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.

Kata originally were teaching/training methods by which successful combat techniques were preserved and passed on. Practicing kata allowed a company of persons to engage in a struggle using a systematic approach, rather than as individuals in a disorderly manner.

The basic goal of kata is to preserve and transmit proven techniques. By practicing in a repetitive manner the learner develops the ability to execute those techniques and movements in a natural, reflex-like manner. Systematic practice does not mean permanently rigid. The goal is to internalize the movements and techniques of a kata so they can be executed and adapted under different circumstances, without thought or hesitation. A novice’s actions will look uneven and difficult, while a master’s appear simple and smooth.
