->''Even death has a soft place in his heart for such a paragon, and remedies all mistakes for her just at the right moment. The vicious baronet is sure to be killed in a duel, and the tedious husband dies in his bed requesting his wife, as a particular favour to him, to marry the man she loves best.''
-->-- '''Creator/GeorgeEliot''', ''Literature/SillyNovelsByLadyNovelists''

%% One quote is sufficient. Please place additional entries on the quotes tab.

Alice, Bob, and Charlie are in a LoveTriangle. Alice loves Bob, but also has feelings for Charlie--or maybe she doesn't, but can't or doesn't want to turn him down. Maybe she's even in a relationship with, or married to Charlie, while pining after Bob. However will she resolve this dilemma? Well, fortunately, she doesn't have to--Charlie meets with a convenient illness, accident, or other such fatal situation, freeing Alice up to go after Bob without guilt. If Charlie is aware of Alice's feelings for Bob, he may tell her with his dying breath that she shouldn't mourn him too much, because he [[IWantMyBelovedToBeHappy wants his beloved to be happy]].

Note that not everybody uses "hypotenuse" in the way it appears here, as a triangle only has one hypotenuse, but two other sides (unless it is equilateral), so it would be logical to call Alice the hypotenuse in the above example. See for instance Music/TomLehrer's "[[Music/SongsByTomLehrer Lobachevsky]]", which mentions Metro-Goldwyn-Moskva's production of ''The Eternal Triangle'', "starring Ingrid Bergman as the hypotenuse."

This trope is where ThePlotReaper meets CleaningUpRomanticLooseEnds. If Charlie's death is not so accidental, it's MurderTheHypotenuse or TheUriahGambit, depending on whether it's done directly or set up indirectly. See ComfortingTheWidow. Compare to ShipSinking.

May still be a BittersweetEnding and even lead to DeadGuyJunior.

'''Spoilers may be within.'''


