Lee Eun-Jin (Korean: 이은진, born March 17, 1979), better known by her stage name Yangpa (Korean: 양파, meaning "onion"), is a South Korean singer. She studied at Berklee College of Music in Boston, Massachusetts.
Yangpa debuted in 1996 with the album Novice's Love which had the greatest success in her career. Her second I Want to Know album was moderate successful, as was her third album, Addio.
Although active at the beginning of the decade, Yangpa began to experience health issues, causing her to go on hiatus. She released an album in 2007 titled The Windows Of My Soul and collaborated with the singer Miho, but her activities were short lived and she once again went on a break.
In early 2011, it was announced that Yangpa had signed onto Core Contents Media and would be making her comeback after her four-year absence. Her EP, Elegy Nouveau, was released on March 28, 2011, which contained the self-composed tracks "Bon Appetit" and "그때 그 사람". After the concept photos for the album were released, controversy aroused over whether or not the singer had gotten cosmetic surgery. Her agency initially denied the claims, but Yangpa stated in a later interview that she had some work done.
