Stun guns are legal in a majority of states, including Tennessee. Unlike with firearms, Tennessee laws do not specifically prohibit possession of stun guns by convicted felons. In fact, stun guns are barely mentioned in the statutes, except in relation to unarmed security guards. However, there are other states that prohibit either the possession of stun guns generally, or possession by felons specifically, so even if a felon legally possess a stun gun in Tennessee, he may not be able to do so outside the state.

Tennessee law defines a stun gun as a hand-held device designed and manufactured for self-defense that emits an electrical spark that can momentarily disable a person. There are two prongs at the end of a stun gun. Pulling the trigger while touching the attacker with the prongs causes an electrical current to go from the prongs through the attacker's clothes into his body. The pulsed current can disable a person for up to 30 minutes. Considered a non-lethal weapon, stun guns are not intended to kill or permanently injure the targeted person.
Tennessee, like a majority of states, does not prohibit the possession or use of stun gun in the state. Stun guns are not directly regulated, with the exception of security personnel. Under the law, unarmed security personnel, like security guards, may carry stun guns only if they have successfully completed state-approved training and their employer authorizes use of the stun gun during work.
