There are eleven metropolitan regions in Germany consisting of the country's most densely populated cities and their catchment areas. They represent Germany's political, commercial and cultural centres. The eleven metropolitan regions in Germany were organised into political units for planning purposes.

The Hamburg Metropolitan Region is a metropolitan area centred around the city of Hamburg in northern Germany, consisting of eight districts in the federal state of Lower Saxony, six districts 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.
