韩国合气道是参考日本大东流合气柔术并加入一些其他武术混合而成的新流派，为韩国人自行发展的一种武术。

韩国合气道创始人崔龙述在七岁的时候被占领朝鲜半岛的日本军队带到日本做工，后来被武田惣角收养。但是武田并不把他当养子看待，而是把他当做家仆，不过崔龙述还是有机会学习大东流合气柔术，并曾在1935年击败前来挑战武田的对手。1943年武田过世后，崔龙述回到韩国大邱并于1951年开设大韩合気柔拳术道场以传授合气柔术。当时韩国于战后学习武术的风气很盛，尤其许多攻击性的武术在此段时间发展很快；受到这种风气影响，崔龙述后来结合了跆拳道的踢技以及拳击道的拳技，于1963年正式完成这套系统，并命名为「合气道」。自此韩国合气道已与日本柔术及日本合气道在不同的路在线发展。

Hapkido (also spelled hap ki do or hapki-do; Hangul: 합기도;hanja: 合氣道) is a highly eclectic Korean martial art. It is a form of self-defense that employs similar joint locks, grappling and throwing techniques to other martial arts, as well as kicks, punches, and other striking attacks. There is also the use of traditional weapons, including knife, sword, rope, jool bong (nunchaku), cane, short stick (dan bong), and middle-length staff (joong bong, gun (analogous to the Japanese jō), bō (Japanese)) which vary in emphasis depending on the particular tradition examined.
