Donna Douglas (born September 26, 1933) is a Louisiana-born American actress and real estate agent, primarily known for her character-type roles. The naturally blonde-headed Donna Douglas is best-known for her role as the daughter of Jed Clampett (portrayed by actor Buddy Ebsen), Elly May Clampett, in the long-running TV series The Beverly Hillbillies, which made her one of the most popular television stars of the 1960s.

An honest to goodness Southern Belle (similar to her most famous role as "Elly May" on "Beverly Hillbillies, The" (1962)), Donna Douglas grew up in Louisiana loving "critters." She got married soon after high school, had a son, divorced and won a couple of beauty contests, all within the span of a few years. She moved to New York and soon was getting acting gigs on television shows, including a well-remembered guest shot on "Twilight Zone, The" (1959) in one of the series' most famous episodes, "Eye of the Beholder", in which she plays a woman who tries to undergo a series of experimental treatments to make her beautiful, only for the treatments to fail. The twist was she *was* beautiful (at least to the viewers) but considered hideous to the "pig people" of her planet. Soon after she got the role of "Elly May" on one of the greatest situation comedies of all time, "Beverly Hillbillies, The" (1962).
