2000 AD is a weekly British science fiction-oriented comic. As a comics anthology it serialises a number of separate stories each issue (known as "progs") and was first published by IPC Magazines in 1977, the first issue dated 26 February. IPC then shifted the title to its Fleetway comics subsidiary which was sold to Robert Maxwell in 1987 then Egmont UK in 1991. Fleetway continued to produce the title until 2000, when it was bought by Rebellion Developments.

It is most noted for its Judge Dredd stories, and has been contributed to by a number of artists and writers who became renowned in the field internationally, such as Alan Moore, Neil Gaiman, Grant Morrison, Bryan Talbot, Brian Bolland and Mike McMahon.

2000 AD has been a successful launchpad for getting United Kingdom talent into the larger American comics market, and has also been the source of a number of film licences. Unlike earlier weekly titles, 2000 AD was based on a 6 page strip format. This gave the writers greater opportunity to develop character and meant that the artists had greater scope in designing the layout.
