Lee Jung-hyun (이정현 born March 13, 1980 in Taegu, South Korea) is a Korean pop singer and actress.

Biography
She made her movie debut at age 16 in Kkonnip (꽃잎, "Petal").

Before releasing her first solo music she featured as a guest vocalist on the Jo PD single "Fever", also appearing in the music video.

Her early solo work is techno-style dance music. Her first single, Wa (와, "Come") topped the Korean charts for three weeks, while her third, Bakkwo (바꿔, "Change") won awards for Best Song and Most Broadcast Song.

With her fifth album, Passion, she changed to a Latin style of music, complete with Spanish Guitar and flamenco-style tap dance.

Many of her songs are sung in an angry mood, from the point of view of a rejected lover.

Chinese singer Sammi Cheng has sung remakes of many Lee Jung Hyun hits such as Bakkwo (became Mei Fei Se Wu in Mandarin/Sat For - Finale in Cantonese), Wa became "Duk Ga See Chung - Exclusive Trial Singing" and Neo(Nuh) (너, You), which became Tian Yi Wu Feng. The remakes have original (non-translated) lyrics sung in Mandarin.

Lee Jung Hyun also released Japanese versions of her early hits Wa and Heaven in December of 2004, and released her first Japanese album, THIS IS HYONY, in 2006.

Evonne Hsu (许慧欣)'s "Lonely Ballet" (孤单芭蕾/Gu Dan Ba Lei) is also a cover of Lee Jung Hyun's "Michyeo" (미쳐/Crazy).

Cyndi Wang (王心凌)'s "HONEY" is also another cover of Lee Jung Hyun's "Summer Dance".
