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. It was one of the most successful seasons in the club's history as they clinched the Treble by winning La Liga, Copa del Rey and the UEFA Champions League. By doing so, the Catalans became the first European team to twice win the domestic double as well as the highest continental tournament, after winning their first treble in the 2008–09 season. Barcelona's success was majorly down to their formidable forward trio composed of Lionel Messi, Neymar and summer signing Luis Suárez, who scored an unprecedented total of 122 goals in all competitions to become the trio with most goals in Spanish football history.

At the end of the 2013–14 FC Barcelona season, goalkeepers José Manuel Pinto and Víctor Valdés expired contracts were not renewed. Barcelona quickly signed Marc-André ter Stegen from Bundesliga club Borussia Mönchengladbach, and Claudio Bravo from fellow La Liga outfit Real Sociedad. On 15 May, long-time captain Carles Puyol announced his retirement from football after a 15-year career on the first team. Puyol was subsequently named Assistant to Sports Management under Director of football Andoni Zubizarreta. On 19 May, Luis Enrique was named the new manager after it was announced that Gerardo Martino would step down at the end of the season. Enrique returns to Barça after being the B Team manager from 2008 to 2011.
