[[caption-width:300: Your parents won't believe you when you tell them about the Trunchbull.]]

->''When we grew up and went to school\\
There were certain teachers who\\
Would hurt the children any way they could\\
By pouring their derision\\
Upon everything we did\\
Exposing every weakness\\
However carefully hidden by the kid...''
-->-- "The Happiest Days of Our Lives", PinkFloyd, ''TheWall''

->''"What is this place, Douchebag High? What kind of teachers talk like that? You'd get your ass fired if you talked like that!"''
-->-- '''TheNostalgiaCritic'''

->''"Now if I hear one more peep out of any of you scrubs, someone's going to get... '''A LOVE PUNCH!!!''' Any questions?"''
-->-- '''Miss Kisskillya''', ''{{Detention}}''

So you made it past the evil bus driver, avoided the cafeteria lady with her MysteryMeat, and dodged the [[JerkJock bully in the schoolyard]]. You're safe now, right?

Guess again.

Now it's time to face... ''that'' teacher.

You know which one. The teacher who singles you out for ridicule and humiliation. The one who openly mocks you in front of the rest of the class. The one who tells you he ''wants'' you to fail because you don't ''deserve'' to get into high school/college/grad school. He'll flunk you for breathing, then craft you a make-up exam that ''no one'' can pass, just to get you coming and going. He's the SadistTeacher, the education system's answer to DrillSergeantNasty.

Sometimes he hates all children and sometimes it's just one special child who becomes the target of his rancor. Of course, if he hates all children, ''why'' he got a job involving them so much is never explained. Either way, he is as cruel as he can possibly be and not leave marks. In extreme cases he actively tries to destroy a child's spirit and reputation, sometimes going so far as to falsify evidence that the student has done something absolutely horrendous. And [[VillainWithGoodPublicity because he's a ]]''[[VillainWithGoodPublicity teacher]]'', [[CassandraTruth it would take a miracle to make anyone doubt his word]].

They're also almost always the most suspicious of the OrdinaryHighSchoolStudent with a SecretIdentity and determined to uncover the {{Masquerade}}. Worse, maybe they ''have'' discovered it, and in addition to all your other problems of saving the world, you have to keep them from proving it.

For a child, he is possibly the worst enemy one can face.

Principals, counselors, and [[DrillSergeantNasty coaches]] are no exceptions to this trope. And don't think you'll escape him/her upon graduation -- waiting for you at college or university is DeanBitterman.

Obviously designed to tap into the hatred every student feels for those given charge of their life for eight miserable hours of tedious torture every day for twelve years; just making a character a schoolteacher is a good KickTheDog (unless they're playing into an audience [[HotForTeacher teacher fetish]]), so why not take it as far as possible?

Sadly, all too often the SadistTeacher is a case of TruthInTelevision -- even inspired by [[CreatorBreakdown the writer's own personal experiences]] -- but some examples are more intense than any ''actual'' teacher could be without the Board of Education having them sacked within a matter of weeks. (Well, the ''real'' problem is the fact that getting rid of these guys may take months or years in America at least, thanks to the absurdly powerful teacher's union...)

Although, sometimes, it's a bit of a stupid plan, because if you flunk, he/she'll ''have'' to see the student's face again. Not really bright up there, right, Mr(s). Sadist Teacher?

See SternTeacher for their more reasonable counterpart. May overlap with EvilTeacher. Contrast HippieTeacher, MisplacedKindergartenTeacher, and BadassTeacher.

If you can't get the school board to put a stop to the abuse, your best hope is to enlist a {{Bully Hunter}}.

!!Examples:

[[foldercontrol]]

