The 2015 U.S. Women's Open was the 70th U.S. Women's Open, held July 9–12 at Lancaster Country Club in Lancaster, Pennsylvania.

The U.S. Women's Open is the oldest of the five current major championships and the third of the 2015 season.

It had the largest purse in women's golf, at $4.5 million in 2015. Additionally, the tournament set an attendance record for the U.S. Women's Open at 135,000 spectators for the week.

The tournament was televised by Fox Sports 1 and Fox Sports.

The championship is open to any female professional or amateur golfer with a USGA handicap index not exceeding 2.4. Players qualify by competing in one of twenty 36-hole qualifying tournaments held at sites across the United States and at international sites in China, England, Japan, and South Korea. Additional players were exempt from qualifying because of past performances in professional or amateur tournaments around the world.

The United States Golf Association received a record 1,873 entries for the championship.
