Delict (from Latin dēlictum, past participle of dēlinquere ‘to be at fault, offend’) is a term in civil and mixed law jurisdictions whose exact meaning varies from jurisdiction to jurisdiction but is always centered on the notion of wrongful conduct.

In Scots and Roman Dutch law, it always refers to a tort, which can be defined as a civil wrong consisting of an intentional or negligent breach of duty of care that inflicts loss or harm and which triggers legal liability for the wrongdoer. Other civil wrongs include breach of contract and breach of trust. Liability is imposed on the basis of moral responsibility, i.e. a duty of care or to act, and fault (culpa) is the main element of liability. The term is similarly used in a handful of other English speaking jurisdictions which derive their private law from French or Spanish law, such as Louisiana and the Philippines, but tort is the equivalent legal term used in common law jurisdictions and in general discussions of non-contractual liability (for instance, Wikipedia has an article on European tort law rather than “European law of delict”, since tort is the generally understood term in comparative international law, and a page on Tort Law in China rather than “law of delict in China”).

In Spanish law, delito is any breach of criminal law, i.e. a criminal offence. In Italian law, delitto penale is the same concept, but illecito civile extracontrattuale (or delitto civile), like delict in Scots law, is an intentional or negligent act which gives rise to a legal obligation between parties even though there has been no contract between them, akin to common-law tort. German-speaking countries use the word Delikt for crime and unerlaubte Handlung for delict, but Deliktsrecht is a branch of civil law (similar to tort law). In French law, délit penal is a misdemeanor (between contravention ‘petty offence’ and crime ‘felony; major indictable offence’), while délit civil, again, is a tort. Because of this, French law prefers to speak in terms of responsabilité civile (‘civil liability’). In the canon law of the Catholic Church, a delict is a crime.
