[-[[caption-width-right:350:[[Theatre/{{Macbeth}} Double, Double, Toil and Trouble,]] [softreturn] [[EEqualsMCHammer Time Dilation]], Edwin Hubble.]]-]

Stereotypically speaking, in fiction, [[DumbBlonde blondes are lacking in intelligence]], [[FieryRedhead redheads have short tempers]], so, [[BlondeBrunetteRedhead out of the trio]], [[BeautyBrainsAndBrawn brunettes are all brain]]. Like the DumbBlonde, the brunette varies quite a bit. They can bashfully hide behind their books or [[{{Meganekko}} glasses]], with their hair done in pigtails or a bun or they can boldly use their smarts for their ambitions. Whichever it is, their knowledge is real--if she's on your side, then you can always count on her smarts in a fix. She may be a HotLibrarian, a HotScientist, or even a WrenchWench. If so, her SesquipedalianLoquaciousness and/or TechnoBabble will [[GeekyTurnOn turn people on]]. And she always has nice, thick, brown locks. What they don't (necessarily) have is strength, like the SquishyWizard (who may be TheSmartGuy himself), as they care more about their mind than their body. That's what makes a BadassBookworm so interesting, a rare combination.

This trope doesn't mean that blondes and redheads can't be [[TheSmartGuy the brains of the outfit]]. It's just more common for them to have brown hair, especially if they're female, although there are some male examples.

If she's part of a FourTemperamentEnsemble, she's probably Phlegmatic.

Contrast DumbBlonde and FieryRedhead. And, as with both of them, this character can be either good or evil. Compare RedheadsAreUncool who might stand out as much as the brunette but have less confidence than even the bashful brainy brunette.



* The Brown M&M seems to be this, with glasses and all.

