Pessoa jurídica é legal person ou legal entity. Este é o termo mais usado em inglês.
Esta é a definição de legal person na Wikipédia:
A legal person in legal context typically is a person (or less ambiguously, a legal entity)1—whether human or non-human—that is recognized as having certain privileges and obligations such as the legal capacity to enter into contracts, to sue, and to be sued.
However, the term "legal person" is ambiguous because it is often used as a synonym of terms that refer only to non-human legal entities, specifically in contradistinction to "natural person".
So there are of two kinds of legal entities, human and non-human: natural persons (also called physical persons) and juridical persons—also called juridic, juristic, artificial, legal, or fictitious persons, Latin: persona ficta—which are entities such as a corporation, firm, business or non-business group, or government agency, etc., that are treated in law as if they were persons.
Pessoa física é natural person or physical person:
In jurisprudence, a natural person is a person (in legal meaning, i.e., one who has its own legal personality) that is an individual human being, as opposed to a legal person, which may be a private (i.e., business entity or non-governmental organization) or public (i.e., government) organization. Historically, a human being was not necessarily a natural person in some jurisdictions where slavery existed (subject of a property right) rather than a person.
