Cristie Kerr (born October 12, 1977) is an American professional golfer who plays on the LPGA Tour. She has 20 wins on the LPGA Tour, including two major championships, and over $19 million in career earnings. Kerr was the number one-ranked golfer in the Women's World Golf Rankings for three time periods in 2010. She is naturally left handed but plays golf right handed.

Kerr was born in Miami, Florida, and started playing golf at the age of eight. She had a successful amateur career, winning the 1994 Junior Orange Bowl International Golf Championship and the 1995 Women's Western Amateur. She was the 1995 American Junior Golf Association Junior Player of the Year. In 1996 she played in the Curtis Cup and was the low amateur at the U.S. Women's Open. She graduated from Miami Sunset High School in West Kendall, Florida.

Kerr's first win in a professional tournament came in April 1995 in the Ironwood FUTURES Classic on the Futures Tour, which she played while still an amateur.

She turned professional in 1996 at age 18 after graduating from high school, playing on both the Futures Tour and Players West Tour. In October 1996, she tied for sixth at the LPGA Final Qualifying Tournament to gain exempt status for 1997. Her LPGA career started fairly slowly; she broke into the top fifty on the money list in her third season in 1999, but did not win until her sixth season. In 2002, she won her first LPGA event at the Longs Drugs Challenge in California. By 2004, she was one of the leading players on the tour, with three tournament victories, and a fifth-place finish on the money list. She won two tournaments in 2005 and moved up to third on the money list. She tied for second at the 2000 U.S. Women's Open, matched by her performance in the 2006 Women's British Open. Her first win of 2006 came at the Franklin American Mortgage Championship where she posted a tournament-record score of 19 under par. In 2006, she was the only American to win more than one event on the LPGA Tour, winning three times. She won the 2007 U.S. Women's Open, her first major championship. She was also a member of the United States Solheim Cup team in 2002, 2003, and 2005.

The hallmarks of Kerr's game are putting; she finished in the top five on the LPGA Tour in putts/greens hit in 2005 and 2006 and iron play. She was fifth in greens-in-regulation in 2005. In 2005, Kerr finished in the top 10 in half of the tournaments she entered, and ranked second in the LPGA in scoring average, trailing only Annika Sörenstam.

In 2010, Kerr won two of the first 10 tournaments on the LPGA Tour, including the LPGA Championship, which she won by a record-breaking 12-stroke margin over the second-place finisher Song-Hee Kim. As a result of this finish, she went to the top of the Women's World Golf Rankings on June 28, 2010. Kerr held the position for three weeks before Ai Miyazato again regained the top ranking by a margin of 0.0006 average points.

In 2015, Kerr won the CME Group Tour Championship by one shot over fellow American Gerina Piller and South Korean Jang Ha-na. That year she made 24 cuts out of 25 events, captured her 17th career victory at the Kia Classic and posted a 3–0–1 record at her eight Solheim Cup, helping the U.S. team to victory.

In 2016, she recorded four top-10 finishes, including a tie for seventh at the LPGA KEB Hana Bank Championship. She was also on the victorious U.S. team at the UL International Crown, where she posted a team-best 3–1–0 record. In 2017, Kerr recorded her 19th and 20th career wins, moving her into a tie with Laura Davies for 26th all-time on the LPGA career wins list. That year she also participated in her ninth Solheim Cup for the U.S., posting a 3–0–1 record, thereby surpassing Juli Inkster for the all-time lead in points recorded by a U.S. player in Solheim Cup history (21). In 2018, Kerr recorded two top-10 finishes, with a season-best finish tied for second at the Kia Classic