[[folder:{{Anime}} and {{Manga}}]]
* Taken to its literal extremes in the different teachers for the book, manga and film versions of ''BattleRoyale''. In the manga version at least, the "teacher", who is also the host of "the Program", shoots one student twice when he raises a furor over the fact that said teacher raped his caretaker, then sinks a knife into another student's head for talking. [[spoiler:In all three versions, when some of the students are about to escape the island, they make a point of finding and killing the "teacher".]]
** In the manga, there's an interlude during the Sugimura/Kotohiki section that talks about Jaguar, a gym teacher they had. Jaguar was a total jerk, challenging the students to martial arts duels and humiliating and/or hurting them when they wouldn't fight back. [[spoiler:He eventually challenged [[AxCrazy Kiriyama]], who plucked out and squished his eye.]]
* The Kirby anime series has King Dedede setting up a school. The teachers are required to wear this hat while teaching. Their lessons included math (throwing students across rooms for wrong answers), science (splitting plutonium!) and so on... http://www.youtube.com/watch?v=18X_EOpdIrI&NR=1
* [[PlayingWithATrope Played with]] on ''{{Yu-Gi-Oh GX}}'' with Professor Chronos. In addition to being as biased as [[HarryPotter Snape]] to the students in his dorm, Chronos has a personal grudge against Judai for publicly defeating him in a duel and thus devoted Season 1 to trying to get Judai kicked out of school. However, Chronos has had his moments that prove deep down, [[JerkWithAHeartOfGold he really cares about his students]]. [[spoiler: He also manages to combine a HeroicSacrifice with a RousingSpeech to raise his students' morale, just before getting beaten by one of the Shadow Riders.]]
** Professor Cobra (or Thelonius Viper), on the other hand, is a total wanker, forcing students to duel so he can steal their life energy to resurrect his son.
** And honestly, Principal Samejima/Chancellor Sheppard isn't much better, since he ''employed'' said person. At least he [[LampshadeHanging knows and regrets]] that AdultsAreUseless.
** The first seven volumes of the original ''{{Yu-Gi-Oh}}'' have: a [[TheVamp Vamp]]}} who dates men and breaks their hearts for the hell of it, a sadistic guidance counselor who regularly mocks the lower-scoring students and tried to stomp on Anzu/Tea's electronic keychain, and a gym teacher who bullies Bakura because of his hairstyle. All three found themselves on the receiving end of karma in the end, though (the Vamp had her makeup peeled off, revealing how ugly she really was to the whole class; the counselor was revealed to be bald and wearing a toupee; the gym teacher got turned into an RPG figurine by Dark Bakura).
*** Though it should be noted that the gym teacher got turned back once Yami Yugi beat Bakura, and goes back to being his old {{Jerkass}} self.
* Brilliantly subverted in Osamu Tezuka's ''BlackJack''. A sadistic Maths teacher terrorizes his "weakest" student to the point of traumatizing him, but is actually a [[JerkWithAHeartOfGold good person at heart]] [[SternTeacher who only wants to toughen the kiddo up]]. [[spoiler:Actually, the boy almost dies in a street accident that he got in [[WhyDidItHaveToBeSnakes because he was too distraught by his phobia of the teacher]], and the man feels [[TheAtoner so guilty when he finds out]] that he attempts to kill himself and give the money of his health insurance to the kid's mother so Dr. Black Jack can operate on the boy. In the end, Black Jack saves both of them]].
* Sister Grace, the St. Paul College principal in ''CandyCandy,'' straddles the line between this and SternTeacher.
* Subverted in ''{{Rosario to Vampire}}'' by [[spoiler: Kagome Ririko, a lamia]] and literal sadist along with [[spoiler: Hitomi Ishigami whose sadistic tendencies really shine after she's fired]].
* In ''KodomoNoOmocha'', Sengoku-sensei has an almost obsessive hatred of Akito, going to great lengths to make the kid miserable, even hit him once. Turns out it's [[FreudianExcuse because Akito reminds him of the kids who used to bully him when he was younger]].
* Just before the Trunks saga of ''DragonBallZ'', [=ChiChi=] hires a private tutor for Gohan who turns out to be one of these. Mr. Shu is a raging asshole who repeatedly [[KickTheDog Kicks The Dog]] by calling Goku worthless as a father and even makes poor Gohan bleed. When [=ChiChi=] finally finds out about how much of a sadist he is...[[MamaBear let's just say it doesn't end well for Shu]].
* {{The Dreaming}}'s Avril Merriweather, the first headmistress of Greenwich Private College, punishes her students by locking them in cupboards and coffins.
* Played for laughs in ''FullMetalPanic'' with the gym teacher. He genuinely hates Sousuke, but Sousuke mistakes his malice as respectable boot-camp teacher behavior. Whenever the teacher goes on a tirade against him, Sousuke treats him like an officer, which in turn is taken like smart aleck behavior. HilarityEnsues.
** And Sousuke's assumption that such sadistic malice is ''normal'' for a teacher makes ''him'' one as well. Just look at [[TrainingFromHell the way he trained the school's gentle, girly rugby team]]. Well, [[BrainwashedAndCrazy you can't say it didn't work...]]
* ''JigokuShoujo'' follows a group of supernatural beings who can be "hired" to send one person bodily to Hell, at the cost of the contractors' soul upon death. Sadist Teachers are some of their more frequent victims, ranging from a literal sadist who felt sexual pleasure from humiliating one of her female students, to an extremely strict teacher who kept a notebook full of details about the students' misbehavior (which, it turns out, was actually blank).
* Mr. Iwamoto and Mr. Akashi from ''YuYuHakusho''. Why Mr. Takanaka, the principal (and decent guy) hasn't fired their asses, the world will never know.
* Miss Minchin from ''ShokojoSera'' makes her novel counterpart look positively benign. Not only is she greedy and unjust, but she resents the slightest threat to her [[SmallNameBigEgo inflated self-esteem]], and has serious anger management issues.
[[/folder]]

