A smark is abbreviated professional wrestling slang. The term is a hybrid of "smart mark," two other terms in their own right. A "smart" is a person who is privy to the behind-the-scenes operations and understands that pro wrestling is scripted, whereas a "mark" is one who believes that pro wrestling is real. A "smark," therefore, is a combination of the two, a wrestling fan who realizes that pro wrestling is scripted, but still enjoys the on-screen product as much as the off-screen affairs.

Smarks are a small and anomalous subset of the pro wrestling fanbase. They come from a many different social background and are often referred to as "smart" fans. Many smarks are part of the "IWC," or Internet Wrestling Community, a general term for the legions of fans of wrestling that use the Web as their means of communication. Smarks also make themselves heard on television, much to the chagrin of show producers: cities like New York, and Philadelphia, as well as any city in Canada, are notorious for having an audience that knows just a little too much.

Smarks define themselves by embracing the "workrate," or talent level, of wrestlers. They will spite the celebrated "big men" in favor of smaller, faster wrestlers with a wider variety of moves.

Many smarks also investigate foreign wrestling, particularly Japanese. One reason for this is many smarks believe that Japanese wrestling has a better workrate and has better workers.
