The 2012–13 season was a drastic reversal of fortune from the 2011–12 season, in which Fiorentina was involved in a relegation battle. The club narrowly missed out on UEFA Champions League football, vying with Milan up until the last week of the season.
Fiorentina made its first foray into the 2013 summer transfer window merely days after the end of the 2012–13 Serie A by announcing the free transfer of Oleksandr Yakovenko on May 22. On May 31, it was announced that Marcos Alonso will be joining the club following the expiration of his contract at Bolton Wanderers. On June 12, Fiorentina announced that Spanish national Joaquín has agreed to sign on from Spanish club Málaga. Shortly after, the club stated that it will retain Juan Cuadrado after purchasing a 50% co-ownership rights from Udinese. On June 18, Fiorentina announced the signing of Gustavo Munúa, a goalkeeper, who transferred from La Liga club Levante. On June 20, Fiorentina and Torino reached an agreement regarding co-ownerships of Alessio Cerci (who will be fully owned by Torino) and Marko Bakić (will be fully owned by Fiorentina) with undisclosed fee.
Jersey kits for the upcoming season were presented in a ceremony on July 3, 2013 with a gray kit replacing the red and white third kit from last season. On July 4, the club announced the signing of Massimo Ambrosini on a free transfer following the expiration of his contract with Milan. On July 9, 2013, Parma announced the signing of Felipe from Fiorentina. The club sold Haris Seferović to Real Sociedad on July 11. The next day on July 12, the club announced the transfer of Mario Gómez from Bayern Munich. On July 18, the club announced the sale of Stevan Jovetić to Manchester City. On July 23, the club announced the signing of Josip Iličić from Palermo.
On August 9, Fiorentina was drawn against Grasshopper Club Zürich for qualification into the group stage of the UEFA Europa League. Despite losing the 2nd leg at home 1–0, Fiorentina advanced to the Europa League group stage based on away goals after winning the leg at Zürich 2–1.

(Head-to-head record is applied for clubs with the same amount of points only once all matches between said clubs have been played) 1Since the 2013–14 Coppa Italia champions Napoli and runners–up Fiorentina qualified for the 2014–15 European football season thus 4th, 5th and 6th in Serie A (barring any failure to receive a "UEFA licence" from the FIGC or a ban from European competition) would qualify for group stage, play-off round and third qualifying round respectively. 2The FIGC rejected the application of Parma for a UEFA license, because Parma had overdue tax debt; their place went to seventh-place Torino, which had a UEFA license. (C) = Champion; (R) = Relegated; (P) = Promoted; (E) = Eliminated; (O) = Play-off winner; (A) = Advances to a further round.
