->'''Max:''': ''(As Agent 99 tries to kiss him on the cheek while in the middle of CONTROL headquarters)'' 99, no one at Control knows we're dating.\\
'''Chief''': ''(walking past with a piece of cake.)'' [[EverybodyKnewAlready Yes, they do.]]
-->-- ''Film/GetSmart 2008'' Film

Two characters suddenly wind up in a relationship together, and decide, to keep it a secret from everyone. The reason can be perfectly solid, e.g. one of them is the other's boss, but just as often it can be an ill-defined "I'm not ready for them to know" excuse. They remain awkwardly but successfully concealed for several episodes, speaking in {{Unusual Euphemism}}s, constantly leaving to TalkAboutThatThing and generating many a FawltyTowersPlot -- basically put, behaving in such a manner that requires all other characters to juggle the IdiotBall like crazy.

Eventually they will be found out. This is not a variable -- the SecretRelationship is made to be discovered. The only variation is when, how, and whether everyone finds out at once or just one or two people find out at first and have to help keep the secret until everyone else finds out. A common humorous scenario is that [[EverybodyKnewAlready everyone knows, but don't care; or think it's funny watching them scramble to hide.]]

This can also be played for drama. Two people might be good friends, while aware that their parents, or the outside world, wouldn't approve of their friendship. In an attempt to prevent that from being discovered, the friends do everything they can to hide it, but sooner or later, hell will break loose. ''Theatre/RomeoAndJuliet'' may be the most well-known variation of this.

Naturally, a necessary precaution when DatingCatwoman.

''Spoilers ahoy, readers, beware!''

!!Examples:

[[foldercontrol]]

[[folder:Anime & Manga]]
* ''MarmaladeBoy'':
** Meiko and Shinichi aka Nachan because [[TeacherStudentRomance he's her teacher]]. While Yuu finds out early on, the rest of the cast doesn't until they're caught and it becomes a scandal.
** Later, Miki and Yuu get tangled up in one because [[FlirtyStepsiblings they're stepsiblings]] and Miki's mother Rumi warned her not to fall in love with Yuu in the first place. [[spoiler: She was actually joking, and once they tell the parents, they accept it. (It's handled differently in each media, though).]] Also, the ''original'' ending planned (as mentioned in the mangaka's afterword in the last tankoubon) was that [[spoiler: Miki and Yuu ''were'' half-brother and -sister and stopped dating, moving onto college. But the mangaka pussied out.]]
* The premise of ''Anime/PleaseTeacher'', where Mizuho and Kei are married even though [[TeacherStudentRomance she's his teacher]]. She's also [[HumanAliens an alien]], but that's treated as a much less dangerous secret.
* Nanao and Matsumoto from ''JunsuiAdolescence'' keep their relationship secret due to it being a taboo GirlsLove TeacherStudentRomance. Their friend Hanada-sensei figures it out regardless.
* ''Manga/AiYoriAoshi'''s leads- Kaoru Hanabishi and Aoi Sakuraba- have an ArrangedMarriage [[ChildhoodMarriagePromise from way back when]] and are [[PerfectlyArrangedMarriage very much in love]], but Aoi's family, in order to avoid a scandal (the marriage had been called off when Kaoru left the Hanabishis due to [[AbusiveParents the abuse from his grandfather]]), force them to keep it a secret. Since this is a HaremSeries, and several girls with romantic interest in Kaoru come to live with him, HilarityEnsues.
* In ''HanjukuJoshi'', Yae and Chitose keep their relationship secret for a while, since Yae is afraid that their peers will judge them for being SchoolgirlLesbians.
* In ''VisualNovel/SchoolDays'', Makoto and Sekai both decide to date (and sleep with) each other, while Makoto is still in a relationship with Kotonoha, which he also never really breaks off and continues to lead her on. It gets worse from there. [[AxeCrazy Much, much worse]].
* Played with left and right in ''Manga/FruitsBasket''. The Head of the Sohma family (and [[spoiler:God of the Zodiac]]), Akito, is dangerously unstable and particularly susceptible to the GreenEyedMonster when it comes to the members of the Zodiac, so this seems to be the only kind of relationship they can have.
** Subverted with [[StoicWoobie Hatori]] and Kana. While their relationship may not have been intentionally kept a secret to people outside of the Sohma house, Kana and Hatori formally go to Akito to ask for a marriage blessing. Akito treats this knowledge as a secret that was kept from him [[spoiler: or better said her]], and flips out accordingly by smashing a vase into Hatori's head, [[EyeScream effectively blinding him in one eye]] in the process. Kana's witnessing of this and Akito's [[MindRape accusation that this happened because of their relationship]] breaks Kana to the point where Hatori had to [[LaserGuidedAmnesia erase all her memories of their relationship]] to save her from her depression.
*** [[BrattyHalfPint Hiro]] similarly ends up telling Akito about his love for [[{{Kawaiiko}} Kisa]]...''before he even confesses his love to Kisa''. Suffice it to say that he ends up regretting it, and although he eventually gets over it, he doesn't actually confess his love to her for a long time.
** [[CloudCuckooLander Haru]] and [[BrokenBird Rin]] play this trope the most straight, being in a relationship but not telling anyone about it. Naturally, this ends in tragedy when Akito ''does'' find out: [[spoiler:Akito blames Rin for it and promptly [[DestinationDefenestration throws her out a second-story window]], landing her in the hospital]]. The idea is still somewhat deconstructed, though, since it's clear that their choice to keep their relationship a secret is indicative of their [[PoorCommunicationKills poor communication]] in general, which causes still more trouble for them as time goes on.
** Surprisingly averted with [[CampStraight Ayame]] and Mine. They clearly like each other and would [[spoiler:(and do)]] get together in a heartbeat if Aaya wanted to, but knowing that it would only end in heartbreak, he just ''doesn't start a relationship''.
* While most of their friends, and their parents, are well-aware of their relationship, Shuichi and Anna from ''WanderingSon'' have this type of relationship. It mainly has to do with the fact Anna is a model, and that Shuichi is [[{{Transsexual}} transgender]].
* ''RanmaOneHalf'': Played for laughs when [[BelligerentSexualTension Ranma and Akane]] try to pretend they were secret lovers all along. Most people don't buy it though. [[UnluckyChildhoodFriend Ukyo]] is convinced Akane is forcing Ranma to lie and the rest of the school knows the two of them aren't really HappilyMarried because they're not arguing.
* Ohgi and Villetta of ''CodeGeass'' have a relationship that remains hidden throughout most of the series.
* In ''Manga/{{Naruto}}'', Asuma and Kurenai had been seeing each other, although they tried to keep it quiet and denied that they were. [[spoiler: The truth comes out with [[SomeoneToRememberHimBy Kurenai's pregnancy]], however,]] and all the other ninja suspected there was something going on between them anyway.
* Mari and Akko in ''GirlFriends'' keep their relationship from their friends, probably because [[SchoolgirlLesbians they're both girls]] and aren't sure how they would react. However, while Sugi-san had mostly figured it out even before Akko and Mari had (thanks to a rather transparent attempt at IHaveThisFriend by Akko), even in the epilogue set a year after they got together Tamamin still hasn't figured it out.
* [[ViolentlyProtectiveGirlfriend Reina]] of ''YandereKanojo'' would very much like to keep her relationship with [[TheStoic Manabu]] under wraps, to protect her status as a {{delinquent}}. Manabu himself doesn't really mind one way or the other, but it quickly becomes clear that [[EverybodyKnewAlready pretty much everyone knows about it, anyway.]]
[[/folder]]

