A total of 10 teams competed in the league: the 9 best teams from the 2016–17 season and the 2016–17 Swiss Challenge League champion Zürich. The season started on the weekend of 22–23 July 2017 and ended on 19 May 2018 with a break between 17 December 2017 and 2 February 2018.
This season saw the introduction of changes in the way Swiss clubs may qualify for European competition; per new UEFA rules, the champions of the Swiss Super League now qualifies for the Champions League play-off round (previously directly to the Champions League group stage) and the runners-up now qualifies for the Champions League second qualifying round (previously to the third qualifying round). Qualification to Europa League spots for the third- and fourth-placed team remain unchanged.
