Definition
Animus defamandi is a Latin phrase meaning "the intention to defame." It refers to the mental state of a speaker or publisher who communicates a false and injurious statement with the deliberate purpose of damaging another person's reputation. In defamation law, it describes the specific intent element — the conscious desire to harm the subject's reputation — as distinguished from mere carelessness, misunderstanding, or good-faith error.
The concept functions as the subjective face of what Anglo-American law has historically called "malice" in defamation: not hatred or ill-will in the popular sense, but a purposeful orientation toward reputational injury. Whether animus defamandi must be proven, and what suffices to establish it, has shifted considerably as defamation doctrine evolved from a predominantly common-law regime to one shaped by constitutional limits on liability.

Common Confusion
Animus defamandi is closely related to — but not identical to — the "actual malice" standard established in constitutional defamation doctrine. Actual malice, as that term is used in the modern constitutional sense, means knowledge of falsity or reckless disregard for truth or falsity. Animus defamandi, by contrast, focuses specifically on intent to injure reputation, not on the speaker's state of mind regarding the truth of the statement. A speaker could publish a false statement recklessly without specifically intending reputational harm; conversely, a speaker could intend to injure reputation while genuinely (if incorrectly) believing the statement to be true. The two concepts overlap but are analytically distinct. Researchers working with pre-twentieth-century sources will encounter animus defamandi in contexts where "malice" is used loosely, and should not assume it maps cleanly onto the constitutional actual malice standard.

Why It Matters in Research
This term appears almost exclusively in common-law treatises and older legal dictionaries rather than in modern American case law, where it has been largely displaced by the constitutional vocabulary of "actual malice" and "fault." Researchers using Law Mind corpus materials spanning the nineteenth and early twentieth centuries will encounter animus defamandi as a live doctrinal term, particularly in English and early American authorities on libel and slander. Understanding its historical function is essential for reading those sources accurately.
A key research trap: historical sources frequently conflate animus defamandi with "legal malice" or "express malice," using the terms interchangeably or in overlapping ways. This can obscure meaningful distinctions between intent-based and knowledge-based theories of liability. When a historical source says malice is "presumed" from the publication of defamatory words, that presumption was doing work precisely because animus defamandi — actual proof of defamatory intent — was difficult to establish directly. The shift toward requiring affirmative proof of fault in modern constitutional doctrine represents, in part, a rejection of that presumption regime.
Researchers studying qualified privilege doctrine will find animus defamandi particularly important. Under qualified privilege, a defamatory statement made on a privileged occasion (such as an employment reference or a report to a law enforcement authority) is protected unless the plaintiff can demonstrate that the defendant acted with animus defamandi — that is, that the dominant motive was reputational injury rather than legitimate communication. This use of the term persists in some Commonwealth jurisdictions and in older American treatises on privilege.

Historical Dictionary Support
Black's Law Dictionary defines animus defamandi as "the intention of defaming," describing it as "the malicious intent which is essential in every case of verbal injury to render it the subject of an action for libel or slander." This formulation reflects the classical common-law position: intent to defame was a core element of actionable defamation, and the term named that element precisely.
What Black's does not capture — and what no nineteenth-century dictionary fully addresses — is the doctrinal tension the concept contained. The common law simultaneously required animus defamandi as a theoretical matter and then largely presumed it from the act of publication, effectively rendering the intent element vestigial in most cases. Historical sources that state intent is "essential" should therefore be read with awareness that courts rarely demanded direct proof of it. The gap between the formal requirement and the evidentiary reality is a recurring feature of pre-modern defamation doctrine.
No significant divergence exists among the historical dictionary sources on the core meaning of this term. The entry is consistent across the available authorities. The more significant evolution is not in the dictionary definitions but in the case law that progressively displaced the term's practical relevance.

Jurisdictional Note
In American law, animus defamandi as a freestanding doctrinal requirement has been substantially absorbed into, or superseded by, the fault standards mandated by constitutional doctrine since the latter half of the twentieth century. The term retains greater currency in English, Australian, and Canadian defamation scholarship, where the common-law tradition has not been as thoroughly displaced by constitutional overlay.