[[folder:Comic Books]]
* ''Comicbook/{{Empowered}}'' gives us [[VainSorceress Sistah Spooky]] and [[spoiler: [[DisabilitySuperpower Mindf**k]]. Even after their breakup the former is horrified by the idea of anyone knowing she was in a romantic relationship with a ''blonde'' woman.]]
* Lightly parodied/inverted in the last volume of ''ComicBook/ScottPilgrim'' with Stephen Stills and [[spoiler:Joseph. He wasn't particularly trying to hide it; Scott was just too dumb and self-absorbed to realize it.]]
[[/folder]]

[[folder:Fan Works]]
* Several of the ''Series/WizardsOfWaverlyPlace'' stories that feature [[BrotherSisterIncest Justin/Alex]] as the main couple.
* The ''Manga/FullmetalAlchemist'' fan fiction [[http://www.fanfiction.net/s/2974475/1/bBest_b_bKept_b_bSecret_b Best Kept Secret]] uses this trope as its basic premise, exploring how the story might have gone if Roy and Riza were secretly married throughout the entire thing.
* Many ''SoulEater'' fanfics that pair Soul and Maka together have them trying to keep their relationship a secret. Usually it has more to do with Maka's OverprotectiveDad than with their friends.
* The ''Series/{{Sherlock}}'' and ''Literature/HarryPotter'' crossover fanfic ''The Magic of Deduction'' has John and Sherlock fake breaking up to protect John from Moriarty. Slightly different as the two hardly had any contact with each other over the period of time in which they were "broken up"
* [[BetaCouple Tsukasa and Miyuki]] in ''FanFic/StarsAbove''.
* [[spoiler:Hisao and Misha]] in the ''VisualNovel/KatawaShoujo'' fic ''FanFic/FromShizunesPerspective'' [[spoiler:Shizune]] is upset by the fact that they kept it a secret from her.
* Possibly due to ValuesDissonance [[note]]Although it's unclear what Konoha and the Hyuga clan think of relationships between first cousins[[/note]], one [[KissingCousins Neji/Hinata]] fanfic in {{Naruto}} portrayed their relationship as this, even when Hinata had Neji's child.
* Merely the tip of the iceberg in ''FanFic/TheSecondTry''. TheReveal was really something to behold.
* ''VisualNovel/AceAttorney'' fanfic ''FanFic/DirtySympathy'' has Klavier and Apollo keep their relationship under wraps because at first Daryan would have killed Klavier for infidelity, secondly to keep people from looking too closely at their actions and so that officially people don't realize that they know each other.
* Inverted in one story of the ''FanFic/FacingTheFutureSeries'' where Danny and Sam pretend to be ''broken up'' to get a bunch of ghosts trying to separate them to back off. Unfortunately, their friends fall for the ruse too.
* In ''FanFic/{{Shatterheart}}'' [[spoiler: R!]]Syaoran and Kurogane keep their FriendsWithBenefits relationship a secret because [[spoiler: R!]]Syaoran was still in love with Sakura and didn't want her finding out and so they could end it without anyone finding out. When Fai finds out about it due [[InterruptedIntimacy to walking in on them]], things get worse.
* By ''Fanfic/TheWrongReflection'' Eleya and Gaarra have graduated to OfficialCouple status, but they're still keeping the relationship secret because it's against regulations (she being his direct superior officer and all). So far they've only told Eleya's parents and sister, but it's briefly implied in the first chapter that Eleya's NumberTwo, Tess Phohl, knows and isn't saying anything.
[[/folder]]

