Early Life and Background
Nanna Koerstz Madsen was born on 23 October 1994 in Smørum, Denmark. She grew up in a country where golf was gaining momentum among young athletes, and she quickly rose through local junior circuits. Her early swing work and competitive temperament earned her a place on the national amateur radar by her late teens.
As an amateur, she captured the 2012 Danish Women’s Match Play Championship and followed it with the 2013 Danish Women’s Stroke Play Championship. That same year, she was the stroke play medalist at the 2013 British Ladies Amateur Championship, posting rounds of 69 and 72. At the close of the 2014 season, she finished as the top European amateur on the World Amateur Golf Ranking.
Madsen also played college golf with the South Carolina Gamecocks women’s golf team at the University of South Carolina, where she won the Mercedes-Benz Intercollegiate. After just one semester, she decided to leave the program and pursue a professional career, accelerating her path to the professional tours.
Path to Professional Golf
Madsen earned her LET card by winning the Lalla Aicha Tour School Final Qualifying event, and she debuted as a Ladies European Tour rookie in 2015. In her rookie season, she finished 9th on the Order of Merit, an impressive start against a deep international field. The following year, she captured the 2016 Tipsport Golf Masters and finished 6th on the Order of Merit, cementing her status as one of Europe’s promising young players.
Determined to compete in the United States, she dedicated the 2017 season to the Symetra Tour, where she became a three-time winner. Her dominant season made her the 12th player to earn a Battlefield Promotion to the LPGA Tour, allowing her to play in three events between late August and early September. She began her rookie season on the LPGA Tour at the start of 2018.

Early Career (2015-2016)
Madsen opened her professional career on the Ladies European Tour in 2015 and immediately showed consistency, finishing 9th on the Order of Merit in her rookie year. Her precision off the tee and steady ball-striking translated well to a wide variety of European courses. The success in her first season gave her the confidence to set her sights on bigger stages.
In 2016, she captured her first professional title at the Tipsport Golf Masters and ended the year 6th on the Order of Merit. The victory validated her decision to turn professional and provided crucial experience closing out tournaments under pressure. By the end of 2016, she had laid the foundation for a transatlantic career.
LPGA Tour Breakthrough (2018-2022)

Her career-defining moment came in 2022, when she captured the Honda LPGA Thailand to become the first Dane ever to win an LPGA Tour event. After a hard-fought battle with China’s Lin Xiyu, Madsen drained a 10-foot eagle putt on the second playoff hole to claim the title. Following the win, her Rolex Women’s World Golf Ranking jumped 22 places, from No. 55 to No. 33.
Honda LPGA Thailand Win (2022) and Continued Rise (2023-2025)
The 2022 Honda LPGA Thailand victory remains the cornerstone of her LPGA Tour resume. It gave Denmark its first winner on the circuit and elevated Madsen into the upper tier of international women’s golf. The playoff eagle against Lin Xiyu became an instant highlight in her highlight reel.
After a playoff loss to Atthaya Thitikul at the JTBC Classic on 27 March 2023, her world ranking rose 13 places to No. 19, reflecting her growing consistency. She posted a T11 at the 2023 Women’s PGA Championship and has continued to log strong major finishes, including a T5 at the 2021 Women’s British Open and a T16 at the 2019 U.S. Women’s Open.
