The Brandenburglied (also known under the title of "Märkische Heide", or Märkish Heath) was a music piece written by Gustav Büchsenschütz (1902–1996) for the Province of Brandenburg, then within the Kingdom of Prussia of the German Empire.

It was used in the province from 1920's to 1936.

In present days it is used as unofficial anthem of the German federal state of Brandenburg.

There is an adaptation of this melody by the Chilean Army, which named Mi Fusil y Yo (My rifle and me).^[1]