[[folder:Films]]
* This is the major driving force of ''LawnDogs''. A 10-year-old girl and a widely distrusted 21-year-old lower-class man have a platonic friendship, that is tragically misinterpreted when discovered.
* In ''StarWars'', Anakin marries Padme in secrecy due to the Jedi Code forbidding attachment.
* In the film, ''Film/GoodNightAndGoodLuck'', Joseph and Shirley Wershba have to keep their marriage secret from all their colleagues ([[spoiler: Pretty much all of them know anyway]]) as the rules at the time did not permit a married couple to work together. This is a case of TruthInTelevision as all the events of the film are factual.
* ''Film/AlienCargo'': As it’s against company regulation, Chris and Theta have to keep their relationship secret from their colleagues. They’re delighted that by chance they get to spend their shift out of cryosleep together, but later find out that this has exposed them to a dangerous virus that has infected the ship's living quarters.
* In the film ''ThePainting'', Ramo and Claire are in love, but since he's a Alldunn and she's a Halfie (basically he's part of the elite class while she's part of a poor class), they try to meet in secret. They're apparently really bad at it though, since [[EveryoneKnewAlready everyone knows]], which is soon PlayedForDrama.
[[/folder]]

[[folder:Literature]]
* In the ''[[Literature/TortallUniverse Song of the Lioness]]'' quartet, Alanna and Jon start a relationship in the second novel. However, seeing as she's [[SweetPollyOliver disguised as a boy in order to become a knight,]] and he's the heir to the throne, they keep this under wraps.
* In Literature/TheBible, Abraham kept his marriage with Sarah a secret from two different local rulers (claiming she was his sister) for fear that those rulers would [[MurderTheHypotenuse murder him so they could take her for themselves]]. This makes this OlderThanFeudalism.
* Used a lot [[RuleOfDrama for some reason]] in ''[[Literature/WarriorCats Warriors]]'', as there are four separate Clans and the cats have a bad habit of falling in love with someone from another Clan. As you can imagine, [[StarCrossedLovers these never end well]].
** Not to mention the fact that the medicine cats keep on falling in love even though they're not supposed to.
* Matt and Kate in ''[[Literature/{{Airborn}} Starclimber]]''. Kate's parents want her to marry someone else, and would definitely not approve of her marrying Matt because of his working-class origins.
* Terence and Eileen in ''The Squire's Tales'' series. Terence is the main protagonist of the first two books; Eileen first appears in book 2, and they start a romance but don't make it public because Eileen is a noblewoman and her reputation would be ruined if she were known to be in love with a squire. The next few books focus on other characters, with Terence and Eileen making only cameo appearances. Then in the ninth book, it's revealed that they've been married since shortly after book 2, but have kept it a secret for fifteen years - though at least one other character can tell the moment she sees them together, and is confused when she finds out they don't share a room. [[spoiler: Then at the end of the book, they decide "the hell with it" and have a second wedding in public... and Terence gets knighted, making it a non-issue anyway.]]
* Jaime and Cersei Lannister from ''Literature/ASongOfIceAndFire''. This is problematic because they share a last name [[YourCheatingHeart not due to marriage]], but due to [[{{Twincest}} blood relation]], and the fact that he fathered her children instead of Cersei's actual husband helps kick of a civil war.
* In Creator/JaneAusten's ''Literature/{{Emma}}'', [[spoiler: Frank Churchill and Jane Fairfax]] are into a secret ''engagement'' which they hide extremely well. They feared that his family would not approve.
* ''Literature/SenseAndSensibility'': [[spoiler:Edward Ferrars and Lucy Steele]] got engaged when they were but teenagers, and kept the relationship secret for four years because he would be disinherited had he married her. She's a scheming and calculating girl who really doesn't deserve him or like him, but figured that a genteel man without money is still a catch.
* It's revealed at the very end of ''Literature/NorthangerAbbey'' that [[spoiler:Elinor Tilney]] was in love with "the most charming young man in the world". Their attachment was not of recent origin, and they got married when he became rich and a titled gentleman.
* King Stephen and Queen Anne in ''Literature/TheDeathGateCycle''. Theirs was a politically ArrangedMarriage and they hated each other at first; after that changed, they kept up the facade for use in court intrigues. (And [[SlapSlapKiss as a useful excuse for shouting matches]].)
