The batarang is a roughly bat-shaped throwing weapon used by the DC Comics superhero Batman. Batarangs are a staple of Batman's arsenal, appearing in every major Batman television and film adaptation to date.

The name "Batarang" is a portmanteau of bat and boomerang, and was originally spelled "baterang".

The earliest depictions were of scalloped, metal boomerangs used to attack opponents, which quickly flew back to the thrower.

Batarangs are customizable throwing weapons, based on shurikens and boomerangs, and are collapsible so that a large number of them can fit inside of Batman's utility belt.

Batman uses batarang as a weapon of ranged attack, the primary alternative to firearms, which he usually rejects for personal reasons.

Batarangs are used primarily to knock guns and other tools out of an assailant's hand.

They also serve as Batman's calling cards to alert criminal elements of his presence (much like the character's antecedent Zorro, who leaves the mark "Z" to his defeated foes) and props to create an illusion to the superstitious that he commands bats when he throws them.

Although they are named after boomerangs, batarangs have become more like shuriken in recent interpretations.
