Rubber bullets are rubber or rubber-coated projectiles that can be fired from either standard firearms or dedicated riot guns. They are intended to be a non-lethal alternative to metal projectiles. Like other similar projectiles made from plastic, wax, and wood, rubber bullets may be used for short range practice and animal control, but are most commonly associated with use in riot control and to disperse protests. These types of projectiles are more correctly called baton rounds. Rubber projectiles have largely been replaced by other materials as rubber tends to bounce uncontrollably.

Such "kinetic impact munitions" are meant to cause pain but not serious injury. They are expected to produce contusions, abrasions, and hematomas. However, they may cause bone fractures, injuries to internal organs, or death. In a study of 90 patients in Northern Ireland, one died, 17 suffered permanent disabilities or deformities and 41 required hospital treatment after being fired upon with rubber bullets.