* ''Literature/HonorHarrington'':
** The People's Republic of Haven assigned [[PoliticalOfficer political watchdogs]] to scrutinize their naval commanders. In one instance, though, the watchdog and the admiral wind up in bed and in love with each other. "Conflict of interest" doesn't ''begin'' to describe it. As in, if they'd been discovered, the ''kindest'' thing that would have happened to both would have been summary execution. The watchdog and admiral in question are [[spoiler:Eloise Pritchart]] and [[spoiler:Javier Giscard]], future [[spoiler:President and Fleet Admiral of the ''Republic'' of Haven]], and theirs is one of the most touching love stories in the whole series.
** In addition, [[spoiler: Honor and Hamish Alexander]] have a secret relationship for a while due to a number of circumstances, namely [[spoiler:a) he's already married (though his wife, who's almost completely paralyzed, approves of and even encourages their relationship), b) Hamish is Honor's superior officer and, like virtually all militaries, fraternization between Manticoran officers in the same chain of command is forbidden, and c) Honor's adopted planet, Grayson, is very religious and does not approve of out-of-wedlock sexual relations (they're not on Grayson, but Honor's high status in Grayson society could have been damaged if it were known)]]. The issue is eventually resolved when [[spoiler:Honor marries Hamish and his first wife in a polygamous marriage (not that unusual in the Honorverse), taking care of the first and last issues, and by that point Hamish is the civilian head of the military, so the second issue is no longer a problem.]]
* Christine and Raoul need to keep their relationship secret because Christine (rightly) fears what ThePhantomOfTheOpera would do if he found out.
* ''Literature/WivesAndDaughters'': There are several Secret Relationships.
** Osborne Hamley, the Squire's eldest son, is secretly in a relationship with a woman his father would never ever approve. He needs to marry a woman from a solid English family who would bring money to their family estate. [[spoiler:He married a French woman who is a Catholic, penniless, with no family or friends and who used to be a nursery-governess. They even have a child together.]]
** Roger falls in love with Cynthia and proposes, but he has to leave England for two years, so he doesn!t want her to consider it binding. She also insists that nobody knows about it. Her family knows, and Mr Gibson feels obliged to tell his father because it's an honourable thing to do.
** There are hints that Cynthia is involved in a troubled relationship. [[spoiler:She got engaged to a man who lent her money when she was fifteen, but she wants to break it off, and he doesn't want to, claiming he loves her.]]
** There is gossip in the town that Molly Gibson is involved in an ill-advised relationship that might ruin her or at least her reputation. [[spoiler:She isn't. It was just a misunderstanding.]]
* In ''Literature/TheMillOnTheFloss'', Maggie Tulliver and Phillip Wakem keep their friendship (and later, their romance) secret for over a year, due to the Tullivers' [[FeudingFamilies feud]] with John Wakem.
* David Hassid and Annie Christopher have this kind of relationship in the Literature/LeftBehind series while they're both working for Nicolae Carpathia in New Babylon, with the additional secret being that they're also Christian believers. Unfortunately, Annie was killed during Carpathia's "resurrection" in ''The Indwelling'' when Leon Fortunato called down lightning to slay the disloyal among the gatherers at the funeral.
** Before this, Buck and Chloe kept this going for ages under similar circumstances. Fred Clark's review of the series contends that the underlying fatalism of the premise (the apocalypse is God's will, and the "[[PinballProtagonist heroes]]" know that they couldn't stop it if they tried) meant there was no meaningful conflict to create tension, and the Secret Relationship plotline [[ConflictBall was put in in order to create the illusion of it]], despite there being no particular reason for them to keep it a secret at all.
* SecretRelationship: John and Ravishan naturally have to be very discreet, since homosexuality is penalized by death. They don’t ever have sex for the first time until after leaving Rathal’pesha. Nonetheless, Fikiri, spying on them out of the Grey Space at the monastery, sees them kissing and blackmails them. It also turns out that one of the other supposedly-celibate priests at Rathal’pesha is secretly married (Hann’yu, one of the few truly good people at the monastery -- Aesop: forced celibacy is bad).
[[/folder]]

