This is a list of Doctor Who television writers. It is sortable by a number of different criteria.[1] The list defaults to ascending alphabetical order by the writer's last name.

A note to editors: Before changing anything about this list, please make sure that you have thoroughly read and understood all footnotes. Of necessity, this list has several assumptions which may or may not coincide with your personal interpretation of Doctor Who history.

Several assumptions underlie the composition of the list. Most significantly, this list defines a "writer of Doctor Who" to be a person who received onscreen credit for a live-action, non-parodic story. That Terrance Dicks in fact wrote four of the six episodes of The Seeds of Death is irrelevant to this list; Brian Hayles is the only person whose name appears on screen so he's the only one who gets credit here. Where possible and necessary, notes have been included to shed light on what a particular writer actually did as opposed to what they were credited for. However, the best source of information about the writing of particular stories is more likely to be the story page itself.

Further details about the way in which this list was compiled can be found by clicking the footnote marker at the top of each column. Information on this list is current through The Day of the Doctor.

"David Agnew"2The Invasion of TimeCity of Death10250"David Agnew" was a pseudonym used on several BBC programmes in the 1970s. On Doctor Who it was used exclusively by Graham Williams and his script editors, apparently under the direct orders of the then-BBC Head of Serials.[8]On The Invasion of Time, it concealed the identities of Williams and Anthony Read, while on City of Death, it masked the involvement of Williams, Douglas Adams and David Fisher.&1000000000000004000000040 years, &10000000000000260000000260 days

Anthony Coburn 1 An Unearthly Child An Unearthly Child 4 100 Ironically, the first writer for Doctor Who wasn't British, but Australian. Although contemporary BBC internal documents reveal that C. E. Webber was really his co-author for the first episode,[10] only Coburn's name made it to the screen. Coburn, however, is more or less completely responsible for the 2nd-4th episodes that comprise the bulk of the story, as his original brief was to write one of the middle serials of the first season. When his script was suddenly moved to the start of the season, his original first part was mostly replaced by C. E. Webber's script for the pilot episode.[11] &1000000000000005400000054 years, &10000000000000333000000333 days

Russell T Davies 25 Rose The End of Time 32 1593[12] Davies is the original head writer and producer of the BBC Wales version of Doctor Who. He has also written far more stories than anyone else in Doctor Who history, although Robert Holmes holds a comfortable lead in terms of number of episodes. Davies has the further distinction of receiving onscreen credit for writing the first episodes of Doctor Who (2005), Torchwood and The Sarah Jane Adventures. Planet of the Dead was co-written with Gareth Roberts, the first occasion on which two writers have been credited for a single script since the programme returned in 2005. &1000000000000001300000013 years, &10000000000000210000000210 days
Gerry Davis 4 The Tenth Planet Revenge of the Cybermen 12 300Davis was the only script editor of the 1963 series to receive credit on the last episode of one Doctor and the first episode of another.

Terrance Dicks 5 The War Games The Five Doctors 23 750He received onscreen credit for co-wiring The War Games with Malcolm Hulke. However, as the longest-serving script editor, Dicks had many uncredited contributions to scripts. One of the most glaring examples of this was The Seeds of Death, whose final four episodes are mostly Dicks' own work, but for which only Hayles retains credit. Though he does have a writing credit in the Troughton era, and he is indelibly linked to the Pertwee era, the bulk of his writing credits are actually for the Fourth Doctor. Ironically, while writing for script editor Robert Holmes, he got a taste of what it was like to be on the other end of a script editor's rewrites, and chose to take his name off of The Brain of Morbius"'. &1000000000000004900000049 years, &10000000000000186000000186 days

Robert Holmes 15.5 The Krotons The Ultimate Foe 64 1660 Bob Holmes was the most prolific writer of the classic era. Until the BBC Wales version, no one had written more stories. As of 2017, his episode record remains daunting, even to Russell T Davies and Steven Moffat, the only writers with a chance to beat him. Holmes rewrote The Ark in Space, for which its original writer, John Lucarotti, was fully paid. He also based his version of The Talons of Weng-Chiang another script for which the original writer, Robert Banks Stewart, was fully paid. Neither Lucarotti nor Banks, however, received on screen credit for their efforts. &1000000000000004900000049 years, &10000000000000298000000298 days

He also co-wrote, but was not credited for, The Ambassadors of Death.[15] His somewhat surprisingly large run time derives from the fact his stories averaged 6.71 episodes.&1000000000000005100000051 years, &10000000000000197000000197 days

Eric Saward 4 The Visitation Revelation of the Daleks 12 380Saward's name appears on the credits of only four stories. Two of these stories, Revelation and Resurrection of the Daleks were originally broadcast as two, 45-minute episodes. This means he received on-screen writer's credit on twelve episodes. Nevertheless, strong evidence exists that he wrote, but did not receive credit for, Attack of the Cybermen.[20] Most recently on the DVD release of Trial of a Time Lord, he also claims to have mostly written part 13 of that story, as well as several courtroom scenes for all four serials in the arc.&1000000000000003600000036 years, &10000000000000249000000249 days

Dennis Spooner 3.5 The Reign of Terror The Daleks' Master Plan 20 500Spooner was the programme's second script editor.

David Whitaker 8 The Edge of Destruction The Ambassadors of Death 40 950 Whitaker was the programme's first script/story editor. Aside from the authors of The Three Doctors and The Five Doctors, he is the only person to be credited with writing at least one story featuring each of the first three Doctors. The writing of his final adventure, The Ambassadors of Death, was particularly precarious. Both Malcolm Hulke and Trevor Ray were required, uncredited, to get a final set of scripts completed.[15] &1000000000000005400000054 years, &10000000000000256000000256 days

Notes Edit

  1. On mobile Wikia, sorting functionality is disabled.
  2. A "writer" is defined by this list as the person or persons who received onscreen credit for writing the script. Note that this can include pseudonyms but exclude the actual person or persons known to be indicated by the pseudonym. Pseudonyms are indicated by the use of question marks around the name. This column sorts by the last name of the individual. It does not include such credits as: "based on an idea by", "story by", and other such creative credits that fall short of a scriptwriting credit.
  3. A "story" is a grouping of one of more episodes that form a single narrative. It is not to be confused with a story arc. In the 1963 version of the programme, a "story" was a single serial, which might have comprised anywhere from one to twelve episodes, although the most common number was four. Since the 1996 telemovie, most stories have been a single episode in length. Where multi-part stories have been produced by the BBC, the titles to both parts are given so as to indicate the entirety of the story. Episodes of unusually short duration produced by BBC Wales, such as Time Crash, are considered to be single stories, for the purpose of this column. Writers may be credited with a fraction of a story if their name appears on only some of the episodes within a single story.
  4. 4.0 4.1 This column sorted by the first word in the title which is not an article.
  5. An episode is considered to have whatever length it had on first broadcast on BBC One. For the purposes of this column, certain stories, like Resurrection of the Daleks and The Five Doctors have two parts and one part, respectively — even though these stories are often presented as four-parters. The following things are deemed to be single episodes: the 1996 telemovie, the Children in Need Special, Time Crash, Music of the Spheres, and any other future non-parodic live-action "mini-episodes" produced by BBC Wales. Time and Space are considered one story. Prequels and the exclusive-to-home-video sketches included with the series 5 and series 6 box sets are considered part of other stories within those series, and are therefore not counted separately. Animated episodes are specifically excluded from this list, as is Dimensions in Time.
  6. "Run time" refers to the total amount, in minutes, of Doctor Who material contributed by the writer in question. Due to the differing format of episodes through the years, run time gives a better basis of comparison between writers than episode count. The math used for this column assumes a 25-minute run time for most episodes of "old Who" and 45 minutes for each episode of "new Who". Exceptions, such as the episodes of Colin Baker's first full season, part 14 of The Trial of a Time Lord and Journey's End shall be factored in based on their actual run time. As in the rest of the table, the format seen in the original broadcast on BBC One shall take precedence over later formats of the same story.
  7. "Since first episode" calculates the amount of elapsed time between today and the date of the original broadcast of the first episode for which a writer received on-screen credit. This is not the same as when their involvement with the programme may have begun — a figure that would be much more speculative. Nevertheless, it is a useful tool for broadly sorting the writers chronologically, especially for those users not intimately familiar with Doctor Who history.
