The 1991 Nabisco Dinah Shore was a women's professional golf tournament,[3] held March 28–31 at Mission Hills Country Club in Rancho Mirage, California.

At age 35, Amy Alcott broke her own scoring record to win her third Dinah Shore by eight strokes over runner-up Dottie Pepper,[4] who won the following year.

[6][7] Alcott and caddy Bill Kurre had jumped into the water next to the 18th green after her previous victory in 1988,[8][9] and she was not going to repeat it.

[4] Host Dinah Shore had written the foreword in Alcott's recent book, stating that she would join her in the jump if she won again, so Alcott, Kurre, and Shore took running leap together.

[6][7] The jump became a continuous tradition three years later when Donna Andrews won, followed by Nanci Bowen in 1995.