[[folder:Live-Action TV]]
* ''Series/GameOfThrones'': Lord Renly Baratheon and Ser Loras Tyrell attempt to be discreet about their romance due to the homophobia which exists within Westerosi society.
* ''Series/MurdochMysteries'': It's heavily implied in "Big Murderer on Campus" that James Gillies and Robert Perry are a couple, but they try to pass off as being best friends because homosexuality was a crime in late 19th-century Canada. Inspector Brackenreid believes that the two young men are unusually close, and he even asks Detective Murdoch if James and Robert are "Just good pals, or something more?"
* ''Series/{{Friends}}'':
** Monica and Chandler milked this for almost an entire season. And the other characters found out one... by... one.
** Double-subverted in a plot where Ross is dating one of his students. They agree to keep it secret, as it's not something Ross would get fired over, but it is "frowned upon". Later, sick of keeping it secret, Ross announces the relationship to his fellow professors, who inform him he will be fired if the administration finds out (it was not just "frowned upon"). Thus, they go back into Secret Relationship mode.
* ''Series/BuffyTheVampireSlayer'':
** In season two, [[HollywoodNerd Xander]] and [[LovableAlphaBitch Cordelia]]. This is PlayedForLaughs.
** In season three, Xander and Willow briefly had a fling when they were dating Cordelia and Oz, respectively, but it was wrapped up after a few episodes.
** In season four, [[LesYay Willow and Tara]]. It is implied, but never explicitly stated, that Willow is uneasy about telling her friends she is [[SuddenlySexuality dating a girl]].
** In season six, [[TheHero Buffy]] and [[AntiVillain Spike]]. This is a case of DatingCatwoman.
* Dave and Lisa (briefly) in ''Series/{{Newsradio}}''.
* Mike and Nikki in ''Series/SpinCity''.
* Was well subverted in ''Series/NorthernExposure''. Joel and Maggie finally go to bed together, and after keeping it secret for about forty-five minutes they can't stand the subterfuge anymore and actually announce it to everyone in Roslyn's Cafe. Nobody cares.
* ''Series/{{Farscape}}'' - in the fourth season, [[OfficialCouple Aeryn and John]] conceal their relationship and fake a break-up to prevent Aeryn [[spoiler: and her unborn child]] being used against John by [[BigBad Scorpius]].
** The thing of it was, Aeryn herself was left in the dark for half a season. John had to conceal how he felt to make it look real and could only explain when an opportunity arose.
** A less pleasant example is Chiana and Jothee behind D'Argo's back. The two begin an affair because of dissatisfaction with D'Argo's plans for the future (quiet married life on a farm). D'Argo finds out the next episode and is very, very unhappy.
* In the British sitcom ''Executive Stress'', a husband and wife must hide the fact that they are married from their employer. The employer has a policy that if two employees marry, one of them must quit or be fired.
* ''Series/BattlestarGalacticaReimagined'':
** Subverted by President Laura Roslin and Admiral Bill Adama. Their close friendship (which has turned into a romantic and sexual relationship) is not really hidden at all, despite the conflict of interest that comes from the fact that they are the heads of the two branches of government in the Fleet (civilian and military). As of the back half of season four, they are living together and fairly affectionate in front of others.
** Tyrol and Boomer, probably the first example in the series. He's a chief and she's an officer. Fraternization is frowned upon, so they have to keep their relationship a secret.
** Billy and Dualla have some kind of a relationship that's not exactly public.
** Dualla and Apollo have a somewhat secret relationship before they're married.
** Apollo and Starbuck have a secret relationship after Apollo is married to Dualla and Starbuck is married to Anders.
** Cally has an affair with [[spoiler: [=HotDog=]]]. We only find out after [[spoiler: we find out that Tyrol is a Cylon and he's not the father of the baby he thought was his]].
** Baltar's relationship with Number Six prior to New Caprica is a secret.
** The secret lesbian relationship involving Admiral Cain, at least t first. Hardly a secret later on. Cain kisses Gina in front of her officers.
** The relationship between Kat and her former drug dealer.
* ''Series/{{Scrubs}}'':
** Dr.Cox and Kelso have entered into a secret friendship, which has tones of this. Kelso even describes it as "all the thrill of an affair, but without all that exhausting sex." When J.D. finds out, he's furious.
** And earlier in the series, J.D. and Elliot ''think'' their relationship is this. [[EverybodyKnewAlready It isn't.]]
--> '''Dr. Cox:''' "And, if you listen closely, you'll hear the sound of no-one caring."
* Jackie and Hyde (briefly) on ''Series/That70sShow''.
* Both of the Benjamin twins on ''Series/{{Kings}}'':
** David and Michelle: Michelle has taken a vow to devote her life to God, and in any case, her father is the King and probably wouldn't approve. (Though he may suspect...)
** Jack and Joseph: Jack is in the TransparentCloset and has been explicitly told by his father that he can't be gay and become King, but Joseph is the one person he has a genuine and reciprocal love with. [[spoiler: Then Joseph dies.]]
* In ''Series/TeenWolf'', Scott and Allison tried this, using Stiles as their liaison. It didn't work.
* In the US version of ''Series/TheOffice'', there was Dwight and Angela's relationship from the second to fourth seasons ([[spoiler:and then becoming a full-out secret affair when Angela is engaged to Andy in Season 5]]). Only Jim and Pam each find out individually, [[spoiler:and the entire office learns just before both Dwight and Angela truly break up in Season 5's "The Duel"]].
** The thing is, before Angela is dating Andy, Dwight and Angela keep it secret for no apparent reason; office relationships are not forbidden. They're just weird like that.
** For the first four episodes after the Season 6 hiatus, Andy and Erin keep their newfound relationship a secret. [[spoiler:Until they admit their relationship to everyone by the end of the episode.]]
*** However, [[spoiler:they broke up in the next episode after Erin found out about Andy's history with ''Angela.'']]
* Blair and Chuck for a few episodes in ''GossipGirl's''' first season.
