This is a list of Old West gunfights. Gunfights have left a lasting impression on American frontier history; many were retold and embellished by dime novels and magazines like Harper's Weekly during the late 19th and early 20th century. The most notable shootouts took place in Arizona, California, New Mexico, Kansas, Oklahoma, and Texas. Some like the Gunfight at the O.K. Corral were the outcome of long-simmering feuds and rivalries but most were the result of a confrontation between outlaws and law enforcement.
