The 1989 Nabisco Dinah Shore was a women's professional golf tournament, held March 30 to April 2 at Mission Hills Country Club in Rancho Mirage, California. This was the 18th edition of the Nabisco Dinah Shore, and the seventh as a major championship. Juli Inkster won the second of her two Dinah Shores, five strokes ahead of runners-up JoAnne Carner and Tammie Green. She led wire-to-wire and entered the final round with a five-stroke lead. It was the third of Inkster's seven major titles, although the fourth came over a decade later.
