The 2012–13 Swiss Challenge League was the tenth season of the Swiss Challenge League, the second tier of the Swiss football league pyramid. It began on 14 July 2012[2] and ended on 2 June 2013.
Teams
2011–12 Challenge League champions St. Gallen were promoted to the 2012–13 Super League. They weren't replaced by another team due to Neuchâtel Xamax being demoted to the 4th tier of Swiss football for financial irregularities. 2011–12 Challenge League runners-up Aarau had to compete in a promotion/relegation playoff against 9th-placed Super League team Sion and remained in the Challenge League after losing 3–1 on aggregate.
