Margaret L. "Peg" Murray (born February 14, 1924, Denver, Colorado) is an American actress of stage, musical theatre and television.
Murray won a Tony Award for her performance as the vile "Fraulein Kost" in the original production of Cabaret, directed by Hal Prince. Murray also understudied the role of "Fraulein Schneider", originated by Lotte Lenya, and eventually took over that role full time when Lenya left the production.
She later worked in daytime television playing the roles of Carrie Johnson Lovett on Love of Life and modeling agent Olga Swenson on All My Children. She also substituted for Constance Ford for several weeks as Ada Hobson on Another World. She starred in the very brief-lived unsuccessful NBC-TV sitcom, Me & Mrs. C.
