Jin Young Ko

Jin Young Ko (고진영) is a South Korean professional golfer who competes on the LPGA Tour. Born on July 7, 1995, in Seoul, she turned professional in 2013. She is widely regarded as one of the most dominant players in the history of women's golf, having held the world number one ranking on the Rolex Women's World Golf Rankings for a record 159 weeks, surpassing Lorena Ochoa's previous record of 158 weeks in June 2023.

Ko joined the LPGA Tour in 2018 and made an immediate impact, winning the ISPS Handa Women's Australian Open in just her first tournament as a Tour member, only the second player in LPGA history to accomplish that feat. She was named LPGA Rookie of the Year that season. Her breakout came in 2019, when she won two LPGA majors: the ANA Inspiration (now the Chevron Championship) and the Evian Championship. She closed that year with the LPGA money title and the Vare Trophy for lowest scoring average. By 2021 she had tied Annika Sorenstam's 16-year-old record of 14 consecutive rounds in the 60s, a stretch that underlined her extraordinary consistency. She has accumulated 15 LPGA Tour victories in total, along with 12 wins on the LPGA of Korea Tour earlier in her career.

Ko's game is built on precision and composure rather than power. She is known for exceptional ball-striking accuracy and a near-elimination of bogeys from her scoring. During the 2019 Canadian Women's Open she completed all 72 holes without recording a single bogey, shooting a tournament-record 26-under-par. Following her peak years between 2019 and 2022, her last LPGA win came at the Founders Cup in May 2023. She has remained active on Tour through the 2026 season, contending at events including the Kroger Queen City Championship in Cincinnati in May 2026.
