The 2012–13 season was Futbol Club Barcelona's 114th season in existence and the club's 82nd consecutive season in the top flight of Spanish football. The season marked the managerial debut of Tito Vilanova, who served as Pep Guardiola's longtime assistant. Vilanova assumed management of the club after Guardiola, who had managed Barcelona for the prior four seasons, declined to renew his contract.

Barcelona finished first in La Liga but lost in the semi-finals of both the Copa del Rey and the UEFA Champions League. The club also set a record (later equaled by Real Madrid) by scoring in all 38 La Liga matches in the season.

Season overview

May/June On 29 May, Barcelona announced their first pre-season match to be against Hamburger SV in occasion of the German outfit's 125th anniversary celebration. It will be Tito Vilanova's first match in charge of the first team. The second match will be on 28 July in Tangier, Morocco, versus an all-star starting XI from the Moroccan Football League at the Stade de Tanger. This will be their first appearance in Morocco in 38 years.

On 1 June, Barcelona announced Brazilian defender Henrique will not return to team after both agreed to terminate the player's contract on 30 June. Henrique did not make an appearance with the first team and was on-loan in 2008–09 with German club Bayer Leverkusen, 2009–10, and 2010–11 with Racing de Santander and in 2011–12, with Brazilian club Palmeiras.

On 28 June, Barcelona and Valencia CF reached an agreement on the transfer of left back Jordi Alba for €14 million. The player joined the team after UEFA Euro 2012 and signed a five-year deal.

President Ángel María Villar also confirmed that both Barcelona manager Tito Vilanova and Real Madrid manager José Mourinho will not have to serve their suspensions in the 2012 Supercopa de España for their altercation in last year's edition. Barça's Board Secretary Toni Freixa stated at a press conference that an "aggression can never go unpunished" and "we understand that an aggression on a coach deserves punishment. This measure doesn't make the aggressor innocent but it allows them to believe that they can keep on being aggressive without consequences. It's a bad example for Spanish football that this aggression hasn't been punished."

On 13 July, Barcelona announced that the pre-season match on 28 July would be played against Raja Casablanca instead of Moroccan All-Star XI as previously announced.

On 24 July, Barcelona opened their pre-season with a 2–1 victory over Hamburg at the Imtech Arena. Goals scored by Dani Alves and Gerard Deulofeu to set off a victorious debut for Vilanova.

On 29 August, the RFEF Competition Committee suspended manager Tito Vilanova after he was ejected in the Osasuna match for what the referee deemed as "angrily protesting a play of the match, after he had been warned by the assistant referee."
