The Øresund Region, also known as Greater Copenhagen, is a metropolitan region encompassing the Capital Region and Region Zealand in eastern Denmark and Region Skåne and Region Halland 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 Øresund or Öresund Bridge is a combined railway and motorway cable-stayed bridge across the Øresund strait between Denmark and Sweden. It is the second longest bridge in Europe with both roadway and railway combined in a single structure, running nearly 8 kilometres from the Swedish coast to the artificial island Peberholm in the middle of the strait. The crossing is completed by the 4-kilometre (2.5 mi) Drogden Tunnel from Peberholm to the Danish island of Amager.
