An Se-young made her international debut at the 2015 Asian Junior Championships, quickly establishing herself as a formidable talent in women’s singles badminton. Her consistent high performance in junior tournaments led to her selection for the national senior team in 2017, a historic achievement for South Korean badminton. Her senior career quickly gained momentum in 2019 when she secured her first BWF World Tour title at the New Zealand Open. This breakthrough was followed by victories at the Canada Open, Akita Masters, French Open, and Korea Masters, propelling her into the top 10 of the BWF world rankings.
The BWF recognized her rapid ascent by naming her the 2019 Most Promising Player of the Year. An Se-young continued her dominant streak into 2021, notably winning three consecutive tournaments at the Indonesia badminton festival: the Indonesia Masters, Indonesia Open, and BWF World Tour Finals. Her success further expanded in the 2022 season, where she claimed titles at the Korea Open, Malaysia Masters, and Australian Open. That same year, she played a pivotal role in South Korea’s Uber Cup victory and secured bronze medals at both the Asian and World Championships.
Further solidifying her influence within the badminton community, An Se-young was elected to the BWF Athletes’ Commission in October 2025, demonstrating her standing as both a leading competitor and a respected voice for athletes worldwide.
