Shoot wrestling is a Japanese hybrid grappling style and combat sport. Shoot wrestling incorporates techniques from various wrestling, submission grappling, kickboxing and karate styles. It was particularly inspired and influenced by catch wrestling, a form of wrestling with submissions that was the predominant style of professional wrestling in the 19th and early 20th century, at the time a competitive sport and not yet predetermined.

Shoot wrestling originated in Japan's professional wrestling circuit (puroresu) of the 1970s, particularly stemming from the influence of wrestlers Karl Gotch, Lou Thesz and Billy Robinson, all who had an enduring popularity in Japan due to their serious submission wrestling style. Professional wrestlers of that era attempted to use more realistic or even "full contact" moves in their matches to increase their excitement, diminishing or eschewing the theatrical elements and acrobatics, looking more similar to an actual, unscripted fight. The name "shoot wrestling" comes from the professional wrestling term "shoot", which refers to any unscripted occurrence within a scripted wrestling event.

The first wave of shoot wrestlers were students of Antonio Inoki and Karl Gotch from New Japan Pro-Wrestling (NJPW), two wrestlers which already were advocates of a stiffer and more realistic wrestling style. Their students left NJPW to form the Universal Wrestling Federation (UWF) in 1984, pioneering in the new style.

Shoot wrestling was popular in Japan from the 1980s until the mid-1990s, fading from popularity due the demise of the leading shoot-style promotion UWFi in 1996 and the simultaneous rise of mixed martial arts (MMA) in Japan. Most shoot wrestlers started to migrate to MMA or back to more theatrical forms of professional wrestling. Shoot wrestling had a considerable influence on the sport of mixed martial arts.

Prior to the emergence of the current sport of shoot wrestling, the term was commonly used in the professional wrestling business, particularly in the United Kingdom, as a synonym for the sport of catch wrestling. Shoot wrestling can be used to describe a range of hybrid fighting systems such as shootfighting, shoot boxing and the styles of mixed martial arts done in the Shooto, Pancrase and RINGS promotions. Organizations, promotions and gyms with origins in shoot wrestling are referred as the "U-Kei".

Historically, shoot wrestling has been influenced by many martial arts, most influential of them being catch wrestling, but also freestyle wrestling, Greco-Roman wrestling, and then sambo, karate, Muay Thai and judo in the sport's later stages.

Karl Gotch is one of the most important figures in the development of shoot wrestling. Karl Gotch would begin his journey into wrestling in the German and North American professional wrestling circuits, where Gotch found moderate success. However, it was in his tours of Japan that the early formations of shoot wrestling took place. Gotch was a student of the "Snake Pit" gym, run by the renowned catch wrestler Billy Riley in Wigan. The gym was the centre of learning submission wrestling as practiced in the mining town of Wigan, popularly known as catch-as-catch-can wrestling. It was here that Karl Gotch honed his catch wrestling skills. Karl Gotch also travelled to India to practice the wrestling form of Pehlwani; later on he would propagate the exercises using the "Hindu mace" (large clubs) and would go on to incorporate the Indian system of exercises using push-ups, neck exercises, yogic breathing exercises and "Hindu squats" for conditioning. Gotch attained legendary status in Japan, earning the nickname God of Wrestling. In the 1970s he taught catch wrestling-based hooking and shooting to the likes of Antonio Inoki, Tatsumi Fujinami, Yoshiaki Fujiwara, Satoru Sayama, Masami Soranaka, and Akira Maeda. Most of these professional wrestlers already had backgrounds in legitimate martial arts. Masami Soranaka had been a student of full contact karate, kodokan judo, and sumo. Yoshiaki Fujiwara was already a black belt in judo, while Satoru Sayama had studied Muay Thai with Toshio Fujiwara and went on to study sambo with Victor Koga. This would eventually lead to the added influences of karate, Muay Thai and judo to the wrestling style.

One of Gotch's students, Antonio Inoki, hosted a series of mixed martial arts-style wrestling matches in which he pitted his "strong style professional wrestling" against other martial arts in an attempt to show that professional wrestling and shoot wrestling were the strongest fighting disciplines. Inoki would go on to teach these fighting techniques to a new generation of wrestlers in the dojo of his professional wrestling promotion, New Japan Pro-Wrestling. These matches eventually culminated into the Muhammad Ali vs. Antonio Inoki. While the previous matches were predetermined, Ali and Inoki could not agree on the terms of the match and it turned into a "shoot".
