The Øresund Region (Danish: Øresundsregionen [ˈøːɐsɔnsʁekiˌoˀnn̩]; Swedish: Öresundsregionen [œːrɛˈsɵ̂nːdsrɛɡɪˌuːnɛn]), also known as the Greater Copenhagen Region for marketing purposes, is a transnational metropolitan region encompassing the Capital Region of Denmark and Region Zealand in eastern Denmark and Region Skåne in southern Sweden. Centred around the Øresund strait and the two cities which lie on either side, Copenhagen in Denmark and Malmö in Sweden, the region is connected by the Øresund Bridge, which spans the strait at its southern end, and the HH Ferry route between Helsingør, Denmark, and Helsingborg, Sweden, at the narrowest point of the strait.
The region has a population of app. 4.5 million (2023) and a population density of 170/km (440/sq mi). The Øresund Region consists of both rural and urban areas. Areas on the periphery of the region have a relatively low population density, whereas the two metropolitan areas of Copenhagen and Malmö are two of the most densely populated in Scandinavia. Helsingborg also forms an important urban hub on the Swedish side.
