Rhonda Jo Petty (born March 30, 1955 in North Hollywood, California) is an American pornographic actress. She is a member of the AVN Hall of Fame. Petty was raised in Chatsworth, California. Her first starring role was in Disco Lady (1978), a role she earned due to her physical resemblance to mainstream actress Farrah Fawcett, who was popular at the time. Her porn alias Sarah Dawcett was in relation to her resemblance of Fawcett. Petty was popular because she was unique for her time during the 1970s. This was due in part to the facts that she shaved her privates and she often took part in fisting scenes, neither of which were common in that era. She performed in numerous films with early porn icon John Holmes in addition to performing often in lesbian scenes. Her career was at its height in the late 1970s and early to mid 1980's.