[[folder:Anime & Manga]]
* [[ActionGirl Lita]] from ''Animerica'', in contrast to the blonde Janine and [[FieryRedhead red-headed Jessica]]. There's also Wendy, Ron's older sister, and his previous LoveInterest, [[ShyBlueHairedGirl Yukina]]. [[DeadpanSnarker Kasuse]] and [[GeniusBruiser Yusuke]] may count, as well as [[spoiler:Maya, Lita's CoolBigSis.]]
* [[NationsAsPeople Lithuania]] from ''Webcomic/AxisPowersHetalia'' is more serious than Germany, shown to be very efficient in battle smarts when he feigns a retreat and fools Prussia, and he's one of the ''[[PlentyOfBlondes very]]'' [[PhenotypeStereotype few Northern European countries]] with brown hair. It helps that his [[HeterosexualLifePartners former partner]] [[CloudCuckooLander Poland]] is an almost perfect {{Dumb Blond|e}}. Russia even lampshades this when the Polish-Lithuanian commonwealth is partitioned and he drags Lithuania away, commenting that he looks smart.
* Yomi from ''Manga/AzumangaDaioh'' fits this trope nicely. Excluding ChildProdigy, Chiyo, she's easily the smartest member of the group (with the possible exception of Sakaki).
* ''Manga/AttackOnTitan'' gives us Hange Zoe. Eccentric, intuitive, and ''obsessed'' with understanding the Titans, she is the closest thing to a scientist in the Scout Regiment. She also wears glasses.
%%* MagnificentBastard Lelouch Lamperouge from ''Anime/CodeGeass''.
%%* Light Yagami from ''Manga/DeathNote''. A brown-haired EvilGenius.
* ''Anime/ElHazardTheMagnificentWorld'''s Afura Mann, the wind priestess of Mt. Moldune. She's portrayed as the most intellectual of the three and, in ''The Wanderers'' series, she has her very own library!
* Sheska from ''Manga/FullmetalAlchemist''; an extreme bibliophile with a photographic memory of everything she reads.
%%* ''Manga/GirlFriends'' has the bookish Mari, in contrast to her best friend, the BookDumb Akko.
* Chao Lingshen and Satomi Hakase from ''Manga/MahouSenseiNegima''. Also, Yue and Nodoka, [[YouGottaHaveBlueHair for a given value of "brunette"]].
* ''Anime/MazingerZ'' gives two examples with TheProfessor Gennosuke Yumi and his daughter, Sayaka. Although she is an ActionGirl, she is pretty smart and knowledgeable.
** Hikaru Makiba from ''Anime/UFORoboGrendizer'' was one in the ''MazingerAngels'' spin-off.
%%* ''Anime/{{Naruto}}'' gives us Shikamaru Nara, who is known for his 200+ IQ.
* Despite his [[LovableCoward cowardice]] and [[BadLiar habitual lying]], Usopp from ''Manga/OnePiece'' is the brains of the Straw Hats. Also team archaeologist Robin.
** There's also Chopper, who acts as the crew's doctor. He's also a reindeer, so the brunette part is kind of justified.
* ''Manga/OuranHighSchoolHostClub'': Haruhi Fujioka. Though nobody in the host club is truly unintelligent, Haruhi is book smart to the point of being occasionally portrayed as a nerd, and possesses more common sense than most of them. Not to mention that everybody is gay for Haruhi.
* ''Manga/MakenKi'': Yan-Min is a Chinese foreign exchange student, who's highly proficient in martial arts and has near encyclopaedic knowledge about the various [[KiManipulation applications]] [[LifeEnergy of Element.]] In chapter 55, she astounded Aililu and Lilu by explaining the nature of "Black Element" and in chapter 87, she was able to [[AwesomeByAnalysis explain the process]] of combining her own "Blue" Element with Azuki's "Green" and Celia's "Red" to create [[LightEmUp "White".]] Which is [[spoiler: the only thing that [[KryptoniteFactor can hurt]] [[BigBad Yamato Takeru]]]].
%%* Yomiko Readman from ''Anime/ReadOrDie''.
* ''Franchise/SailorMoon'': Usually averted in the manga but played straight in the anime:
** Nephrite has brown hair but was depicted as brash and cocky in the manga. When the series was first adapted, he kept his brown hair but [[AdaptationPersonalityChange was changed to a serious and intelligent individual and a skilled planner and manipulator]].
** Gurio Umino, Shingo Tsukino and Reika Nishimura are all brilliant students in all continuities but [[AdaptationDyeJob became brunettes]] for the same anime adaptation (of the three, only Umino kept his brown hair for ''Crystal''). Apparently, someone who worked on the first anime season was fond of this trope.
** Haruna Sakurada has light brown hair in ''Anime/SailorMoonCrystal'' and she is a teacher (in the other anime series, her hair was a deep red with a [[FieryRedhead fiery temper to go with it]]).
* Leo Regulus from ''Manga/SaintSeiyaTheLostCanvas'', said and proven to be a battle genius.
* Hakkai from ''Manga/{{Saiyuki}}'' is the intellectual of the ikkou. He could have had his pick of college scholarships had he wanted to continue his formal education, takes correspondence courses (including lockpicking, which becomes very helpful), reads thick obscure books, and worked as a school teacher until Kanan's death.
%%* ''Anime/{{Vandread}}'' gives us Parfait, who is a WrenchWench.
%%* InsufferableGenius Seto Kaiba from ''Anime/YuGiOh''.
* ''Manga/BungouStrayDogs'' gives us strategic geniuses Dazai Osamu, Mori Ougai, and Fyodor Dostoyevsky, and detective extraordinaire Edogawa Ranpo. Louisa May Alcott, another strategist, may count, but her hair is very light brown. Outside the manga, there's also Taguchi Rokuzou (a hacker) and Sasaki Nobuko (a university lecturer and criminal genius).

[[folder:Comic Books]]

* Peter Parker aka ''Franchise/SpiderMan'', a TeenGenius as a youth and still a science prodigy into his adulthood.
* ''ComicBook/LoisLane'' in Franchise/{{Superman}} continuities where she's not a FieryRedhead. And where [[IdiotBall she's actually brainy]].
* ''Comicbook/{{Supergirl}}'': Kara Zor-El's SecretIdentity (Linda Lee Danvers in the Silver Age, Linda Lang in the post-Crisis universe, Kara Danvers in ''Comicbook/SupergirlRebirth'') is always a brown-haired, nerdy girl. Earth's science is pretty primitive to her.
* Leading expert on Gamma Radiation Dr Bruce Banner, aka ''ComicBook/TheIncredibleHulk''. The Hulk himself usually isn't a genius (He's not dumb, but he's no Banner) and usually isn't brunet either.
* ''ComicBook/XMen'':
** Nobel Prize-winning geneticist Moira [=MacTaggert=].
** As well as self-proclaimed "Goddess of Computers" ComicBook/KittyPryde.
* ComicBook/{{Impulse}}: Despite being largely BrilliantButLazy Bart has a PhotographicMemory and is actually [[DitzyGenius quite smart]] and knowledgeable about technology. Highlighted after he [[SuperSpeedReading read an entire library]] in an afternoon while recovering from being kneecapped.

[[folder:Fan Works]]

Ponder has an ineasy feeling she might turn out to be brighter than he is. Ruth appears in the ''{{Discworld}}'' of Creator/AAPessimal.

[[folder:Films -- Animation]]
* Belle from Disney's ''Disney/BeautyAndTheBeast'' is treated like an outcast in her village because she loves to read books. And yep, she's a brunette.
* Jane Porter from Disney's ''Disney/{{Tarzan}}'' is similar to Belle from above. She is not only knowledgable in zoology, but also smart enough to teach an adult who has ''never learned how to communicate like a human'' English, not to mention intruduced him to physics, music, astronomy, dance and geography. And yep, she's a brunette.
* Edna Mode and Elastigirl from ''WesternAnimation/TheIncredibles''.
* Hiccup from ''WesternAnimation/HowToTrainYourDragon''. He manages to figure out a way to make Toothless able to fly again.
* Maria Posada from ''WesternAnimation/TheBookOfLife''. She is probably the most rational, cultured person in the story.
* Tip from ''WesternAnimation/{{Home}}'' is described as a very resourceful girl. This proves to be true, when she's able to take care of herself when her mother is kidnapped.
* Tiana from ''Disney/ThePrincessAndTheFrog'' is incredibly resourceful, clever and observant. She's also a brunette.

* Evelyn in ''Film/TheMummy1999''. She's also a HotLibrarian.
* Mocked in ''Film/WhereTheTruthLies'':
-->'''Lanny:''' My favorite catches were the intellectuals. They'd be the ones in the straight black dresses, severe black hair. Your basic neurotic, eyeglasses, cool jazz, liberal, "I'll fuck any black guy as part of my personal apology for racism in America" type.
** The person reading his letter then looks across the room and sees a bookish-looking brunette. And you automatically imagine her doing one thing and one thing only...
* Jenny in ''Film/AnEducation'' dreams of getting into Oxford, and she's got the brains to do it. She has a {{foil}} in DumbBlonde Helen.
* Inverted in ''Film/JennifersBody''. The brunette Jennifer is a vapid AlphaBitch (both before and after she is [[DemonicPossession possessed]]), while the blonde Needy is a HollywoodNerd, complete with [[NerdGlasses the glasses]].
* Ariadne in ''Film/{{Inception}}''.
* There's magazine writer Summer from ''Film/DefinitelyMaybe''.
* Emma from ''Film/NoStringsAttached'', who studied at MIT, is a doctor in Boston, and turned up to a pajama party in actual pajamas in her college days.
* The film ''Baby Mama'' paired brunette Creator/TinaFey with blonde Amy Poehler. Guess what their characters' personalities were.
* The [[AdaptationDyeJob previously blonde]] Trillian became this in the film adaptation of ''Film/TheHitchhikersGuideToTheGalaxy''.

** [[Characters/XMenFilmSeriesProfessorCharlesXavier Charles Xavier]] when he still has hair in the [[Film/XMenFirstClass First]] [[Film/XMenDaysOfFuturePast Class]] [[Film/XMenApocalypse trilogy]]; he has a doctorate in genetics from the University of Oxford.
** Hank [=McCoy=] in the First Class trilogy; he's a doctoral-level scientist who graduated from Harvard University at the age of 15.
* Franchise/MarvelCinematicUniverse
** Loki is a master of magic, which makes him the equivalent of a {{Bookworm}} on Asgard because magic and science are the same thing in that realm.
** Dr. Jane Foster is an astrophysicist.

* Myra from the ''Literature/NightfallSeries'' is a brown-haired bookworm, who joins the mission against Prince Vladimir because she can contribute with her ideas. When she ends up a captive in the palace, she needs to rely on her wits to survive.
** Prince Vladimir, a dark-haired WickedCultured ManipulativeBastard, serves as a villainous male example.
* Hermione Granger from ''Literature/HarryPotter'' is the cleverest student in her year, and she also is a brunette.
* Lessa from ''Literature/DragonridersOfPern'' qualifies as she is not only the one to figure out Threadfall patterns and trick a Dragonrider into challenging a Lord Holder to a death match, but she also figures out how to save the planet and then does it against the wishes of everyone else involved.
* Tiffany Aching of the ''Literature/{{Discworld}}'' books, who read the dictionary for fun when she was a girl, always pestered traveling scholars with difficult questions, and turned out to be very clever and talented for a witch her age.
** Another Discworld example is [[Discworld/GoingPostal Adora Belle Dearheart]] the city's leading golem expert. She even speaks their language, reputed to be very hard for humans to learn. She's also one of the series' biggest examples of DeadpanSnarker. And this is [[WorldOfSnark Discworld]]!
* Jo March in ''Literature/LittleWomen'' has thick chestnut hair, "her one beauty", and is a devoted writer.
* October "Toby" Daye in ''Rosemary And Rue'' is a tough and savvy private investigator who servers both mortal and faerie clients.
* ''Literature/ASongOfIceAndFire'':
** Petyr "Littlefinger" Baelish is an EeriePaleskinnedBrunette and is not only a financial genius but a MagnificentBastard who has the whole continent of [[CrapsackWorld Westeros]] dancing to his tune.
** Several of the Tyrells also have this trait, the eldest son and heir Willas being a noted scholar (to make up for his crippled leg), and Margaery having no small amount of her own political nous.
* Amelia Marsh in ''Literature/DarknessVisible'' borders on the black end of the spectrum and is very intelligent/educated for a woman of her era. She speaks French, paints beautifully, and, to Lewis's surprise, can play chess. [[SassySecretary Mrs Emiline Pound]] also counts, though her hair is going gray. It is her tireless work in the Warden's archives which [[spoiler:finally reveals the identity of the traitor among them.]]
* Claudia's sister Janine from ''Literature/TheBabySittersClub'' is an exaggeration with her AsianAndNerdy ways. Claudia feels bad when she compares herself to her genius sister.
* Anji Kapoor, from the ''Series/DoctorWho'' Literature/EighthDoctorAdventures, is a genius or very close to it when it comes to economics, to the point of seeming to be [[BollywoodNerd a bit of a nerd]] when you get her started on the topic.
* The Baudelaire siblings from ''Literature/ASeriesOfUnfortunateEvents'' since they are able to escape from many dangers relying only on their skills and knowledge.
* Jane Eyre, the title character of ''Literature/JaneEyre'' by Charlotte Brontë, shows us that this trope is at least OlderThanRadio. She's an intelligent woman with brown hair, who works as a teacher.
* Magdalena Swär in "De skandalösa" by Creator/SimonaAhrnstedt, is similar to Jane Eyre in both background, personality and appearance. So of course, she too is an intelligent woman with brown hair.
* Keladry, the protagonist of Creator/TamoraPierce's ''Literature/ProtectorOfTheSmall'', is described as having mousy brown hair. She's a GeniusBruiser whose favorite subject is math, and her classmates frequently ask for her help. During the dull stretches of managing her refugee camp in the fourth book, she amuses herself with engineering projects.
* ''Literature/TheInfernalDevices'':
** Tessa Gray is a wide reader and quotes poetry quite often. She has the potential to lapse into BadassBookworm territory.
** Charlotte Branwell is ''very'' intelligent.
* ''Literature/{{MARZENA}}'' gives Dutch Psychotherapist Livia, who also works in Psy-Ops. There's also possibly Dr. Lauren, an expert neurologist and neurosurgeon, although the color of hair is never mentioned.
* [[MeaningfulName Prudence]] and [[AcademicAthlete Sally]] in ''Literature/DontCallMeIshmael''. Prudence is described as "nearly a [[TeenGenius genius]]", plays three instruments and is usually seen reading {{doorstopper}}s. Sally is the best in her year.
* Linh Cinder from ''Literature/TheLunarChronicles'' is a clever DeadpanSnarker who is also the best mechanic in New Beijing.
* In ''Literature/TheAnderssons'', Ida Sofia is the BookWorm out of the four original Andersson sisters. And yep, she also is a brunette.