[[folder: Anime & Manga]]
* In LightNovel/{{No 6}} this happens to [[spoiler: Safu]]. Though it's really more of a case of [[spoiler:merging her with a goddess-like entity, thus destroying a huge chunk of her personality, THEN blowing up the building she's in.]]
* In ''Manga/InuYasha'', the Inuyasha - Kikyou - Kagome triangle is finally broken when Naraku engineers Kikyou's death for good, and she ends up perishing peacefully in Inuyasha's arms. [[TearJerker Snifffff]]...
* Discussed in ''Manga/MahouSenseiNegima''. Haruna references how common this happens in Japanese literature when it's revealed that Yue likes Negi in the same way that Nodoka does. The fact that both Yue and Nodoka are standing ''right behind her'' as she does this didn't help the situation at all.
* ''Literature/FromTheNewWorld'':
** It happens the ones involved in the [[spoiler: Saki/Shun/Satoru]] LoveTriangle. It has the twist that the hypotenuse who dies is the member of the LoveTriangle, that ''the other two are interested in'', aka [[spoiler: Shun]].
** Saki's girlfriend, Maria, is forced to run off with her ''other'' potential LoveInterest Mamoru, [[spoiler: leading to both their deaths]].
* In ''Manga/LoveHina'', described in volume 9 of the manga, Haruka, Seta and Sarah's mother were a LoveTriangle. Seta had promised to choose by the time he turned 30, but Sarah's mother died; Haruka refused to accept victory by default, and rejected Seta for years afterwards. [[spoiler:She got over it eventually and they got married.]]
* This is what breaks up the SiblingTriangle between twins Tatsuya and Kazuya and their neighbor Minami in the manga ''Manga/{{Touch}}''. Right before Kazuya was going to ask Minami's dad for his blessing, too... ouch.
* In ''Anime/YuGiOh'', Anzu has a TwoPersonLoveTriangle between Yugi and Yami. [[spoiler:At the end of the series, Yami goes to his final rest, having been a pharaoh who was dead for 3,000 years]].
* ''Manga/HighschoolOfTheDead'': This actually makes things worse for the hero since Rei's now focused on Takashi, but way too often she ends up comparing him to her dead boyfriend Hisashi, or berating him in a way that makes Takashi think she is. She eventually gets over it and admits that she'd dated Hisashi more because it hurt too much to be with him, but now she's all his.
* ''Manga/PsychicAcademy'': The love triangle between Ai, Orina, and Mew ends with [[spoiler: Mew]]'s death. In a subversion of this trope, Ai [[spoiler: decides to spend the rest of his life being true to Mew's memory]].
* ''Anime/MacrossFrontier'' [[SubvertedTrope subverts this]]. Near the end [[spoiler: Sheryl, close to death from her illness pleads Alto to save Ranka, so the two can be together after she dies (emphasized more in the novels, but still present in the series). Then [[LaserGuidedKarma Ranka uses her powers to ''heal'' her CoolBigSis Sheryl]], so the threesome persists, and remains unresolved in the show itself]].
** The movies [[spoiler: ''seem to'' [[InvertedTrope invert this]]. The "hypotenuse" is the only one left standing, while her victorious rival is in a coma, and their object of attraction is missing. However, WordOfGod confirms that they all survive, and implies that the latter two eventually get back together again after the ending]].
* ''Anime/NeonGenesisEvangelion'': The main love triangle between Shinji, Asuka and Rei ceases to exist when [[spoiler: Rei]] pulls a HeroicSacrifice to save Shinji, shortly after arriving at the realization that she "wants to be one with him". As a sort-of deconstruction, [[spoiler: Asuka]] ends up doubting the sincerity of Shinji's feelings, accusing him of comming to her because she's basically the only one left, since [[spoiler: everyone else (including [[CameBackWrong the clone replacing the Rei everyone used to know]]) either scares Shinji or has kicked the bucket]] at this point.
* Many ''Manga/{{Bleach}}'' [=HitsugayaxMatsumoto=] fans see [[spoiler: Gin's death]] as this. [[spoiler: Even when Hitsugaya and Matsumoto ''don't'' end together either.]]
* More than one ''Manga/DetectiveConan'' case has a person killed for being one of the corners of a LoveTriangle or getting in between a potential couple. Much more common if there's an ArrangedMarriage (like [[spoiler: a DrJerk killing his ex-girlfriend so she won't stand in between him and the daughter of his boss whom he's marrying for the prestige]] or {{blackmail}} (like [[spoiler: a policeman shooting his ex girlfriend dead when she attempts to go the HoneyTrap way right as he's actually about to move on with another woman]]) involved.
* ''Anime/AnoHanaTheFlowerWeSawThatDay'' ''[[DeconstructedTrope smashes this to pieces]]''. Back when they were children, [[LoveDodecahedron Anaru liked Jintan and Tsuruko liked Yukiatsu, but both boys liked Menma]] and the girls, despite caring for Menma, [[AlwaysSomeoneBetter felt that they couldn't compete with her]]. Menma's untimely death only made things worse for all of them (and their uninvolved friend Poppo), since such a tragedy [[BreakTheCutie tore the group apart]] and showed that, [[RealityEnsues in reality]], the demise of "the person who gets in between" does NOT equal to the others getting together: the guys got so broken (and Jintan already had his own issues) that [[TheLostLenore no girl in their eyes could match the very high standard that Menma had left]], with Jintan becoming a {{hikkikomori}} and Yukiatsu both considering Anaru as a prospect "back-up girlfriend" (and neither she nor Tsuruko, understandably, are happy with that) [[spoiler: and wearing dresses similar to those Menma used to wear.]]

[[folder: Comic Books ]]
* In ''ComicBook/XMen'', Cyclops making it out with Emma Frost -- almost literally on his dead wife's grave. In this case, the dead wife made them do it with her psychic powers, or rather, the future resurrected her did it, but still perplexing, since [[FridgeLogic there were plenty of other ways she could have made Scott stay]] that were a lot less tacky.
** And later works and materials tried to present it as Emma being there for Scott after Jean died, which is contradicted by the above moment, since he supposedly lost the feelings he needed comforting over.
* [[spoiler:David]] of ''ComicBook/StrangersInParadise''.
* In ''ComicBook/WhateverHappenedToTheManOfTomorrow'', [[spoiler: Superman doesn't want to hurt Lana by officially making a RelationshipUpgrade with Lois, and has decided to never make his feelings known, but Lightning Lord frying Lana in the battle later on conveniently removes the problem, allowing for Superman's HappilyEverAfter ending]].
* The background of ''ComicBook/{{Revival}}'' has Aaron having an affair with Em. Then Em is murdered. Then the Revival hits and she gets better. The relationship never recovers for coincidental reasons.

