1979 U.S. Clay Court Championships – Women's singles

Top-seed Chris Evert-Lloyd won the title beating third-seed Evonne Goolagong Cawley in the final for a first-prize of $20,000. It was Evert-Lloyd's fifth title at the U.S. Clay Courts and followed an absence of three years during which World Team Tennis commitments clashed with the event.
