Marvel UK was an imprint of Marvel Comics from the 1970s to the 1990s. The imprint was based in Britain, although many of their comics were produced for the US market.

The imprint is best remembered for creating Captain Britain. Other characters included Death's Head, Motormouth & Killpower and the Knights of Pendragon. In addition, the company published reprints of US Marvel comics. Reprint titles published as anthologies of US stories included Mighty World of Marvel, The Incredible Hulk Presents and Marvel Bumper Comics. They also published reprints of Spider-Man and X-Men comics under a variety of titles. The company also published comics based on licenced characters, most notably Doctor Who Magazine and Transformers, which both featured original material.

In the 1990s Marvel UK made a push to capture a segment of the US comic market. Under editor Paul Neary, the company launched a set of comics set in the Marvel Universe but with more of a focus on Science Fiction and magic rather than Marvel's usual superhero fare. Titles such as Warheads (wormhole hopping mercenaries), Death's Head II (a recreation of Simon Furman's cyborg bounty hunter) and Motormouth & Killpower (streetwise girl and escaped genetically-modified super assassin hop around the universe having adventures) were all linked by plots featuring the organisation Mys-Tech, a shadowy group of Faustians bent on world domination. Some of these titles were also reprinted in a monthly UK anthology Overkill. In the US, these comics were initially immensely successful but after a while too many titles were launched, quality declined and sales dropped. This drop in sales was exacerbated by the 90s comics slump and after only two years Marvel UK ceased its US operations.

Marvel UK is now part of Panini Publishing, which continues to provide reprint titles and DWM.
