Kata (型 or 形, literally: "form"^?) is a Japanese word describing detailed choreographed patterns of movements practised either solo or in pairs. The term form is used for the corresponding concept in non-Japanese martial arts in general.

Kata are used in many traditional Japanese arts such as theater forms like kabuki and schools of tea ceremony (chadō), but are most commonly known for the presence in the martial arts. Kata are used by most traditional Japanese and Okinawan martial arts, such as aikidō, iaidō, jōdō, jūdō, jūjutsu, kenjutsu, kendō and karate. Other arts such as t'ai chi ch'uan and taekwondo feature the same kind of training, but use the respective Chinese and Korean words taolu and hyeong, respectively.
