Gunfighters, also called gunslingers, or in the late 19th and early 20th century, gunmen were individuals in the American Old West who gained a reputation of being dangerous with a gun and participated in shootouts. Today, the term "gunslinger" is more or less used to denote someone who is quick on the draw with a handgun, but this can also refer to those armed with rifles and shotguns. The gunfighter is also one of the most popular characters in the Western genre and has appeared in associated films, television shows, video games, and literature.

Fast draw, also known as quick draw, is the ability to quickly draw a handgun and accurately fire it upon a target in the process. This skill was made popular by romanticized depictions of gunslingers in the Western genre, which in turn were inspired by famous historical gunfights in the American Old West.
