Yentl is a play by Leah Napolin and Isaac Bashevis Singer.
Based on Singer's short story "Yentl the Yeshiva Boy," it centers on a young girl who defies tradition by discussing and debating Jewish law and theology with her rabbi father. When he dies, she cuts her hair, dresses as a man, and sets out to find a yeshiva where she can continue to study Talmud and live secretly as a male named Anshel. When her study partner Avigdor discovers the truth, Yentl's assertions that she is "neither one sex nor the other" and has "the soul of a man in the body of a woman" suggest the character is undergoing a gender identity crisis, especially when she opts to remain living as Anshel for the rest of her life.
After eleven previews, the Broadway production, directed by Robert Kalfin, opened on October 23, 1975 at the Eugene O'Neill Theatre, where it ran for 223 performances. The cast included Tovah Feldshuh, John Shea, and Lynn Ann Leveridge.
