Charlene Gail Heffner, widely known as Chandi Heffner, is an American philanthropist who became widely known after her unusual relationship with billionaire heiress Doris Duke. Born in Baltimore in 1953, Heffner entered the public spotlight when Duke legally adopted her as an adult in 1988. Their relationship later broke down and led to a major legal dispute over Duke’s estate. Court records confirm the adoption and Heffner’s age at the time, while contemporary reporting documents the later $65.8 million settlement. In later years, Heffner focused much of her public work on philanthropy, medical assistance and animal welfare.