* In a nod to the ''StarWars'' reference above, when Jake and Miley were secretly dating in ''Series/HannahMontana'', they used the code names Anakin and Queen Amidala.
* [[Series/TheMentalist Rigsby and Van Pelt]], since coworkers are not allowed to date.
* [[Series/SonnyWithAChance Sonny]] and Chad attempt this during the two-part episode that has them start dating. It works out about as well as one would think, and the So Random cast finds out (twice... it's hard to explain) before the second part ends. (And there was plenty of [[BadLiar bad lying]] to cover up the first reveal.)
* Series/RobinHood and Marian for obvious reasons.
* As of Season 3 of ''Series/{{Castle}}'' Esposito and Lanie have begun a relationship that they're trying to keep secret due to working together. This is failing epically, as Esposito's partner, Ryan, Castle, and Beckett have clued in.
** As of Season 5, [[spoiler: Castle and Beckett]] are doing the same thing. [[spoiler: As of the fourth episode of the season, Lanie has figured out that Beckett is dating someone but is maturely letting her have her privacy about who, Esposito is trying to figure it out, and Ryan already has.]]
* Pacey and Joey in ''Series/DawsonsCreek''.
* Jimmy Palmer and Michelle Lee on ''Series/{{NCIS}}'', though it later turned out to be an OpenSecret amongst Team Gibbs.
* On an episode of ''Series/TheWonderYears'', Kevin eventually finds his {{Adorkable}} dance partner [[{{Meganekko}} Margaret]] [[CloudCuckooLander Farquhar]] to be genuinely sweet and interesting--but on a completely different rung on the junior high social ladder--so he suggests this trope to her as a way to balance it out. She [[SubvertedTrope takes offense]].
* Jeff in ''Series/{{Community}}'' has had a couple. First season he had a brief one with [[spoiler:Slater]] before they were outed by Pierce and then in season two it turns out he had 'friends with benefits' status with [[spoiler:Britta]] for most of the year.
* Played straight between Abby and Brody in ''Series/AgainstTheWall''. Eventually revealed in-universe and Richie, both Abby's brother and Brody's cop partner, is not happy.
* ''Series/PrettyLittleLiars'' is chock full of this trope. This trope applies to practically every couple in the series, [[PortmanteauCoupleName Ezria]] being one of the more dramatic examples.
** Not to mention Spoby, Haleb, and Emaya at certain points.
* Leslie and Ben in ''Series/ParksAndRecreation'' had one of these in season 3, since Chris did not allow coworkers to date. Only Ann was privy to it, but Ron eventually found out and warned them that they were terrible secret keepers and everyone was going to find out eventually. They finally, reluctantly broke up when Leslie was given a chance to run for city counsel, knowing the scandal could destroy their careers.
* The entire relationship of Quinn and Logan on ''Series/{{Zoey 101}}'', since both were embarrassed to be dating each other. They were quite succesfull in keeping it a secret, actually their big reveal at the Prom, when they came clean about their romance, did come as a shock to everyone present at the moment.
* When Doug and Carol reconcile on ''Series/{{ER}}'', they initially try to keep it a secret, due in part to Carol's hesitancy to fully commit(given Doug's [[TheCasanova previous track record for playing around]], quite understandable). At the Christmas episode, she is confident enough in their relationship that she and Doug announce that they got back together at the staff Christmas party. Turns out most of the staff knew and had a running pool going as to when they would admit it!
* On ''Series/{{JAG}}'':
** In the [[Recap/JAGS01E0102ANewBeginning Pilot Movie]], Lt. Arutti was secretly [[spoiler: married to Painter.]] They kept it a secret because the Navy would not have allowed them to serve in the same unit.
** In "[[Recap/JAGS01E10Boot Boot]]", between [[spoiler: Sergeant Gonzalez and Major Klein.]] Harm decides to overlook it on the condition that [[spoiler: they will turn themselves in if Sergeant Gonzalez is not accepted into the officer commissioning program, which she was previously mentioned to be a shoe-in for.]]
* ''Series/TheWalkingDead'': Lori and Shane, [[ReallyGetsAround Shane]] and Andrea, Glenn and Maggie...
* In season one of ''Series/VeronicaMars'', Veronica and Logan keep their relationship secret to postpone social backlash. Veronica is a FallenPrincess in a town ruled by the RichBitch and {{Blue Blood}}s, and Logan is ''one'' of those rulers.
* Barney and Robin in ''Series/HowIMetYourMother'' go the entire summer without their friends knowing about their FriendsWithBenefits arrangement (Future!Ted admits in a later episode that the other three were really, really passing around the IdiotBall that summer). She says it's because they didn't want Lily forcing them to have [[RelationshipUpgrade The Talk]], but he admits the lie just turned them on.
** This trope is also inverted in the second season of the show. Ted and Robin mutually decide to break up because they both want different things out of life, but they pretend to still be a couple for a little while longer because they don't want the news of their breakup putting a damper on Lily and Marshall's imminent wedding.
* Arthur and Gwen in ''Series/{{Merlin}}'' until the end of season 3 when they start making out in front of the castle.
* Luke and Lorelai on ''Series/GilmoreGirls'', where they had sex in Luke's apartment above his diner. They were found out when Lorelai went down to the diner for a cup of coffee early in the morning wearing one of Luke's shirts, forgetting the diner would be open for breakfast and full of customers. Many other secret relationships such as Rory and Dean in the beginning, Rory and Jess while she was still dating Dean, Rory and Marty when one of Rory's friends was dating him (they never dated but later Marty pretended he had never even met Rory), Lane and almost anyone because Mrs. Kim never approved, Lorelai and Max because he was Rory's teacher, Lorelai and Digger because he worked with Richard, Lorelai and a guy from her night school because he was so young, and Lorelai and Christopher when she thought no one would approve.
* ''{{Longmire}}'': Cady and Branch. It's a bit awkward since Cady is the daughter of the same man that Branch is opposing in the elections for sheriff.

