Changbin

Seo Changbin (서창빈) is the main rapper, sub-vocalist, and producer of Stray Kids, the eight-member JYP Entertainment group that redefined fourth-generation K-pop. Born August 11, 1999, in Yongin, South Korea, he graduated from Bora High School before studying at Gukje Cyber University in the Department of Entertainment. Changbin debuted with Stray Kids on March 26, 2018, with the mini album I am NOT. Before debut, he was already active as a co-founder of 3RACHA, an in-house rap and production sub-unit he formed with Bang Chan and Han during their trainee years, releasing underground mixtapes on SoundCloud without the company's knowledge. In February 2023, all three members were promoted to regular membership in KOMCA (Korea Music Copyright Association). As of late 2025, Changbin holds credits for over 198 registered songs. His output extends well beyond group work. He appeared as a contestant on Show Me the Money 9 (2020), released the Samsung campaign track "Fly High" for the Galaxy Z Flip 5 (2023), collaborated with Kim Chang-wan on "8th grader (Respect your dreams)" for the Galaxy S24 launch (2024), and was featured on "VAY" from ITZY's EP Gold (October 2024), for which he also co-wrote the track. His solo track "ULTRA" appeared on the group's compilation ATE (2024). Off-stage, he has drawn recognition for philanthropy, donating 100 million KRW to emergency relief funds. In 2026, Changbin was appointed the first global brand ambassador for American sneaker label Autry, fronting the brand's Spring 2026 campaign. His profile in fashion and culture continues to grow alongside Stray Kids' mounting global footprint.
