'''''Oklahoma!''''' is a 1943 [[TheMusical musical]], possibly the most influential musical in the genre. It was based on the play ''Green Grow the Lilacs'' and adapted by {{Rodgers and Hammerstein}}. Set in 1906, it tells the story of a young cowboy named Curly, and a farm girl, Laurey. They're obviously in love, but neither of them will admit it. The sinister farmhand, Jud, asks Laurey to a dance. Laurey is afraid of him, but she accepts to spite Curly. The story takes a dark turn as Laurey realizes that Jud is dangerous, and that, if she were to turn him down, he could become violent.

The musical is a radical departure from the mostly fluffy musical comedies that had preceded it. It integrated the book (the spoken dialogue) with the music without attempting to justify it. Its use of dance as adding to the plot and atmosphere was also a change from the showgirls of previous musicals. It was not the first to use such techniques (''ShowBoat'', which also featured lyrics and libretto written by Hammerstein, predated it by nearly 20 years), but its impact is unmistakable.

''Oklahoma!'' was successfully adapted to film in 1955, and has been [[{{revival}} revived]] numerous times on Broadway and in London.

!!This play contains examples of:

* AnnoyingLaugh: Gertie, full-stop.
* AntiVillain: As creepy as he is, it's hard not to feel at least a ''little'' sorry for Jud, with the way he's ostracized by the town and seems to be completely starved for affection. Oh, and did we mention the fact that the hero tries to encourage Jud to ''kill himself before he had even done anything wrong?''
** Of course, then the VillainSong "Lonely Room" happens and Jud starts to enter actual villainous territory.
** [[spoiler: Some productions imply that Jud [[KickTheDog started a fire that killed an entire family]] before the play even started. Why? Because the daughter in the family rejected him. This implication happens just before Curly started trying to convince Jud to kill himself.]]
* [[CaliforniaDoubling Arizona Doubling]]: Nogales, Arizona stands in for Oklahoma in the 1955 film.
* [[BadassGrandma Badass Aunt]]: Aunt Eller. At one point, she brandishes a ''gun'' at everyone, in order to make sure everyone gets along.
* BetaCouple: Will and Ado Annie
* BookEnds: The play and movie begin with Curly singing, "Oh What a Beautiful Mornin'" before asking Laurey out to the dance, and end with everyone singing the song while celebrating Curley's and Laurey's marriage and Oklahoma's becoming a state.
* {{Bowdlerise}}: In the play, "Kansas City" had a part with Will singing about how one of the burlesque girls he saw undressed herself to prove that she had a shapely figure, as opposed to a padded outfit. In the movie, Will sings about how when she danced, her body moved naturally.
* TheBrainlessBeauty: Ado Annie
* CarSong: "The Surrey with the Fringe on Top"
* TheCasanova: Ali Hakim.
* CoolOldLady: Aunt Eller.
* CutSong: "Boys and Girls Like You and Me." It later turned up in {{Screen To Stage Adaptation}}s of ''Film/StateFair'' and ''{{Film/Cinderella}}''.
* DreamBallet: The paradigmatic example of the form. Possible TropeCodifier?
* DrivenToSuicide: Curly attempts to do this to Jud in "Pore Jud is Daid".
* TheElevenOClockNumber: "Oklahoma!"
* EthicalSlut: Ado Annie is equal-opportunity in terms of loving the man she's with.
* EvilSoundsDeep: Jud Fry is almost always cast as a bass, although the 1979 revival saw Martin Vidnovic play Jud, and "Lonely Room" was transposed up a third (still keeping it in baritone territory, but with a tessitura higher than a bass's song would have.)
* FarmersDaughter: Ado Annie.
* {{Fate Worse Than Death}}: Ali Hakim's forced marriage to Gertie Cummings. "I thought it would be better to be alive, but now I ain't so sure."
