Gun Fight, known as Western Gun in Japan and Europe, is a 1975 arcade shooter game designed by Tomohiro Nishikado, and released by Taito in Japan and Europe and by Midway Games in North America. It was the first video game to depict human-to-human combat, while the Midway version was also the first video game to use a microprocessor. Following its November 1975 release in North America, it went on to sell over 8,000 arcade cabinets in the United States. It was ported to the Bally Astrocade video game console as a built-in game in 1977 as well as several home computer platforms.

Gunfighter and gunslinger are literary words used historically to refer to men in the American Old West who had gained a reputation of being dangerous with a gun and had participated in gunfights and shootouts. Gunman was a more common term used for these individuals in the 19th century. Today, the term "gunslinger" is now more or less used to denote someone who is quick on the draw with a pistol, but can also refer to riflemen and shotgun messengers. The gunfighter is also one of the most popular characters in the Western genre and has appeared in associated films, video games, and literature.
