Definition
An award of damages equal to three times the amount of actual damages found by the trier of fact. Treble damages are a creature of statute — they do not exist at common law and cannot be awarded absent express legislative authorization. The typical mechanism is straightforward: the jury determines the underlying compensatory amount, and the court then multiplies that figure by three, either automatically by operation of the statute or upon motion of the prevailing party.
Treble damages serve a dual purpose that distinguishes them from purely compensatory remedies. They punish wrongful conduct and deter future violations, functioning similarly to punitive damages, but with a fixed multiplier set by the legislature rather than left to jury discretion.
The most consequential modern applications arise under federal statutes. The Sherman Antitrust Act and the Clayton Act mandate treble damages for successful private antitrust plaintiffs. The Racketeer Influenced and Corrupt Organizations Act (RICO) similarly provides for treble damages in civil actions. Patent infringement, certain copyright claims, and trade secret misappropriation under the Defend Trade Secrets Act also permit trebling, though in some of these contexts the award is discretionary rather than automatic.

Common Language
Modern common usage (Wiktionary): "Treble" as an adjective means three times as great or as many; triple.
Historical common usage (Webster's 1913): "Treble: Threefold; triple." Also used in music to denote the highest vocal or instrumental part.
The common meaning and the legal meaning are not far apart — "treble" plainly signals multiplication by three in both registers. The meaningful gap is not semantic but structural: in ordinary usage, trebling is a neutral descriptive act. In law, treble damages are a specific statutory remedy carrying significant procedural and constitutional implications. A researcher encountering the word "triple" in a historical legal document should not assume it means the same thing as the formal term of art "treble damages," which carries its own body of doctrine about when courts may and must apply the multiplier.

Common Confusion
Treble damages are frequently conflated with punitive damages, but the two are doctrinally distinct. Punitive damages are assessed by the jury based on the defendant's culpability and the need for deterrence, with the amount largely discretionary (subject to constitutional due process limits). Treble damages are imposed by the court as a statutory multiplier applied to the compensatory base — the legislature has already set the ratio. Some courts have held that where a statute provides for treble damages, a separate punitive damages award may be inappropriate or duplicative. The distinction matters in research because constitutional due process constraints on excessive punitive damages (as developed in BMW of North America, Inc. v. Gore and its progeny) do not apply to statutory treble damage awards in the same way.
Do not confuse treble damages with double damages, which appear in a distinct set of statutes (including certain provisions of the Fair Labor Standards Act for willful wage violations) and carry their own separate body of case law.

Why It Matters in Research
The most important navigational point: treble damages always require a statutory anchor. When researching a treble damages claim, the first question is always which statute authorizes the award, because the scope, conditions, and whether the multiplier is mandatory or discretionary all vary by statute. A researcher who locates a treble damages award in case law without tracing it to the governing statute is missing the controlling authority.
Historically, treble damages statutes were common in English law well before American independence — the Statute of Treble Damages (1278) and various subsequent English statutes used trebling as a standard penalty mechanism. Researchers working in early American state materials will encounter treble damages in contexts that have since been repealed or superseded, including timber trespass, certain debt actions, and hunting and fishing violations. The presence of treble damages language in a historical source does not mean that remedy survives in modern law.
In federal antitrust research, the mandatory nature of treble damages under the Clayton Act is a defining feature of the private enforcement scheme — courts have consistently held they have no discretion to reduce the award below the trebled amount once liability and actual damages are established. This distinguishes antitrust trebling from the discretionary trebling available under the Defend Trade Secrets Act and some patent infringement provisions.
For intellectual property researchers, the trade secret context is particularly active: exemplary damages under the DTSA are capped at two times actual damages, which means they do not technically reach "treble" — a precision point that matters when comparing federal and state trade secret remedies.
The corpus will contain treble damages discussions scattered across antitrust, IP, RICO, and tort materials. Cross-referencing across those subject areas is essential to understanding how courts have treated the punitive-versus-compensatory character of treble awards.

Historical Dictionary Support
Black's Law Dictionary (both editions) and Burrill's Law Dictionary converge on the same functional definition: damages given by statute in certain cases, consisting of the single damages found by the jury, trebled by the court on motion. This procedural detail — jury finds the base, court trebles — is the traditional mechanism and remains the standard approach. Black's cites Tidd's Practice (2 Tidd, Pr. 893, 894) for the proposition, grounding the definition in English procedural practice.
Bouvier's offers no independent definition, redirecting to "Measure," which reflects Bouvier's organizational tendency to consolidate damages discussion rather than give each subcategory its own entry. Researchers using Bouvier's for treble damages should expect to work through the broader damages entry.
What the historical dictionaries uniformly omit is the constitutional dimension that modern doctrine has developed. Questions about whether treble damages constitute a "penalty" subject to Eighth Amendment excessive fines analysis, or how they interact with due process limits on punitive awards, are entirely absent from these sources — which is unsurprising given their era, but is a significant gap for modern researchers relying on historical sources to frame current arguments.

Jurisdictional Note
State treble damages statutes vary substantially. Many states have consumer protection acts, antitrust statutes, and unfair trade practices laws that incorporate treble damages, but the triggering conditions, whether the multiplier is mandatory or discretionary, and whether attorney's fees are bundled with the award differ considerably by jurisdiction. Researchers should not assume that federal antitrust trebling doctrine maps cleanly onto state statutory analogues.
