Antwerp (English: /ˈæntwɜrp/ ( listen); Dutch: Antwerpen, [ˈɑnt.wɛr.pə(n)] ( listen); French: Anvers, [ɑ̃vɛʁ] or [ɑ̃vɛʁs]); Latin: Amberes [ˈɑm.bɛ.rɛs], is a city and municipality in Belgium and the capital of the Antwerp province of Flanders. Antwerp's total population is 507,007 (as of 31 December 2011), making it the largest municipality in both Flanders and Belgium in terms of its population. Its total area is 204.51 km² (78.96 sq mi), giving a population density of 2,308 inhabitants per km². The metropolitan area, including the outer commuter zone, covers an area of 1,449 km² (559 sq mi) with a total of 1,190,769 inhabitants as of 1 January 2008. The inhabitants of Antwerp are locally nicknamed Sinjoren, after the Spanish honorific señor. It refers to the leading Spanish noblemen who ruled the city during the 17th century.

Antwerp has long been an important city in the Low Countries both economically and culturally, especially before the Spanish Fury (1576) in the period of the Dutch Revolt. It is located on the right (eastern) bank of the river Scheldt, which is linked to the North Sea by the estuary Westerschelde. The city has one of the largest seaports in Europe.

A city is a relatively large and permanent settlement. Although there is no agreement on how a city is distinguished from a town within general English language meanings, many cities have a particular administrative, legal, or historical status based on local law.

For example, in the U.S. state of Massachusetts an article of incorporation approved by the local state legislature distinguishes a city government from a town. In the United Kingdom and parts of the Commonwealth of Nations, a city is traditionally a settlement with a royal charter. Historically, in Europe, a city was understood to be an urban settlement with a cathedral.

Cities generally have complex systems for sanitation, utilities, land usage, housing, and transportation. The concentration of development greatly facilitates interaction between people and businesses, benefiting both parties in the process. A big city or metropolis usually has associated suburbs and exurbs. Such cities are usually associated with metropolitan areas and urban areas, creating numerous business commuters traveling to urban centers for employment. Once a city expands far enough to reach another city, this region can be deemed a conurbation or megalopolis.
