Definition
Assault is an intentional act that creates in another person a reasonable apprehension of imminent harmful or offensive contact. In many jurisdictions it also covers an attempt to commit a battery. Crucially, assault does not require any physical touching—the offense lies in the threat or attempt itself, although the exact definition varies considerably from state to state.
Legal Meaning
At common law, assault and battery were two distinct wrongs. Assault was the act of putting someone in fear of imminent harm, while battery was the harmful or offensive contact that followed. A person could commit an assault without ever laying a hand on the victim—for example, by drawing back a fist or pointing a weapon—because the harm the law addressed was the victim's reasonable apprehension of being struck.
Modern criminal codes treat assault in widely varying ways. Some states retain the traditional split between assault (the threat) and battery (the contact). Others have merged the concepts into a single statute, frequently labeled "assault," that actually punishes physical contact in the way the common law treated battery. A handful of states use the phrase "assault and battery" as one combined offense. Because of this, the same word can mean different things depending on the jurisdiction, and you should always read the specific state statute rather than rely on the common-law label.
Most assault statutes require proof of intent—the defendant must have meant to cause apprehension of harm (or, in merged statutes, meant to cause or recklessly caused contact). Accidental conduct usually does not qualify. The apprehension must also be reasonable and concern imminent harm; a threat of future harm or an idle threat that no reasonable person would fear typically does not amount to criminal assault.
Key Points
- Assault traditionally means a threat or attempt that causes fear of imminent harm—no touching required
- Battery is the actual harmful or offensive contact; many states merge the two terms
- The precise definition of assault varies significantly from state to state
- Intent is usually a required element; truly accidental acts generally are not assault
- The victim's apprehension of harm must be reasonable and concern imminent contact
- Simple assault is typically a misdemeanor; aggravated assault is usually a felony
- Aggravating factors include weapons, serious injury, or protected victims like officers
- Assault is both a crime and a civil tort the victim can sue over for damages
Real-World Example
During a heated argument in a parking lot, Marcus picks up a baseball bat, raises it over his head, and shouts that he is going to hit Dana while stepping toward her. Dana reasonably believes she is about to be struck and backs away. Even though Marcus never makes contact, in a state that follows the traditional rule he can be charged with assault because he intentionally created a reasonable apprehension of imminent harm. If Marcus had actually swung and hit Dana, he would face an additional charge of battery (or, in a merged-statute state, an aggravated assault charge because a weapon was used).
Common Assault Classifications
| Type | Typical Conduct | Usual Classification |
|---|---|---|
| Simple Assault | Threat or minor attempt without a weapon or serious injury | Misdemeanor |
| Aggravated Assault | Use of a deadly weapon or intent to cause serious bodily harm | Felony |
| Assault on a Protected Person | Assault on a police officer, EMT, teacher, or other protected class | Often elevated felony |
| Domestic Assault | Assault against a family or household member | Misdemeanor or felony, with special rules |
| Sexual Assault | Nonconsensual sexual contact (separate statutory scheme) | Felony |
Defenses to an Assault Charge
Because assault is an intent crime, several defenses can apply depending on the facts:
- Self-defense or defense of others: A person may threaten or use reasonable force to protect against an imminent threat. See self-defense for the rules on reasonable force and the duty to retreat.
- Lack of intent: If the act was accidental and the defendant did not intend to cause apprehension or contact, the charge may fail.
- No reasonable apprehension: If no reasonable person in the victim's position would have feared imminent harm—such as an idle threat or a threat of distant future harm—there is no assault.
- Consent: In limited contexts such as contact sports, consent may negate the offense.
- Mistaken identity: Showing the defendant was not the person who committed the act.

Frequently Asked Questions
What is the difference between assault and battery?
Traditionally, assault is the threat or attempt that causes a person to fear imminent harmful contact, while battery is the actual harmful or offensive physical contact. Assault can occur without any touching, whereas battery requires contact. Many states, however, combine the two into a single "assault" or "assault and battery" statute, so the precise definitions depend on your jurisdiction.
Is assault a felony or a misdemeanor?
It depends on the severity and the state. Simple assault is usually a misdemeanor, while aggravated assault—involving a weapon, serious bodily injury, or a protected victim—is typically a felony. The classification, penalties, and the line between the two are defined by each state's criminal code, so the same conduct can be charged differently across states.
Can you be charged with assault if no one was touched or hurt?
Yes. In states that follow the traditional rule, assault can be charged even with no physical contact, because the offense is the threat or attempt that places the victim in reasonable fear of imminent harm. Raising a fist, lunging, or pointing a weapon can all qualify as assault even if the victim is never touched.
What are common defenses to an assault charge?
Common defenses include self-defense or defense of others, lack of intent, consent (in limited contexts), mistaken identity, and the absence of a genuine or reasonable apprehension of harm. Because intent is a key element, showing that the act was accidental or that the alleged victim could not reasonably have feared imminent harm can defeat the charge.
Can assault be both a crime and a civil claim?
Yes. Assault is both a criminal offense prosecuted by the government and an intentional tort the victim can sue over in civil court for money damages. The two proceedings are separate, use different standards of proof, and one can succeed even if the other does not.
