A public procurator () is an officer of a state charged with both the investigation and prosecution of crime. The office is a feature of a civil law inquisitorial rather than common law adversarial system. Countries such as Japan, China, Russia, Indonesia and Lithuania adopt the procuratorial system.
The office of a procurator is called a procuracy or procuratorate. The terms are from Latin and originate with the procurators of the Roman Empire.