* Death By UnrequitedLove in ''Film/PiratesOfTheCaribbeanAtWorldsEnd''.
* [[spoiler:Dizzy]] in the ''Film/StarshipTroopers'' movie. Also, [[spoiler: the male fleet pilot who was trying to hook up with Carmen the whole time]]
* Very, very common in war films (all countries, all periods) generally, to the extent that a PairTheSpares solution is the exception to the rule.
* As one such example, ''Film/PearlHarbor''. [[spoiler: Danny dies, letting Rafe get Evelyn...as well as letting them raise [[DeadGuyJunior Danny and Evelyn's chid.]]]]
* In ''Film/TheSearchers'', Martin Pawley finds himself in an AccidentalMarriage to a Comanche woman, nicknamed Look. Naturally, this gets in the way of his relationship with Laurie Jorgenson. When Martin tries to press Look for information about the killer he's tracking, she panics and runs away. Martin later finds her dead-- killed by the US Army in an attack on a Comanche camp.
* A tragic example in ''Film/CrouchingTigerHiddenDragon'', where Shu Lien's fiancee was killed in battle and also happened to be Mu Bai's best friend and sworn brother. For years, the two of them refused to pursue a relationship with each other, to honour the memory of their friend/fiancee.
* ''Film/FirstKnight'' has it with King Arthur's death, leaving Guinevere free to hook up with Lancelot.
* [[spoiler: Gordon]] in ''Film/TwoThousandTwelve''.
* [[spoiler: Tsu'tey]] in ''Film/{{Avatar}}''. Even though Neytiri only ended up having feelings for Jake, she was technically supposed to have been betrothed to him from the beginning, so to free her from any possible obligation to or conflict with him, the triangle was predictably resolved by redeeming his character and subsequently killing him off.
* Cyclops' death in ''Film/XMenTheLastStand'' can be seen as this crossed with [[DisposableFiancee Disposable Fiancé]].
* ''Film/ForbiddenPlanet''. Lieutenant Jerry Farman and Commander Adams are in a romantic competition over Altaira. Jerry is killed by the Creature from the Id when it attacks the United Planets ship and Adams and Altaira end up together.
* ''Film/GoneWithTheWind'': Scarlett has had a crush on Ashley for years, of which he once reciprocated to but then turned her away after he married Melanie. Her crush made her ungrateful for her own doting Rhett. Eventually Melanie dies and her last words seem to be giving Scarlett permission to marry Ashley. By then Rhett has had enough and leaves so she can have Ashley, but she no longer wants him to go. No word after if she marries Ashley.
* In ''Film/{{Oblivion 2013}}'' [[spoiler: Victoria is killed less than a day after Julia comes back into the picture. Bonus points comes from it being her own fault, as she inadvertently sics the Drone on herself as well as Jack.]]
* In ''Film/{{Underworld 1927}}'', Rolls Royce is InLoveWithTheGangstersGirl. In the end, the gangster dies which clears the way for the lovers to resolve their {{UST}} and be happy ever after.
* In ''Film/CatPeople'', the dilemma of the LoveTriangle is being resolved be the death of the heroine.
* In ''Film/{{Unconscious}}'', León's climactic [[FallingChandelierOfDoom death by chandelier]] removes the final obstacle to Alma and Salvador getting together.
* In ''Film/{{Limelight}}'', Creator/CharlieChaplin's character dies in the end, freeing Terry to pursue a more suitable relationship with Neville.
* In ''Film/JurassicParkIII'', the divorced Paul and Amanda Kirby's [[RelationshipSalvagingDisaster reconciliation over rescuing their son Eric]] would have been complicated by Amanda's new boyfriend Ben -- except that he was on the island with Eric, and they find his skeleton hanging from a ParachuteInATree soon after they arrive.
* In [[http://www.salmineo.com/newstand/inter_hadleigh.html a 1972 interview]], when discussing ''Film/RebelWithoutACause'', Sal Mineo observed that his character Plato's death is this trope as well as BuryYourGays, although given the film's era, it's only [[HoYay subtext.]]
---> "... so it's like he [Creator/JamesDean's character Jim] had the hots for Natalie [Wood] and me. Ergo, I had to be bumped off, out of the way."

