->''"Tighten your grip on the Doctor’s timeline and it becomes sand. And much like sand, the Doctor gets everywhere and needs an awful lot of cleaning up after."''

In late 1963 we had ''Series/DoctorWho'', the series which spawned the {{Whoniverse}}. Then in 1964, in the pages of ''TV Comic'', a ''Doctor Who'' spin-off comic started. It was the first part of what would become the ''Doctor Who'' ExpandedUniverse: a never-ending supply of stories with many different branches, timelines and continuities, which have a strong tendency to reference each other and mutually contradict each other in the same breath. Their canonicity to the TV series is "debatable" and very, very complicated.

A couple of ExpandedUniverse stories and characters have been directly adapted into (or just referenced in) TV series episodes. And many ExpandedUniverse stories and characters are adapted into ''other'' ExpandedUniverse stories and characters, which are then adapted for TV, which then spin off into more ExpandedUniverse stories... you get the idea.

The Expanded Universe has branched in diverse ways into separate fully licensed and semi-official sub-continuities, divided (in some cases) by the BBC's copyright restrictions. This is further complicated by the fact that no one person, including the BBC, owns all the rights to the monsters and characters which have appeared in the Whoniverse. Sometimes the varying franchises acknowledge each other, sometimes they ignore each other, DependingOnTheWriter. In one notable instance, AudioPlay/BigFinishDoctorWho explicitly named the Literature/EighthDoctorAdventures as an alternate timeline that takes place in an AlternateContinuity, before -- a few years later -- referencing them ''and'' the canonically incompatible ''Magazine/DoctorWhoMagazine'' comics as canon anyway. The TimeyWimeyBall, BroadStrokes and especially the MST3KMantra apply where necessary.

ExpandedUniverse material in general and without the Doctor, in particular, tend to be DarkerAndEdgier and skew more towards the cynical end of the SlidingScaleOfIdealismVersusCynicism than their parent series. The different Sarah Jane spin-offs serve as a lesson in how you can spin off the same character in different ways, using different tropes and for different audiences: the ThirdDoctorRadioDramas have her as a DamselInDistress; ''Series/TheSarahJaneAdventures'' and ''Series/{{K-9 and Company}}'' are notably fluffy and sweet (with still pretty dark themes for children's television of their respective times); the semi-professional direct-to-video fanmade production ''Downtime'' tackled a few more serious issues; the ''AudioPlay/BigFinishDoctorWho'' audio adaptation series ''AudioPlay/SarahJaneSmith'' is dark, mature and complex.

The "wilderness years" also spawned numerous FanWork stories, typically involving the then-cancelled TV series' actors and crew in some way. These include the DoctorWhoAudioVisuals (which eventually became the official Creator/BigFinish production studio) and various BBV productions. The people responsible for these FanWork productions ended up directly involved in ''Doctor Who'' proper, and many of the concepts became AscendedFanon.

In short: the ''Doctor Who'' Expanded Universe is a never-ending rabbit hole of stories. It's all tangled and full of BroadStrokes, and those who expect consistency, or even, in some cases, sanity, are in for a confusing ride. But the sheer importance and impact of the ExpandedUniverse to the TV series proper is tremendous: numerous post-2005 {{Whoniverse}} writers (and quite a few actors) got their start in ''Doctor Who'' in its expanded universe, and everyone involved with the show has been heavily influenced by the stories.