[[folder:{{Comics}}]]
* In the Israeli comics ''Zbeng!'', about the school one of the main characters, is, of course, this trope taken to the absurd, a green dress wearing monster named Anuga Zaafani. In her own personal book, it is even showed how she drove to extremes Peter Parker (literally drove him up the wall), Clark Kent (green dress... guess what material), Garfield the Cat (decided to take a vacation in Thailand), and her day schedule consists of waking up, falling asleep, and eleven cases of shouting in between. In the end, where everybody is supposed to have their graves shown -- she is alive and well among everyone else's graves. Naturally, she'll bury them all.
*Chalky, the cadaverously evil teacher with an impressive collection of canes and a love of terrifying schoolchildren and other teachers, from the newspaper cartoons by Giles.
[[/folder]]

[[folder:{{Film}}]]
* In the more recent Jamie Lee Curtis/Lindsay Lohan version of ''FreakyFriday'', Lindsay Lohan's character had a mean teacher who always put her down in class even when she gave an intelligent answer. Curtis' character [[CassandraTruth didn't believe her]] until they get [[FreakyFridayFlip their bodies swapped]]... and suffers at his hands, only to recall that he is a guy she rejected back in the day.
* Miss Edelson, Agent J's 3rd grade teacher in ''MenInBlack'', who turned out to be an alien from one of Jupiter's moons.
* Professor Terguson in ''BackToSchool'', harassing college students over the Vietnam War.
-->'''Prof. Terguson''': Is she right? 'Cause I know that's the ''popular'' version of what went on there. And a lot of people like to believe that. I wish I could, but I was ''there.'' I wasn't here in a class room, hoping I was right, thinking about it. I WAS UP TO MY KNEES IN RICE PADDIES, WITH GUNS THAT DIDN'T WORK! GOING IN THERE, LOOKING FOR CHARLIE, SLUGGING IT OUT WITH HIM, WHILE ''PUSSIES'' LIKE YOU WERE BACK HERE PARTYING, PUTTING HEADBANDS ON, DOING DRUGS, AND LISTENING TO THE GODDAMN BEATLE ALBUMS! AAAAAAAAAAH! AAAAAAAAAAAAAAAAH! AAAAAAAAAAAAH!
* The tormenting teacher is also present in Ingmar Bergman's aptly named movie ''Torment'' from 1944. The sadistic Latin teacher is even nicknamed Caligula.
* The title character in ''Teaching Mrs. Tingle''.
[[/folder]]

