The 2011–12 Serie A was the 110th season of top-tier Italian football, the 80th in a round-robin tournament, and the second since its organization under a league committee separate from Serie B. It began on 3 September 2011 and ended on 13 May 2012. The league was originally scheduled to start on 27 August, but this was delayed due to a strike by the players. The fixtures were drawn up on 27 July 2011.