[[folder:Live-Action TV]]
* ''Series/{{Angel}}'': Fred Burkle was a physics student and later the head of the company's Science Division with long wavy brown hair. Her high intelligence was a great asset to the [[FanNickname "Fang Gang"]].
* ''Series/BuffyTheVampireSlayer'': Subverted with Cordelia who was shown as an example of the BrainlessBeauty. Though, after exams, it was revealed that she actually had very good grades which she simply chose to hide from her peers, thinking it would make her less popular.
* Alex P. Keaton from ''Series/FamilyTies'', played by the brown haired Creator/MichaelJFox. Out of all of the Keaton family, he's the most studious and even has a choleric, Type A personality to boot.
* ''{{Series/Firefly}}'': River Tam, who is considered a child prodigy, intelligent beyond her years and athletically gifted. At one point Book finds her marking up his bible and she tells him that she's fixing it because the contradictions mean it's broken. She has unkempt brown hair.
* Creator/SummerGlau's character Bennett Halverson on ''{{Series/Dollhouse}}''.
* Summer Glau as Orwell in ''Series/TheCape''.
* [[OnlySaneEmployee Liz Lemon]] on ''Series/ThirtyRock''. Emphasized by the fact that the show's two other female regulars are both {{Dumb Blonde}}s. In fact, every character ever played by Creator/TinaFey.
* ''Series/GameOfThrones'':
** Talisa is dark haired and is a highly competent nurse and fully capable of engaging Robb in a debate.
** Margaery has light brown hair and is a very adept conversationalist and manipulator.
* Chuck in ''Series/PushingDaisies'' has a great general knowledge and speaks seemingly every language known to man.
* Joey Potter on ''Series/DawsonsCreek''.
* ''Series/GilmoreGirls'': All three eponymous Gilmores fit the bill in varying degrees. Rory, the youngest, is the most clearcut example - a CuteBookworm member of the GeniusBookClub and a GoGetterGirl. Her mother Loerlai is a more offbeat example - a BunnyEarsLawyer who is an incredibly quick thinker. Unike her daugther, she is more street smart than book smart. Emily, the grandmother, is a BrainyBrunette of the ManipulativeBitch persuasion, rounding up a trio of book/street/people smarts.
* Sarah Mackenzie from ''Series/{{JAG}}''.
* ''Series/{{Bones}}'': Temperance Brennan, and basically every other main character.
* ''Series/{{NCIS}}'':
** Abby Sciuto. Underneath her punk groupie looks, she's a scientist and Mensa member.
** Ziva is clever, with her smart-ass comments, multiple languages, skill with weapons, and PhotographicMemory.
* Most of the brunettes in ''Series/{{CSI}}'' probably qualify; Sara Sidle definitely does.
** Carries over to ''Series/CSINY'' and probably ''Series/CSIMiami'' as well. All the casts have several smart brunettes.
* At least in the later seasons, Chloe O'Brian in ''Series/TwentyFour''.
* Possible subversion in ''Series/{{Privileged}}'': Megan, the Yale graduate, is shown as a redhead; however, in the first episode, we're told that she dyed it red and we never really learn her natural colour, so it's possible she's simply a BrainyBrunette in disguise.
* ''Series/GossipGirl'': Blair Waldorf is both a book smart GoGetterGirl ''and'' a cunning ManipulativeBitch.
* ''Series/TheVampireDiaries'': Elena, Bonnie, and some of the recurring characters as well (including ManipulativeBitch Katherine).
* Detective Kate Beckett from ''Series/{{Castle}}''.
* Lindsay Weir on ''Series/FreaksAndGeeks'', though she is a reluctant one - her plotline revovles mostly around her desire to be more than just a brain.
* Emily Prentiss from ''Series/CriminalMinds''. Her predecessor, Elle Greenaway, was also intelligent, but Emily gets more credit because she has yet to [[VigilanteExecution be dumb enough to kill someone in cold blood]]. [[TheWoobie Special Agent Doctor Spencer Reid]] also qualifies.
