The Capital Region is a region in southwestern Iceland that comprises the national capital Reykjavík and six municipalities around it. Each municipality has its own elected council. Municipal governments in the region cooperate extensively in various fields: for example waste policy, shared public transport and a joint fire brigade. The region is home to 64% of Iceland's population.
The region contains Iceland's largest urban area by far, Greater Reykjavík, a conurbation that includes parts of six out of seven municipalities of the region.
