''Le Petit Nicolas'' (''Little Nicolas'') is a series of children's books by Creator/ReneGoscinny and illustrated by Jean-Jacques Sempé, about a little French boy and his friends. It started out in 1957.

The short stories focus on the main character's everyday life and range from causing mischief at school to helping dad paint the kitchen, playing with friends at the junkyard and generally getting into trouble.

In 2009, it was adaptated into a CGI animated series and a live-action movie.

Contains examples of:

* AdaptationDyeJob: Nicolas' mom, originally light-haired in the illustrations, becomes a brunette in the animated series and the movie.
* AgeAppropriateAngst: A lot.
* ArtEvolution: Compare the original art with the latest ones; the heads got bigger, the noses less round, the lines thinner...
* AscendedExtra: Louisette, who originally appeared in only one chapter, becomes a main character in the animated series.
* AwLookTheyReallyDoLoveEachOther: Happens frequently to Nicolas' parents after a harsh argument.
* BadlyBatteredBabysitter: Nicolas' one-time babysitter didn't spend a very peaceful night.
* BigEater: Alceste IS this trope.
* BitchInSheepsClothing: Louisette, who bullies Nicolas while her mother isn't looking and bats her eyelids at her, making her convinced she is being a very nice girl.
* DubNameChange:
** In the Polish translation, some of the kids' names get changed to exotic-sounding names which are nevertheless easier to read and pronounce for Polish speakers (Geoffroy becomes Gotfryd, Clotaire becomes Kleofas, etc.)
** The English translation also changed some characters' names, but to more normal English ones.
* ExactWords: Nicolas once gets becomes first of his class during a test... because the entire class is sick at home.
* GagNose: One episode has Nicolas buying a big red plastic nose that supposedly looks like his uncle Eugene's, and he wears it in class, with predictable results.
* HairColors: Nicolas has black hair, which is helpful in finding him in crowd pictures.
* HeyItsThatGuy: Not even [[LesChoristes Clément Mathieu]] could get the kids to sing in TheMovie.
* HypocriticalHumor: Makes up about half of the endings.
* InnocentInaccurate: PlayedForLaughs. A lot of the humor comes from Nicolas innocently misunderstanding the adults' behavior.
* LonelyRichKid: Averted with Geoffroy, whose family is extremely rich but who is still in with the gang. He has a conflictual relation with them, but then, everyone in it does.
* TheMovie: Came out in 2009, with Maxime Godard as Nicolas, Kad Merad as his dad and Valérie Lemercier as his mom.
* NerdGlasses: Worn by Agnan, and he is the only one with glasses in the class. [[YouWouldntHitAGuyWithGlasses And these are the reason why the other kids don't punch him in the face as often as they'd like.]]
* NerdsLoveToughSchoolwork: Agnan, who spends every recess studying.
* NotInFrontOfTheKid: Nicolas' mother sometimes says that when she gets into an argument with his father.
* OutOfCharacterMoment: [[spoiler:In the live-action film, Agnan]] tries to POISON his new teacher with old chocolate because [[spoiler:she has replaced the teacher he likes.]]
* SarcasmBlind: Being a kid, Nicolas usually takes the sarcastic comments of adults literally.
* ShoutOut: In the English translation, the swot Agnan is renamed Cuthbert. This is probably a Shout Out to Cuthbert Cringeworthy, the swot character in "[[ComicBook/TheBeano The Bash Street Kids]]".
* SitcomArchNemesis: Blédurt to Nicolas' father, who are always trying to outdo each other [[WomenAreWiser until their respective wives bring an end to it.]]
* SliceOfLife
* StandardFiftiesFather: Comes home from an exhausting day at the office, just wanting to read his newspaper in peace and quiet...
* StayInTheKitchen: Nicolas' father once made the mistake of using this. He regretted it.
* TeachersPet: Played straight with Agnan.
** Subverted in a storyline where the class gets a substitute teacher, who favours ButtMonkey Clotaire over Agnan.
* TomboyAndGirlyGirl: Louisette and Marie-Edwige in the animated series.
* TookALevelInJerkass: Marie-Edwige in the animated series becomes somehow nastier...
* TookALevelInKindness: ... while Louisette becomes nicer.
* UnnamedParent: Nicolas' parents.
* UnreliableIllustrator: Sempé's illustrations would often contradict the text. Examples include:
** During the visit at the museum episode, Alceste is described as looking at a "small painting", but the illustration shows the painting being ten times his size. Later, the text says Alceste is carrying it under his arm... which would be quite difficult, now, wouldn't it?
** During the vacations episodes, a boy called Crépin gets a visit from his parents. He is described as having curly hair. The illustration shows him with straight hair.
** In another vacation episode, Nicolas and other boys are being bothered by three girls. One of them, Micheline, is described as being fat, and yet the illustrations show the girls all being thin. What is worse, when Micheline is described as slapping a boy, clawing another one and getting her pigtails pulled, a ''different girl'' is shown each time... and in the last case, there are suddenly ''two'' girls with pigtails, even though they were previously shown with different hairstyles.
* VitriolicBestBuds: Pretty much all of the main kids, who almost always get into fights when they meet. However, they regard it as good fun.
* YouLie: You could make a drinking game of the number of times a boy calls the other a liar, especially when it is Geoffroy being called so.
* WomenDrivers: One story is about Nicolas' mom trying to get her driver's licence, with such incidents like her claiming she didn't see a tree that jumped into the road. In the end, she passes, but it's so frustrating she swears off driving.
