In the field of counterintelligence, a double agent (also double secret agent) is an employee of a secret intelligence service, whose primary purpose is to spy on a different target organization, but who, in fact, is a member of the at target organization.

Double agentry may be practiced by spies of the target organization who infiltrate the controlling organization, or may result from the turning (switching sides) of previously loyal agents of the controlling organization by the target. The threat of execution is the most common method of turning a captured agent (working for an intelligence service) into a double agent (working for a foreign intelligence service) or a double agent into a re-doubled agent. It is unlike a defector, who is not considered an agent as agents are in place to function for an intelligence service and defectors are not, but some consider that defectors in place are agents until they have defected.

Double agents are often used to transmit disinformation or to identify other agents as part of counter-espionage operations. They are often very trusted by the controlling organization since the target organization will give them true, but useless or even counterproductive, information to pass along.

Double agents[edit]

Some people listed here are not true double agents (as defined above), but rather (single) agents working as a mole within an intelligence organization.

Pre-twentieth century[edit]

World War I[edit]

  • Mata Hari (stage name for Margaretha Geertruida "Grietje" Zelle)

World War II[edit]

Cold War[edit]


  • Denis Donaldson, infiltrated the Sinn Féin on behalf the British government. He was found dead in his cottage after a Northern Ireland newspaper revealed this.
  • Kevin Fulton (real name Peter Keeley), infiltrated the IRA for British Intelligence. He was allegedly betrayed by his employers and nearly sacrificed to cement Stakeknife's cover in the IRA (see below).
  • Freddie Scappaticci ("Stakeknife"), infiltrated the IRA for British Intelligence. Allegedly, the British government ordered him to expose Fulton to increase his own standing in the IRA.
  • Robert Nairac, British Military Intelligence agent who sometimes went undercover in the IRA. Killed in 1977.


  • April Fool, allegedly an American officer who provided false information to Saddam Hussein.
  • Iyman Faris, worked for the FBI, but was loyal to Al-Qaeda.
  • Mikel Lejarza ("El Lobo"), Spanish agent working for the Basque separatist ETA.
  • Katrina Leung, worked for both China and the FBI.
  • Ashraf Marwan, an Egyptian businessman and an alleged spy for Israel, or possibly an Egyptian double agent. Managed to become celebrated as a hero in each country for his alleged work against the other.

Re-doubled agent[edit]

A re-doubled agent is an agent who gets caught as a double agent and is forced to mislead the foreign intelligence service.

F. M. Begoum describes the redoubled agent as "one whose duplicity in doubling for another service has been detected by his original sponsor and who has been persuaded to reverse his affections again".[1]

Triple agent[edit]

A triple agent pretends to be a double agent for one side, while he or she is truly a double agent for the other side. Famous triple agents include Eddie Chapman, Kim Philby and Alexander Litvinenko.

A lesser used definition of triple agent is an agent who works for three intelligence services, but is usually truly loyal to only one of them.
