L'Italiana in Algeri (The Italian girl in Algiers) is an operatic dramma giocoso in two acts by Gioachino Rossini (music) and Angelo Anelli (libretto)

The plot revolves around Isabella, a beautiful Italian girl who expertly juggles her admirers. Even when shipwrecked in Algiers, she never loses her confidence in her own abilities and manages to turn the head of Mustafą, the Bey of Algiers. Using his infatuation to her advantage, the smart Italian girl tricks him into making a fool of himself: in order to be worthy of the entirely fictitious title of Pappataci, he must eat, drink and be silent no matter what happens around him, allowing her to sneak away with all the freed Italian slaves right under his nose.

!!''L'Italiana in Algeri'' provides examples of the following tropes:
* ArrangedMarriage: by Mustafą between Lindoro and Elvira, so he can get rid of her. Privately, Lindoro and Elvira agree not to go through with it.
* BetaCouple: Mustafą and his wife Elvira
* ButtMonkey: Taddeo
* ClingyJealousGirl: according to Mustafą, Elvira is this.
* ContrivedCoincidence: Looking for Lindoro, Isabella just happens to be shipwrecked where he's held prisoner at the right time to start the whole plot.
* CrowdSong: played straight in both acts and at the beginning of almost every scene. Subverted by act II, scene II, which opens with a recitativo
* DidNotGetTheGirl: Taddeo, the comic relief.
* DrowningMySorrows: Taddeo says he'd rather do this than hold the candle to Isabella and Lindoro
* GuileHero: Isabella
* HappyEnding
* IAmSong: ''Gią so per pratica''
* ImpaledWithExtremePrejudice: Taddeo is repeatedly threatened with this. It's PlayedForLaughs.
* IncrediblyLamePun: ''Pappataci' does contain the words "eat" and "hush", but in reality it's the Italian word for "sandfly".
* IWillFindYou: Isabella and Lindoro during Act I.
* LetsDuet
* LoveDodecahedron: Elvira loves Mustafą, who is infatuated with Isabella, who is also courted by Taddeo but loves only Lindoro.
* LoveTriangle: one is averted. Elvira has been promised as a wife to Lindoro, but she only loves Mustafą and he is faithful to Isabella
* MadeASlave: Lindoro sometime before the beginning of the opera.
* MassiveMultiplayerEnsembleNumber: there are three, ''all'' expressing confusion:
** ''Confusi e stupidi''
** ''Va sossopra il mio cervello'' at the end of act I
** ''Sento un fremito, un foco, un dispetto'' in the middle of act II
* MayDecemberRomance: what Taddeo is hoping for.
* MisogynySong: played straight with Mustafą's ''Delle donne l'arroganza'' (Women's arrogance), inverted with Haly's ''Le femmine d'Italia'' (Women of Italy)
* {{Nepotism}}: Mustafą makes Taddeo his Kaimakan (Liutenant) to please Isabella and have "Uncle" Taddeo help him woo her. Taddeo is not pleased.
* NotWhatItLooksLike: Lindoro has to do some fast talking about his supposed engagement to Elvira. Luckily for him, Isabella believes him.
* OfficialCouple: Lindoro and Isabella
* OhCrap: Lindoro's reaction when Isabella is told he's to marry Elvira. Briefly during the Pappataci ceremony as well, when Mustafą is angered by Isabella and Lindoro's flirting.
* OpeningChorus:
** ''Serenate il mesto ciglio'' (Dry your sad eyes) for act I
** ''Uno stupido, uno stolto'' (A fool, an idiot) for act II
* {{Pirate}}: Haly
* PlayingTheVictimCard: to be fair, Isabella is a victim of cirumstances. However, in her previous aria she cheerfully explained how she's not afraid of men and is confident she can manipulate them to her advantage.
* RelativelyFlimsyExcuse: Taddeo and Isabella claim to be uncle and niece so he won't have to do hard work and she won't be alone among enemies.
* SpicyLatina: the reason why Mustafą wants an Italian girl. It turns out Isabella is too spicy for him.
* TwoFacedAside: Isabella in ''Per lui che adoro'', Isabella and Lindoro in ''Maledetto quel balordo''. The arias of the Pappataci ceremony are ''built'' on this.
* ThePowerOfLove: In ''Pensa alla patria'', Isabella claims that's what makes her brave enough to try and trick the Bey.
* TheStoolPigeon: Taddeo tries to tell Mustafą that he's being tricked when he realizes one of the Italian slaves is Lindoro, Isabella's true love. Unfortunately for him, Mustafą assumes it's just part of the test for the title of Pappataci and ignores him.
* ZanyScheme: the escape plan
