Kata ( or , literally: "form"), a Japanese word, are detailed choreographed patterns of movements practiced 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 theatre forms like kabuki and schools of tea ceremony (chado), but are most commonly known for the presence in the martial arts. Kata are used by most Japanese and Okinawan martial arts, such as aikido, judo, kendo, kempo, and karate.

Kata originally were teaching and 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 and to practice self-defense. 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.

Kata is a loanword in English, from the 1950s in reference to the judo kata due to Jigoro Kano, and from the 1970s also of karate kata; but the word has come to be used as a generic term for "forms" in martial arts in general, or even figuratively applied to other fields.

In Japanese martial arts practice, kata is often seen as an essential partner to randori training with one complementing the other. However, the actual type and frequency of kata versus randori training varies from art to art. In iaido, solo kata using the Japanese sword (katana) comprises almost all of the training. Whereas in judo, kata training is de-emphasized and usually only prepared for dan grading.
