** Back up North, the manufacturing region known as the Rust Belt connects [=BosWash=] with [=ChiPitts=], the city spanning the lower rim of the Great Lakes and beyond. There's still quite a lot of farmland between Chicago and Pittsburgh, but continuous or near-continuous belts of development can be seen from Chicago into northwest Indiana, from Detroit to Toledo (the one in Ohio, not Spain), and from there Cleveland and eastern Ohio kind of gradually spill out into western Pennsylvania (all industrial, but with farms occasionally getting in the way).
*** On the other hand, the metro areas of Chicago and Milwaukee have sprawled to the point that their suburbs now overlap near the Wisconsin-Illinois border (Kenosha, Wisconsin; for example, is considered a suburb of both cities). That's well over 100 miles of urbanized (and suburbanized) land area.
** Back in the South, most of the Florida Peninsula is a single urban area, minus the swamps and theme-parks (which might still count, actually), and the Gulf Coast is a continuous strip of development ranging from Houston, Texas, to at least Pensacola, Florida. Once this one spreads north, the entire US east of the Mississippi and quite a bit west of it will be connected to this one city.
** The West Coast has another smaller one that connects to the Mexican one as well as southwestern Canada, but to a lesser degree in the northern part of it - it's a few hours' drove between the main cities of the Northwest, most of which is forests or fields.

* ''GunnerkriggCourt'': The court itself has gigantic proportions, its full size has yet to be revealed.

** Beyond the Imperial Palace, Earth (or "''Holy Terra''" as it is officially designated) has been depicted in more recent iterations as a CityPlanet, and described as one of the larger Hive Worlds in the Imperium. However, it lacks many of the common fictional features of [[{{MegaCity}} Mega Cities]] and {{CityPlanet}}s in that it's not really a trading hub, but rather the holiest of holy religious sanctuaries, and the entire planetary surface amounts to a massive, militarised religious compound in which the most trusted servants of the GodEmperor are allowed to live.

* ''{{Warhammer 40000}}'': The Imperial Palace covers all of Eurasia. (The Golden Throne and Astronomicon, counting attendant machinery and security, consumes [[RefugeInAudacity Mount Everest's entire interior volume]] all on its own.) Though what modern continents match up to what building (yes, building) sometimes varies.
** Also, Imperial hive cities.

* Cairo and Lagos in Africa

* ''TheThirteenAndAHalfLivesOfCaptainBluebear'': The Capital of the continent of Zamonia, Atlantis, has over 200 million inhabitants.

* {{Discworld}}: While Ankh-Morpork only has a million inhabitants, it is still the biggest city in the [[MedievalStasis setting]]. In ''Discworld/TheFifthElephant'', Carrot points out that it's actually the largest dwarf city, having more dwarfs than any purely dwarf city.

This will probably be the CapitalCity, and if it's not a MerchantCity, there'll definitely be a BazaarOfTheBizarre if you know where to look. Occasionally, a MegaCity will be so large it is effectively a CityPlanet.

** Back in the South, most of the Florida Peninsula is a single urban area, minus the swamps and theme-parks (which might still count, actually), and the Gulf Coast is a continuous strip of development ranging from Houston, Texas, to at least Pensacola, Florida, where this troper lives, and he can tell you that there's less than an hour's drive East before you hit another strip that goes from the tiny town of Navarre, through Destin, Panama City, and Tallahassee, and possibly beyond. Once this one spreads north, the entire US east of the Mississippi and quite a bit west of it will be connected to this one city.

** Dredd's home city of Mega City One grew from BosWash (See Real Life examples below) until it covered the entire eastern seaboard. In fact, the whole point of the ''Apocalypse War'' arc was to trim its sheer size down, as it had become too big.

** The first was known originally as BosWash, a contiguous mass of cities and suburbs running from Boston to Washington DC. This has now expanded to include cities further north, and it's soon to connect to the rim of cities around the Chesapeake Bay, and thence to Piedmont, the mega-metropolis that runs from Charlotte, North Carolina, to Atlanta, Georgia, to Nashville, Tennessee (and possibly Memphis).

* The city of Ravnica from ''MagicTheGathering''. It's a city that covers a whole '''DIMENSION''', forget about a continent!

* Mort City in ''SLAIndustries''.