* In ''Series/DoctorWho'', Zoe [[CrowningMomentOfAwesome can blow up a computer]] with her brain. And Romana I is repeatedly shown to be smarter than the Doctor. Of course, Barbara was the very first brainy companion, being a history teacher. And let's not forget widely beloved IntrepidReporter [[Creator/ElisabethSladen Sarah Jane Smith]], who is repeatedly shown both on ''Series/DoctorWho'' and ''Series/TheSarahJaneAdventures'' to be quite intelligent, considering she [[Series/TheSarahJaneAdventures saves the Earth]] roughly every week. In [=NuWho=] there's medical student Martha. Also Clara, who's graduated from nanny to schoolteacher since she was introduced and whose alternate Victorian governess self was relatively blasé about the TARDIS being BiggerOnTheInside.
* ''Series/{{Community}}'': Annie Edison is a GoGetterGirl example.
* Averted and played straight in ''Series/NoOrdinaryFamily''. Stephanie is a world-class [[HotScientist research scientist]] who graduated from MIT and is blonde. Her nerdy yet attractive sidekick Katie, also shown to be very intelligent, is a brunette.
* George from ''Series/BeingHumanUK'' is described as having a brain like a "planet" and is said by several characters to be able to carry a much more prestigious job than hospital janitor if he wanted.
* ''Series/{{Carrusel}}'' has Valeria, Carmen, and Alicia, to a lesser extent. All 3 girls have jet black hair and are good students. Valeria is a talented painter. Carmen is very good with people. And Alicia is very mature and has common sense.
* Dr. Helen Magnus of ''Series/{{Sanctuary}}'', OmnidisciplinaryScientist extraordinaire, whose long brunette locks are a stark contrast to Creator/AmandaTapping's [[YouMightRememberMeFrom former role]] as the short-haired, blonde, and equally brainy astrophysicist Major Samantha Carter on ''Series/StargateSG1''. [[IAmNotSpock This was probably deliberate]].
* The younger Dunphy daughter, Alex, on ''Series/ModernFamily''.
* Maggie from ''Series/UnnaturalHistory''.
* ''Series/TheBigBangTheory'': Amy Farrah Fowler and Leslie Winkle (both Ph.Ds). Sheldon's assistant Alex was this too.
* Rocky Blue from ''Series/ShakeItUp''.
* Played with on ''Series/TeenWolf''. While dark-haired Stiles and Danny are both very smart (Stiles in terms of research and Danny in terms of technology) and the other brunette characters are ''certainly'' no slouches themselves, the smartest character on the show is without a doubt the redheaded Lydia.
* Prue Halliwell in ''Series/{{Charmed}}''.
* ''Series/{{Chuck}}'' 's big sister Ellie Bartowski.
* Sharon "Shaz" Granger from ''Series/AshesToAshes'', who despite having a low ranking in CID ([[TruthInTelevision as was actually the norm for woman in 1980s Britain]]) is far smarter than Ray or Chris and often provides valuable information when solving cases.
** As is shown by her [[spoiler: running after an armed shooter in 1x07]],[[spoiler: shooting down a bent copper in her wedding dress in 2x08]] and by her [[spoiler: disarming a armed criminal at gunpoint and turning his weapon against him in 3x08]] she can be just as much a brave Badass as Gene and the others.
* Diana from ''Series/TheSecretCircle''. She is the smartest one of the core group and often takes the lead because of her smarts and capability. Later on, Cassie seems to take the lead more often alongside Diana as Cassie begins to accept her witch ancestry.
* Spencer Hastings from ''Series/PrettyLittleLiars'' is a slight [[DeconstructedTrope deconstruction]]: She's extremely smart, but [[TheBGrade she can't tolerate even the slightest slip.]] Sometimes the pressure of being [[TheSmartGuy The Smart Girl]] gets to her.
** Mona Vandervall also fits the bill, as well as crossing over into [[MagnificentBastard scary-]][[TheChessmaster smart]] category.
** Several minor charcters also answer the criteria - Melissa and Veronica Hastings (it's a family thing) ,Shana Fring and Dr. Sullivan.
* Amelia Folch from ''Series/TheMinistryOfTime''.
* ''Series/{{Voyagers}}'': Jeffrey Jones is quite resourceful and knowledgeable and has brown hair.
* Sam from ''Series/{{Supernatural}}'' went to Stanford and seems to be the researcher, especially in earlier seasons.
* ''Series/WonderWoman'': Wonder Woman helps out by solving complex theoretical scientific problems for Professor Warren in "The Pluto Files"

