Yes, it is illegal to harass someone. Every state treats harassment as a crime, and federal law adds its own penalties when the conduct crosses state lines or uses phones, the internet, or the mail. Depending on what the harasser did and how far it went, consequences range from a misdemeanor fine to decades in federal prison, and the victim can separately sue for money damages in civil court.
What the Law Treats as Harassment
Harassment is not a single rude moment. Courts look for a pattern of conduct aimed at a specific person that shows a clear purpose to alarm, annoy, or threaten. One nasty comment or an isolated argument almost never qualifies. What turns conduct criminal is repetition combined with intent: the person keeps doing it, and they mean to cause distress or fear.
Judges apply a “reasonable person” standard. The question isn’t whether the particular victim is unusually sensitive, but whether an ordinary person in the same situation would feel genuinely threatened or distressed. Courts also ask whether the conduct serves a legitimate purpose. A debt collector calling about a real debt, a supervisor delivering critical feedback, or a reporter asking uncomfortable questions may be unwelcome, but each has a recognized reason for the contact and generally won’t be treated as harassment.
The proof required depends on whether the case is criminal or civil. A criminal prosecution must prove guilt beyond a reasonable doubt, the highest standard in American law. A civil lawsuit only needs to show harassment was more likely than not, a lower bar called preponderance of the evidence. That gap is why someone acquitted of a harassment charge can still lose a civil case over the same conduct.
When Speech Becomes Criminal
The First Amendment protects a wide range of speech, including speech that is offensive or deeply unpopular. It does not protect true threats of violence, incitement to imminent lawless action, or a targeted pattern of harassment.
In Counterman v. Colorado (2023), the Supreme Court held that prosecutors pursuing a true-threat case must show the speaker acted with at least recklessness, meaning they consciously disregarded a substantial risk that their words would be perceived as threatening violence. The speaker doesn’t have to intend to carry out the threat, but a conviction can’t rest on words the speaker genuinely didn’t realize sounded threatening.1Supreme Court of the United States. Counterman v. Colorado, No. 22-138
That rule draws a working line between being obnoxious and being criminal. Insulting someone on social media is usually protected, even when it’s cruel. Repeatedly messaging someone that you know where they live and describing what you plan to do to them is not. The distinction turns on whether a reasonable person would fear for their safety and whether the speaker was at least reckless about that effect.
Criminal Penalties
Most states charge a first harassment offense as a misdemeanor, with possible penalties including up to a year in jail, fines, probation, and mandatory counseling. When the conduct escalates to credible threats of violence, violations of existing court orders, or sustained targeting of the same victim, charges often rise to felony-level offenses like aggravated harassment or stalking. Felony convictions carry multi-year prison sentences and substantially higher fines.
Federal law reaches harassment that crosses state lines or uses interstate tools like the internet, phone networks, or the mail. Under 18 U.S.C. § 2261A, it is a federal crime to stalk someone by traveling across state borders or using electronic communications with intent to harass, intimidate, or place another person in reasonable fear of death or serious injury.2Office of the Law Revision Counsel. 18 U.S.C. 2261A – Stalking Federal stalking penalties scale with the harm caused: up to five years in prison in a standard case, up to ten years if the offender uses a dangerous weapon or causes serious bodily injury, up to twenty years for life-threatening injuries, and life imprisonment if the victim dies.3Office of the Law Revision Counsel. 18 U.S.C. 2261 – Interstate Domestic Violence
Stalking someone while also violating a protective order carries a mandatory federal minimum of one year in prison, with no fully suspended sentence available.3Office of the Law Revision Counsel. 18 U.S.C. 2261 – Interstate Domestic Violence
Online Harassment and Cyberstalking
Digital harassment is prosecuted the same way as in-person conduct, and it often leaves a cleaner evidentiary trail. Cyberstalking, doxing (publicly releasing someone’s private information), and repeated threatening messages through social media, email, or text are all prosecutable under state and federal law.
Under 18 U.S.C. § 875, transmitting a threat to kidnap or injure someone through interstate communications is a federal crime punishable by up to five years in prison.4Office of the Law Revision Counsel. 18 U.S. Code 875 – Interstate Communications Because most internet traffic crosses state lines, the statute reaches the vast majority of online threats. The federal stalking statute separately covers electronic communications used in a course of conduct that places another person in reasonable fear of serious harm or causes substantial emotional distress.2Office of the Law Revision Counsel. 18 U.S.C. 2261A – Stalking
Swatting, the practice of calling in a fake emergency to trigger an armed police response at a victim’s home, is prosecuted under 18 U.S.C. § 1038. Conveying false information about an emergency carries up to five years in federal prison. If someone is seriously injured during the response, that jumps to twenty years. If someone dies, the sentence can be life.5Office of the Law Revision Counsel. 18 U.S.C. 1038 – False Information and Hoaxes
Anonymity online complicates investigations but rarely holds up long. IP addresses, account metadata, and platform records regularly let law enforcement identify harassers, and most state statutes now define harassment to include persistent electronic contact regardless of physical proximity.
Civil Lawsuits for Harassment
Criminal prosecution isn’t the only path. Victims can bring their own civil lawsuits for money damages, with the victim acting as plaintiff and no need for government involvement.
