Dena Dietrich (born December 4, 1928) is an American actress.
Born in Pittsburgh, her television credits include recurring roles on The Practice (1970's sitcom), The Ropers, Life with Lucy, and Philly. She made guest appearances on Paul Sand in Friends and Lovers, Life Goes On, NYPD Blue, Murphy Brown, and The Golden Girls. She appeared in such films as The Wild Party and History of the World: Part I. She appeared on Broadway in The Rimers of Eldritch, Here's Where I Belong, and The Prisoner of Second Avenue.
She is perhaps best known for her portrayal of Mother Nature in Chiffon margarine commercials in the early 1970s. Her character mistakes the margarine for real butter, and when she learns otherwise, she ominously replies, "It's not nice to fool Mother Nature!"
