2010 U.S. Women's Open

The 2010 U.S. Women's Open was the 65th U.S. Women's Open, played July 8–11 at Oakmont Country Club in Oakmont, Pennsylvania, a suburb northeast of Pittsburgh. Paula Creamer, in her fourth tournament after surgery to her left thumb, won her first major championship, four shots ahead of runners-up Na Yeon Choi and Suzann Pettersen.

It was the second U.S. Women's Open, and 15th overall USGA championship (8 U.S. Open and 5 U.S. Amateur championships also; a 16th has since been hosted) held at Oakmont, which hosted 18 years earlier in 1992; Patty Sheehan won that year, in an 18-hole playoff over Juli Inkster. The Tournament was televised by ESPN and NBC Sports.

Qualifying and field
For the first time since 2001, qualifying for the U.S. Women's Open took place in a single sectional qualifying tournament stage, rather than in a two-stage process of local and sectional qualifying tournaments. Twenty separate sectional qualifying tournaments took place from May 2 through June 3 in 16 states across the United States.

Exempt from qualifying
Players in eleven categories were exempt from qualifying. Players are listed only once in the first category in which they qualify, with additional categories in parentheses next to their names.

1Both Sörenstam and Ochoa have announced their retirement, but are officially listed by the LPGA as "inactive".

2Bo Bae Song was not an LPGA Tour member when she won the Mizuno Classic in 2009. This means that her victory and prize money are not included in LPGA career statistics. However, since the Mizuno Classic is sanctioned by the LPGA as an official money event, Song's victory is considered "official" for purposes of U.S. Women's Open entry.

3Mallon announced her retirement from competitive golf on July 7, 2010, and withdrew from the tournament. She was replaced by alternate Nicole Vandermade.