* ''Discworld/TheFifthElephant'': It happens to [[spoiler:the wolf Gavin, who dies heroically]]. Implied that narrativium was working heavily in favour of the suitor that survived.
** [[AlternativeCharacterInterpretation Another interpretation]] is that [[spoiler: Carrot was deliberately taking advantage of narrativium, and made sure it was Gavin that made the HeroicSacrifice. Whether this was done [[ManipulativeBastard consciously]] or [[TheoryOfNarrativeCausality unconsciously]] is impossible to tell through Carrot's constant ObfuscatingStupidity.]]
* Mandorallen, The Baroness of Vo Ebor and The Baron of Vo Ebor in David Eddings' ''Literature/{{Belgariad}}''. In the fifth book, the Baron is seriously wounded. In one of the first books of the second pentology, the ''Malloreon'', the Baron dies as a result of his injuries, but Mandorallen and the Baroness don't get together until a new hypotenuse shows up - a crony of the Baron's heir. Finally sick of the moping, and the incipient civil war looming between Mandorallen's family and the Baron's, Belgarion storms in and orders Mandorallen and the Baroness to marry and get it over with, paying off the Baron's heir just to make sure everything ''stays'' settled.
* Patricia Kennealy's ''The Silver Branch'', first book of the Keltiad: The protagonist, Aeron marries Roderick because her parents wish her to. Roderick and her parents die in the same well, murder. She then marries Gwydion, which was what she had wanted but her parents thought a pair of magic-wielding royals to be too scary.
* In the novel ''Mary of Marion Isle'' by Creator/HRiderHaggard, the wicked accidental wife accidentally drowns allowing the hero to marry to marry the heroine who is his soul mate.
* Happens in ''Rose in Bloom'' to solve Rose's [[KissingCousins "which one of my cousins do I marry?"]] dilemma, when the TroubledButCute one takes himself out via horseriding accident.
* In ''Literature/TheNightAngelTrilogy'', the protagonist's first love has to make a HeroicSacrifice, and before doing so, [[IWantMyBelovedToBeHappy wishes him happiness]] with the other contender.
* ''Literature/HarryPotter'':
** {{Deconstructed}} in books four and five. In ''Literature/HarryPotterAndTheGobletOfFire'', Harry is in a love triangle with Cedric Diggory and Cho Chang. At the end of the book, Cedric dies, leaving Cho free. In [[Literature/HarryPotterAndTheOrderOfThePhoenix the next book]], Harry and Cho do hook up, but it's portrayed almost as a SexForSolace (but without actual sex) kind of relationship brought on by their mutual grieving. Ultimately, Harry's attempts to repress his SurvivorsGuilt despite Cho's need to talk about Cedric leads them to break up (along with Cho's [[ImaginaryLoveTriangle confusion]] about [[LikeBrotherAndSister the nature of Harry and Hermione's relationship]]). Ultimately they wind up married to different people.
** ''Literature/HarryPotterAndTheDeathlyHallows'' also [[SubvertedTrope subverts this]] with the reveal that Snape was hoping for this in regards to James, who was HappilyMarried with Lily. He had begged Voldemort to spare Lily, but when the time arose Voldemort killed her anyway. This ended with James and Lily being TogetherInDeath while Snape was alone once more.
*** This also means that Snape couldn't have cared less that Lily's son Harry was the target of the entire assassination attempt, maybe even seeing the infant as just another part of the hypotenuse. That's just ''cold''. Dumbledore is ''infuriated'' at this.
* Semi-averted in ''Theatre/CyranoDeBergerac''. After Christian dies, Cyrano has the opportunity to reveal he wrote the letters and finally receive Roxane's love, but he withholds the information so that his beloved Roxane's memory of Christian won't be tarnished.
* In Creator/LoisMcMasterBujold's ''Literature/{{Komarr}}'', Imperial Auditor Miles Vorkosigan finds himself falling in love with Ekaterin Vorsoisson, the wife of an administrator peripherally involved with an apparent terraforming accident (and the feeling is, unbeknownst to him, mutual). Tien Vorsoisson turned out to be involved in an embezzlement scam, Ekaterine decided to leave him over it, and ''then'' Tien ended up accidentally killed by the conspirators when he tried to sell them out to Vorkosigan. Too bad things got classified enough to create a whole new set of barriers in any courtship.
* This is how the love triangle in ''Literature/TheCastleOfOtranto'' (the first GothicNovel) was resolved, although it's a bit of an unusual variation. While the two surviving sides of the triangle do marry, they're both deeply distraught over the death (as the two love rivals were quite close friends), and it's said that part of the reason they get together is that they know that no one else will fully understand their grief.
* In Juliet Marillier's ''Literature/HeirToSevenwaters'', the heroine starts out courting Aidan before realizing she has feelings for Cathal. This dilemma is resolved when [[spoiler:the villain randomly kills Aidan ... [[ForTheEvulz because he can]]]], preventing Clodagh from having to make a hard decision.
* ''Literature/{{Lolita}}''. Charlotte wants Humbert; Humbert wants Lolita. Charlotte dies in a freak accident.
* In Samuel Shellabarger's novel [[http://en.wikipedia.org/wiki/Prince_of_Foxes Prince of Foxes]], the adventurer Andrea Orsini and the lady Camilla Varano discover an increasing attraction to each other which both resist out of respect for her CoolOldGuy husband Lord Varano. Varano dies heroically during the climactic siege of Città Del Monte, pushing Andrea and Camilla into each others' arms with his dying words.
* ''Literature/{{Middlemarch}}'': Mr Casaubon tries hard to avert this in Creator/GeorgeEliot's novel, by forbidding Dorothea from marrying Ladislaw in a codicil to his will, on pain of having her inheritance stripped. [[spoiler: Ultimately the plan fails and she marries Ladislaw anyway.]]
* ''[[Literature/{{Indigo}} Troika]]''. Poor, doomed [[spoiler:Veness]].
* The ''Literature/HIVESeries'': ''Zero Hour'' resolves the [[spoiler: Otto/Laura/Lucy]] love triangle by having [[spoiler: Lucy heroically TakingTheBullet for Otto soon after their relationship begins to develop]]. Predictably, in the next book, [[spoiler: Otto and Laura's relationship starts to develop]], but, less predictably, it turns out [[spoiler: Laura has been threatened into turning traitor]], delaying their relationship further.
* ''Literature/WarriorCats'': Brambleclaw and Ashfur both love Squirrelflight. Subverted in that [[spoiler:the hypotenuse dies long after the relationship issue ends]].
* In ''[[Literature/SweetValleyHigh Sweet Valley University]]'', Elizabeth breaks up with her long term boyfriend Todd and he begins dating another girl, Gin-Yung. Gin-Yung conveniently contracts a brain tumour and dies, using her last words to tell Todd to get back together with Elizabeth.
* S.L. Viehl's ''Literature/{{Stardoc}}''. Poor, doomed [[spoiler:[[BlueSpaceBabe Kao Torin]]]].
* Robin Hobb's ''Literature/{{Realm of the Elderlings}}'' series, [[spoiler:Burrich is badly injured in a fight against a stone dragon.]] Despite the fact that there were three separate ways to save his life, only one is attempted and deemed too difficult. [[spoiler: He eventually dies, his body thrown into the sea, and Fitz is now able to move in on Burrich's widow Molly, his childhood sweetheart.]]
* In the final book of the SequelSeries of ''Literature/The39Clues'', [[spoiler: Evan, Amy's boyfriend, is killed off for the sole purpose of letting Amy and Jake be together--although she was already cheating on Evan with Jake, anyway. (The entire book was out-of-character for Amy.)]] The fandom was enraged.
* In the ''Literature/{{Xanth}}'' book ''Isle of View'', the characters themselves invoke this--Prince Dolph is engaged to both Nada and Electra, and for various complicated reasons cannot just pick one. With the deadline coming up, Electra and Nada (who get on quite well) quietly start taking turns anytime anything dangerous needs to be done, just in case fate should resolve the problem that way.
* Happens to Literature/HoratioHornblower three times over the course of the novels. Hornblower is initially married to Maria, and his LoveInterest, the Lady Barbara Wellesy, goes on to marry Admiral Percy Leighton after being spurned by Hornblower. Hownblower is naturally placed under Leighton's command, and is taken prisoner after his ship is disabled in combat. He escapes captivity, and meets Marie, a French widow who helps shelter him, and they start an affair. Hornblower returns to England to learn that Leighton died in battle, and Maria died in childbirth, putting both Hornblower and Barbara in position to marry. A few books later, Marie turns up again, and is killed [[LaResistance fighting Napoleon's troops]] after his return to France.
** Four ways, [[HeterosexualLifePartners if you count]] [[spoiler: Lieutenant Bush, [[AnyoneCanDie who dies in the same book as Marie.]]]]
* Creator/EdgarRiceBurroughs was fond of the plot where the heroine is engaged to another, and the hero nobly relinquishes her because he knows she's too honorable to break her word, and then they suffer for a bit before the inconvenient fiancé has a convenient death (sometimes being handed the JerkassBall first to make sure the reader doesn't feel sorry for him).
** ''Literature/TarzanOfTheApes'' ends with Jane, uncertain of her emotions, accepting a proposal from the RomanticFalseLead, and Tarzan, accepting that she's honor bound, choosing not to make an issue of it and going off alone. In the sequel, ''The Return of Tarzan'', Jane and her fiancé go on a cruise and are shipwrecked, coincidentally very near Tarzan's latest adventure. The fiancé, who by this time has turned out to be a selfish jerk, dies, and Jane and Tarzan are reunited.
** In ''Literature/TheMadKing'', Barney Custer and Princess Emma of Lutha fall in love while Barney is performing an EmergencyImpersonation of Lutha's king, to whom Emma is betrothed. They're both too noble to act on their feelings when she's bound by her betrothal, so they suffer separately for a few years before King Leopold has a DeathByIrony brought on directly by his jealousy over Emma's love for Barney.
* In the Creator/DanielleSteel novel ''A Perfect Stranger'', a young woman's much older husband finally passes away, leaving her free to be with the lawyer she's fallen in love with.

