[=MacGuffin=] (a.k.a. [=McGuffin=] or maguffin) is a term for a motivating element in a story that is used to drive the plot. It serves no further purpose. It won't pop up again later, it won't explain the ending, it won't do anything except possibly distract you while you try to figure out its significance. In some cases, it won't even be shown. It is usually a mysterious package/artifact/superweapon that everyone in the story is chasing.

To determine if a thing is a [=MacGuffin=]:
* ''Check to see if it is interchangeable.'' For example, in a [[TheCaper caper]] story the [=MacGuffin=] could be either the Mona Lisa or the Hope diamond, it makes no difference which. The rest of the story (i.e. it being stolen) would be exactly the same. It doesn't matter which it is, it is only necessary for the characters to want it.
* ''Does it do anything, and if it does, is it ever actually used in story?'' If the answer to both is yes, it's a PlotDevice, not a MacGuffin. For {{Plot Device}}s that get the same attention as a [=MacGuffin=], compare MagneticPlotDevice.

If it passes both of these criteria, congratulations: its a [=MacGuffin=]!

A common [=MacGuffin=] story setup can be summarized as "Quickly! We must find X before ''they'' do!".

The term was popularized by Creator/AlfredHitchcock, who credited one of his screenwriters, Angus [=McPhail=], with the creation of this concept and the name for it, citing a particular school-boy joke:

-->A man is riding on a train when a second gentleman gets on and sits down across from him. The first man notices the second is holding an oddly shaped package.
-->"What is that?" the first man asks.
-->"A [=MacGuffin=], a tool used to hunt lions in the Scottish highlands."
-->"But there are no lions in the Scottish highlands," says the first man.
-->"Well then," says the other, "That's no [=MacGuffin=]".

Hitchcock and Angus [=McPhail=] were not the first to formulate this concept. Silent-film actress Pearl White starred in cliffhanger serials (most famously "The Perils of Pauline") in which the characters spent most of their screen time chasing each other for possession of a roll of film, or some other doodad. This device occurred so often in Pearl White's serial films that she routinely referred to the coveted object as a "weenie", using the term precisely as Hitchcock would later use "[=MacGuffin=]".

In academic circles this is sometimes called the Golden Fleece, after the artifact from the myth of Jason and the Argonauts. The Fleece was first mentioned by the Greek poet Simonides, which makes this trope OlderThanFeudalism.

Contrast MockGuffin, for when an object that isn't really a [=MacGuffin=] is mistaken for one.

If you want to start [[JustifyingEdit arguing]] that your favourite series' most awesome magical thing isn't a [=MacGuffin=], remember that TropesAreTools. Having a [=MacGuffin=] is not necessarily bad writing, depending on how it's handled -- concretely defining or giving a central role to the object of a chase can ''detract'' from a work, if the point is to focus on the characters.

[=MacGuffin=] sub-tropes:
* [[AccidentallyBrokeTheMacGuffin Accidentally Broke The [=MacGuffin=]]]: When someone breaks the [=MacGuffin=] when he needed it.
* ArtifactOfAttraction: If the object itself is inherently irresistible.
* [[ClingyMacGuffin Clingy [=MacGuffin=]]]: Inversion of this trope -- its most important attribute is that the person who has it wants to be rid of it.
* [[DismantledMacGuffin Dismantled [=MacGuffin=]]]: The [=MacGuffin=] is split into several parts and hidden in different places. {{Plot coupon}}s are most often this type of [=MacGuffin=].

As you might have guessed from the sheer number of [[SubTrope sub-tropes]], this is a very common {{trope}} in fiction. So common, in fact, that it [[http://en.wikipedia.org/wiki/MacGuffin has its own page]] on TheOtherWiki.

'''Do not confuse with PlotDevice. Please, don't.''' Also not to be confused with the tribe from ''WesternAnimation/{{Brave}}'', or anyone of Scottish descent.

