Christopher Chahn Bahng (born 3 October 1997), known professionally as Bang Chan (), is an Australian singer, rapper, songwriter, and record producer based in South Korea. Signed to JYP Entertainment, he is the leader of the South Korean boy band Stray Kids and a member of 3Racha, an in-house production team and sub-unit of Stray Kids.

Bang Chan played a pivotal role in forming Stray Kids by selecting trainees, naming the group, and designing its logo.

Beyond creating music for Stray Kids, he has composed for TV series like Pop Out Boy!, Tower of God, and Re:Revenge – In the End of Desire, as well as films including Doraemon: Nobita's Sky Utopia and Deadpool & Wolverine. Bang Chan has also written songs for artists such as JO1, Yao Chen, and Show Lo, and collaborated with Alesso, Sky-Hi, Tiger JK, Lil Durk, and Japanese singer Lisa.
