Midas is a verse drama in blank verse by the Romantic writers Mary Shelley and Percy Bysshe Shelley. Mary wrote the drama and Percy contributed two lyric poems to it. Written in 1820 while the Shelleys were living in Italy, Mary Shelley tried unsuccessfully to have the play published by children's magazines in England in the 1830s; however, it was not published until A. Koszul's 1922 scholarly edition. Whether or not the drama was ever meant to be staged is a point of debate among scholars. The play combines the stories of the musical contest between Apollo and Pan and that of King Midas and his ability to turn everything he touches to gold.
