Football Club de Sion, commonly known as simply FC Sion or Sion, is a Swiss football team from the city of Sion. The club was founded in 1909, and play their home matches at the Stade Tourbillon. They have won the Swiss Super League twice, and the Swiss Cup in 13 of their 14 appearances in the final, the most recent being in 2015.
FC Sion were founded in 1909 by Robert Gilliard, who became club captain, and played their first match the same year, a 3–2 win against FC Aigle. The club grew thanks to contributions from locals, and played their first competitive league fixture in 1914, again a 3–2 victory, against FC Monthey. In 1919, Sion formally organised its managerial structure, with Gilliard becoming vice-president and Charles Aymon taking the presidency.