[[folder: Live Action TV]]
* In ''Series/AgentsOfShield'', Simmons ends up entering a relationship with a stranded astronaut named Will in the interregnum between seasons 2 and 3, much to the discomfort of Fitz, who had asked her out moments before she got sucked into a portal that transported her to the world Will was living on, and only finds out about this after risking his life to bring Simmons back to Earth. After a while Fitz comes to terms with this and decides to pull IWantMyBelovedToBeHappy, but then the winter finale reveals that Will was killed by Hive shortly after Simmons was rescued.
* ''Series/BattlestarGalactica2003'':
** Dualla has some UST with Lee (which is mostly built up in deleted scenes), but is in a relationship with Billy. He asks her to marry him and she refuses because of her feelings for Lee, then Billy is conveniently killed off by the villain of the week.
** Notably an AvertedTrope for the most part with any love-triangle involving Lee and Starbuck (and there's a few). His brother's death in the backstory kinda counts as shown in one of ''the last episodes'' when a flashback shows Lee and Kara were interested in each other from the moment Zack introduced his fiance to his brother.
* In ''Series/{{Arrow}}'', there is a LoveTriangle between Oliver, Laurel (his ex-girlfriend), and Tommy (his best friend who dated Laurel for a while). At the end of Season 1, [[spoiler: Tommy is killed coming to Laurel's rescue while her office building collapses.]]
* ''Series/ChoujinSentaiJetman'': Played with: after a series-long love triangle between Ryu, Kaori and Gai, the WhereAreTheyNowEpilogue shows that [[spoiler:Gai]] is fatally knifed by a bandit on his way to [[spoiler:Ryu]] and Kaori's wedding. However, by this time he had come to accept them as a couple, and makes it to the wedding to congratulate them before he dies. [[spoiler:Maria/Rie]] would also count as this, since [[spoiler:her]] death gives [[spoiler:Ryu]] the closure he needs to finally begin a relationship with Kaori.
* ''Series/DegrassiHigh'': Has a baroque (and rather creepy) example. In the first season, Caitlin dumps Joey because he's rather immature, and because the new kid Claude seems so much more her type. But Claude turns out to be an ass and she dumps him too. In the second season, Claude is thinking of suicide (due to unrelated problems that Caitlin doesn't know about). Desperate for any hope, he asks Caitlin out again, and she tells him to get lost. When she gets home, she finds Claude has sent her flowers and his suicide note. As she's screaming with rage and guilt, her science teacher orders her to tutor her old ex-boyfriend Joey. He's had a lot of Character Development over the course of this season, and comforts her during the tutoring. Soon, they're back together again.
* ''Series/DoctorWho'': In [[Recap/DoctorWhoS27E12BadWolf "Bad Wolf"]], the Doctor invites a sweet young woman by the name of Lynda aboard the TARDIS. His regular companion, Rose, who's been in love with him for most of the series, isn't at all impressed by this development. Fortunately for Rose's peace of mind, Lynda doesn't make it to the end of [[Recap/DoctorWhoS27E13ThePartingOfTheWays the following episode]].
** Series 8 establishes Danny Pink as a love interest for Clara Oswald after the Twelfth Doctor, having regenerated into an older form, basically pushes her away and puts and end to the romance that had been brewing with the Eleventh (acknowledging that the Eleventh thought of himself as her boyfriend). This evolves into a somewhat bizarre LoveTriangle scenario as the season progresses and it becomes clear that the Doctor and Clara's feelings for each other remain in place - yet Clara is simultaneously also in love with Danny. Ultimately, it's not the Doctor who gets killed off, it's Danny. Followed by an IWantMyBelovedToBeHappy moment in which a dream construct of Danny (created by Clara's mind - long story - but implied to possibly be the spirit of the real Danny) tells Clara to move on with her life; this almost immediately leads to an implied form of RelationshipUpgrade between the Doctor and Clara in Series 9.
* ''Series/{{Dollhouse}}'': Mellie loves Paul. Mellie leaves. Paul loves Echo. Echo loves Paul. Mellie returns - Paul loves Mellie too. Mellie dies. Paul and Echo can be together! [[spoiler: Well, until ''he'' dies.]]
* ''Series/DowntonAbbey'':
** Has [[spoiler:Lavinia]] die suddenly of Spanish Flu at the end of series two to make way for [[spoiler:Matthew/Mary]].
** Earlier in the series, Vera Bates unexpectedly commits suicide, allowing Bates to marry Anna. Not that this actually makes things any easier, since he's [[{{Cliffhanger}} now]] the prime suspect for her "murder".
* ''Series/{{Farscape}}'': [[spoiler:Gillina]] meets this fate at the end of season one -- the penalty for coming between OfficialCouple Aeryn and Crichton. Interestingly, so does [[spoiler:Crichton]]. For the same reason.
