List of Arab Union cities by population

This is a list of cities by population in the Union of Arab Republics (UAR; informally the Arab Union). According to the All-Union Central Bureau of Statistics, a "city" is defined as any contiguous urban area with a population of at least 10,000; the following list uses this criteria, and as such settlements with less than 10,000 people are not included. It is also important to note that, due to the nature of local government in the Arab Union, cities are geographic/economic entities and not coterminous with legal local government areas, called "councils"; for example, several small cities and their surrounding rural area may be part of a single council, whereas larger cities are often part of more than one council area.
