Hrafnagaldr Óðins ("Odin's raven-galdr") or Forspjallsljóð ("prelude poem") is an Icelandic poem in the style of the "Poetic Edda". It is preserved only in late paper manuscripts. In his influential 1867 edition of the "Poetic Edda", Sophus Bugge reasoned that the poem was a 17th-century work, composed as an introduction to "Baldrs draumar". Since then it has not been included in editions of the "Poetic Edda" and not been extensively studied.
