The Sleeping Prince: An Occasional Fairy Tale is a 1953 play by Terence Rattigan, conceived to coincide with the coronation of Elizabeth II in the same year. Set in London in 1911, it tells the story of Mary Morgan, a young actress, who meets and ultimately captivates Prince Charles of Carpathia, considered to be inspired by Carol II of Romania.
