Sleeper agents are spies who are placed in a target country or organization, not to undertake an immediate mission, but rather to act as potential assets if activated at a later point in time.
Sleeper agents are popular plot devices in fiction, in particular espionage fiction and science fiction.

In espionage, a sleeper agent is one who has infiltrated into the target country and 'gone to sleep', sometimes for many years. That is, he does nothing to communicate with his sponsor or 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. The Soviets managed to recruit several people after World War I who reached high positions in Britain and in the U.S.
Those sleeper agents who have been discovered have often been natives of the target country who moved elsewhere in early life and been 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.
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.
The substitution sleeper agent was often surgically altered to appear as someone else but more recent versions tend toward androids or clones.
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.
There are a number of examples of sleeper agents found in science fiction and other forms of entertainment. Examples of sleeper agents include:
