Kim Hyun-joo (swimmer)

Kim Hyun-joo (also Kim Hyeon-ju, 김현주; born January 2, 1986) is a South Korean former swimmer, who specialized in freestyle events. She won a total of two bronze medals, as a member of the South Korean team, in the 4 × 100 m freestyle relay (3:44.81) and 4 × 200 m freestyle relay (8:19.62) at the 2002 Asian Games in Busan, South Korea.

Kim qualified for two swimming events at the 2004 Summer Olympics by clearing a FINA B-standard entry time of 2:01.50 (200 m freestyle) from the World Championships in Barcelona, Spain. She also teamed up with Ryu Yoon-ji, Sun So-eun, and Shim Min-ji in the 4 × 100 m freestyle relay. Swimming the anchor leg, Kim recorded a split of 55.83, but the South Koreans missed the final by two seconds outside the top 8, in a time of 3:44.84.

In the 200 m freestyle, Kim challenged seven other swimmers on the fourth heat, including top medal favorite Dana Vollmer of the United States. She rounded out the field to last place by a 1.62-second margin behind Slovenia's Sara Isaković in 2:03.33. Kim failed to advance into the semifinals, as she placed twenty-sixth overall in the prelims.