* Implied in ''Pinball/{{Genie}}'', as the wizard's apprentice is a dark-haired BedlahBabe.

* AlphaBitch Lucy from ''Theatre/{{Thirteen}}'' is a brainy brunette who uses her brains for [[TheChessmaster her own ends]].

[[folder:Video Games]]
* Jennifer Willis, from the original ''VideoGame/{{Splatterhouse}}''.
* Miranda Lawson from ''VideoGame/MassEffect2''.
* The default player character from ''VideoGame/ADanceWithRogues'' has black hair and is really the only character who ever fits the role of TheSmartGuy on your team.
* Morrigan from ''VideoGame/DragonAgeOrigins'', whose intellect is beyond question (though she does seem to spend a lot of it on thinking up more ways to insult Alistair).
* Doctor Delara Auzenne from ''VideoGame/DeusExMankindDivided'' is a renowned expert in Criminal Psychology and serves as a TF-29 Task Force resident psychologist.
* Both April Ryan ''VideoGame/TheLongestJourney'' and Zoe Castillo from ''VideoGame/DreamfallTheLongestJourney''. And the WordOfGod is that the stereotype played (possibly without realization) a role in their design.
* Angela Delvecchio and Lisa Crocket of ''VideoGame/BackyardSports''.
* Rita from ''VideoGame/TalesOfVesperia''.
* ''Franchise/AceAttorney'' has Mia Fey (a defense attorney), Lana Skye (the Chief Prosecutor), and Ema Skye (Lana's younger sister, who is a police detective).
* Mei Ling and Naomi Hunter in ''VideoGame/MetalGear''.
** Solid Snake (160-point IQ, speaks six languages) and Otacon (expert programmer, GadgeteerGenius, creator of Metal Gear Rex) are male examples (although Otacon's hair is more gray-brown than conventional brunet).
* Princess Zelda in her only remotely brunette incarnation, ''VideoGame/TheLegendOfZeldaTwilightPrincess'', is noted by her former tutor to have been an excellent student. She's also the chosen disciple of the Goddess of Wisdom, so it's only logical.
* In ''[[VideoGame/FireEmblemJugdral Fire Emblem: Genealogy of the Holy War]]'', Lana and her {{expy}} Manna are kind, sensitive, and very intuitive {{White Magician Girl}}s. Also Oifaye, who was TheStrategist in the first part and then became the BigBrotherMentor to Celice's group.
* In the second ''Videogame/DarkParables'' game, Literature/{{Cinderella}} is implied to have been this, based on the fact that [[spoiler:her husband constructed a library in her memory.]]
* Stern, the [[TheSmartGuy Material of Wisdom]] from the ''VideoGame/MagicalGirlLyricalNanohaAsPortable'' games. Unlike the light-haired Nanoha whose form she was based on, Stern's hair is dark brown.
* Makoto Nanaya from ''VideoGame/BlazBlue'' plays this trope under the cover of the paradoxical DumbBlonde stereotype. Unlike Noel, who has a hard time picking up on material, Makoto has no appreciation for studying and is a notorious goofball and sexual deviant (though to be fair, she keeps her dirtier fetishes to herself). Where this trope applies is that what she lacks in academic smarts (that's Tsubaki's territory), she more than compensates for in ''[[StreetSmart practical]]'' smarts and common sense, which serve her to no end in her job as an Intelligence officer.

[[folder:Web Comics]]
* Biologist Dr. Jean Poule in ''Webcomic/TheInexplicableAdventuresOfBob''.
* Emily, from ''Webcomic/OurLittleAdventure'', is a straight example. Julie also has plenty of brains and brown hair, but it's apparently [[http://danielscreations.com/ola/comics/ep0134.html not her real hair color]].
* In the RemixComic version of ''Webcomic/JetDream'', Marlene is even brainier, described as one of the best people in the Western world at [[ForScience Doing Science]].
* The {{nerd}}y Ruby of ''Webcomic/StickyDillyBuns'' has what seems to be the only university-level education in the cast. Her intelligence may sometimes seem like an InformedAttribute, but she's stuck with being the book-smart, occasionally snarky contrast to her blonde sister Amber, and she does occasionally display some mental agility. So she lives this trope, complete with glasses.
* ''Webcomic/{{Sunstone}}'' has the bookish, raven-haired Allyson.
* ''[[{{Webcomic/morphe}} morphE]]'' features Billy Thatcher a brunette chess champion who serves as the brains of the group and would probably be voted "Most likely to be shot by Amical" in the current seedling yearbook.
* ''Webcomic/AngelMoxie'': Riley, the brunette member of a BeautyBrainsAndBrawn trio. Loves school, programs computers, and builds her own weapons from scratch.

[[folder:Web Original]]
* Parodied by WebVideo/TheNostalgiaChick, who thinks she knows everything but is really a KnowNothingKnowItAll. Played straight by MsExposition BBF Nella and MadScientist Dr. Block.
* WebVideo/LaciGreen, pint-sized sex guru from the west coast.
* Thalia, Calliope, and the rest of the Muses in ''Literature/ThaliasMusings''.
** Also, Athena, the Goddess of Wisdom, Crafting, and Battle Strategy.
* ''WebVideo/TheAutobiographyOfJaneEyre'': Jane Eyre is portrayed by a dark-haired woman in this SettingUpdate adaptation. Jane says she has always been very good at school, loves books and reading and considers herself a smart girl. She's based on a very down-to-earth character.
* Like the [[Disney/BeautyAndTheBeast Disney version]], Belle in ''WebVideo/UniversityEverAfter'' is an intelligent, well-read brunette.
* Gaea from ''Franchise/{{Noob}}'', dark or lighter brown [[AdaptationDyeJob depending on the media]], local ManipulativeBastard.
* ''Literature/WhateleyUniverse'': Abracadabra (Bethany Tarvetti). She has [[http://whateleyacademy.net/index.php/original-timeline/371-the-three-little-witches long straight black hair]] and is taking high-schooler courses as a Junior High student.

