List of primate cities: A primate city is a major city that works as the financial, political, and population center of a country and is not rivaled in any of these aspects by any other city in that country.  Normally, a primate city must be at least twice as populous as the second largest city in the country.

Among the best known examples of primate cities are the alpha world cities of London and Paris.  Other major primate cities include Athens, Baghdad, Bangkok, Budapest, Buenos Aires, Cairo, Dublin, Jakarta, Kuala Lumpur, Lima, Mexico City, Moscow, Seoul, Tehran,Tokyo and Vienna.
