The 2005 U.S. Women's Open was the 60th U.S. Women's Open, held June 23–26 at Cherry Hills Country Club in Cherry Hills Village, Colorado, a suburb south of Denver.

The par-71 course was set at 6,749 yards (6,171 m), at an average elevation over 5,300 feet (1,620 m) above sea level.

Birdie Kim holed out from a greenside bunker on the 72nd hole to win her only major (and only LPGA) title, two strokes ahead of runners-up Brittany Lang and Morgan Pressel, both teenage amateurs from the United States.

[1] In the final pairing as a 54-hole co-leader, Pressel needed to hole her chip shot to tie, but it went 20 feet (6 m) past and she bogeyed.

[2][3] Pressel, 17, held a share of the 54-hole lead, with Karen Stupples and amateur Michelle Wie, age 15; Kim was one stroke back in a three-way tie for fourth, with 18-year-old Paula Creamer and Young Jo.