* Curly and Laurey in ''Theatre/{{Oklahoma}}''. Inevitably, their duet "People Will Say We're in Love" is reprised as "Let People Say We're in Love."
* Jason and Peter in ''bare: a pop opera'' have one of these.
* In ''Street Scene'', Mrs. Maurrant goes to lengths to conceal [[CheatingWithTheMilkman her affair with Sankey]] from others. Unfortunately, most of her neighbors already know about it.

[[folder:Videogames]]
* In the execrable FullMotionVideo game ''{{Phantasmagoria 2}}'', the protagonist Curtis insists on this with his co-worker girlfriend. [[spoiler: Which paves the way for freaky BDSM sex with the only other female co-worker.]]
* ''{{Persona 3}} Portable'': This is the Female Main Character and Ken's relationship because [[{{Shotacon}} of the normal reaction]] [[MayDecemberRomance to a 16 and 10 year old couple.]] You can suggest coming out, though Ken reminds you of the circumstances of doing so and tells you to keep it a secret.
** Misturu and the Male Protagonist from this game also keep their relationship secret, for she kinda [[ChildMarriageVeto just ducked]] from a ArrangedMarriage for the [[UptownGirl presumably middle-class protagonist.]]
* One option for Damien's path in ''MagicalDiary'', at the end. For the best ending, you ''have'' to keep it a secret. [[spoiler: Potsdam knows, no matter what, but she doesn't do anything besides suggest that you cover up your hickey.]] Failure to do so leads to your friends turning on you if they find out - but by this point, they've seen their worst nightmares about your relationship with him come true, so they're justified in believing that you're [[LoveMartyr suicidal and possibly insane]] for trying to continue ''any'' kind of relationship with him.
* In ''VideoGame/MassEffect3'', [[TagalongReporter Diana]] [[HotScoop Allers]]' romance is this, as she says her career would be jeopardized if her relationship with a source came to light.
* ''StarWarsTheOldRepublic'': One early quest playing as a Jedi involves a pair of Padawans in a clandestine affair (in this era, Jedi are ''discouraged'' from attachment, but not outright forbidden). The player can choose to expose them or not. The female Jedi Knight can play this straight with [[LadykillerInLove Doc]], who even offers suggestions on hiding a pregnancy. Averted with the female Jedi Counsular; Iresso may be laid-back, but he refuses to break the law or get the Consular in trouble.

* The DatingCatwoman variation is used in ''EvilInc.'', where [[spoiler:Captain Heroic and Miss Match]] are married despite being a hero and a villain. Only their son, their parents and one of his allies knows. Additionally, each set of parents has never met the other set due to the risk of conflicts.
* In ''YuMeDream'', this happens a couple of times:
** Lia asks Fiona not to date James, but when James asks, Fiona can't seem to say no, even though she wants to and has made a promise.
** Jake and Don's relationship is secretive because Jake's parents are anti-gay and because Jake goes to a Catholic high school.
** When Lia and Fiona do start dating, Lia asks Fiona to keep it a secret [[http://rosalarian.com/yume/?p=475 here]] and [[http://rosalarian.com/yume/?p=483 here]]. It does cause some strain in their relationship, as seen [[http://rosalarian.com/yume/?p=525 here]].
* In ''BetweenFailures'' one of these has begun between [[spoiler:Thomas and Carol]].
* Winsbury and Janet in ''Webcomic/GunnerkriggCourt'', [[spoiler:at least, until TheReveal is made in Chapter 34]]. In-comic, it's not clear exactly why its a secret; perhaps the fact that Janet is the Headmaster's daughter has something to do with it. Out-of-comic, it's a reference to the folk song "Willie O'Winsbury" (Literature/{{Child Ballad|s}} #100). The Willie and Janet from the song keep it a secret because Janet's dad is the King. WordOfGod stated that the couple is hiding the fact that they're also "romantic dorks" [[spoiler:which they ''also'' reveal in the strips immediately following the initial reveal]].
* Nanase and Ellen in ''Webcomic/ElGoonishShive'': Immediately subverted in that [[EveryoneCanSeeIt all of their friends had figured it out way before they did]] and were only keeping quiet to allow Nanase time to work through her feelings. It's still a secret from everyone else, though.
* Bruno and Corrie in ''WebComic/KevinAndKell'': in the early years, [[http://kevinandkell.com/1996/kk0104.html Corrie rode on Bruno's back disguised as a sheepskin.]]
-->'''Corrie:''' So when you gonna tell 'im 'bout us?\\
'''Bruno:''' Patience, my sweet.
* Fido and Sabrina in ''WebComic/{{Housepets}}'' It was a serious taboo for them to have a relationship, especially with Fido's status as a role model for the dogs of Babylon Gardens and a K-9 Officer. Fido finally [[{{Pun}} let the cat out of the bag]] [[http://www.housepetscomic.com/2013/10/30/le-gasp/ on live television to thwart an]] ArrangedMarriage.
** The fallout is still ongoing, but it doesn't appear it will have a long-term effect on his career (outside a three-week suspension for the fight with Jata). In fact, [[http://www.housepetscomic.com/2013/11/22/blue-lines-and-red-tape/ his superior, Sergeant Ralph, appeared relieved by the revelation]], [[CouldHaveAvoidedThisPlot and was only disappointed that he wasn't warned beforehand about what Fido was about to do]].
--->'''Sergeant Ralph:''' I've had my eye on you for a while. Your suspicious behavior ''worried'' me. I thought you were participating in something underhanded--or worse, ''illegal''. Who you decide to snuggle with after hours is none of the department's business nor concern.

