A shootout, also called a firefight, gunfight, or gun battle, is a combat situation between armed parties using guns. The term can be used to describe any such fight, though it is typically used in a non-military context or to describe combat situations primarily using firearms (generally excluding crew-served weapons, combat vehicles, armed aircraft, or explosives).

Shootouts often pit law enforcement against criminals, though they can also involve groups outside of law enforcement, such as rivalling gangs, militias, or individuals. Military combat situations are rarely called "shootouts", and are almost always considered battles, engagements, or skirmishes.

Shootouts are often depicted in action films, Westerns, and video games.
