Map - Capital Region of Denmark (Region Hovedstaden)

The Capital Region of Denmark (Region Hovedstaden, ) is the easternmost administrative region of Denmark. The Capital Region has 29 municipalities and a regional council consisting of 41 elected members. As of 1 August 2021 the chairperson is Lars Gaardhøj, who is a member of the Social Democrats party of Denmark.

The Capital Region was established on 1 January 2007 as part of the 2007 Danish Municipal Reform. This reform abolished the traditional counties (Danish plural: amter, singular: amt) and created five regions. As part of this reform 271 smaller municipalities were merged into larger units reducing the number of municipalities to 98.

The reform dramatically diminished the power of regional governments while enhancing that of local government and that of the central government in Copenhagen. It was implemented on 1 January 2007.

Unlike the former counties (1970–2006) (Danish Amtskommune, literally 'county municipality') the regions are not municipalities and are thus not allowed to have a coat of arms, only logotypes.

The regions do not collect taxes and are financed primarily through block grants, they are unable to transfer money from one area of expenditure to another, and they must return any unused money to the central government. This makes the regions more like departments or agencies of the central government.

The main industries in the region are hospitals and healthcare. The Capital Region is not to be confused with the Copenhagen Metropolitan Area or the Øresund Region.

The Capital Region of Denmark is one of five regions in Denmark and consists of the municipalities of Copenhagen and Frederiksberg, the former counties of Copenhagen and Frederiksborg, and the regional municipality of Bornholm. The Danish name for this region is Region Hovedstaden. It borders Zealand and Sweden's Skåne County via the Øresund Bridge.

Denmark's largest lake (Danish sø), Arresø, lies 43 kilometers (28 miles) northwest of Copenhagen. There are several other lakes, the deepest in Denmark being Furesø, 14.5 km (9 miles) northwest of Copenhagen, which is the namesake of the Furesø Municipality. Among several forests, the region also has the Gribskov forest, which is the namesake of the Gribskov Municipality. The Dyrehaven forest park is just north of Copenhagen (and east of Furesø) in the Gentofte Municipality and the Lyngby-Taarbæk Municipality.

Geologically, the region lies in the northern part of Denmark, which is rising because of post-glacial rebound, making lakes out of former inlets and bays. Arresø is one example, having extended in a northwesterly direction as a part of Brødemose Sund into Kattegat. (The land is rising by 9 millimeters every year in Furuögrund, the northeastern part of Skellefteå Municipality, north of Kvarken.) Because of the mobility of the sand dunes, forests have been planted along the coast of Kattegat in the municipalities of Helsingør, Gribskov, and Halsnæs.

For the purpose of a road and rail connection to Øresund Bridge, land has been added to the island of Amager, which has a tunnel connecting it with the artificial island Peberholm just south of the island of Saltholm. The land area of east Denmark (east of the Great Belt strait) is approximately 9,622 km2 (3,715 sq mi), which is set to increase due to housing projects in the north of Copenhagen Municipality, and also due to new bridges and tunnels being added, including the Fehmarn Belt Fixed Link and other traffic infrastructure projects. A new high-speed train line called the Copenhagen-Ringsted Line came into operation on 1 June 2019 to increase transport capacity and relieve congestion in Roskilde and the narrow 9-9.5 mile isthmus between Roskilde Fjord and the bay of Køge Bugt. It does this by moving international and national train traffic to the new train line and only keeping local and regional traffic.
