Wendy Susan Whiteley OAM (née Julius; 1941) is best known as the former wife of the Australian artist Brett Whiteley, and as the mother of their daughter, actress Arkie Whiteley (1964–2001). She has become a notable cultural figure, particularly since her ex-husband's death in 1992. She posed for Brett many times. Although they divorced three years before he died, she has control of Brett Whiteley's estate including the copyright to his works. She played an important role in the establishment of the Brett Whiteley Studio in Surry Hills, New South Wales which is now owned and managed as an art museum by the Art Gallery of New South Wales.
