Subway to Sally is a German folk metal band founded in Potsdam in the early 1990s. Their music has clear folk and medieval influences, later also adding gothic and metal elements. With their continuous inclusion of oriental sounds and elements of classical music and the use of instruments seldom seen in metal bands such as bagpipes, shawm, violin, hurdy-gurdy and lute, Subway to Sally has acquired the label of medieval metal. The band has released 12 studio albums, two live albums, and two live DVDs. Their fame is centered mainly in the German-speaking countries, having played only a handful of concerts outside of that area.

Medieval metal is a subgenre of folk metal that blends heavy metal music with medieval folk music. Medieval metal is mostly restricted to Germany where it is known as Mittelalter-Metal or Mittelalter-Rock. The genre emerged from the middle of the 1990s with contributions from Subway to Sally, In Extremo and Schandmaul. The style is characterised by the prominent use of a wide variety of traditional folk and medieval instruments.