[[folder:{{Literature}}]]
* Another literary/film example: Principal Trunchbull of ''{{Matilda}}'', reputedly used by RoaldDahl as a surrogate for all the cruel tutors he had over the years. Her treatment of children is so extreme and outlandish, [[CassandraTruth no kid's parents will believe the truth]] when they are told. (She cites Wackford Squeers from ''Nicholas Nickelby'' as inspiration: "''He'' knew how to handle the little brutes, didn't he!") [[spoiler:Not to mention the way she treats her ''own niece'', the more benign teacher Miss Honey...]]
** In the film, it's implied that Trunchbull [[spoiler: had a hand in Miss Honey's father's death. In a flash back, Miss Honey says that all the reports say that he committed suicide, which is followed by a scene of little Honey sitting on a swing with Trunchbull walking up behind her. During this scene, you hear a voice over of Matilda say, "I don't think Magnus killed himself." Then you hear Honey say, "I don't think he did, either."]]
*** The book is not exactly the same but that implication is definitely there:
---->"I know what you're thinking," Matilda said. "You're thinking that [[spoiler:the aunt killed him and made it look as though he'd done it himself]]."\\
"I am not thinking anything," Miss Honey said. "One must never think things like that without proof."
* Captain Lancaster in ''DannyTheChampionOfTheWorld'' is a more realistic example. He's obviously based on one of Roald Dahl's actual teachers, Captain Hardcastle, described in his autobiography ''Boy''.
* The unnamed Head of Experiment House in ''[[{{Narnia}} The Silver Chair]]'', inspired by C.S. Lewis' own unfortunate experience with his first headmaster.
** More than an actual SadistTeacher, the Headmistress seems to be a ShoutOut to the HippieTeacher type. She thought that everything could be solved by merely talking to the kids, even the bullies.
*** And the book is even older than the hippie movement.
* Miss Heaton ("Hawkeye"), Miss Simpson ("Slim") and Miss Stamp ("Adolfa") in the ''ConfessionsOfGeorgiaNicolson'' series.
* Schoolteacher from ''{{Beloved}}''. Owns. This. Fucking. Trope.
** Not really - schoolteacher was a [[CompleteMonster complete monster]] without question, but he wasn't the slaves' teacher.
* Brother Leon from ''TheChocolateWar''. He fails David Caroni, a straight-A student, to show Jerry what he's willing to do if the chocolates aren't sold.
* If your kids ever think Dame Snap from the ''FarawayTree'' books is unnecessarily mean, tell them she originally was known as Dame ''Slap''.
* Most, if not all, of the teachers in the ''CaptainUnderpants'' books. The most notable ones are Mr Krupp, the principal, [[spoiler:(who's also Captain Underpants, due to a prank gone wrong)]] and Mrs Ribble, George and Harold's teacher, [[spoiler: who undergoes a FaceHeelTurn in the fifth book after becoming the supervillain Wedgie Woman. At the end, George and Harold hypnotise her into being nice, which sticks.]] There was also Professor Poopypants, who was actually a nice person [[spoiler:until the teasing about his name drove him to construct a giant robot and force everyone to have silly names like his.]]
* Subverted in ''The Demon Headmaster'' -- the writer claimed that the reason the Headmaster can hypnotize people is because it's the only way she could think of to ensure that the parents never realized what was going on.
* Miss Minchin from Frances Hodgson Burnett's ''ALittlePrincess''.
* Wackford Squeers from ''Nicholas Nickleby'' by CharlesDickens, who makes this trope OlderThanRadio.
** Another Dickens example would be Mr. Creakle, of ''DavidCopperfield''.
* Mesaana from Robert Jordan's ''{{The Wheel of Time}}'' series turned to the Dark Side sometime after being turned down for a respected research position and was relegated instead to teaching.
* In Chip Kidd's novel ''The Cheese Monkeys'', Professor Sorbeck straddles the line between this and SternTeacher. A notable example: the class is Graphic Design, the assignment is to illustrate a word with appropriate form for the word's content. A student presents his rendition of "HOT" made of match-heads stuck to posterboard with rubber cement. Sorbeck scowls at this and has the student touch it. Is his finger warmed? No? So it's not very hot, is it, which would make it an F. The student loses some composure -- at which point Sorbeck tosses him a cigarette lighter and points out that he can remedy the situation. After a little browbeating, the student lights his work, resulting in a brief, intense conflagration and a large scorch mark on the wall. Sorbeck blandly comments that it was an A while it was going.
* In the StephenKing novella "The Body" (and its movie adaptation, ''StandByMe''), Chris Chambers tells Gordie how he stole their class's milk money, had a change of heart and tried to return it, only to have their teacher steal the money in turn and then blame it on Chris, whose reputation for criminal mischief came back to haunt him.
* Mr. Jonas, in Richard Llewellyn's ''How Green Was My Valley''.
* Lucy Maud Montgomery's heroines almost always fall victim to this teacher. Probably the worst offender was Miss Brownell, of ''Emily of New Moon'' fame. Her worst offense was taking Emily's manuscripts in class and reading aloud Emily's poems in a mocking voice, with snide comments, and occasionally accusing Emily of passing off other author's works as her own. When Emily refused to apologize for writing poetry in class, Miss Brownell came to New Moon and tried to convince Emily's guardian to force the girl to ''kneel'' to Miss Brownell and apologize.
** The TV series topped her with an even worse male teacher who made racist remarks and beat an Indian boy for not answering him fast enough, then beat Emily when she tried to stop him.
* Professor Snape from the ''HarryPotter'' stories. Half of it comes from a bias for the Slytherin students and against the Gryffindor students, and half of it comes from disliking Harry personally, due to Harry's father's frequent bullying of him during ''their'' school days. Of course, he's gotten PetTheDog moments. [[spoiler:Although it was put into strong doubt in Book 6, it was finally revealed in the final book that Snape is an AntiHero who was best friends since childhood with Harry's mother Lily.]]
** Another ''HarryPotter'' example would be Dolores [[TheUmbridge (The) Umbridge]] from ''Order of the Phoenix''. Unlike Snape, she's a SmugSnake who mainly gets to KickTheDog and, on more than one occasion, cross the MoralEventHorizon.
* Mrs. Gorf in the first book of Louis Sachar's ''WaysideSchool'' series turns her students into ''apples'' when they do anything wrong. Including sneezing in class. The students manage to outsmart her by forcing her to turn them back into humans and tricking her into turning herself into an apple, which [[AuthorAvatar Louis]] then unknowingly eats.
** Wendy Nogard in ''Wayside School Gets a Little Stranger'' is a more subtle (but even more insidious) example: while she appears to be a sweet, considerate teacher, she uses her mind-reading abilities to humiliate and turn her students against each other -- all without ever compromising her [[StepfordSmiler "nice teacher" facade]]. An example of this is when, during a homework-checking session, she deliberately calls on the one student who has the incorrect answer for each question, and using the resulting slew of wrong answers to retract her promise of no homework for that day. Every student ends up hating all the others for being idiots who cheated him/her out of a homework-free afternoon, even though in reality none of them missed more than two questions on the assignment.
** Wayside School had terrible luck with their substitute teachers. Their first one, Mr. Gorf, was actually the son of Mrs Gorf and had the freakish ability to steal the voices of people through his ''nose''! Which had three nostrils! Then, when he had stolen the students' voices, he called their parents up and used their voices to say terrible things, making their parents think the kids hated them. Their second substitute, Ms Drazil, seemed very nice at first but turned out to be the yard teacher Louis's old teacher and according to him had humiliated him over the state of his nails and put a wastebasket over his head so he couldn't read the board and failed him as a result of not being able to answer the questions. While she never does any of this to the Wayside kids, she does resume her tyrannical control over Louis which is enough to make the students hate her. Oh, and it's later revealed that she kept a blue notebook with information on various students she held grudges with and upon getting a lead on a girl who escaped, tracks down said girl (now a successful dentist) and breaks into her house yelling that the girl has homework to do. And the girl was ''expecting'' something like this to happen, even keeping a suitcase and gettaway boat for the occasion. Even the regular teachers aren't always safe. One chapter in ''Sideways Stories from Wayside School'' comments that every nice teacher has a mean teacher wanting to break out and illustrates this by showing a class in which Ms Jewel's "mean teacher" breaks out and threatens to dump pickle brine on a student for being unable to answer three questions (to be fair, the questions were "what's seven plus five", "what's the capital of England", and "how do you make pickes" and she is cured by having brine dumped on herself). The principle, named Mr. Kidswatter, is apparently a holy terror and students dread going to his office.
* Danish author Hans Scherfig's novel ''The Stolen Spring'' takes place in a school where almost every teacher is a sadist, the worst being the main characters' Latin teacher, Professor Blomme.
* Eliza Jane Wilder from the ''[[LittleHouseOnThePrairie Little House]]'' books, whose pet was TheLibby Nellie Oleson. Nellie helped foster a dislike of the protagonist Laura, partly because they were girlhood enemies and partly because she was smitten with Eliza Jane's brother, Almanzo. She starts out sickeningly sweet, but Eliza Jane was apparently very bitter that Pa Ingalls, who was on the school board, had very little to say about her school. Her bitterness towards Pa manifests itself as bitterness towards Laura, but when she punishes Carrie unfairly (even though another girl was equally guilty, Eliza Jane let her off) and Carrie looks as though she's about to faint, Laura gets angry, offers to do Carrie's punishment herself, and her popularity with the boys at school basically leads them running her out of town. Then Laura marries her brother.

