Carroll's daughter, Susan Kay, told The Associated Press her mother died Friday in Los Angeles of cancer.
During her long career, Carroll earned a Tony Award for the musical "No Strings" and an Academy Award nomination for "Claudine."
But she was perhaps best known for her pioneering work on "Julia." Carroll played Julia Baker, a nurse whose husband had been killed in Vietnam, in the groundbreaking situation comedy that aired from 1968 to 1971.
