The Wild Duck is a play by Henrik Ibsen, written in 1884.

The Wild Duck is considered by many to be Ibsen's finest work, and it is certainly the most complex. It tells the story of Gregers Werle, a young man who returns to his hometown after an extended exile and is reunited with his boyhood friend Hjalmar Ekdal. Over the course of the play the many secrets that lie behind the Ekdals' apparently happy home are revealed to Gregers, who insists on pursuing the absolute truth, or the "Summons of the Ideal". Among these truths: Gregers' father impregnated his servant Gina, then married her off to Hjalmar to legitimize the child. Another man has been disgraced and imprisoned for a crime the elder Werle committed. And while Hjalmar spends his days working on a wholly imaginary "invention", his wife is earning the household income.
