Thirteenth Doctor
fictional character from Doctor Who
The Thirteenth Doctor is an incarnation of the Doctor, the protagonist of the BBC's science fiction television series Doctor Who. She is played by Jodie Whittaker, the first woman to portray the character, in three series, five specials and a cameo in the fifteenth series. As with previous incarnations of the Doctor, the character has also appeared in other Doctor Who spin-offs, both during and after the character's televised appearances.
Within the series's narrative, the Doctor is a millennia-old, alien Time Lord from the planet Gallifrey, with somewhat unknown origins, who travels in time and space in their TARDIS, frequently with companions. At the end of life, the Doctor regenerates; as a result, the physical appearance and personality of the Doctor change. Whittaker's incarnation is a light-hearted adventurer with a passion for building things, placing a high value on friendships and striving for non-violent solutions. Preceded in regeneration by the Twelfth Doctor (Peter Capaldi), she is followed by the Fourteenth Doctor (David Tennant).
This incarnation's first companions were a trio consisting of retired bus driver Graham O'Brien (Bradley Walsh), his dyspraxic step-grandson and part-time warehouse worker Ryan Sinclair (Tosin Cole), and probationary police officer Yasmin "Yaz" Khan (Mandip Gill), all of whom she met shortly after her regeneration. After Graham and Ryan leave, the Doctor and Yaz are joined by food bank volunteer Dan Lewis (John Bishop). She also had one-episode reunions with former companions Captain Jack Harkness (John Barrowman), Tegan Jovanka (Janet Fielding), and Ace (Sophie Aldred).

Why this record matters
The phrase “fictional character from Doctor Who” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 4, 2026. The linked authority identifier is Q33085422. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
