One Direction (commonly initialized as 1D) is a British-Irish BoyBand formed in London, England. Originally, the boys auditioned for the seventh series of ''Series/TheXFactor'' as individuals. They were assembled into a group by Simon Cowell, who became their mentor throughout the show. After placing third, Cowell signed One Direction to his own record label in 2010.

Since then, the band has skyrocketed to worldwide fame, releasing many hit singles, winning numerous awards, and unseating Music/JustinBieber as the biggest teen heartthrobs in the world. After five years of world domination, 1D have become the most successful boy band to ever come out of either the UK or Ireland[[note]]Not counting, of course, Music/TheBeatles, whose status as a boy band is highly disputed[[/note]].

In March 2015, it was announced that Malik had left the band and that the other four members would be continuing. Then in August, it was announced that the band would go on hiatus (officially not a split) following the release of their fifth album the following year. A generation of fangirls mourned, as ever.

!!Members of One Direction include (from left to right in the picture):
* Louis Tomlinson - born December 24, 1991 in Doncaster, South Yorkshire. (2010-)
* Liam Payne - born August 29, 1993 in Wolverhampton, West Midlands. (2010-)
* Music/HarryStyles - born February 1, 1994 in Holmes Chapel, Cheshire. (2010-)
* Niall Horan - born September 13, 1993 in Mullingar, County Westmeath, Ireland. (2010-)
* Music/ZaynMalik - born January 12, 1993 in Bradford, West Yorkshire. (2010-2015)
* ''Up All Night'' (2011) - 1D's first album. Upon its U.S. release in March 2012, they became the first U.K. group to debut at #1 on the U.S. ''Billboard'' 200 with a debut album.
* ''Take Me Home'' (2012) - One Direction is one of the very few groups to have debuted at the top with both of their first two albums. The only ones to do so prior to them were GirlGroup Danity Kane and Music/{{Eminem}}'s rap troupe D12.
* ''Midnight Memories'' (2013) - One Direction became the first (and to date, only) group to debut atop the ''Billboard'' 200 with each of their first three albums. The last group to even ''reach'' the top with its first three albums were Music/TheMonkees in 1967.
* ''Four'' (2014) - 1D's [[ExactlyWhatItSaysOnTheTin fourth]] album. Like the previous one, it set a record for its number-one debut and had the no-longer-boys GrowingTheBeard.
* ''Made In The AM'' (2015) - Despite this being the band's fifth album in as many years, it is their first as a quartet, as a result of Zayn Malik's departure in March 2015. In accordance with ''Four'', this album completes the GenreShift from teen pop to a more rock-oriented style. Also, it is their first album not to go #1 on the Billboard 200, having been blocked by Music/JustinBieber's ''Purpose''.

* AlbumTitleDrop:
** ''Take Me Home''[='=]s title comes from a line in "Kiss You": ''"If you don't wanna take it slow/And you just wanna take me home/Baby say yeah yeah yeah yeah yeah yeah/And let me kiss you."''
** Also present in ''Made In The AM''[='=]s final song, "AM": ''"All my favorite conversations, always made in the AM."''
%%* AntiLoveSong: "Tell Me A Lie", "Taken".
* AscendedExtra: Louis and Niall sang mostly backup, save for a few token solo lines on their first album; lead vocals were shared between Liam and Harry and (to a lesser extent) Zayn. Fans lobbied for them to get bigger parts and got their wish from the second album on.
* AscendedFanboy: Niall idolized Music/JustinBieber before One Direction was formed and cited him as an influence during his ''X Factor'' audition. Since then, they've hung out several times and tweeted pictures together. Additionally, One Direction's level of success has rivaled and arguably exceeded Bieber's.
* BandToon: Click [[http://www.youtube.com/watch?v=1o3fcUH-yPQ here]] to watch ''The Adventurous Adventures of One Direction''. [[CrowningMomentOfFunny You're welcome]].
* BoyBand: Their most defining characteristic. While their record sales trail the Music/BackstreetBoys and Music/{{NSYNC}}, One Direction is said to have a larger fan base than their predecessors. While One Direction are significantly behind Music/TakeThatBand's success in their homeland, they have eclipsed them everywhere else.
%%* BreakupSong: "I Should Have Kissed You", "Heart Attack", and "Summer Love".
* CallBack: "They don’t know about the up all nights" from "They Don't Know About Us" references the title of their first album.
* {{Camp}}: Their "[[http://www.youtube.com/watch?v=T4cdfRohhcg Kiss You]]" video, to great success.
* ChronologicalAlbumTitle: "Four" is unique among their discography as this
* CoverVersion: During their run on ''Series/TheXFactor'', they covered everything from Music/EltonJohn to Music/{{Rihanna}}.
** TheCoverChangesTheGender: Their versions of Ednaswap's "Torn" and Rihanna's "Only Girl in the World".
* CrowningMomentOfIndifference: When Harry, Liam, and Niall were [[http://www.youtube.com/watch?v=9tSSQHQ5Ts0 tricked into believing a woman was going into labor]] on the studio floor, Niall could not have been more apathetic.
* CurbStompBattle: Their 2014 BRIT Music Video award was a particularly jarring example. More than 1.7 million votes were cast in the span of ''less than two hours''. Not only did their [=#BRITsOneDirection=] hashtag top the Worldwide Website/{{Twitter}} trends, but they were the ''only'' one of the five nominees to even make it onto the trending list. Twitter reveals that a whopping ''93%'' of all votes in this contest were for One Direction.
** What's even more painful for the losers is the Brits' decision to go global that year? Had the awards ceremony remained a domestic event, One Direction, while still likely to win the award, would probably have had far less than 93% of the vote.
* DigitalPiracyIsEvil: Savan Kotecha, one of One Direction's song writers, addresses this.
* DisguisedInDrag: [[http://25.media.tumblr.com/c295a47f1f52605775e11db1f1d8a961/tumblr_mq83khbh3h1r5pm10o1_500.png Zayn]]. Played straight [[AttractiveBentGender rather successfully]] in the "Best Song Ever" music video.
* GenderNeutralWriting: The majority of their songs are addressed to an ambiguous, inclusive "you" that is only assumed to be female.
** Notably, [[http://www.entertainmentwise.com/news/124462/Harry-Styles-Reveals-His-Dream-Girl-Someone-With-A-Cute-Laugh-And-A-Good-Smile in interviews]] that [[http://29.media.tumblr.com/tumblr_m210oi9b401qllex3o1_500.png ask]] about [[http://25.media.tumblr.com/tumblr_m25ye0J8yK1qclaf7o1_500.png their preferences]] in women, Harry often says that he would want "someone" who... or he likes "people" that... instead of specifying if his preferences are for males or females.
** Even more relevant since Harry's comments about gender being "not that important" when looking for a potential lover, and telling Niall "don't knock it til' you try it" when talking about sleeping with another man.
* GenreRelaunch: They, Music/BigTimeRush and Music/TheWanted have brought boy bands back into the mainstream, full force -- but since they became an *NSYNC-level phenomenon whereas the latter two groups were generally unsuccessful, they are usually given credit alone.
%%* ICantDance: [[http://www.youtube.com/watch?v=wwk2tPauT_s Just watch this.]] Or [[http://www.youtube.com/watch?v=_yiie5PWbGc this.]]
%% Weblinks are not examples.
%% * IntercourseWithYou:
%% ** "Rock Me" could be interpreted this way.
%% ** "Kiss You" ("If you don't wanna take it slow/ And you just wanna take me home/ Baby, say yeah, yeah, yeah").
%% ** "Live While We're Young", with its "get some" lyric).
%% Zero-context examples are forbidden.