* ''TV Comic'': This British AnthologyComic publication specialised, as its name suggests, in comic strips featuring licensed TV characters. It ran a ''Doctor Who'' strip from 1964 to 1979, with a break during 1971-3 when the ''Doctor Who'' strip appeared in a sister title called ''Countdown'' and later ''TV Action'', aimed at a slightly older audience. However, all these strips were definitely commercial publications aimed at a child audience, and the stories featuring the first four versions of "Dr. Who" and his companions (who in the early days were entirely different from the TV characters, due to the publishers only paying the fee to use the Doctor himself) reflected this. Apart from sharing very basic elements, they didn't have much in common with the television series. At one point, the Doctor joins forces with SantaClaus to battle an evil wizard and save Christmas.
* ''TheDalekChronicles''. This comic ran in the [[{{Supermarionation}} Gerry Anderson]]-linked anthology title ''TV Century 21'' from 1965 to 1967, featuring the Daleks in general and the Emperor Dalek in particular as the {{Villain Protagonist}}s, killing and destroying everything in sight. This strip owed its existence to the fact that Creator/TerryNation personally owned the copyright in the Daleks and initially licensed them separately. For its time it was distinctly DarkerAndEdgier than the main ''Doctor Who'' strip, and was partially written by the first script editor of ''Doctor Who'', David Whitaker. It has a much higher reputation among fans than the early ''Doctor Who'' strips, and parts of its content undoubtedly influenced plots and Dalek characterisation and tech in later TV stories. Examples include the Emperor Dalek and, of course, the storyline about the nonconformist (though still violent) hippy Dalek who decided to go against the Emperor and defend pretty things -- to the death! (The latter storyline appeared, minus the silliness, in the television story "The Evil of the Daleks".) The later ones have some excellent artwork by Ron Turner.
* ''Magazine/DoctorWhoMagazine'': From 1979 onwards, and still ongoing. By and large, the DWM comics have tended to reference their own sub-continuity more than other media. However, during the early 1990s, they shared the same continuity as the Literature/DoctorWhoNewAdventures novels; in the mid-90s, around the time of the TV Movie, they made a break with the novels' continuity by killing off the Doctor's companion Ace as a teenager (after the books had shown her to age, turn into a NinetiesAntiHero and finally leave the Doctor for good).
** ''AbslomDaakDalekKiller'': Published in ''Doctor Who Magazine''. A BarbarianHero InSpace, doubling as both SpaceOpera and a partial {{Deconstruction}} of AntiHero tropes. It starred a rather dim-witted AxCrazy[=/=]IneffectualLoner on a perpetual RoaringRampageOfRevenge against the Daleks, who had exterminated his lover, a RichBitch FallenPrincess (''literally'' a princess, in her case. After her extermination she ended up unalive in a cryo-chamber.). He lived during the same 26th century time period as BerniceSummerfield, and met her twice.
* ''Magazine/RadioTimes'' comic strip: A short-lived Eighth Doctor strip written by Gary Russell with art by Lee Sullivan. It ran for about a year in ''Radio Times'' after the TV Movie, and ended up getting CutShort. (Gary would later wrap up the story as a side-plot in his Literature/EighthDoctorAdventures novel ''Placebo Effect''.) Format-wise, it was more akin to a newspaper comic than anything else, with short strips generally cliffhangering into the next one.
* ''Magazine/DoctorWhoAdventures'': After the TV series' return in 2005, a new magazine aimed at kids came out alongside DWM, with its own LighterAndSofter comic.
* ''IDW Comics'': American company Creator/IDWPublishing picked up the licence for US ''Doctor Who'' comics after the export success of the 21st-century revived series, reprinting the ''Doctor Who Magazine'' run from the beginning as ''Doctor Who Classics'', producing their own one-shots and miniseries, and eventually launching their own separate ongoing series. IDW's issues are officially NoExportForYou to the UK, for licencing reasons, although it's easy to find the [=TPBs=] in comic shops. Their ''Doctor Who'' licence [[http://us1.campaign-archive1.com/?u=5792cac24346d164eb0cf6ad2&id=49c9eb6eb4 ended]] at the same time as Creator/MattSmith's tenure on the show. Their releases included, but are not limited to:
** ''ComicBook/DoctorWhoTheForgotten'': A longer story arc featuring all ten (at that point) Doctors.
** ''ComicBook/StarTrekTheNextGenerationDoctorWhoAssimilation2'' (2012): A ''Series/StarTrekTheNextGeneration'' crossover miniseries, and thus also part of the Franchise/StarTrekExpandedUniverse.
** ''ComicBook/DoctorWhoPrisonersOfTime'': A special for the 50th anniversary.
* [[ComicBook/BBCBooksDoctorWhoGraphicNovels Doctor Who graphic novels]]: Published by the BBC.
* Titan ''Doctor Who'' comics: After IDW lost the US ''Doctor Who'' comics license, Titan Books, previously known mostly for publishing ''ComicBooks/TwoThousandAD'' strip collections, were the next recipients. They are publishing three separate ongoing series featuring the Tenth, Eleventh and Twelfth Doctors.