[[folder:LiveActionTV]]
* Principal Craft of ''SabrinaTheTeenageWitch''.
** An episode of the same series had the one-off character Mr. Rockwell, a rude and incredibly sadistic maths teacher (for example, after warning students that anyone who was late to the test by even a ''second'' would fail, he shuts the door and taunts a student who was one second late due to helping a fellow student ''in a wheelchair''). Sabrina asks her aunts for help and they eventually get him to stand trial in an Other Realm court. Rockwell is eventually sentenced to his worst nightmare: remaining a maths teacher for the rest of his life. When Sabrina complaints about the effect this ends up having on those unfortunate to be his students, Zelda handwaves this by claiming he teaches them a "valuable lesson". Yay.
* And what would an entry on the Wiki be without the mandatory ''BuffyTheVampireSlayer'' example? Two words: ''Principal Snyder''.
** At least he does explain why he's a teacher, despite hating kids. 'Somebody has to keep an eye on them.'
* Comedy example: Mr. Sweeney from ''NedsDeclassifiedSchoolSurvivalGuide''. In one episode, Ned asks Mr. Sweeney to explain how a science fair diorama should look. In response, Mr. Sweeney reaches behind his desk, takes out an elaborately detailed diorama explaining why Ned is likely to get an "F" on his science fair project -- and shows it to the whole class.
** To be fair, he does soften up over time, with the eventual result being that Sweeney was only sadistic from Ned's point of view and Ned usually deserved the grades Sweeney gave him.
** Sweeney also subverts this in the GrandFinale, where he admits to Ned (who is hanging upside in a tree) [[spoiler: that Ned was his favorite student and enjoyed his antics. And leaves him hanging in the tree.]]
* Back in 1986, Christopher Lloyd had a field day playing the gleefully sadistic Professor B.O. Beanes in "Go to the Head of the Class", a memorable, hour-long episode of StevenSpielberg's ''[[http://www.imdb.com/title/tt0511097/ Amazing Stories]]''. One fan's excellent review, available [[http://www.x-entertainment.com/articles/0955/ here,]] goes into loving detail and includes numerous clips that ''must'' be seen. ''Especially'' the clip wherein hapless high school student Peter Brand is forced to ''"meet the Misters!!"''
* One Maurice Bronson in ''GrangeHill'', the classic example.
* Ms. Francine Briggs from ''ICarly'' and the teacher in the ''iGot Detention'' episode.
* Mrs. Hayfer from ''DrakeAndJosh'' is considered an overall nice teacher by Josh, but she often nitpicks at Drake for his poor performance, even going as far as to continuously say she hates him out loud.
* Chuck Noblet in ''StrangersWithCandy'', particularly to Jerri. [[WordOfGod Word Of]] StephenColbert says he does this because he's so repressed and secretive, and resents her for trying to find things out and figure out her life.
* Herkabe from ''MalcolmInTheMiddle''. (It's not surprising that an important character is a teacher who's a sadist -- how many characters on that show ''aren't'' sadists?)
* Haresh Chandra appears to be this when he first appears as the new headteacher in ''TheSarahJaneAdventures'', then it turns out he is the new regular character Rani's father (much to the dismay of ClassClown Clyde who has an obvious crush on Rani). He's also a nicer person when he gets home, and Rani and her mother Gita make fun of him for his stern streak.
* Reuben Tedesco in the ''FamilyTies'' episode "The Harder They Fall." Insufferably rude and insulting to parents as well as students, he provokes both Keaton parents to violence.
-->'''Mother 1''': My son says you're always insulting him in front of the other students. You call him names.\\
'''Tedesco''': Who's your son?\\
'''Mother 1''': Larry Morgan.\\
'''Tedesco''': Larry the Loser? Madam, your son is a pimple-faced liar!
And:
-->'''Mother 2''': My daughter Cindy so enjoyed reading ''The Little Prince''. Is there anything else you could recommend for her?\\
'''Tedesco''': Yes, I'd recommend she lose about forty pounds. You could lose about thirty yourself.

