Cultural references to the Doctor Who universe

Occasionally, elements of the Doctor Who universe are referenced in the broader popular culture. This page exists to throw a spotlight on some of these casual references made in television, comics, films and other media.

Such references generally take two forms: in-universe references which function as brief, unlicensed crossovers where elements of the DWU (or close analogues thereof) are shown to be real within the fictional universe of the work at hand; and out-of-universe references where Doctor Who media, or comedic analogues thereof, are mentioned as media enjoyed by the fictional characters.