* {{Irony}}:
** The band's SignatureSong is "What Makes You Beautiful", which has the lines "don't need makeup to cover up, being the way that you are is enough", yet One Direction once released a line of makeup.
** "What Makes You Beautiful" is about a girl who doesn't know how beautiful she is, whilst Niall Horan's solo song "One The Loose" features a woman who acknowledges her beauty and uses it to draw attention to herself
* IWantSong: [[ExactlyWhatItSaysOnTheTin "I Want"]]. DoubleSubverted in that most of the song isn't about what the guys want, but about admonishing a girl who is selfish and materialistic and them wanting a girl who will just love them.
%% * LittleBlackDress: "''…just walked into the room.''"
* LoopedLyrics: Quite a few...
** "''I want, I want, I want''..."
** "''I shoulda, I shoulda, oh, I shoulda kissed you / I shoulda, I shoulda...''"
* LyricalShoehorn: The bridge of "What Makes You Beautiful" consists entirely of "na na na's".
* TheMovie: ''This Is Us'' was released August 2013.
* MrFanservice: All of them to an extent, though some more than others. Liam especially has been turning this up to eleven in his solo career.
* OdeToYouth: "Live While We're Young".
* OneWomanSong: "Diana" and "Olivia"
* PelvicThrust: Often done in sync with all of them, but Harry particularly seems to have a bit of a thing for this
* PissTakeRap: They do a rap-rhyming thing in the verses of "Over Again".
* PrecisionFStrike: "A.M." from ''Made in the A.M.'' drops the first ever swear word to be used in a One Direction song: "''We're just swimming 'round in our glasses / and talking out of our ''asses''''".
* PreppyName: From "Best Song Ever": "''Said her name was Georgia Rose / And her daddy was a dentist.''" If you are English and your name is Georgia, then daddy is more likely to be a dentist than a docker.
* RefrainFromAssuming: Niall's debut solo single "This Town" is not called "Everything Comes Back to Me".
* TheRunnerUpTakesItAll: They are by far ''The X Factor''[='=]s most successful act.
* ShoutOut:
** Listen to the opening beat of "Rock Me" and think of [[Music/{{Queen}} what it sounds like]].
** "Better Than Words" name drops popular love songs from the past several decades.
** The opening riff of "What Makes You Beautiful" does this to ''Film/{{Grease}}''[='=]s song "Summer Nights".
* SillyLoveSongs: "What Makes You Beautiful", "One Thing", "Live While We're Young"... they make a lot of these.
** "Better Than Words". Bonus points for the fact that its verses ''entirely consist'' of titles from other silly love songs..
* SongOfSongTitles: Almost every word of the verses of "Better Than Words" is a reference to one song or another
* SpearCounterpart: To Music/FifthHarmony, since they both have 5 members (or at least did until Zayn left 1D and Camila left 5H) and they both started out on the ''X Factor'' (the former in the US version, the latter in the UK version). They both consisted of five solo artists who were put into a group after getting rejected, they both finished third, and they have similar shorthand names (5H and 1D). One member of each group (Zayn & Camila) left the band in their fourth year. The only differences are that 5H is American, and they have a more 'urban' bend while 1D is closer to adult contemporary.
** As of Zayn's departure, they are also this to Music/LittleMix - both British, both 4-member groups, both also on the UK ''X Factor'' -- although Little Mix won their series and 1D didn't. Ironically, Zayn was engaged to Perrie before quitting the band.
* StudioChatter: The start of "Olivia" from "Made in the A.M."
* TitleTrack: The song "Up All Night" from their debut album and "Midnight Memories" from their third album are examples of this. ''Take Me Home'' subverts this, but a title drop can be found in "Kiss You". Subverted completely with "Four", but "A.M" on "Made in the A.M." uses the album title in the song
* VocalTagTeam: Liam and Harry clearly had the most solos on their first album, ''Up All Night'' ([[http://www.thehitsradio.com/music/features/one-direction-facts/ see #28]]). Later albums are more even-handed.
