Michelle Sung Wie West (/ˈwiː/; born October 11, 1989) is an American professional golfer who plays on the LPGA Tour.

Her paternal grandfather, Sang-Kyu Wie, a resident of Jangheung, Jeollanam-do, was an emeritus professor at Seoul National University.

[9][10] She enrolled in September 2007 as a freshman, but as a professional golfer, Wie was not eligible under NCAA rules to play for Stanford's golf team.

[18] Wie remained the youngest player to advance to match play in this tournament, until 2014 when Lucy Li surpassed her by one week.

She also became the youngest player to qualify for an LPGA event, the Takefuji Classic held in Wie's home state of Hawaii.

In June 2003, Wie won the Women's Amateur Public Links tournament, becoming the youngest person ever, male or female, to win a USGA adult event.

[22] Wie was given a sponsor's exemption to the 2004 Sony Open in Hawaii, becoming the fourth, and youngest, female to play a PGA Tour event.

Wie started her 2005 season by accepting another sponsor's invitation to play on the PGA Tour at the Sony Open in Hawaii, where she again missed the cut.

Wie played her first professional event in the 2005 LPGA Samsung World Championship, where she was disqualified from a fourth-place finish for signing an incorrect scorecard.

A journalist, Michael Bamberger, reported a day after Wie had completed her round that she had illegally dropped the ball closer to the hole than its original lie.

In the initial Rolex World Golf Rankings in February 2006, Wie was placed third, behind Annika Sörenstam and Paula Creamer, but eventually dropped to 7th, partially due to a limited schedule.

[27] 2006 also involved several competitions against male competitors, starting with the PGA Tour Sony Open, where she again missed the cut, this time by four strokes.

At the SK Telecom Open, a men's tournament in South Korea, she became the second woman (after Se Ri Pak) to make the cut on the Asian Tour, and in addition, reportedly received appearance fees exceeding the event's total prize money.

At this point, Wie had played 14 consecutive rounds of tournament golf without breaking par and had missed the cut in 11 out of 12 tries against men and remained winless against the women.

[31] In 2007, Wie's slump continued, including a four-month hiatus, due to injuries to both wrists, a disqualification, and several missed cuts and withdrawals.

[33][34] Later that year, after finishing one stroke off the lead during the second round of the State Farm Classic, she was disqualified for walking outside of the official tournament area before returning to sign her scorecard.

[45] On November 15, 2009, Wie won her first professional individual tournament, the Lorena Ochoa Invitational in Guadalajara, Mexico, an event on the LPGA Tour limited to the top 36 female golfers in the world as determined by the LPGA money list and Rolex women's world golf rankings, posting a score of thirteen under par 275 for a two-stroke margin over fellow American Paula Creamer, and beating Jiyai Shin, Cristie Kerr and Morgan Pressel by two strokes.

[49] On August 29, 2010, she posted a three-shot win over a full field at the CN Canadian Women's Open, held at St. Charles Country Club in Winnipeg, Manitoba, for her second career professional victory.

[50] In her next LPGA event two weeks later, she finished second in the 54-hole P&G NW Arkansas Championship shooting 201 (−12) and losing to Yani Tseng by one stroke after giving up an overnight three-stroke lead.

[52] On June 22, 2014, Wie won her fourth LPGA Tour event and first major championship, the U.S. Women's Open.

[56] In May 2022, Wie West announced that she would be stepping away from the game following the 2022 U.S. Women's Open,[57] held at Pebble Beach Golf Links on July 6–9.

[58] From the beginning of her public career, Michelle Wie was the subject of controversy expressed by fans, media, peers, and other observers.

Despite the publicity her appearances garnered, Wie made only one cut in a men's tournament: at the rain-shortened 2006 SK Telecom Open on the Asian Tour.

She created controversy when, after finishing tied for 26th at the 2006 British Open, her caddie Greg Johnston was fired over the phone by Wie's then-agent Ross Berlin.

[69] In January 2013, Wie employed Mark Wallington, who caddied for another LPGA professional and European Solheim Cup player, Sophie Gustafson, for three tournaments.

In response to the lack of information and prolonged absence, Brittany Lincicome questioned whether Wie and her parents had fabricated the injury in order to give her a reason to take a break from golf.
