Metropolitan regions in Germany in the context of "Hamburg"

The Rhine-Ruhr metropolitan region (German: Metropolregion Rhein-Ruhr) is the largest metropolitan region in Germany, with over ten million inhabitants. A polycentric conurbation with several major urban concentrations, the region covers an area of 7,110 square kilometres (2,750 sq mi), entirely within the federal state of North Rhine-Westphalia. The Rhine-Ruhr metropolitan region spreads from the Ruhr area (Dortmund-Bochum-Essen-Duisburg) in the north to the urban areas of the cities of Mönchengladbach, Düsseldorf (the state capital), Wuppertal, Leverkusen, Cologne (the region's largest and Germany's fourth largest city), and Bonn in the south. The location of the Rhine-Ruhr at the heart of the European Blue Banana makes it well connected to other major European cities and metropolitan areas such as the Randstad, the Flemish Diamond and the Frankfurt Rhine Main Region.

The metropolitan area is named after the Rhine and Ruhr rivers, which are the region's defining geographical features and historically its economic backbone.

The Rhine-Main Metropolitan Region, often simply referred to as Frankfurt Rhine-Main, Frankfurt Rhine-Main area or Rhine-Main area (German: Rhein-Main-Gebiet, Frankfurt/Rhein-Main or FrankfurtRheinMain, abbreviated FRM), is the third-largest metropolitan region in Germany after Rhine-Ruhr and Berlin-Brandenburg, with a total population exceeding 5.9 million. The metropolitan region is located in the central-western part of Germany, and stretches over parts of three German states: Hesse, Rhineland-Palatinate, and Bavaria. The largest cities in the region are Frankfurt am Main, Wiesbaden, Mainz, Darmstadt, Offenbach, Worms, Hanau, and Aschaffenburg.

The polycentric region is named after its core city, Frankfurt, and the two rivers Rhine and Main. The Frankfurt Rhine-Main area is officially designated as a European Metropolitan region by the German Federal Ministry of Transport, Building and Urban Affairs and covers an area of roughly 13,000 square kilometers (5,000 sq mi).

Stuttgart (/ˈstʌtɡɑːrt, ˈstʊt-/; German: [ˈʃtʊtɡaʁt] ; Swabian: Schduagert [ˈʃd̥ua̯ɡ̊ɛʕd̥]; Alemannic: Stuttgart; names in other languages) is the capital and largest city of the German state of Baden-Württemberg. It is located on the Neckar river in a fertile valley known as the Stuttgarter Kessel (Stuttgart Cauldron) and lies an hour from the Swabian Jura and the Black Forest. Stuttgart has a population of 613,111 as of 2023, making it the seventh largest city in Germany, while over 2.8 million people live in the city's administrative region and nearly 5.5 million people in its metropolitan area, making it the fourth largest metropolitan area in Germany. The city and metropolitan area are consistently ranked among the top 5 European metropolitan areas by GDP; Mercer listed Stuttgart as 21st on its 2015 list of cities by quality of living; innovation agency 2thinknow ranked the city 24th globally out of 442 cities in its Innovation Cities Index; and the Globalization and World Cities Research Network ranked the city as a Beta-status global city in their 2020 survey. Stuttgart was one of the host cities for the official tournaments of the 1974 and 2006 FIFA World Cups.

Stuttgart is unusual in the scheme of German cities. It is spread across a variety of hills (some of them covered in vineyards), valleys (especially around the Neckar river and the Stuttgart basin) and parks. The city is known as the "cradle of the automobile". As such, it is home to famous automobile museums like the Mercedes-Benz Museum and Porsche Museum, as well as numerous auto-enthusiast magazines, which contributes to Stuttgart's status as Germany's "Autohauptstadt" ("car capital city"/"capital of cars"). The city's tourism slogan is "Stuttgart offers more". Under current plans to improve transport links to the international infrastructure (as part of the Stuttgart 21 project), Stuttgart unveiled a new city logo and slogan in March 2008, describing itself as "Das neue Herz Europas" ("The new Heart of Europe"). For business, it describes itself as "Where business meets the future". In July 2010, the city unveiled a new logo, designed to entice more business people to stay in the city and enjoy breaks in the area.

The Munich Metropolitan Region is one of eleven metropolitan regions in Germany, consisting of the agglomeration areas of Munich, Augsburg, Ingolstadt, Landshut, Rosenheim and Landsberg am Lech. It is Germany's richest and fifth most populous metropolitan region after the Rhine-Ruhr Metropolitan-Region, the Frankfurt Rhine-Main-Region, the Berlin-Brandenburg Metropolitan-Region and the Stuttgart Metropolitan-Region.

Frankfurt am Main, commonly referred to simply as Frankfurt, is the most populous city in the German state of Hesse. Its 778,589 inhabitants as of 2025 make it the fifth-most populous city in Germany. Located in the foreland of the Taunus on its namesake Main, the city forms a continuous conurbation with Offenbach am Main; its urban area has a population of over 2.7 million. Frankfurt is the heart of the larger Rhine-Main metropolitan region, which has a population of more than 5.8 million and is Germany's second-largest metropolitan region after the Rhine-Ruhr region. Home to the European Central Bank, the city serves as one of the four institutional seats of the European Union (alongside Brussels, Luxembourg and Strasbourg). Frankfurt is classified by the GaWC as an Alpha-rated world city.

Frankfurt was a city state, the Free City of Frankfurt, for nearly five centuries, and was one of the most important cities of the Holy Roman Empire, as a site of Imperial coronations; it lost its sovereignty upon the collapse of the empire in 1806, regained it in 1815 and then lost it again in 1866, when it was annexed (though neutral) by the Kingdom of Prussia. It has been part of the state of Hesse since 1945. Frankfurt is culturally, ethnically and religiously diverse, with half of its population, and a majority of its young people, having a migrant background. A quarter of the population consists of foreign nationals, including many expatriates. In 2015, Frankfurt was home to 1,909 ultra high-net-worth individuals, the sixth-highest number of any city.

The Hamburg Metropolitan Region (German: Metropolregion Hamburg) is a metropolitan region centred around the city of Hamburg in northern Germany, consisting of eight districts (Landkreise) in the federal state of Lower Saxony, six districts (Kreise) in the state of Schleswig-Holstein and two districts in the state of Mecklenburg-Vorpommern along with the city-state of Hamburg itself. It covers an area of roughly 26,000 square kilometres (10,000 sq mi) and is home to more than 5.1 million inhabitants.

Brandenburg, officially the State of Brandenburg (see Names), is a state in northeastern Germany. Brandenburg borders Poland and the states of Berlin, Mecklenburg-Vorpommern, Lower Saxony, Saxony-Anhalt, and Saxony. It is the fifth-largest German state by area and the tenth-most populous, with 2.5 million residents. Potsdam is the state capital and largest city. Other major towns are Cottbus, Brandenburg an der Havel and Frankfurt (Oder).

Brandenburg surrounds the national capital and city-state of Berlin. Together they form the Berlin/Brandenburg Metropolitan Region, the third-largest metropolitan area in Germany. There was an unsuccessful attempt to unify both states in 1996, and the states still cooperate on many matters.