[[folder:{{Music}}]]
* Pink's teacher in the RockOpera ''TheWall'' by PinkFloyd, as quoted at the top of the page. Also, by his own admission, ''Roger Waters''' experiences were something like this.
** Ah, but in the town, it was well known when they got home at night their fat and psychopathic wives would thrash them within inches of their lives!
*** The teacher is portrayed in a slightly more sympathetic light in ''The Final Cut'', in which we learn that he is a bitter veteran of the WorldWarII who takes his anger out on the children, who he perceives as whiny and ungrateful.
[[/folder]]

[[folder:{{Theater}}]]
* One presumes that Mrs. Thistletwat in ''AvenueQ'' is no better to her students than she is to her teaching assistant.
* In ''A Chorus Line'' Diana Morales recounts the story of her acting teacher at the High School for Performing Arts, Mr. Karp, who turns on her after she questions his approach, and allows the other students to humiliate her.
** According to [[LooneyToons This Troper]]'s theatre contacts, "Mr. Karp" was a thinly-disguised version of a real teacher under whom Priscilla Lopez (the original Morales) suffered, making this also a RealLife example.
* All of the teachers in the musical ''Spring Awakening'' are caricatures of this trope.
** This troper thinks that the original play version makes them seem even more ridiculous.
[[/folder]]

[[folder:RealLife]]
* Issac Newton apparently hated being made a professor and deliberately set up his classes so that no student had any chance of passing in order to prevent anyone from showing up.
* ThisTroper could [[TroperTales tell you all about]] his sadistic language teacher, if he wasn't completely choked with rage at the memory. Compared to him, most fictional examples pale.
* ThisTroper went through school with an undiagnosed Autistic Spectrum Disorder, and thus ended up as a target of bullying teachers fairly often. One especially egregorious example includes the second grade teacher who screamed at me for "talking like a kindergardener" and "making stupid comments" when I answered one of her questions; dragging me around the room by the arm to show me all of the students who were able to understand a math problem that I couldn't handle; and screaming and slapping the desk when I was caught hiding a book under my desk.