!!Other Examples:


[[folder:Fan Works]]
* In ''Fanfic/ThePrayerWarriors'', during "The Battle With the Witches", the heroes look for five keys to get into [[Franchise/HarryPotter Dumbledore's office in Hogwarts]]. One is carried by Ginny, another by Ron, a third by Harry, and a fourth by Hermione. It's unclear who has the fifth key, since after the fourth key, the Prayer Warriors break into Dumbledore's office and kill him.
* In ''FanFic/{{Pokeumans}}'' the Gemstone Files take this role at first, but are later replaced by [[MineralMacGuffin the Dimensional Gems]].
* ''FanFic/TheCaptainOfTheVirtualConsole'' has the Runestones, manifestations of players' love for gaming.

[[folder:Fairy Tales]]
* In ''Literature/CatherineAndHerFate'', the skein of silk that Catherine's Fate gives her is so apparently worthless that she nearly throws it out. It has, it turns out, two properties: it is exactly the color needed to sew the king's wedding garments, inspiring him to say that she shall have its weight in gold, and it outweighs his entire treasury, thereby inspiring him to demand her story.

[[folder: Tabletop RPG]]
* The ''TabletopGame/{{Paranoia}}'' adventure "The Yellow Clearance Black Box Blues". The title Black Box. What it does is eventually revealed, in some versions of the adventure, but it's unlikely your player characters will live long enough to discover it.
* The "Honor & Intrigue" system has a character attribute actually called [[LampshadeHanging [="MacGuffin"=]]]. Taking it turns one of the items in your character's possession into a future [=MacGuffin=].
* Referenced in ''[[TabletopGame/MistbornTheOriginalTrilogy Mistborn Adventure Game]]'', where the book uses the term "MacGuffin" to describe a Secret that has no function other than to be the thing everyone wants. For example, a vast hoard of precious metal that may or may not exist, and which is of little use anyway, because the world is coming to an end and there's nothing to buy with that wealth.

* In ''Theatre/{{Philoctetes}}'', while much is made of Philoctetes' special bow (received from Herakles himself) the plot itself is not really concerned with its purpose as much as the choices the characters make because of and in spite of its importance.
* In ''Theatre/SherlockHolmes'', the [=MacGuffin=] is a packet containing letters, photographs, jewelry etc. that were sent to Alice Faulkner's late sister by a foreign gentleman who seduced and ruined her, and the villains want it out of the picture now that he wants to marry. The name of the gentleman is merely whispered inaudibly, and the sister's name is not revealed either.

[[folder:Theme Parks]]
* As in the first movie, the all-powerful [=AllSpark=] shard is this in ''Ride/TransformersTheRide''.
* In ''Ride/JimmyNeutronsNicktoonBlast'', Jimmy's advanced Mark IV rocket ship is sought after by the Yolkians, who believe that it can be used to enslave the earth if duplicated.

[[folder:Visual Novels]]
* Mary's eye in ''VisualNovel/ShikkokuNoSharnoth''. We know what the eye does for ''her'' but exactly how it would really help anyone else who acquired it is vague. They simply want it.

[[folder: Web Original]]
* The Project Orwell software in series 1 of ''WebVideo/KateModern'', which is mysteriously absent from the second series.
* WebVideo/TheNostalgiaChick has a jar of mayonnaise that has been transformed into one by [[ExactlyWhatItSaysOnTheTin Lord [=MacGuffin=]]].
* The Tower of Pimps, a stack of four gold blocks on an obsidian block pedestal, in ''Creator/RoosterTeeth'''s, "LetsPlay ''VideoGame/{{Minecraft}}''". Nothing fancy, just bragging rights material for whoever wins the challenge of the episode.
* The dimensional transponder in ''WebVideo/TheCartoonMan'' [[spoiler:which turns out to be [[ChekhovsGun a pen the characters found earlier.]]]] In the third movie, [[spoiler: the Glove of the Animator becomes one as well.]]
* This trope was featured in Episode 2 of the TV Tropes podcast ''Podcast/OnTheTropes''.
