List of Doctor Who Christmas and New Year's specials

Doctor Who is a British science fiction television programme produced by the British Broadcasting Corporation (BBC). The show has had a large influence in the media and across society since its inception in 1963. Beginning in 2005, yearly special Christmas episodes were produced in addition to a regular series until 2017. From 2018–2022 (with the exception of 2020) the show temporarily transitioned to New Year's Day specials instead. Beginning in 2023, the programme returned to producing Christmas specials. From 1963–1989 episodes were occasionally broadcast on holidays but often had little mention of the occurrence.

The holiday episodes have proven to be a success with viewers, by bringing in larger viewing figures than regular episodes of the programme. The 2008 special, "Voyage of the Damned" is the most-viewed Doctor Who episode since 2005 and held a record for the highest watched BBC drama from its broadcast until 2021. "A Christmas Carol" is often considered by critics to be the best Christmas episode.

In 2015, a DVD and Blu-ray boxset was release containing 10 of the Christmas specials. Doctor Who, along with other television series in the Whoniverse, have occasionally broadcast episodes on other holidays.

Doctor Who revolves around an alien Time Lord called the Doctor who travels with a companion in a time and space machine called the TARDIS. Instead of dying, the Doctor regenerates by changing every cell in their body and taking on a new appearance. Throughout their adventures the Doctor and their companion frequently stop other aliens from committing acts of violence.
