Definition
A natural person is a human being recognized by law as having legal personality — the capacity to hold rights, bear duties, enter contracts, sue and be sued, own property, and otherwise participate in legal relations. The term exists primarily to draw a distinction: where law also recognizes artificial persons (corporations, government entities, and other legal constructs created by statute or charter), "natural person" supplies the vocabulary for the human counterpart.
The concept is foundational rather than technical. A natural person's legal personality generally attaches at birth and ends at death, though specific rules — concerning prenatal rights, posthumous interests, or legal incapacity — vary by jurisdiction and context. Capacity to exercise legal rights (as distinct from the mere possession of them) may be modified by age, mental competency, incarceration, or other conditions recognized by law.

Common Language
Modern common usage (Wiktionary): Plural of "natural person" — a human being as a legal subject, as opposed to a legal fiction such as a corporation.
Historical common usage (Webster's 1913): Webster's 1913 does not carry a standalone entry for "natural person," reflecting that the phrase was treated as a term of art rather than ordinary vocabulary in that period.
The gap here is one of context, not conflict. In everyday speech, "person" already means a human being, so "natural person" sounds redundant. In law, the modifier is load-bearing: it signals that the speaker is operating in a framework where non-human entities also qualify as persons, and the word "natural" is doing the work of exclusion.

Common Confusion
NATURAL PERSON vs. LEGAL PERSON (ARTIFICIAL PERSON): These terms are correlatives, not synonyms. A legal or artificial person — a corporation, LLC, trust, or governmental body — possesses legal personality by operation of law, not by virtue of being human. The distinction matters because legal persons may enjoy some rights natural persons hold (e.g., the right to contract, to own property, to sue) while being excluded from others (e.g., constitutional protections tied explicitly to citizenship or humanity). Researchers working in corporate law, constitutional rights, or international human rights must be precise about which category their source is addressing.
NATURAL PERSON vs. CITIZEN: Not all natural persons are citizens of any given jurisdiction, and citizenship attaches a distinct bundle of rights and obligations beyond bare legal personality. A non-citizen human being present in a jurisdiction is still a natural person for most legal purposes.

Why It Matters in Research
The phrase "natural person" is a signal term. When a constitution, statute, regulation, or contract uses it instead of the unqualified word "person," the drafter is deliberately excluding corporations and other artificial persons from the provision's scope — or, conversely, making clear that only humans are covered. Researchers must therefore read the surrounding instrument carefully: using "person" alone may or may not include artificial persons depending on context, jurisdiction, and applicable definitional rules (including statutory definitions sections).
In historical sources, the distinction between natural and artificial persons carried significant freight in debates over corporate rights — particularly in nineteenth- and early twentieth-century American law — as courts and legislatures worked through whether constitutional protections extended to corporations. Researchers consulting historical materials on that question will encounter "natural person" as a term of limitation.
In international law and human rights instruments, "natural person" often delimits the class of rights-holders, distinguishing individual human rights from the rights of states or corporate actors. The same care applies when reading EU regulations (which frequently use "natural person" as a defined term) alongside American materials.
Corpus researchers should also note: older sources may assume the natural/artificial distinction without naming it, referring simply to "persons" in contexts where only humans were legally imaginable. The explicit "natural person" formulation becomes more common as artificial persons become more legally significant and the need for precision increases.

Historical Dictionary Support
Black's Law Dictionary defines natural persons as those "formed by nature, as distinguished from artificial persons, or corporations, formed by human laws for purposes of society and government," attributing the formulation to Wharton. This is a compact but accurate statement of the classical position: the distinction is between the given (human beings) and the constructed (legal entities created by law).
Bouvier's Law Dictionary directs readers to the entry for "PERSON," a cross-reference that itself signals how central the natural/artificial person distinction was to Bouvier's organizational scheme — legal personality was treated as the master concept, with natural and artificial persons as its two principal species.
Neither historical dictionary engages with contested edges: the legal status of persons before birth or after death, the treatment of persons under legal disability, or the complications that arise when statutes assign "natural person" a specific defined meaning that may deviate from the common law baseline. Researchers should not assume the historical entries resolve those questions.

Jurisdictional Note
Most common law and civil law jurisdictions recognize the natural/artificial person distinction in substantially the same terms, but the legal consequences of that distinction — particularly regarding constitutional rights, tax treatment, and regulatory obligations — vary considerably. In the United States, the question of which constitutional protections attach to natural persons only (versus also to corporations) remains actively litigated. In the European Union, "natural person" is a frequently defined term in regulatory instruments, including data protection law, where the definition shapes the entire scope of individual rights.
