The Winchester Model 1887 and Winchester Model 1901 are lever-action shotguns originally designed by famed American gun designer John Browning and produced by the Winchester Repeating Arms Company during the late 19th and early 20th centuries. The shotgun has become iconic for its use in the 1991 film Terminator 2: Judgment Day.

A lever action is a type of action for repeating firearms that uses a manually operated cocking handle located around the trigger guard area that pivots forward to move the bolt via internal linkages, which will feed and extract cartridges into and out of the chamber, and cock the firing pin mechanism. This contrasts to other type of repeating actions such as the bolt-action, pump-action, semi-automatic, fully automatic, and/or burst mode actions. A firearm using this operating mechanism is colloquially referred to as a levergun.