[[folder:VideoGames]]
* Ishikawa-sensei from ''{{Yumeria}}''.
* Souichirou Kuzuki from ''FateStayNight'' is just a strict history teacher by day, [[spoiler: but at night, he turns BadassNormal and kicks ass for his Servant, Caster. It doesn't help that he was raised and taught to be a perfect assassin and can shatter swords with his fists (though they were magically empowered by Caster).]]
** He's not actually sadistic in any sense though. The game actually makes a point to note that the students respect his impartiality and seriousness. It turns out he's actually [[spoiler: completely amoral and has no qualms about helping Caster kill pretty much everyone in the city, but he doesn't enjoy it either. You might even go so far far as to call this a subversion, considering his popularity with all the students, including the main characters.]]
* Several members of the faculty at Bullworth Academy in ''{{Bully}}'', Mr. Hattrick being the worst.
* ''{{Persona 4}}'' has Mr. Morooka, a.k.a "King Moron", a rather snobbish (and hideous) man with a grudge against women as well as the main character. He treats his students rudely (putting the main character on his "Shit List" within minutes of meeting him), and has a tendency to get drunk on school fieldtrips. Still, his accusations of the Main Character being a horny bastard [[ChickMagnet may actually have some truth behind it]].
* The teacher seen in the intro movie of ''{{Heart of Darkness}}'', wherein he puts Andy in a hole and asks him if he's afraid of the dark...
[[/folder]]

[[folder:WebComics]]
* Mr. Dover from ''CollegeRoomiesFromHell!!!'' There's more to him than the trope, but he certainly enjoys nurturing his students' impressions of him.
* Kat from ''Webcomic/SequentialArt'' is a photographer by profession; she was once hired to take school photographs -- and horrified to discover that the teacher who had put special care into humiliating her in fifth grade was the principal of the school. Their adversarial relationship was promptly renewed, and it's highly probable that Kat may have driven the woman to her fatal heart attack.
** Though considering that it was the teacher who did all the renewing of hostilities, up to and including trying to threaten Kat's job, Kat's satisfaction at the teacher's demise is fairly understandable. (Though the woman's current students were [[DingDongTheWitchIsDead far more overjoyed]].)
* Keiko Keshin from ''TriquetraCats'' is an evil vampire sadistic Principal, using her position to torture students, those who survive the torture are made into vampire henchmen.
* In ''ElGoonishShive'', the science teacher (who hasn't actually been seen in a while) quite likes watching his students suffer.
** Likewise, this history teacher giving Grace a hard time, starting [[http://egscomics.com/?date=2008-01-18 here]].
*** Every time I see the latest comic (You Mess With The Raven, You Get The Beak) I hate that guy more and more.
**** Update: He's snapped. I mean, seriously, he's lost it. Go look. [[http://www.egscomics.com/?date=2008-02-27 It's up now]].
***** While he ''is'' sadistic, he's mostly just really really weird due to being half human, half immortal (called an "elf" in-story), and his sadistic nature comes from that.
****** And then [[http://www.egscomics.com/?date=2009-06-18 this happens]]. Discuss amongst yourselves, class.
** Conversely, the math teacher offered a subversion -- although he initially seemed like he was going to be one of these, he revealed he was actually fooling around and in fact turned out to be quite nice.
* In a surprising move, the titular character from ''DominicDeegan'' is a subversion of the SadistTeacher trope; yes, he teaches a very difficult class, but his reputation precedes him, and he's in fact a very approachable person.
** How is that a subversion, exactly? Not every case of a teacher ''not'' being a sadist is a subversion.
* The SadistTeacher in ''YuMeDream'' is actually a nun.

* Usually subverted and/or averted in the WhateleyUniverse, even though the stories center around the SuperHeroSchool Whateley Academy and some of the teachers are retired ''supervillains''. Erik Mahren, the ex-Marine range master on Range 4 (the heavy weapons range) was notorious for being absolutely ruthless when it came to weapons safety, but the net result of that was that no students were hurt or killed on the ranges in his entire tenure as rangemaster. The Reverend Darren England has gone after a couple students when he sensed their connection to planet-threatening evil...but went ''way'' over the line when he hired Syndicate hitmen to help some of his minions try to assassinate one such student (who happens to be one of the good guys).
** The closest thing to the "sadist teacher" archetype seen at Whateley so far would actually be Amelia Hartford, though she ends up being more of a highly placed ObstructiveBureaucrat or DeanBitterman due to not actually having a teaching position (that we've seen thus far).
* ''{{XIN}}'' anyone? The school rules are practically built around allowing teachers to do whatever it takes... violent or non-violent... to keep order in class. Including brutalising students into bloody shivering pulps... for [[DisproportionateRetribution homework violations...]]

