{{real world}}

A '''crossover''' is a story in which elements from two or more {{w|fictional universe|fictional universes}}, originally created to be distinct, are brought together for the span of a specific narrative.

* The planet [[Kemble]], which appeared in [[Terry Nation]] and [[Dennis Spooner]]'s [[1965 (releases)|1965]] serial ''[[The Daleks' Master Plan (TV story)|The Daleks' Master Plan]]'' and its lead-in ''[[Mission to the Unknown (TV story)|Mission to the Unknown]]'', previously debuted in Spooner's [[1963 (releases)|1963]] ''[[Fireball XL5 (series)|Fireball XL5]]'' episode ''[[w:c:gerryanderson:Space Vacation|Space Vacation]]''.

* In the [[1965 (releases)|1965]] episode "[[The Feast of Steven]]", the ''Doctor Who'' production team planned to use the main cast and setting of ''[[Z-Cars]]'' for some scenes set in a police station. However, ''Z-Cars'' producer {{w|David Rose (producer)|David Rose}} rejected the idea. The plan was referenced in [[The Mutation of Time (novelisation)|the 1989 novelisation]], which named the policemen after the ''Z-Cars'' cast.

* Another early, albeit minor, televised crossover between the DWU and another fictional property occurred in [[1966 (releases)|1966]] in ''[[Thunderbirds (series)|Thunderbirds]]'', on [[ITV]] rather than the [[BBC]], as a tie-in with the magazine ''[[TV Century 21]]'', which published [[The Daleks (series)|the ''Daleks'' comic serials]] under the guise of being in-universe reports produced in the [[2060s]] within the shared universe of [[Gerry Anderson]]'s science fiction TV series. One of these reports was clearly seen, although briefly, on-screen in a close-up in the ''Thunderbirds'' episode ''[[The Man from MI.5 (TV story)|The Man from MI.5]]'', with the word "DALEK", the image of a [[Dalek War Machine|War Machine Dalek]] and that of the [[Dalek Prime|Golden Emperor]] all visible.

* The final episode of Season 3 of ''[[Out of the Unknown (TV series)|Out of the Unknown]]'', entitled ''[[Get Off My Cloud (TV story)|Get Off My Cloud]]'', was an official crossover with ''Doctor Who'' through a metafictional device: the main character became trapped in a dream world where he was menaced by [[Dalek]]s drawn from his nightmares, nightmares developed from watching ''Doctor Who'' itself. He eventually summoned [[the Doctor's TARDIS]] ("played" by the actual TV prop used at the time in [[Patrick Troughton]]'s TV stories) inside the dream realm as part of his efforts to defend himself.

* In [[1991 (releases)|1991]], ''[[The Totally Stonking, Surprisingly Educational And Utterly Mindboggling Comic Relief Comic (comic story)|The Totally Stonking, Surprisingly Educational And Utterly Mindboggling Comic Relief Comic]]'' was released as promotion for the ''[[Comic Relief]]'' charity event, crossing the DWU over with several other series, most notably featuring [[Dan Dare]] (''[[Dan Dare (series)|Dan Dare]]'') encountered the first seven incarnations of [[the Doctor]] and several companions.

* In 2012, [[IDW Publishing|IDW]] published ''[[Assimilation² (comic story)|Star Trek: The Next Generation/Doctor Who: Assimilation²]]'', a crossover between ''Doctor Who'' and ''[[Star Trek: The Next Generation]]''.
