Choi Kwang-Do is a martial art derived from Taekwondo created by Grandmaster Kwang Jo Choi. Choi was a chief instructor for the International Taekwondo Federation from 1964 to 1978. His new style, Choi Kwang-Do, was officially inaugurated by him on March 2, 1987. With the goal of creating a safer and more effective martial art, Choi said that he formulated his new style based on bio-mechanical principles.

Choi Kwang-Do adherents say that all movements in their style follow the body's natural movement pattern, and are performed as one sequential movement. Their theory is that power is thereby increased and risk of injury is reduced. In Choi Kwang-do, martial arts competitions are viewed as counter-productive for health and self-defense purposes. Training is geared towards the stated goal of practical responses with maximum power in realistic situations.
