History Main / MegaCity

* Later in the ''Robots/Empire/Foundation'' series, Trantor, and presumably a few other worlds, are globe-spanning versions of these with populations in the billions. Trantor is very much the model for Coruscant.

* The city of Los Angeles, California has become one of these in the aftermath of [[TheEndOfTheWorldAsWeKnowIt the Vanishing]] on ''Fanfic/CoreLine''. The old Los Angeles became an underground city wherein all kind of CyberPunk tropes are done willy-nilly, and it's essentially become the town's Red Light District.

* The City in ''ComicBook/{{Transmetropolitan}}''.

* Although it may not seem like much compared to other entries in this list, UsefulNotes/{{London}} was probably the first modern metropolis with a population of 6.7 million in the 1900s. It is still one and the largest among European cities, with 14 million people living in the [[https://en.m.wikipedia.org/wiki/London_commuter_belt London commuter belt]] which includes the [[https://en.m.wikipedia.org/wiki/Greater_London Greater London]] area.
* Speaking of European cities, UsefulNotes/{{Paris}} and the surrounding [[https://en.m.wikipedia.org/wiki/Île-de-France Île-de-France region]] also counts. 12 million or approximately one fifth of the French population lives in the region, making it the fourth largest metropolitan area within Europe.

** The [[https://en.m.wikipedia.org/wiki/BUG%27s Busan-Ulsan-Gyeongsangnamdo metropolitan area]] isn't as large as the Seoul metropolitan area, but it still houses 8 million people, making it the second largest metropolitan area in South Korea.
* Another East Asian state, the de facto nation UsefulNotes/{{Taiwan}}, also has one, the [[https://en.m.wikipedia.org/wiki/Taipei–Keelung_metropolitan_area Taipei metropolitan area]] with 7 to 9 million people.

* In most series, [[Franchise/{{Transformers}} Cybertron]] is about as large as the Earth, all the way up to the size of ''Saturn'' in some series. Despite this, most of it's cities aren't just ''visible'' from orbit, they're so large they visibly alter the planet's silhouette.

* ''Literature//OnTheEdgeOfEureka'' has Eleutheria, a metropolis so large it covers the planet.

* Mute City in ''VideoGame/{{F-Zero}}''. Formerly called New York City (according to the anime), it grew to a population of over two billion people and aliens.

* The proper term to describe cities -- more specifically, broad-stroke regions -- that have reached extreme levels of population and urban development is ''[[https://en.wikipedia.org/wiki/Megalopolis_(city_type) megalopolis]]''; a [[https://en.wikipedia.org/wiki/Megacity megacity]], on the other hand, is typically defined as "a metropolitan area with a total population in excess of ten million people". While there is considerable overlap between the two terms, a crucial difference is that a megacity can be a single metropolis, while a true megalopolis comprises a '''chain''' of highly interlinked metropolises. The following examples listed below all qualify as megalopolises, as most of them are a chain of metropolitan areas that are so closely connected to each other that they have begun to overlap.

* According to TheOtherWiki, there are about [[http://en.wikipedia.org/wiki/List_of_urban_areas_by_population as many people in Jakarta]] [[http://en.wikipedia.org/wiki/List_of_countries_by_population as there are people in Australia]] (especially if you count Jakarta's satellite cities and zones).

* Speaking of European cities, UsefulNotes/{{Paris}} and the surrounding [[https://en.m.wikipedia.org/wiki/Île-de-France Île-de-France region]] also counts. 12 million or approximately one fifth of the French population lives in the region, making it the second largest metropolitan area within Europe, excluding Moscow.

* Outside of the western world:
** There are very large cities in China such as Shanghai (20 million) and Beijing (17 million) and there are a number of large cities in the Pearl River Delta such as Shenzhen (12 million) and Guangzhou (16 million) [[http://www.telegraph.co.uk/news/worldnews/asia/china/8278315/China-to-create-largest-mega-city-in-the-world-with-42-million-people.html which may one day merge to form the largest mega city in the world]].
*** Foreign media often neglects the differences between a city proper and a [[http://en.wikipedia.org/wiki/Prefecture-level_City City-Prefecture unitary authority]], resulting in plain wrong statements. The prefecture is often much larger and populous than the city proper of the same name, comparable to a small European country.

** Mumbai and Delhi/New Delhi in India have populations of over 20 million and over 15 million respectively.
** UsefulNotes/{{Cairo}} (20 million people when you include Giza and the suburbs, which you should) and Lagos (12 million) in Africa.
* UsefulNotes/{{Seoul}} is also this. In fact, half of the population of UsefulNotes/{{South Korea}} resides in the [[https://en.m.wikipedia.org/wiki/Greater_London Seoul Capital Area]] (25 million) with 10 million of them in Seoul, making it one of the largest metropolitan area in terms of population.

** There's also Cammoragh, the ''city dimension'' of Dark Eldar, which supposedly dwarfs imperial Hive worlds in size. Supposedly, because it's an extra-dimensional conglomerate of megapolicies, arranged in a way that [[AlienGeometry defies all common sense]]. It's also arguably the most evil place in the universe

* The proper term to describe cities -- more specifically, Broad-stroke regions -- that have reached extreme levels of population and urban development is ''Megalopolis''. The following examples listed below all qualify, as most of them are a chain of metropolitan areas that are so closely connected to each other that they have begun to overlap.

* Kaineng City from ''GuildWars Factions''.

