Kim Eun Jung is a South Korean singer, dancer, lyricist and former member of JEWELRY (쥬얼리). She graduated from Incheon Foreign Language High School and later obtained a bachelor's degree in Geography from Sangmyung University.

She made her debut in February 2008 when she joined as the group's new leader and lead vocalist with their fifth album, "Kitchi Island". JEWELRY debuted in March 2001; however, Star Empire (스타제국) decided to make lineup changes as soon as the promotional period for their first album ended. The agency was never able to provide stability for the group as their concept kept changing radically from album to album. In February 2006, two members decided to leave and she was brought in as a replacement.

The lead single of this album, "One More Time", became their biggest hit and was able to top several digital charts and reached the top spot on MBC's "Music Core" and KBS's "Music Bank" just two weeks after the song's debut. Unfortunately, the lineups kept changing and even with new members, the group was not able to promote as much as their comebacks were delayed due to their individual activities.

In January 2009, she became part of the group's first sub-unit, JEWELRY-S, and debuted with the digital mini-album, "Sweet Song".

In March 2014, her contract expired and the agency officially announced the group's disbandment in January 2015.

She reunited with 3 other former members in 2018 and then again in 2022 for special episodes of variety shows where they performed their biggest hit, "One More Time".

She is currently not represented by any agency and is now focused on her work as a lyricist (under the pseudonym Yorkie). She has written lyrics for TWICE ("Pit-A-Pat"), Taeyeon ("I Blame You"), and Kang Daniel ("What Are You Up To"), among others.
