The Swiss Super League (known as the Raiffeisen Super League for sponsorship reasons) is the top tier of the Swiss football league system. and has been played in current format since the 2003–04 season. As of May 2016 the Swiss Super League is ranked 12th in Europe according to UEFA's ranking of league coefficients, which is based upon Swiss team performances in European competitions.
The Super League is played over 36 rounds from the end of July to May, with a winter break from mid-December to the first week of February. Each team plays each other four times, twice at home and twice away, in a round-robin.
As teams from both Switzerland and Liechtenstein participate in the Swiss football leagues, only a Swiss club finishing in first place will be crowned champion—should a team from Liechtenstein win, this honor will go to the highest-placed Swiss team. Relative to their league coefficient ranking the highest-placed teams will compete in UEFA competitions—again with exception of teams from Liechtenstein, who qualify through the Liechtenstein Cup. The bottom team will be relegated to the Challenge League and replaced by the respective champion for the next season. The club finishing in 9th place will compete against the second-placed team of the Challenge League in a relegation play-off over two games, home and away, for a spot in the succeeding tournament.
Matches in the Super League employ the use of a video assistant referee.
