Eunji (은지) is a South Korean singer and performer who belongs to the most recognized lineup of the girl group Brave Girls, now active under the name BBGirls. She debuted on February 16, 2016 under Brave Entertainment, joining the group's second-generation lineup—the formation that would ultimately define its musical and stage identity.

A turning point arrived in 2021, when the song Rollin'—released years earlier—unexpectedly went viral and became a nationwide sensation in South Korea. The sudden success propelled the group to mainstream fame, and Eunji became widely recognized for her charisma, signature smile, and her ability to connect with audiences during live stages.

After concluding their contracts with Brave Entertainment in 2023, Eunji, Minyoung, and Yuna signed with a new agency and relaunched the group under the name BBGirls.
