The 1999 U.S. Women's Open was the 54th U.S. Women's Open, held June 3–6 at Old Waverly Golf Club in West Point, Mississippi, northwest of Columbus. In her twentieth attempt, Juli Inkster won the first of her two U.S. Women's Open titles, five strokes ahead of runner-up Sherri Turner. Inkster, 38, broke the under-par scoring record with a 272 (−16) and became the oldest champion since 1955. It was the fourth of her seven major championships; she also won the next major, the LPGA Championship, three weeks later.
