Ann Roth is an American costume designer for films and Broadway theatre. She began her career as a scenery painter for the Pittsburgh Opera. She intended to remain in the field of production design until she met Irene Sharaff at the Bucks County Playhouse. Sharaff invited her to California to assist her with costumes on the film Brigadoon and suggested Roth apprentice with her for five films and five Broadway productions before setting out on her own. In 2011, she was inducted into the American Theatre Hall of Fame.
