In professional wrestling, kayfabe (pronounced /ˈkeɪfeɪb/) is the portrayal of events within the industry as "real" or "true". Specifically, the portrayal of professional wrestling, in particular the competition and rivalries between participants, as being genuine or not of a worked nature. Referring to events or interviews as being a "chore" means that the event/interview has been "kayfabed" or staged, or is part of a wrestling angle while being passed off as legitimate. Kayfabe has also evolved to become a code word of sorts for maintaining this "reality" within the realm of the general public.

Kayfabe is often seen as the suspension of disbelief that is used to create the non-wrestling aspects of promotions, such as feuds, angles, and gimmicks, in a similar manner with other forms of entertainment such as soap opera or film. In relative terms, a wrestler breaking kayfabe during a show would be likened to an actor breaking character on camera. Also, since wrestling is performed in front of a live audience, whose interaction with the show is crucial to the show's success (see pop), one might compare kayfabe to the fourth wall, since there is hardly any conventional fourth wall to begin with.
