Definition
Defamation is a false statement of fact, communicated to a third party, that injures another person's reputation. It takes two forms: libel, which is written or otherwise recorded, and slander, which is spoken. To be actionable, a statement must generally be a false assertion of fact rather than an opinion, must be published to at least one other person, and must cause reputational harm.
Legal Meaning
Defamation is a civil wrong (a tort) that protects a person's reputation against false factual statements. Unlike most other torts on this site, it does not arise from physical injury but from harm to one's standing in the community. The two recognized categories are libel—defamation in a fixed or lasting form such as writing, print, online posts, or broadcasts—and slander—defamation that is spoken.
A plaintiff generally must establish several elements: (1) a false statement of fact about the plaintiff; (2) publication, meaning communication to at least one third party; (3) fault on the part of the speaker, with the required level depending on who the plaintiff is; and (4) harm to the plaintiff's reputation. Each element matters. A statement that is true, that is pure opinion, or that is never communicated to anyone else cannot support a defamation claim.
Defamation sits at the intersection of tort law and the constitutional protection of free speech. That tension has produced special rules—most importantly the heightened "actual malice" standard for public officials and public figures—that make defamation one of the more nuanced areas of civil law. Successful plaintiffs may recover damages for reputational and emotional harm, and in egregious cases punitive damages.
Key Points
- Defamation is a false statement of fact, published to a third party, that harms reputation
- Libel is written or recorded; slander is spoken
- Truth is a complete defense because the statement must be false
- Pure opinion, insults, and hyperbole are generally not defamatory
- Private individuals usually must prove the speaker was at least negligent about the truth
- Public officials and public figures must prove "actual malice"
- Some statements are privileged, such as testimony in court or legislative debate
- Defamation claims often carry short statutes of limitations, frequently one to two years
Real-World Example
A local restaurant owner posts on social media that a competing chef "served spoiled meat that put customers in the hospital," knowing the claim is fabricated. The statement is a false assertion of fact (not opinion), it is published to many readers, and it plainly harms the competitor's professional reputation. If the targeted chef is a private individual, they would typically need to show the poster was at least negligent—here, clearly satisfied—and could recover for the lost business and reputational damage.
Now suppose a newspaper columnist writes that a mayor "is, in my view, the worst leader this city has ever had." That is an expression of opinion, not a provable false fact, so it is not defamatory. And because the mayor is a public official, even a false factual claim about the mayor would require proof of actual malice—that the columnist knew it was false or acted with reckless disregard for the truth. These contrasts show how the plaintiff's status and the nature of the statement shape the outcome.
Fault Standards and Key Concepts
| Concept | Who/What It Applies To | What Must Be Shown |
|---|---|---|
| Negligence Standard | Private individuals (in most states) | Speaker failed to use reasonable care about the truth |
| Actual Malice | Public officials and public figures | Knowledge of falsity or reckless disregard for the truth |
| Libel | Written, printed, online, or broadcast statements | A false, defamatory statement in lasting form |
| Slander | Spoken statements | A false, defamatory spoken statement; may need special damages |
| Slander Per Se | Especially harmful categories of spoken statements | Harm often presumed (e.g., accusing of a crime or professional misconduct) |
The Actual Malice Standard and Common Defenses
One of the most important rules in defamation law is the actual malice standard. Under the landmark constitutional framework, public officials and public figures cannot win a defamation claim merely by proving a statement was false and damaging. They must prove, with convincing clarity, that the defendant made the statement knowing it was false or with reckless disregard for whether it was true—a deliberately demanding test designed to give "breathing space" to robust debate about public affairs. Private individuals, by contrast, generally need only show the speaker was negligent about the truth, though states set their own rules, and a private plaintiff usually must prove actual malice to recover presumed or punitive damages on matters of public concern.
Several defenses can defeat a defamation claim regardless of the plaintiff's status. Truth (substantial truth) is a complete defense. Opinion that cannot be proven true or false is protected, as are rhetorical hyperbole and name-calling. Certain communications are privileged: absolute privilege protects statements made in judicial, legislative, and some official proceedings, while qualified privilege protects good-faith statements made in appropriate circumstances, such as a former employer giving a measured reference, unless abused. Consent is also a defense. State law varies on the elements, the categories of "per se" defamation, retraction statutes, and the increasingly common anti-SLAPP laws that allow early dismissal of suits aimed at silencing protected speech.

Defamation law is technical, fact-intensive, and heavily shaped by free-speech protections, so early legal guidance is valuable. Consider consulting an attorney if:
- A false factual statement about you was published and harmed your reputation or livelihood
- You are unsure whether you would be treated as a private individual or public figure
- You received a cease-and-desist letter or are being sued for something you said or wrote
- The statements appeared online and you need to identify an anonymous source
- You are concerned about a fast-approaching filing deadline

Frequently Asked Questions
What is defamation?
Defamation is a false statement of fact, communicated to someone other than the person it is about, that harms that person's reputation. It includes libel, which is written or otherwise recorded, and slander, which is spoken. To be defamatory, a statement must generally be a false assertion of fact rather than an opinion, and it must be published to at least one third party and cause reputational harm.
What is the difference between libel and slander?
Libel is defamation in a fixed, lasting form, such as writing, print, online posts, or broadcasts. Slander is defamation in a transitory, spoken form. Historically, libel was treated as more serious because it is permanent and can reach a wider audience, and some slander claims required proof of special damages while certain categories of slander were considered so harmful they were actionable without that proof.
What does a public figure have to prove in a defamation case?
Public officials and public figures must prove actual malice, meaning the defendant made the false statement knowing it was false or with reckless disregard for whether it was true or false. This demanding standard comes from constitutional free-speech protections and is much harder to meet than the ordinary negligence standard that typically applies to private individuals.
Is truth a defense to defamation?
Yes. Truth is generally a complete defense to defamation, because a defamation claim requires a false statement of fact. If the statement is substantially true, it cannot be defamatory no matter how damaging it is. Other defenses include statements of pure opinion, privileged statements such as testimony in court, and consent by the person the statement is about.
Is calling someone a name defamation?
Usually not. Insults, name-calling, hyperbole, and statements of pure opinion are generally not defamatory because they are not provably false statements of fact. Defamation requires a false factual assertion that can be proven true or false. Saying someone is a terrible person is opinion, while falsely stating that they committed a specific crime can be defamatory.
Deadlines Are Short
Defamation often carries one of the shortest statutes of limitations of any claim, frequently just one to two years. See the deadlines in our state-by-state statute of limitations guide and act promptly.
