Sir Guy of Gisbourne (also spelled Gisburne, Gisborne, Gysborne, or Gisborn) is a character from the Robin Hood legends of English folklore. He first appears in "Robin Hood and Guy of Gisborne" (Child Ballad 118),[1] where he is an assassin who attempts to kill Robin Hood but is killed by him. In later depictions, he has become a romantic rival to Robin Hood for Maid Marian's love.
