Entfernet euch, ihr heitern Sterne, BWV 1156, is a birthday cantata by Johann Sebastian Bach. He composed it in Leipzig to celebrate the 57th birthday of the Elector of Saxony, King Augustus II the Strong, and it was performed for him on his birthday, 12 May 1727, on the Markt square of Leipzig, by students of the University of Leipzig, with Bach directing. The king was also presented with the work's libretto, written by Christian Friedrich Haupt.
