Horse Eats Hat is a 1936 farce play co-written and directed by Orson Welles (at the time 21 years of age) and presented under the auspices of the Federal Theatre Project. It was Welles's second WPA production, after his highly successful Voodoo Macbeth. The script, by Edwin Denby and Welles, was an adaptation of the classic French farce The Italian Straw Hat (French: Un chapeau de paille d'Italie) by Eugène Marin Labiche and Marc-Michel.
