Prince Silverwings was a abortive theater piece prepared by L. Frank Baum for a projected summer 1904 production. The planned play was Baum's theater adaptation of Edith Ogden Harrison's 1902 book Prince Silverwings and Other Fairy Tales. Ogden Harrison was a prolific author of children's books and fantasy tales in Baum's generation, as well as the First Lady of Chicago — she was the wife of mayor Carter Henry Harrison IV. Production of the play was forestalled by the Iriquois Theater Fire of 30 December 1903, which resulted in 570 deaths and forced a closure of all Chicago theaters.