* ''Series/TheFlash2014'' has a LoveTriangle between Barry, Eddie, and Iris. Eddie planned to propose to Iris, but he [[spoiler:commits suicide to RetGone his future descendant, the [[BigBad Reverse-Flash]].]] Given that Barry and Iris have always been each other's OneTrueLove, however, it's unclear whether the latter's marriage to Eddie would have lasted anyway.
* ''Series/{{JAG}}'': An unusual example in "Pilot Error", in that it was the object of both parties' affection, Harm's friend and Annie's husband, rather than one of the competitors, who dies.
* ''Series/JaneTheVirgin'' technically ended the Michael/Jane/Rafael triangle halfway through season 2 by having Jane choose and marry Michael, but with Rafael still in the picture, lurking in the background and dropping subtle hints here and there, viewers speculated that it was only a matter of time before the triangle resurfaced again. Eventually it was resolved for good with Michael's death, clearing the path for a possible Jane/Rafael reunion.
* ''Series/HomeAndAway'': Belle was killed off, apparently paving the way for Aden and Nicole.
* ''Series/{{Justified}}'': Boyd Crowder has liked Ava for quite some time but she was married to his brother Bowman. However, Bowman was an AbusiveSpouse and Ava ends up shooting him dead. When he hears what happened, Boyd is quite thrilled that Ava is single once again (he did not really care much for his brother or the way he treated Ava).
* ''Series/{{MADtv}}'': Parodied in one skit, where two lovers are trapped in the middle of open water, along with their beautiful diving instructor. The ''second'' the husband goes with the female diving instructor, Kelly Clarkson, Kelly dies.
* ''Series/{{Neighbours}}'': Killed off [[spoiler:Bridget]] for this reason and this reason alone. Apparently the writers didn't want to ruin the apparently endless opportunities for a good teenage romance plot by a marriage. It was a storyline that many fans hated because the two were always portrayed as [[HappilyMarried happily married and madly in love]].
* ''Series/NoahsArc'': [[spoiler:Dre at the end of season 2, freeing up Wade to be with Noah again]].
* ''Series/OnceUponATime'': In the first half of season 3, Emma struggles between her feelings for [[NewOldFlame her son's father Neal]] and those for [[BelligerentSexualTension Captain Hook.]] [[spoiler: Eventually Neal pulls a HeroicSacrifice and Emma and Hooks end up together by the finale.]]
** [[spoiler:Rumpelstiltskin]] was involved in ''two'' love triangles that ended this way.
*** Even better, [[spoiler: he had a hand in killing both of them]]
* ''Series/{{Revolution}}'': In the [[Recap/RevolutionS1E20TheDarkTower first season finale]], Nora tells Rachel that Miles has feelings for her, despite the fact that Nora and Miles had just hooked up and rekindled an old flame together. Not long after, [[spoiler:it's Nora who]] takes a round to her liver and [[DiedInYourArmsTonight dies in]] [[PietaPlagiarism Miles' arms]].
* ''Series/{{Smallville}}'': {{Temporary Love Interest}}s [[spoiler:Kyla and Alicia]] dies so Clark could go back to being crazy over [[CreatorsPet Lana]].
* ''Tayong Dalawa'' (lit. ''The Two of Us''): Filipino prime time drama, where this is rather overdone. The show's title is ambiguous title. It could either mean the two half-brothers, or one of them and the girl. It gets hyped up in a TonightSomeoneDies preview, [[spoiler: and is nicely (in a narrative sense) subverted when the girl dies. This underscores the point of the series, which is about the two brothers putting aside their differences becoming family.]]
* ''Series/TerraNova'': Josh wants to bring his girlfriend there from the future, even going so far as to make a deal with the Sixers to do so. His pretty female friend Skye decides to help, despite the fact that she obviously likes him. The Sixers manage to get his girlfriend on the next pilgrimage, [[spoiler: but she dies immediately after coming through the time fracture when the Phoenix Group sends through a suicide bomber.]]
* ''Series/AsTheWorldTurns'': The love triangle between Luke, Noah, and Reid. Reid is killed off and Noah decides to move to LA, leaving Luke/Noah with a MaybeEverAfter at best.
* ''Series/HowIMetYourMother'' had this with Robin/Ted/The Mother in the series finale. Robin stopped hanging out with the gang not only because she’s busy with her job but she couldn’t stand Ted and The Mother enjoying themselves and that her ex-husband is there. [[spoiler:In the end, it turns out the Mother died and Ted got the permission from his kids to date Robin again]].
* ''Series/{{Revenge}}'': All of Emily Thorne/Amanda Clarke's love interests except for [[spoiler:Jack Porter]] were KilledOffForReal. [[spoiler:Aiden Mathis was killed by Victoria Grayson right after Emily finally got her revenge and cleared her father's name. Daniel Grayson died protecting Emily, and this was long after the Daniel/Emily ship had been sunk to the bottom of the ocean (though Daniel had redeemed himself before his death). Ben Hunter, a fourth option introduced in Season Four and one who was never really a serious contender, even compared to Daniel, was killed in one of the last episodes by an assassin. That left ChildhoodFriend Jack as Emily's final and true love interest]].

