Kim Hyun-joo (born April 24, 1978) is a South Korean actress. She is best known for starring in the television dramas Glass Slippers (2002), Miss Kim's Million Dollar Quest (2004), The Land (2004), and Twinkle Twinkle (2011).
Kim Hyun-joo began modeling in teen magazines when she was in third year high school. In 1996, she made her entertainment debut when she starred in the music video for Kim Hyun-chul's "One's Lifetime." Kim launched her acting career in 1997 in the television drama The Reason I Live (1997). Despite being a newcomer, she was cast in the leading role in the film If It Snows on Christmas (1998) with Park Yong-ha, followed by Calla (1999) with Song Seung-heon.
After doing a few sitcoms, Kim built her resume further by playing supporting roles on television. In 1999, she appeared in the Jang Dong-gun starrer Springtime (also known as Youth), which received low ratings. But the popular Into the Sunlight later that year boosted Kim's career, along with costars Cha Tae-hyun, Jang Hyuk and Kim Ha-neul. In early 2000, she appeared in episode 7 of Song Ji-na's omnibus drama Love Story, titled "Insomnia, Manual and Orange Juice." Kim then landed her first TV leading role in Virtue (Deok-yi), followed by more supporting roles in 2001 with Her House (headlined by Kim Nam-joo) and the historical drama Sangdo (based on Choi In-ho's novel about Joseon merchant Im Sang-ok).
Kim Hyun-joo (also Kim Hyeon-ju, Korean: 김 현주; 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.
