2011–12 Swiss Super League
The 2011–12 Swiss Super League season was the 115th season of top-tier football in Switzerland. It began on 16 July 2011 and ended on 23 May 2012.
Basel successfully defended their title. No team was directly relegated after Neuchâtel Xamax were expelled midway through the season over severe financial irregularities.
The league comprised the best eight sides from the 2010–11 season, the 2010–11 Swiss Challenge League champions Lausanne-Sport, and Servette, the winners of the relegation/promotion play-off between the ninth-placed Super League team and the Challenge League runners-up.
Since Switzerland dropped from thirteenth to sixteenth place in the UEFA association coefficient rankings at the end of the 2010–11 season, the league lost its second spot for the UEFA Champions League. The league champions will now enter the second qualifying round of the 2012–13 tournament, while the runners-up and third-placed sides will enter the second qualifying round of the 2012–13 UEFA Europa League.

Sion won 2–1 on aggregate.
Results
All ten clubs played twice against each other during the first half of the season, once at home and once away, for a total of 18 matches. As Neuchâtel Xamax had their license revoked during the winter break, the club's second-half matches were entirely cancelled. The second half of the season thus was competed by only nine clubs, which played another double round-robin schedule; each of these nine clubs hence had played 34 matches at the end of the season.First half of season