The most common legal theory is intentional infliction of emotional distress. The plaintiff must show the harasser’s conduct was extreme and outrageous, beyond what civilized society tolerates, and that it caused real emotional harm. Medical records, therapist notes, and evidence of disrupted daily life such as missed work or sleep problems help build that case. Invasion of privacy is another common theory, covering conduct like surveillance, doxing, and repeated intrusion into private spaces.
Because civil cases use the lower preponderance standard, some victims who couldn’t secure a criminal conviction still prevail in civil court. Successful plaintiffs can recover medical expenses, lost wages, emotional suffering, and punitive damages aimed at punishing particularly egregious behavior. Awards vary widely with the severity and duration of the conduct.
Workplace Harassment Is a Separate Framework
Harassment at work is handled under its own federal regime, not the general criminal harassment statutes. Title VII of the Civil Rights Act of 1964, enforced by the Equal Employment Opportunity Commission, is the main federal law.6U.S. Equal Employment Opportunity Commission. Title VII of the Civil Rights Act of 1964 For workplace harassment to be illegal under Title VII, the conduct must target a protected characteristic: race, color, religion, sex, or national origin. Other federal laws extend coverage to disability and age. General rudeness or personality clashes that don’t involve a protected characteristic aren’t covered.
Title VII caps combined compensatory and punitive damages based on employer size: $50,000 for employers with 15 to 100 employees, $100,000 for those with 101 to 200, $200,000 for 201 to 500, and $300,000 for employers with more than 500 employees.7Office of the Law Revision Counsel. 42 U.S. Code 1981a – Damages in Cases of Intentional Discrimination Back pay, front pay, and attorney fees sit outside those caps.
Deadlines are strict. You generally have 180 calendar days from the last harassing incident to file a charge with the EEOC, extended to 300 days in states with their own employment-discrimination agency. Federal employees get only 45 days to contact their agency’s EEO counselor.8U.S. Equal Employment Opportunity Commission. Time Limits for Filing a Charge Missing those windows can permanently bar the claim.
Protective Orders and the Cost of Violating One
When harassment is ongoing, a protective order (also called a restraining order in some jurisdictions) can set enforceable limits. These orders typically require the harasser to stay a specified distance from the victim’s home, workplace, and person, and they prohibit any contact, whether direct, electronic, or through a third party.
The process usually starts with a temporary or ex parte order, which a judge can issue the same day based on the victim’s petition if there’s evidence of immediate danger. The harasser is then served and given a chance to respond at a full hearing, typically within about two weeks. If the judge finds continued risk, a longer-term order follows, often lasting one to five years, with renewal available in many jurisdictions if the threat persists.
Violating a protective order is a separate criminal offense. Law enforcement can arrest someone who breaches the order’s terms without needing a new warrant. A first violation is usually charged as a misdemeanor with mandatory confinement in most jurisdictions, and repeat violations escalate to felonies with longer mandatory sentences. The federal mandatory minimum of one year applies when the violation accompanies stalking.3Office of the Law Revision Counsel. 18 U.S.C. 2261 – Interstate Domestic Violence
If You’re Being Harassed, Build the Record
Strong evidence is what separates a harassment claim that moves forward from one that stalls. Start documenting before you file a police report or call a lawyer.
Keep a detailed log of every incident: date, time, location, what happened, what was said, and the names of any witnesses. A notebook or notes app is fine. Consistency and detail are what matter. A single text may look innocuous in isolation; fifty of them over two months tells a different story.
For digital harassment, preserve the evidence before you block the person. Blocking often removes messages or posts from your view. Screenshot every threatening message, post, or email, and capture the sender’s username, profile URL, the platform, and the timestamp. Save the files in a separate folder so you don’t have to keep looking at the content. Courts in some areas have specific rules about authenticating digital evidence, so a lawyer in your jurisdiction can tell you what will hold up.
When you’re ready to report, use the local police department’s non-emergency line for incidents that aren’t an immediate danger. Many departments now take online reports for harassment where no one was physically injured and no suspect is immediately identifiable. Keep the report number you receive; you’ll need it for protective order petitions and any court proceedings. Filing a false police report is itself a crime, so stick to what you can document.
Defenses and False Accusations
Not every harassment accusation holds up. The most common defense is that the conduct was constitutionally protected speech. The First Amendment covers even offensive expression as long as it doesn’t rise to a true threat or a targeted course of harassing conduct. Political arguments, isolated heated exchanges, and rude remarks generally fall on the protected side.
Legitimate purpose is another defense. A landlord sending repeated lease-violation notices, a creditor calling about an unpaid debt, or a reporter asking uncomfortable questions all have recognized reasons for the contact, and courts won’t treat purpose-driven communication as harassment just because it’s unwelcome.
Lack of pattern also defeats many cases. Because most harassment statutes require a course of conduct, meaning two or more acts showing continuity of purpose, a single incident rarely meets the definition. The accused can also argue the conduct wouldn’t alarm a reasonable person, which defeats the objective element most statutes require.
Filing a knowingly false harassment report carries its own consequences. Most states treat false police reports as a misdemeanor with possible jail time and fines, and a person falsely accused may have grounds for a civil defamation or malicious prosecution claim against the accuser.
