Christopher Chahn Bahng, known professionally as Bang Chan, is a Korean-Australian singer, rapper, songwriter, and record producer under JYP Entertainment. He is the leader of the boy group Stray Kids and its sub-unit 3Racha.

Bang Chan played a pivotal role in forming Stray Kids by selecting trainees, naming the group, and designing its logo. The survival show Stray Kids documented this process, focusing on whether Bang Chan's team would debut together, unlike typical survival shows where agency management determines the lineup.