* {{Fauxreigner}}: Ali Hakim can be one depending on the production. Despite the character claiming to be Persian, the part was written for a "Jewish Comic"-type actor, and it is in line with the characterization for Hakim to be an outsider/more worldly than the characters (which a Jew from New York City would be in the setting), but still lying about his background in being American-born. The role finally went to an actual Muslim (although not an Iranian) in a major production when the 2002 Broadway revival gave the part to Aasif Mandvi.
* FelonyMisdemeanor: Laurey is horrified over this, weeps over this, has nightmares over this. Curly would rather see Jud dead than let him go through with this. Curly sells every prized possession he has to stop this from happening. And in the end Jud ''DIES'' over this. The crime? Asking Laurey out on a date, taking her to a party, and bidding on a picnic basket.
** Some stagings of the play add subtext that Jud is going to ''rape'' Laurey if he gets her alone.
* FeudingFamilies: Not families per se, but the farmers and cowboys otherwise fit this trope.
* FinalLoveDuet: "Let People Say We're in Love" - which, unlike most instances of this trope, is actually a reprise (with different lyrics) of the earlier flirty duet "People Will Say We're in Love."
* GoodBadGirl: Ado Annie, who might actually be the UrExample.
* ImmuneToBullets: Jud, in the DreamBallet.
* IWantSong: "Lonely Room," in a...scary sort of way.
* KangarooCourt: The final sequence is the entire town holding a mock trial to excuse Curly for a murder charge. Regardless of whether or not he should have been guilty, they didn't even bother to ''hide'' that they were going to happily let him go after a few seconds.
* KarmaHoudini: Curly's conversation with Jud during "Pore Jud is Daid." Nothing is done to point out how wrong this is.
* LoveTriangle: Curly, Laurey, and Jud; Will, Annie, and Ali Hakim. Laurey, Curly, and Gertie Cummings, to a lesser extent.
* MadnessMantra: [[spoiler: "Think you're better than me..."]]
* MobileKiosk: Ali Hakim the peddler has one of these.
* TheMusical
* NeverBringAKnifeToAFistFight: A lesson [[spoiler: Jud]] would do well to learn.
* PairTheSpares: Ali Hakim and Gertie. An interesting variation as they were paired by being the spares from two completely separate triangles.
* PleaseIWillDoAnything: Not outright stated but implied in the dream sequence.
* PlotParallel
* ReallyGetsAround: She ''is'' a girl who can't say no, after all.
* SerialKiller: [[spoiler: In all likelyhood, Jud himself. Some productions add more hints of this to keep him from being too sympathetic.]]
* SexDressed
* SharpshooterFallacy: In order to try to impress/threaten Jud, Curly shoots a knothole in a beam on the ceiling and claims it was his target. When Aunt Eller comes in to inspect the shot, he tries to make the same claim and she points out that there are a lot of knotholes up on the ceiling.
* ShotgunWedding: Ali Hakim seems to attract these-- Carnes tries to force him to marry Ado Annie. [[spoiler: He escapes that one, only to be forced to marry the intolerable Gertie Cummings.]]
* SidekickSong: "Everything's Up to Date in Kansas City", "I Cain't Say No" and others.
* SnakeOilSalesman: Ali Hakim
* StalkerWithACrush: Jud.
* ThreateningMediator: When the number "The Farmer and the Cowman" breaks up into a feud between the two groups, Aunt Eller intervenes and holds the ensemble at gunpoint to finish the number through to the [[AnAesop Aesop]].
* TomboyAndGirlyGirl: Some variations of Laurey and Ado Annie.
* {{Tsundere}}: Laurey.
* UnableToSupportAWife: Will's problem.
* VillainousCrush: Jud for Laurey, though how much one considers Jud to be a villain is up for debate.
* VillainSong: "Lonely Room," and it's a damn good one. This is the moment that it becomes clear that, Curly being kind of a jerk to him aside, Jud is actually quite dangerous and Laurey may be in trouble.
* WhatTheHellHero: Curly tries to MindScrew Jud into commiting suicide. Why? So that Jud won't be around to ask Laurey out. Even in the productions that add the rapey undertones, this scene happens before Jud does anything worse than express an interest in the same girl as Curly.
