble after winning La Liga, the Copa del Rey and the UEFA Champions League. The league title was won in a closely fought title race with Real Madrid, while the Copa victory was achieved with a brilliant 3–1 victory over Athletic Bilbao at Camp Nou in the final. In the Champions League, Barcelona overcame Bayern Munich (3–0 home, 2–3 away) to set up the final against Juventus in Berlin, where Barça triumphed 3–1. Barcelona's success may be in large part attributed to their formidable attacking trio composed of Lionel Messi, Neymar, and summer signing Luis Suárez, who scored a record 122 goals in all competitions to become the trio with most goals in a single season in Spanish football history.

The season was the first since 1998–99 without former captain Carles Puyol, who retired at the end of last season, 2001–02, and 2006–07 without goalkeepers Víctor Valdés and José Manuel Pinto. Valdés joined Manchester United in January 2015; whereas Pinto announced his retirement.
