Kenjutsu (剣術), meaning "the art of the sword", is a term for classical Japanese sword arts (or koryū), in particular those which predate the Meiji Restoration. It is sometimes used more generally to describe any martial art which makes use of the Japanese sword.

The exact activities undertaken when practicing kenjutsu vary with school, but commonly include practice of basic techniques (kihon) without opponent and techniques where two persons paired kata (featuring full contact strikes in some styles). Historically schools incorporated sparring under a variety of conditions, from using solid wooden bokutō to use of bamboo sword (shinai) and armor (bogu). In modern times sparring in Japanese swordsmanship is more strongly associated with Kendo.
