Ryujin (류진) is a South Korean rapper and actress under JYP Entertainment. She is the main rapper of the girl group ITZY.
In October 2017, Ryujin auditioned for survival reality show MIXNINE. Having passed the audition, she made it to the number 1 ranking of the girls' team until the final episode, but was eliminated when the boys' team won against the girls', and hence ultimately did not get to debut.
On January 20, she was revealed, along with her fellow members, as a member of ITZY, JYP Entertainment's newest girl group. They debuted on February 12 with the digital single "IT'z Different". Ryujin made her solo debut with Run Away on 22nd December 2023.
