Saint Joan is a play by George Bernard Shaw about 15th-century French military figure Joan of Arc. Premiering in 1923, three years after her canonization by the Roman Catholic Church, the play dramatises what is known of her life based on the substantial records of her trial. Shaw studied the transcripts and decided that the concerned people acted in good faith according to their beliefs. He wrote in his preface to the play:
There are no villains in the piece. Crime, like disease, is not interesting: it is something to be done away with by general consent, and that is all [there is] about it. It is what men do at their best, with good intentions, and what normal men and women find that they must and will do in spite of their intentions, that really concern us.
Michael Holroyd has characterised the play as "a tragedy without villains" and also as Shaw's "only tragedy". John Fielden has discussed further the appropriateness of characterising Saint Joan as a tragedy.
The text of the published play includes a long Preface by Shaw.
