Western Norway (Bokmål: Vestlandet, Vest-Norge; Nynorsk: Vestlandet, Vest-Noreg) is the region along the Atlantic coast of southern Norway. It consists of the counties Rogaland, Vestland, and Møre og Romsdal. The region has no official or political-administrative function. The region has a population of approximately 1.4 million people. The largest city is Bergen and the second-largest is Stavanger. Historically the regions of Agder, Vest-Telemark, Hallingdal, Valdres, and northern parts of Gudbrandsdal have been included in Western Norway.
Western Norway, as well as other parts of historical regions of Norway, shares a common history with Denmark, the Faroe Islands and Iceland and to a lesser extent the Netherlands and Britain. For example, the Icelandic horse is a close relative of the Fjord horse and both the Faroese and Icelandic languages are based on the Old West Norse.
