''Tartuffe, ou, l'Imposteur'' is possibly the most famous play of Jean-Baptiste Poquelin, a.k.a. Creator/{{Moliere}}. Tartuffe is a con man who has the well-to-do Orgon convinced that he's a pious, generous, and all-around good guy. Everyone else (save for Orgon's mother) can see right through the ruse and try desperately to make Orgon see Tartuffe for the fraud he is -- especially when Orgon disinherits his son in Tartuffe's favor and attempts to make his daughter jilt her eligible suitor to marry the hypocrite. Worse yet, Orgon has admitted covering for a friend involved in a political plot -- and Tartuffe has no scruples about informing when this proves to be advantageous to him.

Published and performed in 1664, ''Tartuffe'' almost immediately drew the ire of some Catholic clerics (notably the Archbishop of Paris), who believed the play to be an attack against them (partly because, in the earliest performances, Tartuffe was costumed like a ''dévot'', a member of the extreme Catholic party at court). They banned the play and threatened to excommunicate anyone who performed in or even saw it. In later versions, the author revised the character, to make him more secular. Fortunately for the dramatist, the King remained firm in his support, and he was able to avoid the threatened excommunication.

!!''Tartuffe'' provides examples of the following tropes:

* AllMenArePerverts: Played with, as one scene has Tartuffe going on at length (in-character) how one female character is showing too much cleavage. However, it's also obvious he's admiring the view.
* AntagonistTitle
* ArrangedMarriage: Orgon tries to marry off his daughter Mariane to Tartuffe.
* CatchPhrase: In an early scene, when Dorine is describing how Tartuffe has been gorging and swilling while while Elmire had been suffering from a dangerous illness, Orgon's only response is a repeated, "The poor man!" [[BorrowedCatchphrase Dorine later uses the phrase herself ironically.]]
* ConMan: Tartuffe is basically one.
* DeadpanSnarker: Dorine, Mariane's handmaiden, has this trope in spades. Mariane isn't bad either.
* DeliberatelyPainfulClothing: The titular character wears a hair shirt... but in a sign that his supposed piety is all an act, he wears the shirt ''inside out'', so that he doesn't actually feel any discomfort.
* DeusExMachina: At the end of the play [[spoiler: the King has Tartuffe sent to prison for numerous unspecified crimes.]] [[PanderingToTheBase It is a comedy, after all, made with King's money.]]
* DirtyOldMonk: Tartuffe is a lecher pretending to be a man of God.
* EngineeredPublicConfession: Tartuffe reveals his true colors to Elmire, unaware that Orgon is listening.
* GrandeDame: Madame Pernelle, the Matriarch, is the only one besides Orgon who is taken in by Tartuffe's ruse. In the opening scene she complains that nobody pays attention to her.
* HidingBehindReligion
* HoistByHisOwnPetard: [[spoiler:The documents Tartuffe reveals to the king contain proof to his real identity.]]
* HorribleJudgeOfCharacter: No, really, Orgon, he is ''not'' a good person. Really.
* HotBlooded: Damis
* {{Hypocrite}}: Not only Tartuffe, but his unseen man-servant as well; also Monsieur Loyal the bailiff.
* INeedToGoIronMyDog
-->''TARTUFFE: Sir, it is half-past three; certain devotions \\
Recall me to my closet; you'll forgive me \\
For leaving you so soon.''
* MoralGuardian: Tartuffe acts like this in Orgon's house towards pretty much everything, from daily activities to fashion.
* OnlySaneMan: Cléante, Orgon's brother-in-law, represents common sense. The argument could also be made that this trope is inverted, and Orgon is the Only Dumb Man.
* ReversePsychology: When Damis catches Tartuffe trying to seduce his mother, he denounces the hypocrite to Orgon. Tartuffe turns the tables by declaring that, [[SarcasticConfession yes, he is a liar, a sinful man, a miserable deceiver]] -- which convinces [[WhatAnIdiot Orgon that Damis has slandered his sinless, humble friend]] and causes the old man to turn his son out of the house.
* RichInDollarsPoorInSense: Orgon. By the time he realizes Tartuffe is a fraud, [[spoiler: he's given the man the deed to his estate.]]
* ServileSnarker: Dorine.
* SinisterMinister: Tartuffe, who uses his faux charisma as a façade by which he can scheme against his host, Orgon.
* TakeThat: Against [[EvilJesuit casuistry]].

!!Particular productions or adaptations contain examples of:

* LastSecondWordSwap: In Justin Fleming's translation, which like the original is in rhyming verse, Damis has a rant about Tartuffe that rhymes "blunt" with "''[significant pause]'' runt".
* SettingUpdate:
** A translation by Australian playwright Justin Fleming sets the action in 21st-century Australia, making use of Aussie slang and incorporating a number of topical jokes. The deus ex machina at the end takes the form of a TV news crew finishing up an investigation into Tartuffe's activities.
** An adaptation by actor/author/comedian Andy Jones in rhyming couplets uses a setting of 1939 Newfoundland (that is, before confederation with Canada) and many words and phrases unique to the province.