* In ''Roleplay/TheGamersAlliance'', the mage [[ManipulativeBastard Belial]] and Sultana [[LadyOfWar Razia]] have a secret affair. They can't make it public due to the political ramifications of a [[ProudWarriorRaceGuy Sarquil]] ruler being intimate with a foreigner, which would be frowned upon in the court. They're eventually discovered, however, which leads to a coup in which Razia's twin sister [[WomanScorned Adela]] kills her and takes over the throne while Belial and his bastard children [[JerkWithAHeartOfGold Khalid]] and [[IHaveNoSon Sumrah]] are sent into exile to Belial's homeland.
* In the web series ''ShadowOfTheTemplar'', both Simon and Jeremy keep their relationship a secret from everybody else. That's probably a good thing, because one is an FBI agent and one is a high profile GentlemanThief. [[spoiler:Thoroughly subverted in ''High Fidelity'' when Simon admits to his team and to his boss the nature of his relationship with Jeremy.]]
* In ''Literature/LovelaceOneTwo'', Andi figures out that [[spoiler:Mr. Stone and Ms. Seok]] are secretly an item.

* Principal Skinner and Edna Krabappel on ''TheSimpsons'': they keep it a secret for half an episode, get found out, get fired, hold the empty school hostage, then pretend to break up. Afterwards, they (literally) put their relationship back in the closet, with varied degrees of secrecy after that. It's one of the few Simpsons plots not completely affected by NegativeContinuity.
** Edna and Ned Flanders tried to keep their relationship a secret too. Or at the least, until Edna unintentionally revealed that she and Ned eloped some time ago.
* Jake and Rose form one within the DatingCatwoman scenario in Disney's ''AmericanDragonJakeLong''.
* Shaggy and Velma in ''[[ScoobyDooMysteryInc Scooby-Doo: Mystery Incorporated]]''. At first it seems like Shaggy's just afraid of commitment and using Scooby as an excuse, but his reasons for keeping the relationship a secret become more understandable once we see Scooby's hostile reaction to having Shaggy ditch him to take Velma to the prom.
** Actually it is suggested that Scooby was fully aware of their relationship and approved of it, right before Shaggy ditched their movie night without telling him.
* ''KickButtowski'' gives us Kendall and Ronaldo, after Kick finds out about them in "Frame Story"... albeit, even the viewers are confused about wether they're together or not, consistently. Since that episode there have been numerous episodes in the second season where they're still dating, yet Kendall either breaks-up with Ronaldo, prefers Kick and even cheats on him behind his back ('''literally''' behind his back).
* ''WesternAnimation/YoungJustice'' Season 2 reveals that [[spoiler:Red Arrow and Cheshire]] developed one during the TimeSkip, including a (probably) secret marriage and a kid.
** In Season 1 Superboy and Miss Martian tried to keep their relationship secret...and failed, ''hard''. Only two people actually needed the relationship pointed out to them and both times literally pointing in their general direction provided all the proof needed.
* Continuing off of the [[Franchise/StarWars movies]], ''WesternAnimation/StarWarsTheCloneWars'' even goes so far as to [[DeconstructedTrope deconstruct]] Anakin and Padme's relationship in the "Lost Missions" episode, "Rise of Clovis". When Padme's old flame, Rush Clovis, shows up and she starts getting close to him to get some information, this does not sit well with Anakin, who can't really say she's already married to him since he isn't supposed to be married in the place. After he nearly beats Clovis to death in a fit of [[CrazyJealousGuy jealous]] [[{{Yandere}} rage]], Padme not only calls him out on him going too far with his possessiveness, but on how screwed up their relationship actually is. They aren't able to do the things that legit married couples get to do and there's some distrust between them. As a result, she decides that they should stop seeing each other for awhile ([[ForegoneConclusion which only lasts seemingly until the end of the next episode]]).

* Romeo and Juliet could have learned a few valuable lessons from Ferdinand of Aragon and Isabella of Castille, who determined to unite both themselves in marriage and their kingdoms into the unified Spain. This they accomplished in defiance of both their families and the Church's ban on marriage between [[KissingCousins second cousins (which is what they were)]] besides through numerous secret letters sent to each other, a couple of clever ruses, Ferdinand disguising himself as a traveling merchant at one point, and a Papal Bull of dubious authenticity. In addition to their success in consummating their secret relationship, they also proved to be very cunning political partners. Seriously, their history sounds a lot like what Romeo and Juliet's tale might have been like if Niccolo Machiavelli had written it instead of Shakespeare. Today, ''every'' Royal House in Europe is descended from them - usually many times over.
* Australian astronomer Ruby Payne-Scott was forced to marry in secret because the law did not permit married women to hold a permanent position in the Commonwealth public service. She was eventually discovered and forced to leave her position, despite being a pioneer in the development of radiophysics and radio astronomy.
