Sleeper in the psychology context, often referred to as the sleeper effect, is a phenomenon where a message or information initially has little to no persuasive impact on an individual but becomes more influential over time. This effect is usually observed in situations where the message is accompanied by a discounting cue, such as a dubious source or weak argument, which initially undermines its persuasiveness. Over time, however, the association with the discounting cue diminishes, and the message gains influence, seemingly "sneaking up" on the individual.

It can refer to the usual state preceding falling asleep, the condition of being in a drowsy state due to circadian rhythm disorders, or a symptom of other health problems.
