A sleeper agent is a spy who is placed in a target country or organization, not to undertake an immediate mission, but rather to act as a potential asset if activated. Sleeper agents are popular plot devices in fiction, in particular espionage fiction and science fiction.
Sleeper agents in espionage
In espionage, a sleeper agent is one who has infiltrated into the target country and has "gone to sleep", sometimes for many years. That is, he or she does nothing to communicate with his or her sponsor nor any existing agents, nor to obtain information beyond that in public sources. They can also be referred to as 'deep cover' agents. They acquire jobs and identities—ideally ones which will prove useful in the future - and attempt to blend into everyday life as normal citizens. Counter-espionage agencies in the target country cannot, in practice, closely watch all of those who might possibly have been recruited some time before.
In a sense, the best sleeper agents are those who do not need to be paid by the sponsor as they are able to earn enough money to finance themselves. This avoids any possibly traceable payments from abroad. In such cases, it is possible that the sleeper agent might be successful enough to become what is sometimes termed an "agent of influence".
Sleeper agents who have been discovered have often been natives of the target country who moved elsewhere in early life and were co-opted (perhaps for ideological or ethnic reasons) before returning to the target country. This is valuable to the sponsor as the sleeper's language and other skills can be those of a 'native' and thus less likely to trigger suspicion.
Choosing and inserting sleeper agents has often posed difficulties as it is uncertain which target will be appropriate some years in the future. If the sponsor government (or its policies) change after the sleeper has been inserted, the sleeper might be found to have been planted in the wrong target.
- Otto Kuehn and family were installed in Hawaii by the German Abwehr, before World War II, to work for Japanese intelligence. Kuehn, and his family, aided the Japanese in the period before the Attack on Pearl Harbor.
- Kim Philby was recruited by the Soviets while at university and may have been a sleeper agent for some years until going to work for the British government. By the end of WWII, he was operating as the liaison between the British Secret Intelligence Service and several U.S. intelligence operations. He was an agent of influence by then, but had not been a sleeper agent for several years.
- The so-called Illegals Program is an alleged network of sleeper spies planted in the U.S. by the Russian Foreign Intelligence Service. The ongoing, multi-year investigation culminated in June 2010 with the filing of charges and the arrest of 10 suspects in the U.S. and another in Cyprus. Russian General Directorate for special programs or GUSP in Russian transliteration (Главное управление специальных программ, ГУСП) still recruits candidates among students and talented scientists in order to use them as sleeper agents or as legal employees in the Police and intelligence bodies in Russian Federation.
Fictional sleeper agents
In fiction, particularly science fiction, sleeper agents fall into two categories. The first is an extension of the real world sleeper agent where an enemy agent is substituted for a person already in a trusted position. The second and more common category involve people who have been subjected to mind control techniques, such as drugs, torture, psychological conditioning, implanted devices, and even telepathic manipulation who then are either released, or allowed to escape back to friendly territory. These sleeper agents are then used by enemy forces to spy, to conduct sabotage, to assassinate certain targets, or for other operations the enemy has in mind for them. During these outbreaks, the sleeper agent doesn't normally know what he/she is doing.
The substitution sleeper agent was often surgically altered to appear as someone else but more recent versions tend toward androids or clones. Or the agent may have been an infiltrator from the start but brainwashed to believe they are the real thing until activation.
Activation of the second kind of sleeper is, at least in novels and stories, done by approaching the agent and uttering a long ago memorized password or pass phrase, or by mailing a postcard with a significant picture to the sleeper. Once a sleeper becomes active, counter intelligence agencies can, at least in principle, become aware of the sleeper as intelligence is collected and transmitted, as instructions are passed, and so on.
In popular culture
There are a number of examples of sleeper agents found in science fiction and other forms of entertainment. Many times the unveiling of a sleeper agent is an important part of the plot and acts as surprise element and a plot twist. Some examples of sleeper agents include:
- One of the earlier uses of the second type of sleeper agents in fiction is in Richard Condon's 1959 novel, The Manchurian Candidate, which has twice been adapted to film. Both the original and the remake are about a group of people 'programmed' to be sleeper agents. One of the sleeper agents is part of a Presidential election campaign, which if won will produce a Vice President controlled by sinister forces. One of his fellows would then be ordered to assassinate the President, allowing these forces to control the Executive Branch of Government.
- Another early use of sleeper agents is in the 1977 Charles Bronson film "Telefon." Bronson plays an unwitting KGB agent whose trigger phrase is borrowed from Robert Frost's poem, "Stopping by Woods on a Snowy Evening."

Faber discovers the true nature of Operation Fortitude and tries to get the information to his home country.
