Brit-Cit is a huge fictional city in the fictional universe of British comics 2000 AD and Judge Dredd. It is also the home of Sam Slade in some of 2000AD's Robo-Hunter stories. The city covers the south of England and bordering on the Black Atlantic. It also has jurisdiction over Cal-Hab (covering part of Scotland) and Murphyville (Ireland), as seen in the Cal-Hab Justice strip. It is unknown what happened to Wales, outside of a mention of "the Gaels to the West" as a faction in the Brit-Cit Civil War during 2080.
In the first mention of Britain in Judge Dredd, set in 2100, the nation was referred to as the Brit-Territories.