[[folder: Film]]
* ''Film/DrWhoAndTheDaleks'' (based on "The Daleks") and ''[[Film/DaleksInvasionEarth2150AD Daleks' Invasion Earth 2150 A.D.]]'' (based on "The Dalek Invasion of Earth"): Two colour, relatively high budgeted ''Doctor Who'' [[TheFilmOfTheSeries film adaptations]] from the 1960s. The films, starring Creator/PeterCushing, [[CompressedAdaptation shortened]] and [[ViewersAreMorons dumbed down]] the stories, meaning that they cut out much {{Padding}}, but simplified the themes, softened the characters and overall made things LighterAndSofter. The Doctor underwent {{Flanderization}} into a human AbsentMindedProfessor ''[[IAmNotShazam literally]]'' [[IAmNotShazam called Dr. Who]] who had invented a time machine called ''TARDIS'' (no "the"). His grand-daughter Susan was de-aged to prepubescence and Barbara and Ian were changed from teachers to Doctor Who's grown-up elder grand-daughter and her incompetent PluckyComicRelief boyfriend. The second film replaced Barbara and Ian with Doctor Who's niece Louise and Tom Campbell, a bumbling policeman who anticipated a couple of TV companions by stumbling into ''TARDIS'' thinking it was a real police box. Needless to say, they occur in a AlternateContinuity from the series. At least one official prose spin-off short story has been published featuring the movieverse characters. Bernard Cribbins, who played Campbell, played Donna's grandfather Wilfred Mott in several Davies-era TV stories, decades later. Creator/StevenMoffat, showrunner of the main series, has cited the movie Daleks as inspiration for the Dalek design of series 5.
* BBV movies: Semi-pro direct-to-video licensed videos starring TV series companions and monsters, including:
** ''Wartime''
** ''Downtime'' (also integrated into the Missing Adventures continuity; introduced CanonImmigrant Kate Stewart)
** ''Shakedown: The Return of the Sontarans'' (also integrated into the New Adventures continuity)
** ''Mindgame''
** ''Dæmos Rising''
* "Global Conspiracy": A short {{Mockumentary}} by Creator/MarkGatiss, based on and released on the DVD releases of "[[Recap/DoctorWhoS10E5TheGreenDeath The Green Death]]".

[[folder: Television]]
Most TV spin-offs are unambiguously in the continuity of the main TV series: this section is for TV oddments whose continuity was ambiguous even at the time of production.
* "[[Recap/DoctorWho1985JFIGSAFixWithSontarans A Fix With Sontarans]]": A crossover with ''Jim'll Fix It''.
* "Search Out Space": An episode of a children's educational show ''Search Out Science'', featuring the Seventh Doctor, Ace and K-9 in character in original scripted material.
* "[[Recap/DoctorWho30thASDimensionsInTime Dimensions In Time]]": The 30th anniversary special, doubling as a a crossover with ''Series/EastEnders''.

[[folder:Animation/Web Original]]
!Animation/Web Original

In the 1980s, Canadian company Nelvana planned to produce an animated ''Who'' series for American network CBS, which fell through. Early concept art for the series featured a Doctor who bore a striking resemblance to Egon Spengler, from ''WesternAnimation/TheRealGhostbusters''.

About a decade after ''Series/DoctorWho'' went off the air, [=BBCi=] started experimenting with the series, doing webcast dramas with animated elements. These include:

* ''WebAnimation/DeathComesToTime'': set in an apparent AlternativeContinuity which ignores the TV Movie with the Eighth Doctor as well as the novels.
* "[[Recap/DoctorWhoS17E6Shada Shada]]": A TV episode that got stuck in DevelopmentHell and was later recorded by Creator/BigFinish, with the Eighth Doctor taking the place of the Fourth.
* "[[Recap/BigFinishDoctorWhoSpecialsRealTime Real Time]]": recorded by Creator/BigFinish, starring the Sixth Doctor and Creator/BigFinish companion Evelyn. Notably the first cooperation between Creator/ColinBaker and the BBC since he got ScrewedByTheNetwork.
* ''WebAnimation/ScreamOfTheShalka'': A 2003 anniversary special by [=BBCi=], which featured a Ninth Doctor played by RichardEGrant. The TV series' return (announced two months earlier), however, meant the Shalka Doctor got overwritten in continuity. It also had a {{cameo}} by [[Creator/DavidTennant a now somewhat well-known Who fan]] who basically insisted on having a part written just for him after hearing about the production from down the hall.
* ''[[Recap/DoctorWho2007TDWASTheInfiniteQuest The Infinite Quest]]'': a 13-part serial featuring the Tenth Doctor and Martha, broadcast as part of the BBC kids' series ''Totally Doctor Who''.
* ''[[Recap/DoctorWho2009ASDreamland Dreamland]]'', a 2009 [[AllCGICartoon CGI-animated]] serial featuring Ten solo with "guest companions". Initially, it was shown on digital and online, before appearing on BBC Two. This is almost certainly in mainstream TV continuity, as one of its villain factions later turned up in ''Series/TheSarahJaneAdventures''.


* ''Literature/DoctorWhoNovelisations'': By Target. During the 70s and 80s, in the days before video took off, these were '''the''' way to catch up on previous ''Doctor Who'' stories. They retold (and frequently expanded on) the stories on TV, and several of them are highly acclaimed. Usually also available as audiobooks, read by the TV series actor(s). Almost every story from the classic series got a novelisation, with the TV Movie's being done by BBC Books; the five that didn't get one ("The Pirate Planet", "City of Death", "Shada", "Resurrection of the Daleks" and "Revelation of the Daleks") received fan novelisations courtesy of the New Zealand Doctor Who Fan Club. (If you noticed that three of the five are Douglas Adams stories, you're right. Adams wouldn't allow others to novelise his scripts, and -- notorious procrastinator that he was -- never did them himself. Also, with ''Franchise/TheHitchhikersGuideToTheGalaxy'' having taken off in the meantime, Target Books was no longer able to afford the advances he commanded.) "Shada" eventually received an official novelisation by BBC Books in 2012, written by Gareth Roberts; "City of Death" is set to receive a BBC novelisation in 2014, again courtesy of Roberts. However, there've been no official novelisations of anything past the TV Movie, and it looks unlikely there will be.
** ''The Companions of Doctor Who'': A short-lived series of Target novels featuring [[ExactlyWhatItSaysOnTheTin companions without the Doctor]]. After original novels featuring Turlough and Harry Sullivan (the latter written by Sullivan's actor Ian Marter), it fizzled out with a novelisation of ''K-9 and Company''.
* ''Literature/DoctorWhoNewAdventures'': Created after the show was cancelled, as an official continuation of the adventures of the Seventh Doctor and, initially, Ace. Also known as "Virgin New Adventures", after their publisher. Choosing to aim for an audience of 25 and up fans and readers of ScienceFiction (versus targeting a younger, less reverent demographic, as they also considered), they made both the Doctor and the tone of the entire franchise DarkerAndEdgier. They also made the stories a bit harder on the MohsScaleOfScienceFictionHardness (the television series had gone in that direction anyway). The novels (more because of the creativity of the fans-turned-authors RunningTheAsylum than by ExecutiveMeddling) riffed over each other's contributions. Future ShowRunner Creator/RussellTDavies contributed one of the novels, ''Damaged Goods''. Other writers for the New Adventures would later write for the 2005 revival series. The penultimate New Adventures novel featuring, ''Lungbarrow'', by Creator/MarcPlatt, also went into the Doctor's secret BackStory, hinted about onscreen. After Virgin lost the licence, a few further novels featuring characters original to the series without the Doctor were published as "New Adventures", to tie up long-term arcs.
** ''BerniceSummerfield'': A SpinOff-cum-continuation of the ''Literature/DoctorWhoNewAdventures'' (not featuring the Doctor), starring a 26th century (later 27th century) AdventurerArchaeologist (and, these days, single ActionMom to her [[HalfHumanHybrid half-human]] son). Bernice had been the first original companion created for the novel series, after Ace's departure. Her solo series began after Virgin lost their license following the TV Movie. Has the odd WritingAroundTrademarks and LawyerFriendlyCameo when needed. Under the auspices of Creator/BigFinish, the series still continues, and inspired Creator/BigFinish's extremely long run of BerniceSummerfield audios.
* ''Literature/DoctorWhoMissingAdventures'': Novels starring the first six Doctors, also published by Virgin at the same time as the New Adventures featuring the Seventh. Although they were written to officially fit in between specific pairs of TV stories, and so couldn't do anything that would truly break TV continuity, they often adopted the more "mature", DarkerAndEdgier subject matter and tone of the New Adventures.
* Decalogs: A five-volume series of short story anthologies featuring the Doctor and his companions, also published by Virgin. Notably, ''Decalog 3: Consequences'' contained "Literature/ContinuityErrors", later head writer's Creator/StevenMoffat's first contribution to the franchise. Following Virgin's loss of the ''Doctor Who'' license, ''Decalog 4: Re:Generations'' focused entirely on the family history of ''New Adventures'' companion Roz while the final volume, ''Decalog 5: Wonders'', said "screw it" and was, with the exception of "The Judgement of Solomon" featuring Benny, an anthology of standalone sci-fi short stories completely unrelated to the ''Doctor Who'' franchise.
* ''Literature/EighthDoctorAdventures'': Published by the BBC. The authors ''really'' had a field day with the Eighth Doctor, who had only appeared in the MadeForTVMovie. Since his run in the TV series was so short, nearly all of his adventures had to be shown in the Expanded Universe, in the novels, audio plays and comics. General consensus says that both this series and the ''Literature/DoctorWhoNewAdventures'' took place in the same universe, though some writers disagreed. At any rate, the Eighth Doctor novels started off LighterAndSofter then before and then got DarkerAndEdgier again and engaged in heavy [[StoryArc Story Arcs]] leading to (arguably) ContinuityLockOut and eventually CosmicRetcon, which in turn led to... etc., etc. Not to be confused with Creator/BigFinish's ''New Eighth Doctor Adventures'' audio series.
** ''FactionParadox'': An EvilCounterpart (or more precisely, ChaoticNeutral counterpart) of the Time Lords who use {{Temporal Paradox}}es as a weapon. Introduced in the Eighth Doctor Adventures published by the BBC, they spun off into their own series of novels, comic books and audios in which various DiabolicalMastermind types square off against each other. This sub-universe seemed to have died, though is now putting out books and audio adventures again after a change of publisher. More adult SpeculativeFiction, this sub-universe engages in BlackAndGrayMorality, EvilVersusEvil and MindScrew at regular intervals. Also much cheeky use of mainstream Whoniverse continuity.
* ''Literature/PastDoctorAdventures'': A range of novels by the BBC analogous to the Virgin Missing Adventures, featuring the first seven Doctors (and in one instance after Creator/DavidTennant became the Doctor, but before his first full episode, the Eighth). Dropped in 2005, around the time of Creator/DavidTennant's debut, and has been revived with ''The Wheel of Ice'' in 2012 (a 7-year release gap) and ''Harvest of Time'' in 2013.
* ''Short Trips'': Short story anthologies by the BBC, later published by Creator/BigFinish. (Once Creator/BigFinish lost their licence to publish ''Short Trips'' as books, they continued making new ones as an audio series.)
* Telos novellas: Briefly, Telos got the licence to do ''Doctor Who'' novellas, featuring all the Doctors. These eventually spawned another SpinOff, ''Literature/TimeHunter''.
* ''Literature/NewSeriesAdventures'': 2005 onwards. These feature the current TV Doctor and aim themselves towards a more general and kid-inclusive audience. However, the writers like to sneak in references to DarkerAndEdgier works from the ''Doctor Who Expanded Universe''. These new books appear to be in continuity with the TV series, being referenced (in "[[Recap/DoctorWhoNSS1E11BoomTown Boom Town]]" and "[[Recap/DoctorWhoNSS4E17E18TheEndOfTime The End of Time]]" Part One) in the TV show itself.
* ''{{Torchwood}}'' novels: Many of which were also adapted into audio books, which in turn spawned more novels, etc. See TheOtherWiki for [[http://en.wikipedia.org/wiki/List_of_Torchwood_novels_and_audio_books a full list]].
* ''Franchise/IrisWildthyme'': Rogue (alleged) Time Lady, voiced by Katy Manning in the audios (who also played the Third Doctor's companion Jo Grant in the classic series), whose (alleged) TARDIS looks like a red double-decker London bus, smaller on the inside. She actually originated outside the {{Whoniverse}} in a few [[MagicalRealism Magical Realist]] novels by Paul Magrs and got {{transplant}}ed into it. If you're looking for a Whovian equivalent of SquirrelGirl, here she is.
* Puffin ebooks: A monthly series of short ebooks released for the 50th anniversary, featuring the first eleven Doctors in chronological order, written by famous children's authors. Collected as "Literature/DoctorWho11Doctors11Stories". Notably the Ninth Doctor story ''The Beast of Babylon'' gave room for Ninth Doctor adventures without Rose while still allowing the events of "[[Recap/DoctorWhoNSS1E1Rose Rose]]" to be his first adventure.
* ''Time Trips'': BBC Books' analogue to the Puffin ebooks. A monthly series of short ebooks, featuring a different Doctor each story, written by famous novelists. They'd done three ebooks before this, tying in with Series 7 (''The Angel's Kiss'', ''Devil in the Smoke'', and ''Summer Falls'').
* ''Literature/DoctorWhoTalesOfTrenzalore'': This tells the story of some of the Doctor's battles during the Siege of Trenzalore; however, instead of telling it as one big story, ''Tales of Trenzalore'' breaks down the years into four different periods, by four different writers.

[[folder: Audio]]

* ''Doctor Who and the Pescatons'': A 1976 half-drama-half-audiobook on vinyl LP, in which the Fourth Doctor and Sarah fight off an invasion of Earth by the [[FishPeople fish-like]] Pescatons. Also got a Target novelisation, in the final years of the range when they were casting around for new titles.
* ''Exploration Earth: The Time Machine'': An episode of an educational radio show on earth sciences, in which the Fourth Doctor and Sarah Jane guide pupils on a trip to Earth's early geological history, with occasional interruptions from villain Megron.
* ''Slipback'': A serial featuring the Sixth Doctor and Peri, broadcast during a short-lived children's strand of programming on Radio 4. Created to ensure that some kind of ''Doctor Who'' would exist in broadcast media during the gap created by the cancellation of the original Season 23. Like "The Pescatons", also received a Target novelisation.
* ''Radio/ThirdDoctorRadioDramas'': "The Paradise of Death" (for Radio 5) and "The Ghosts of N-Space" (for Radio 2).
* ''Audio Adventures in Time & Space'': A semi-official FanWork production label by BBV (headed by Bill Baggs and Creator/NicholasBriggs). Works from various continuities were produced under the label. Since BBV didn't have the rights to the Doctor, there was a lot of WritingAroundTrademarks involved: for example, Ace would travel with Creator/SylvesterMcCoy as "The Professor", instead of as the Doctor. Some stories focused instead on classic villains, such as the Rani or the Cybermen -- the TV series writers were occasionally involved in writing these audios. Others were based on Creator/NicholasBriggs' Who-clone series ''The Stranger'' (in which Creator/ColinBaker played the titular Sixth Doctor {{Expy}}, and Nicola Bryant was Peri {{Expy}} "Miss Brown").
* ''DoctorWhoAudioVisuals'': A not-at-all official FanWork series created by Creator/NicholasBriggs, starring Creator/NicholasBriggs as the Doctor. Written, composed and produced by Creator/NicholasBriggs. Technically violated BBC copyright, but the BBC choose to look the other way. The series went on for four seasons. It deserves a mention on this list because many of its elements (including its Doctor) later became AscendedFanon both in the ''Magazine/DoctorWhoMagazine'' comics and in Creator/BigFinish.
* AudioPlay/BigFinishDoctorWho: Creator/BigFinish audios, from 1999 onwards, starring classic Doctors and companions. Headed by Creator/NicholasBriggs. Broadly considered canon both by the BBC and by the TV series (officially as of "The Night Of The Doctor"), but comprising many mutually exclusive timelines and continuities, and canonically incompatible with many new TV series events. [[ExiledFromContinuity Big Finish can't legally use elements from or mention events in the 2005 revival series]] because of BBC Audio (with some exceptions, co-produced by BBC Audio), though the occasional sneaky reference snuck its way through. Aside from its main ranges starring the Doctor, the ''Big Finish Doctor Who'' continuity currently includes ([[ArchivePanic but is not limited to]]):

* BBC Audio (aka [=AudioGO=]): Original audio books, as well as recordings of existing novels, featuring TV Doctors and companions. They also recruited Fourth Doctor Creator/TomBaker to do several series of audio plays for them. (To make things ''not confusing at all'', these are now also sold on the Creator/BigFinish website, but are in no way part of the Creator/BigFinish canon.)
** One cooperation project by [=AudioGO=] and Creator/BigFinish, the 50th anniversary "Destiny Of The Doctor" series, enabled Creator/BigFinish to briefly escape the trademark issues around the Ninth, Tenth and Eleventh Doctors.
* ''Kaldor City'': Stories set in the decadent far-future human (probably) culture seen in the Fourth Doctor serial "[[Recap/DoctorWhoS14E5TheRobotsOfDeath The Robots of Death]]". Either an IntercontinuityCrossover or proof that ''Doctor Who'' and ''Series/BlakesSeven'' [[CanonWelding take place in the same universe]]. An earlier Literature/PastDoctorAdventures novel, ''Corpse Marker'', by former ''Who'' writer and ''Blake's Seven'' script editor Chris Boucher, had already crossed this over. In fact, these act as loose sequels to that novel. These have more grounding in the Whoniverse than the ''B7'' universe, though, and featured the surprise return of an old baddy.

** ''Radio/TorchwoodTheLostFiles'' has its own tropes page.

[[folder:Stage Plays]]
!Stage Plays
* ''Theatre/TheCurseOfTheDaleks'', a 1964 stage play serving as an {{Interquel}} between the first Dalek story, "The Daleks", and their second, "The Dalek Invasion of Earth". (The earlier ''The Dalek Chronicles'' comics had done the same.) It did not feature the Doctor or any of his companions.
* ''Theatre/DoctorWhoAndTheDaleksInTheSevenKeysToDoomsday'', a 1974 stage play with a long title, an alternate Fourth Doctor portayed by Trevor Martin (the real Fourth Doctor had yet to appear on television) and also Daleks. And, as you would expect, the Seven Keys to Doomsday.
* ''Recall UNIT: The Great T-Bag Mystery'', a 1984 stage play featuring Mike Yates, John Benton and a single Dalek, but not the Doctor or any of his companions. It was written by Yates' actor Richard Franklin and performed during that year's edition of the Edinburgh Festival Fringe. And no, it has nothing to do with ''{{T-Bag}}''.
* ''[[Recap/BigFinishDoctorWhoTheUltimateAdventure Doctor Who: The Ultimate Adventure]]'', a musical! With singing! And Daleks and Cybermen teaming up! And real Doctors! And MargaretThatcher! (Or at least an actress playing her.) It was performed in 1989. The Daleks and Cybermen did not team up with Margaret Thatcher. EvenEvilHasStandards. Adapted almost word for word as an AudioPlay by Creator/BigFinish, which also convinced playwright Terrance Dicks to give it an audio sequel ("Beyond The Ultimate Adventure").
* ''[[Theatre/DoctorWhoLive Doctor Who Live: The Monsters Are Coming!]]'', a 2010 stage play serving as a sequel to the Third Doctor story "[[Recap/DoctorWhoS10E2CarnivalOfMonsters Carnival of Monsters]]", featuring the son of Vorg from that story and, as you can infer, lots of monsters live on the stage. It did feature the real Doctor... in the form of prerecorded Creator/MattSmith footage which the characters on stage interacted with.
* ''The Crash of the Elysium'', a 2011-2012 interactive stage play produced by immersive theatre codifiers Punchdrunk from an idea by Steven Moffat. It featured the Weeping Angels, more prerecorded Matt Smith footage ([[http://www.bbc.co.uk/news/entertainment-arts-14172300 except for one day]] where Smith appeared in the flesh) and (of course) the crash of a spaceship known as the Elysium. Being a Punchdrunk production, the fourth wall was smashed into bits in this play as the audience was recruited by the military on a quest to face the Angels and rescue the TARDIS, whom they have separated the Doctor from ([[Recap/DoctorWhoNSS3E10Blink again]]).

* ''TabletopGame/TheDoctorWhoRoleplayingGame'': Made by FASA in the 90s. Marred by poor research, which unintentionally generated {{Fanon}}. FASA put out several supplements, along with two choose-your-own-adventure books. Virgin Publishing (the publishers of the New and Missing Adventures lines of novels) did a second RPG in the 90s, called ''TabletopGame/TimeLord''. A third game from Cubicle 7, ''Doctor Who: Adventures in Time and Space'', came out in winter 2009.

!!Tropes used in the games:
* [[BlackKnight Black Cyberknights]]: Show up in one of the pre-generated adventure paths in the RPG. They stage a duel to try to figure out which of the local knights would be best for conversion.
* CursedWithAwesome: Due to [[spoiler: the destruction of the human race]] in 1963 in ''City of the Daleks'', Amy is slowly fading from existence. While this is certainly a bad thing, it also affords her occasional invisiblity, which can come in quite handy during stealth sequences.
* ExpositionFairy: Amy falls into this role for much of ''City of the Daleks.''
* GottaCatchEmAll: ''The Adventure Games'' features a card collecting sidequest, in which you find and collect various cards featuring the Doctor's allies, his enemies, [[TheNthDoctor incarnations of the Doctor himself]], and [[ArsonMurderAndJaywalking different flavours of Jellybabies]].
* LicensedGame:
** The "adventure games" which are tied to series 5 and 6.
** Previously there was ''Destiny of the Doctors'' in the late 1990s and a couple of simple games for the BBC Micro and ZX Spectrum.
* PowerOfLove: Allows Sir Tristan to resist the conversion of the Cybermen because it would take him away from his beloved queen.
* ShoutOut: In one of the ''Adventures In Time and Space'' supplemental adventures, "Knight of the Comet", the only man with a sophisticated enough lab to analyze the wounds left by the Cyberknights is named [[{{Series/Merlin}} Gaius, who is a cantankerous old man and has a well stocked medicine cabinet.]]
* TemporalParadox: Lady Morgana manipulates the players into making one to fuel her Paradox Battery.
* TheTourney: Much less fun if you are thrown through a temporal vortex directly into the middle of one, as happens to the players in "Knight of the Comet"

!!Tropes that appear in the Doctor Who Expanded Universe in general:
* AliensAndMonsters: Depending on the medium, these can get ''very'' outlandish, and often a lot more alien than the TV series (specifically, its budget) would allow for.
* AnyoneCanDie: The ''Magazine/DoctorWhoMagazine'' comics famously killed off [[spoiler:Ace]], Creator/BigFinish sees [[spoiler:Tegan]] dying of cancer, and ''Death Comes To Time'' even permanently killed the Doctor himself. Various works tend to throw in cheeky references to the fact that certain companions are dead in other continuities.
* ArcWelding: Often necessary, but just as often ignored in favour of an AlternateContinuity explanation.
* AscendedFanon: Much of the very unofficial DoctorWhoAudioVisuals ended up re-imagined in AudioPlay/BigFinishDoctorWho and the ''Doctor Who Magazine'' comics, which in turn ended up inspiring official work. This is also generally true for other FanWork contributions by Creator/NicholasBriggs.
* BreakingTheFourthWall: Or in this case, literally shattering it. One DWM comic called "TV ACTION!" (as a nod to the earlier strip title) has the Eighth Doctor and companion Izzy following a villain "into our world", ending up in the BBC studios. Where Tom Baker himself distracts the villain allowing the heroes to save the day.
** A similar story is done in IDW comic "The Girl Who Loved Doctor Who", where the Eleventh Doctor ends up in the real world and even meets Matt Smith.
* TheBusCameBack: Every single ''Series/DoctorWho'' character comes back in the ExpandedUniverse -- and in Creator/BigFinish, they're even usually played by their original actors.
* CanonForeigner: Most works feature at least one original companion, and they tend to stick around for a very long time and appear in other media as well. For example, ''Magazine/DoctorWhoMagazine'' comics companion Frobisher showed up in Creator/BigFinish as well, and eventually in IDW comics. ''Literature/DoctorWhoNewAdventures'' companion BerniceSummerfield has appeared in more novels and audios than can be sensibly listed anywhere. Creator/BigFinish companion Dr. Evelyn Smythe has even appeared in the official BBC web animation "[[Recap/BigFinishDoctorWhoSpecialsRealTime Real Time]]". During 2009, when the Doctor was companion-less on TV, ''DWA'' gave him Heather [=McCrimmon=], a descendent of Jamie. And so on.
* CanonImmigrant: Occasionally, characters from the ''Doctor Who'' Expanded Universe make it into the TV series. Examples are Kate Stewart (from ''Downtime'') and the cast of "Human Nature".
* CastFullOfGay: The majority of the more mature ''Series/DoctorWho'' spinoffs have a lot of gay and bisexual characters, always shown in a very positive way.
* CharacterDevelopment: The classic characters of ''Series/DoctorWho'' all get plenty of development throughout the ExpandedUniverse. The crowning example of this trope is generally considered to be "[[Recap/BigFinishDoctorWhoCCS5E7PeriAndThePisconParadox Peri And The Piscon Paradox]]", written by actress Nicola Bryant's partner Nev Fountain.
* ContinuitySnarl: Different branches and franchises freely reference each other or contradict each other, and no single author has the power to say whether or not something is canon to something else. It's all a bit like a big tangled ball of multicoloured yarn.
* DarkerAndEdgier: Many of the spinoffs, notably the ''Literature/DoctorWhoNewAdventures'' and Creator/BigFinish.
* FantasyKitchenSink: You name it, it's in there. Franchise/IrisWildthyme especially goes all out on this trope.
* FixFic: Many of the less popular aspects of the TV series are explained and "fixed" in the ExpandedUniverse.
* OurVampiresAreDifferent: Ever since the TV series introduced the idea that vampires are very real in ''Series/DoctorWho'', the ExpandedUniverse has been running ''wild'' with different variations on them. Particularly, the ''Literature/EighthDoctorAdventures'', the Creator/BigFinish story arc involving the Forge, the Creator/BigFinish arc involving Rassilon and the Creator/BigFinish ''Jago & Litefoot'' series involve a lot of the blood suckers.
* PromotedFanboy: Almost everyone who started out writing for the Expanded Universe ended up involved in the TV series proper, or in various ''other'' branches of the ''Doctor Who'' Expanded Universe.
* TimeyWimeyBall: Even within a single franchise, the rules of time and space get bent a lot. Between franchises, there are about a hundred different ways time travel can work.
* TropeCodifier:
** Stories by Alan Barnes (in the ''Magazine/DoctorWhoMagazine'' comics and in Creator/BigFinish) codified the "TARDIS as a humanoid woman" trope.
** Jonathan Morris codified the massive TemporalParadox stories that would become regular features of ''Series/DoctorWho'' under Creator/StevenMoffat. Morris' first novel (''Festival of Death'') is seen as the UrExample.
