A total of 20 teams competed in the league: 17 sides from the 2013–14 season and three promoted from the 2013–14 Serie B campaign.
Cesena, the play-off winner, returned to the top level after two years in Serie B.
The pre-season saw two ownership changes: Cagliari was sold from Massimo Cellino to Milanese entrepreneur Tommaso Giulini, a former board member at Internazionale.
The season was also influenced by serious financial problems surrounding Parma, involving two controversial takeovers during the season, its last chairman Giampietro Manenti being arrested on 18 March 2015 under accusation of money laundering, and the club being ultimately declared insolvent by the local court on the very next day.
The Serie A this season had the most goals on average than any of the five other top leagues in Europe.
