Extraordinary rendition is a euphemism for state-sponsored kidnapping in another jurisdiction and transfer to a third state. The phrase usually refers to a United States-led program used during the War on Terror, which had the purpose of circumventing the source country's laws on interrogation, detention, extradition and/or torture. Extraordinary rendition is a type of extraterritorial abduction, but not all extraterritorial abductions include transfer to a third country.

Interrogation is interviewing as commonly employed by law enforcement officers, military personnel, intelligence agencies, organized crime syndicates, and terrorist organizations with the goal of eliciting useful information, particularly information related to suspected crime. Interrogation may involve a diverse array of techniques, ranging from developing a rapport with the subject to torture.
