Formed in 2001, Die Irrlichter ("Irrlicht" being a German expression for Will-o'-the-wisp) is a German band performing medieval folk and fantasy music at concerts, festivals, renaissance fairs, medieval banquets, and similar events in Germany and other European countries.

The band was originally formed as troubadours for a live action role-playing game, but quickly expanded beyond that niche.

During this time, several members dropped out to pursue or concentrate on academic or professional careers as the band gradually evolved from a mere hobby venture into an increasingly professional music project.

Between 2006 and 2008 the band was reorganized around longtime members Brigitta Jaroschek and Stephanie Keup.

They started their own production firm which has been producing the group's albums ever since the fifth.