* Mr. Crocker from ''{{The Fairly OddParents}}''. Besides his fairy-hunting obsession, he also takes a sadistic glee in handing out "F" grades to his students. In TheMovie, he actually manages to use magic to change history and make himself EvilOverlord of a {{Dystopia}}n world.
* Ms. Bitters from ''InvaderZim'' is an extreme example. She's a NietzscheWannabe who not only hates her students (especially Dib and Zim), but everyone and everything in the world. "Children, your performance was miserable. Your parents will all receive phone calls instructing them to love you less now."
** Her design is almost exactly the same as the teacher in ''Squee'' (also by Jhonen Vasquez), who's just as sadistic, and intentionally teaches the students wrong information.
* Inverted in ''BeavisAndButthead'' Mr. Van Driessen, the boys' [[GranolaGirl overly spiritual]] social studies teacher, apparently can't bring himself to discipline anyone and gets steamrolled by their pranks time and time again.
** Then played straight by DrillSergeantNasty-turned-teacher, Mr. Buzzcut.
* The Gromble from ''[[AaahhRealMonsters AAAHH!!! Real Monsters]]'', who at one point [[BiologicalMashUp forced two students into the same body]] as a punishment for their bickering. One episode hints that his mistreatment is him projecting his pain from the overly tight high-heeled shoes permanently wedged on his feet.
*** If this is referring to the same episode that this troper is thinking of, then it's stated outright that the Gromble is usually so cranky because his shoes pinch his toes. This troper is also pretty sure that they aren't wedged on, but he likes that particular style, and is too stubborn to wear a bigger size
** Don't forget that he friggin' '''ate''' a student on-screen in the first episode because the student accidentally disrupted his lecture by having to chase after his nose, which was running away on little legs.
* Mr./Ms. Garrison of ''SouthPark'' sometimes slips into this trope, openly mocking his students if they get some question wrong. The rest of the time he's just plain incompetent, or perhaps this week he's trying to get the school to fire him so he can sue them, not caring about the mental damage he might inflict on the children in the process.
** This goes even further in the episode where Mr. Garrison hires a masochistic leatherman named Mr. Slave as the teacher's assistant, thus becoming a literal Sadist Teacher.
* Mr. Lancer from ''DannyPhantom'' both uses this trope straight and subverts it. He had the terrible tendency to pick on the unpopular main character Danny by choosing the popular kids over him, harshly criticizing his schoolwork, and doling out punishments, yet a few episodes have shown he does care for all his students, even Danny.
* Subversion in Mr. Ratburn of ''{{Arthur}}'': Ratburn is feared as the strictest and toughest teacher in the school, so his reputation lives up to the trope. However, he is an excellent teacher in spite of, or indeed because of his strictness, and several episodes feature him outside of school in order to humanize him.
** One episode revealed he had an even worse teacher, who was also very competent for the same reasons, when he was in school (he was taught Latin in 3rd grade!).
** He may be a sadist, but when a [[MisplacedKindergartenTeacher Misplaced Kindergarten Substitute Teacher]] took his place one day, everyone wanted Mr. Ratburn back by the day's end.
* A couple of the teachers in ''{{Daria}}'': Ms. Barch hates all her male students, and gives them terrible grades. The unfairness of this is only slightly mitigated by the fact that often they deserve them. Mr. Demartino likes to see ''all'' his students suffer, but in his case it's because he feels it's payback for the pain they put him through with their stupidity. However he greatly fears Ms. Barch (she beat him up in one episode).
* Vice Principal Chakal of ''{{El Tigre}}'' fits this trope. He has it in for Manny and Frida, and enjoys setting harsh punishments for them. However, said students are often troublemaking kids, so this troper can't really blame him.
* Mr. Agar from ''CarlSquared'' definitely has it in for Carl. Mind you, given Carl is the ultimate slacker and he had to deal with angry goth Chloe a few years earlier, a hatred of the Crashman bloodline might not be entirely unjustified.
* Eugenia P. Kisskillya from ''{{Detention}}''.
* In the animated ''{{Peanuts}}'' New Year's special, Charlie Brown's elementary school teacher decides to give the kid ''WarAndPeace'' as a reading assignment. '''''War And Peace.''''' To a ''normal elementary school student.''
* ''TheSimpsons''' Edna Krabappel seems to alternate between being one of these and, more sympathetically, an unfairly put-upon foil to Bart.
** Of course, that's nothing compared to Bart's kindergarten teacher, who is, for all intents and purposes, a CompleteMonster.
* The ''TeenTitans'' episode "Mad Mod" took this to extremes, in which Mad Mod traps the heroes in a school that's constantly trying to kill or brainwash them.