[[folder:Western Animation]]
* The titular character of ''WesternAnimatiom/TheAdventuresOfJimmyNeutronBoyGenius''. He's got brown hair and is a ChildProdigy GadgeteerGenius prone to LittleProfessorDialog, though admittedly he lacks actual common sense.
* ''Franchise/AlvinAndTheChipmunks''. Jeanette of the Chipettes is both the brainy one and the brunette in the Chipette trio.
* [[TheDragon Azula]], from ''WesternAnimation/AvatarTheLastAirbender'', is [[MagnificentBastard terrifyingly]] intelligent and a ManipulativeBastard par excellence. And [[TheLancer Katara]] isn't dumb, either, though her brother Sokka is [[TheSmartGuy "the Idea Guy"]] of the Gaang. Of course, all but one character in the show are or were dark-haired.
* ''WesternAnimation/DanVs'':
** Elise is shown to have a very high intelligence, given that she is a secret government agent; however, she also has traits of a FieryRedhead.
** Dan himself also counts somewhat; he is shown to be [[BrilliantButLazy well read, but lacks any common sense]].
* ''WesternAnimation/{{Daria}}''. Daria Morgendorffer is a combination of this trope and DeadpanSnarker. It helps make her a famous [[TheSnarkKnight Snark Knight]].
* Bushroot's HotScientist love interest Dr. Rhoda Dendron from his origin story on ''WesternAnimation/DarkwingDuck''.
* Dipper Pines from ''WesternAnimation/GravityFalls'' is one. His twin sister Mabel technically counts too, but she's more of a GeniusDitz.
* Mike Chilton in ''{{WesternAnimation/Motorcity}}''. He's a bit more subtle than other examples, but he is a strategic genius from his cadet training. He often relies on his IndyPloy, however.
* On ''WesternAnimation/{{Recess}}''
** Gretchen and Spinelli invert their typical hair tropes, as Spinelli (brunette) is fiery and Gretchen (redhead) is brainy. Gretchen ''did'' have black hair in the pilot, though.
** T.J. subverts this, as he's quite ditzy when it comes to academics, but is a genius when it comes to his schemes on the playground.
** Miss Grotke plays this trope straight.
* Velma Dinkley of ''Franchise/ScoobyDoo'': Throughout her various incarnations, Velma is usually portrayed as a highly intelligent young woman with highly specific interests in science (which in the Scooby and Scrappy Doo series leads her to pursue a career as a NASA research scientist) or merely being very well read on obscure fields, such as ancient Viking writing (as in the third Scooby Doo series ''WesternAnimation/TheNewScoobyDooMovies'').
* Sandy from ''WesternAnimation/SpongebobSquarepants'' is a brown furred squirrel and, along with Plankton, the most intelligent of the main cast.
* Connie from ''WesternAnimation/StevenUniverse'', a black-skinned version.
* Inverted on ''WesternAnimation/ThePowerpuffGirls'' where the red-headed Blossom is the brainy one, while the brunette Buttercup is the aggressive spitfire. (Bubbles is still the DumbBlonde, though.)
* ''WesternAnimation/ReadyJetGo'': Sean and his mom are both know a lot about science, and they both have brown hair. However, Sean's mom's hair is a bit reddish.
** Mitchell counts too.
* ''WesternAnimation/TheLoudHouse'' has Lisa Loud, who, despite being the second youngest of the family, is also the most intelligent of all the siblings.
* ''WesternAnimation/TheSimpsons'': an episode's B-plot focused on Lisa joining the debate team and ending up dyeing her hair brown to prove that they didn't take her seriously before, due to being blonde. Megan, the girl who made fun of Lisa for being blonde, is presented as one of these.
* ''WesternAnimation/TotalDrama'' has Noah (book smarts), Courtney (legal smarts), Cody ([[TechnoWizard mechanical smarts]]) and Alejandro ([[ChessMaster people smarts]]).
** Heather specifically lampshades this in ''Action'' where she was looking for new hair and said: "I'm too smart to be Lindsay blonde, but Courtney's hair would be perfect."
** ''WesternAnimation/TotalDramaPresentsTheRidonculousRace'' has the Geniuses who both have dark hair.
* ''WesternAnimation/ThundarrTheBarbarian'': Besides her knowledge of magic and ancient history, Ariel also has more common sense than anyone else on the show, hero or villain. She has dark hair due to her Asian ancestry.
