Who is the oldest member of BTS?

Jin is the oldest member of BTS, having been born Kim Seok-jin on December 4, 1992.

He is older than the other six members and is often described by fans as the group’s eldest, or “hyung,” a Korean term used by younger men for an older male. Jin joined BTS as a vocalist and became known for his distinctive high register, broad public charm and recurring “worldwide handsome” nickname.

Jin’s path into music was not originally straightforward. He studied film at Konkuk University and initially wanted to pursue acting. Big Hit Entertainment recruited him while he was a university student, and he eventually trained as a singer before BTS debuted in 2013.

Being the oldest member does not make Jin the group’s leader—that role belongs to RM. Jin also developed a substantial solo identity, releasing tracks with BTS before making his official solo debut with the single album The Astronaut in 2022. His age and seniority are therefore separate from leadership or solo prominence.
