Wu Chia-yen (吳佳晏, born 25 March 2004) is a Taiwanese professional golfer who plays on the LPGA of Japan Tour.
Amateur career In the quarter-finals of the 2017 U.S. Women's Amateur, Wu prevailed over Lauren Stephenson to win in a 30-hole match, the longest in United States Golf Association history. It broke the previous record of 28 holes set at the 1930 U.S. Amateur and 1960 U.S. Junior Amateur.
At only 13 years and four months, she became the youngest player in history to advance to the semi-finals of the U.S. Women's Amateur.
Professional career Wu turned professional in 2020 and won seven times on the Taiwan LPGA Tour before joining the LPGA of Japan Tour in 2023, where she quickly secured three victories on the tour's development circuit, the Step Up Tour. By the end of 2023, she had advanced to 152nd in the Women's World Golf Rankings, and was the second highest ranked Taiwanese player behind Chien Pei-yun.
Wu won the Daio Paper Elleair Ladies Open in 2025, her first title on the LPGA of Japan Tour. Republished as:
