"The Time of the Doctor" is an episode of the British science fiction television programme Doctor Who, written by Steven Moffat and directed by Jamie Payne, and was broadcast as the ninth Doctor Who Christmas special on 25 December 2013 on BBC One. It is Matt Smith's fourth Christmas special and his final regular appearance as the Eleventh Doctor and the first full appearance of Peter Capaldi as the Twelfth Doctor following his brief cameo in the previous episode "The Day of the Doctor".

The episode also features Jenna Coleman as the Doctor's companion Clara Oswald, plus several enemies of the Doctor, including the Daleks, Cybermen, Silence and Weeping Angels. The episode addresses numerous plot threads developed over the course of Smith's tenure, while also dealing with the regeneration limit established in the 1976 serial The Deadly Assassin.

"The Time of the Doctor" was the most-watched episode of the show in the United States, and obtained a 30.7% viewer share in the UK. It received positive reviews from critics, many of whom called the episode "great". Smith was particularly lauded, and his exit was characterised as graceful and beautiful.
