Schack von Staffeldt or Adolph Wilhelm Schack von Staffeldt was a Danish author of two collections of poetry. He is famous for "being late", publishing his collection of poetry intended to introduce Romanticism in Denmark a year after his younger rival, Adam Oehlenschläger did it. Staffeldt was not held in high regard in his own time but is acknowledged as one of the most important Romantic Danish poets by later generations.
