Kim Kaphwan is a character in both the Fatal Fury and The King of Fighters series by SNK. Kim is a master of Taekwondo and considers himself a fighter of justice. Kim's original teammates, Chang Koehan and Choi Bounge, were to be teamed up with another dangerous criminal character to form the "Fugitive Team", but Kim was added to the team instead. His official nickname is The Crown Jewel of Taekwondo.

In Fatal Fury, Kim Kaphwan is the reigning world champion of Tae Kwon Do. Kim is invited by Wolfgang Krauser to compete in his King of Fighters tournament as he was hoping to face superb challengers. During the tournament Kim encounters the "Lone Wolf", Terry Bogard. Kim acknowledges Terry as the superior fighter and the duo become good friends. From that moment on Kim helps Terry in all that he can, though a definite (but friendly) rivalry is maintained.

Kim is considered a sport and national hero in his native Korea. This status is what enabled him to convince the authorities to give him custody over Chang Koehan and Choi Bounge to rehabilitate them of their criminal ways. Although both men resented Kim for his actions, they have since grown to grudgingly respect him. In most of his King of Fighters appearances, he has been team captain of Team Korea.