* One issue of ''ComicStrip/TheFarSide'' featured two men and one woman on a desert island. One of the men gets flattened by a meteor, much to the delight of the other.

* Eponine's death in ''Theatre/LesMiserables'' (in the book she was more of a StalkerWithACrush than an actual romantic option, though).

* ''TabletopGame/BattleTech'' the death of Omi Kurita left Victor Steiner-Davion heartbroken, but Isis Marik was able to snap him out of his despair. The two later married and had three children.

* If you happen to be a female in ''[[Franchise/MetalGearSolid Metal Gear]]'' and [[CartwrightCurse Otacon]] loves you, expect to [[StuffedIntoTheFridge die in a cruel, yet beautiful way]]. The tendency for every girl that Otacon falls in love with to die is a big contributor to his HoYay-addled relationship with Snake.
* Happens in ''VideoGame/TalesOfMonkeyIsland'' episode 4, when [[spoiler: Morgan [=LeFlay=] dies]].
* ''VideoGame/FinalFantasyVII'': The LoveTriangle between Cloud, Aeris, and Tifa ends when [[ItWasHisSled Aeris dies]]. Amazingly enough, there's ''still'' ShipToShipCombat between Cloud x Aeris fans and Cloud x Tifa fans, arguing who Cloud loves. Don't forget the Cloud x Seph and Cloud x Zack fans.
* ''VideoGame/MassEffect3'' can do this with love triangles involving love interests from the first two games, usually by killing off the ''VideoGame/MassEffect2'' love interest. [[spoiler:Thane]] automatically dies no matter what, and [[spoiler:Miranda, Jack, and Tali]] can also die, but that's up to the player's actions.
** Can also be done with the ''VideoGame/MassEffect1'' love interest if it's [[spoiler: Ashley or Kaidan]] that was Shepard's love interest in the original. [[spoiler: Just have Shepard be forced to shoot them dead.]]
** Can also apply to [[spoiler: the Virmire mission if the player wants to romance Liara without being confronted by Ashley or Kaidan.]]
* Their relationship is never called love, though otherwise is handled with the subtlety of a gorilla wielding a sledgehammer, but in ''VideoGame/{{Xenoblade}}'', there's Reyn, Sharla, and Gadolt, wherein it initially appears that Reyn is a ReplacementGoldfish to Sharla, but then [[spoiler: it's revealed that humans harvested by the Mechon are made into Face Units. Gadolt was one, and so Sharla's fiance is back from the dead, complicating the nascent romance between Reyn and Sharla the story has been teasing to this point, but almost as quickly as he enters the plot, Gadolt pulls a HeroicSacrifice and is out of the picture again.]]
* In ''VideoGame/AzureStrikerGunvolt'' 2, there was ''some'' form of love triangle between GV, Joule & Quinn, with Joule occasionally intervene in the conversation between GV and Quinn out of jealousy. In the true ending epilogue, [[spoiler: Joule's "passing"]] leaves no obstacle for [[spoiler:Quinn]] to have GV to herself & GV (now wearing civilian clothing) moving on his life with [[spoiler:Quinn]], wishing happiness for [[spoiler:Joule]]. That said, it should be noted that [[spoiler:Gunvolt still seems to treat Quinn [[ObliviousToLove more like a close friend than a romantic interest]].]]
* Throughout the ''[[Franchise/PrinceOfPersia Prince of Persia: Sands of Time]]'' trilogy, the titular hero has two love interests: the Indian princess Farah from the first game and the Empress of Time Kaileena from the second one. He leaves the former after saving her life, and hooks up with the latter in ''Warrior Within'''s canonical ending. However, in ''Two Thrones'', Kaileena is murdered by the BigBad early into the game and the Prince is reunited with Farah, making a case of FirstGirlWins.

* Averted very notably in ''Webcomic/GirlGenius'', where a major plot arc involved the heroine and her love interest curing the other love interest of a fatal disease ([[DeathIsCheap okay, so they did kill him a little bit]], but it was more of a ''rolling'' death, and he has recovered now).
** An earlier hypotenuse, an actor named Lars, did die, but neither of Agatha's primary love interest were ever aware of his existence, much less his removal from the equation.
