"Fäaschtbänkler" is a Swiss German term that refers to a specific type of folk music band or group that performs at local festivals and celebrations, particularly during the Fasnacht (carnival) season. The term can be translated as "carnival band" or "festival band" in English.

The Fäaschtbänkler, a Swiss band from Kriessern, have established themselves as a fixed presence in the European music scene since their founding in 2008, with over 1,000 concerts.