** The UsefulNotes/DFWMetroplex Metroplex of Texas has about 6.5 million inhabitants living in well over 200 individual towns and cities, the largest metropolitan area in the Southern United States. It is generally split between two main divisions, the Dallas-Plano-Irving group and the Fort Worth-Arlington group, but they're all close enough that it hardly matters.

** There are very large cities in China such as Shanghai (20 million) and Beijing (17 million) and there are a number of large cities in the Pearl River Delta such as Shenzhen (12 million) and Guangzhou (16 million) which may one day merge to form the largest mega city in the world [[http://www.telegraph.co.uk/news/worldnews/asia/china/8278315/China-to-create-largest-mega-city-in-the-world-with-42-million-people.html]].

*** When Chaohu prefecture (population 4 million) was dissloved, there are news claiming a city as large as Los Angeles suddenly disappeared from map. The Chaohu city proper (not really annexed but now a county-level city belongs to Hefei prefecture) have a population of about 800,000.
*** "World's most populous" Chongqing Municipality is a merger of 4 former prefectures, have a population of 29 million, and larger than Scotland. The real city proper of Chongqiong, have 8 million residents.
*** "World's biggest by land area" Hulunbuir, Inner Mongolia is even larger than the entire UK. This city-prefecture contains several counties and other cities (as the norm), the real city proper (Hailar District) occupies 0.5% of the total land, and not big by Chinese standards.
*** The above figures for Beijing, Shanghai, Guangzhou, Shenzhen is similarly inflated, as a prefecture may have many rural counties. Nonetheless, their urban area is large on their own. If you count people regularly resides (as opposed to only those have Hukou which is official permanent residence and entitles you to full social benefits of such city) then Beijing and Shanghai already have over 20 million people in city proper (as of 2014).
*** Shanghai Metro have crossed Shanghai-Jiangsu province border with stations in Huaqiao, Suzhou Prefecture, Jiangsu (not Suzhou city proper, but easily reached by Suzhou city bus). Downtown Suzhou is 80km away from Downtown Shanghai.
*** After Feb 2014, there does not exist a single county in Southern Jiangsu and one one in Shanghai (the distant Chongming Island). All such areas, home to over 53 million people, are city districts or county-level cities, although many suburbs are not meant to be completely urbanized. This does not even include cities on the north bank of the Yangtze (Central Jiangsu) or further south (Northern Zhejiang) where urban areas are not large enough to touch each other but still heavily connected via numerous expressways (not to mention high-speed rail).
*** Guangzhou have effectively integrated neighboring Foshan (which is 20 km away from downtown Guangzhou, administratively still a separate prefecture-city), and the larger Pearl River Delta, not only Shenzhen, is also urbanized and interconnected similar to above. (Even includes Hong Kong despite border controls, with Shenzhen Metro and Hong Kong MTR connecting at checkpoints)

* Another East Asian state, the de facto nation UsefulNotes/{{Taiwan}} also has one, which is the [[https://en.m.wikipedia.org/wiki/Taipei–Keelung_metropolitan_area Taipei metropolitan area]] with 7 to 9 million people.

* There are about as many people in UsefulNotes/{{Tokyo}} and neighboring cities as there are people in [[CanadaEh Canada]], which makes the TokyoIsTheCenterOfTheUniverse trope feels juuuuust a little bit {{Justified|Trope}}. If Tokyo were a separate country, it would be the 34th most populous in the world, after UsefulNotes/{{Poland}}.

* Keihanshin (Kyoto-Osaka-Kobe) is no slouch either. The figures varies depending on the method, but it is somewhere around 17-20 million people. Unlike other metropolitan regions, however, Keihanshin was unique in that UsefulNotes/{{Kyoto}} and Osaka were (and to some extent, still are) separate cities with separate civic cultures for most of Japan's history. It was only until rise of modern transport in the early-to-mid 20th Century that the two cities started to form an integrated metropolitan region.

* Speaking of European cities, UsefulNotes/{{Paris}} and the surrounding [[https://en.m.wikipedia.org/wiki/Île-de-France Île-de-France region]] also counts. 12 million or approximately one fifth of the French lives in the region, making it the second largest metropolitan area within the European region, excluding Moscow.

Notice that, despite the introduction, a given city does not count as a Mega City just because it is bigger than ''some'' country. For example, in real life a whopping 41 countries around the world have less than a million inhabitants, 17 of those have even less than 100,000, and cities of that size in other countries are normal and therefore would not be seen as mega cities.

** Moscow (12 million officially, over 20 million if you count all them transients, unregistered residents and illegal migrants, and another 5 million from the suburbs).

* Mega-Primus in ''{{X-Com}}: Apocalypse''. According to the {{backstory}}, it's actually the prototype of the concept designed to consolidate the remaining living space on the planet following the aversion of NoEndorHolocaust at the end of ''Terror from the Deep''.

* Speakin of European cities, UsefulNotes/{{Paris}} and the surrounding [[https://en.m.wikipedia.org/wiki/Île-de-France Île-de-France region]] also counts. 12 million or approximately one fifth of the French lives in the region, making it the second largest metropolitan area within the European region, excluding Moscow.

* Seoul is also this. In fact, half of the population of UsefulNotes/{{South Korea}} resides in the Seoul metropolitan area (25 million) with 10 million of them in Seoul, making it one of the largest metropolitan area in terms of population.
** The Busan-Ulsan-Gyeongsangnamdo metropolitan area isn't as large as the Seoul metropolitan area, but it still houses 8 million people, making it the second largest metropolitan area in South Korea.
* Another East Asian state, the de facto nation UsefulNotes/{{Taiwan}} also has one, which is the Taipei metropolitan area with 8 million people.
