Seo Seoa (Korean: 서서아, born November 27, 2002) is a South Korean professional pool player known for her performances in international nine‑ball and ten-ball competitions. Often referred to as the "Princess of Pool" she competes in both women's and mixed-gender tournaments.
Seo was born in Gwangju, South Korea. She won the 2025 WPA Women's World Nine-ball Championship. Seo is the second South Korean to win the WPA Women's World Nine-ball Championship since Kim Ga-young in 2004 and 2006. She is recognized as a WPBA Elite Pro.
Career
Seo began playing pool in 2013 after her parents encouraged her to take up a sport. In 2017, she competed in the World Junior 9‑Ball Championship in Moscow. Fourteen at the time, she lost in the qualifying rounds to eventual champion—and future rival—Kristina Tkach, 18, before rallying to finish in the top eight. She returned in 2018 and advanced all the way to the final, finishing as runner‑up. After returning home, she left high school in Gwangju and moved to Seoul to train at the Pocket Academy run by Kim Ga-young. In June of the following year, at age 16, she won her first women's national championship.
Seo has competed on the international professional pool circuit, representing South Korea in major nine‑ball tournaments. In July 2025, she became one of the few women to advance to the last 64 of the prestigious World Pool Championship, after defeating two-time world champion Albin Ouschan 9–2 in the early rounds of the event in Jeddah, Saudi Arabia. She was the only female competitor in the field and stood one win away from becoming the first woman to reach the last 32 at the World Pool Championship. She has also competed in domestic events such as the Namwon National Pocket Billiards Championship, where she won the women's division.
Earlier in the 2025 season, Seo won the World 10‑Ball Open (Little Monster International Women's 10‑Ball Open) in Gandia, Spain, defeating world No. 8 Kelly Fisher in the final. She did this shortly after winning the Korean Sport & Olympic Committee President's Cup, demonstrating strong performances in both domestic and international competition.
Seo has also captured titles in regional events, including a victory at the Indonesian International Open as part of the Predator Pro Billiard Series in Jakarta.
