Ha Ju Yun, formerly known professionally as Baby-J, is a South Korean singer, dancer, and former member of JEWELRY (쥬얼리). She graduated from Granada Hills Charter High School in Los Angeles and later moved back to South Korea to pursue a career as a singer.

She made her debut in February 2008 when she joined as the group's new main dancer, rapper and sub-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 August 2014, her contract expired, and the agency officially announced the group's disbandment in January 2015. She was part of JEWELRY's third and fourth official lineups. She then went to participate in a few survival rapping competitions without much success.

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 then took time off of the industry around 2019 and worked part-time at a café and even obtained her barista license.

She is currently not represented by any agency and is now a YouTuber.
