Atlantic Europe is a geographical and anthropological term for the western portion of Europe which borders the Atlantic Ocean. The term may refer to the idea of Atlantic Europe as a cultural unit and/or as an biogeographical region.
It comprises the British Isles (UK and Ireland), Iceland, Belgium, the Netherlands, the central and northern regions of Portugal (sometimes Portugal as a whole is referenced), northwestern and northern Spain, the western portion of France and Scandinavia and northern Germany.
Weather and overall physical conditions are relatively similar along this area (with the exception of parts of Scandinavia and the Baltic), resulting in similar landscapes with common endemic plant and animal species. From a strictly physical point of view most of the Atlantic European shoreline can be considered a single biogeographical region. Physical geographers label this biogeographical area as the European Atlantic Domain, part of the Euro-Siberian botanic region.
Archaeologists have noted that the prehistoric peoples of Atlantic Europe presented some common traits, as shown by artifacts and architectural styles found in the region which attest to at least some form of trade link. In addition, a number of genetic studies seem to interrelate specific groups of population in parts of Atlantic Europe in contrast with, for example, Central or Mediterranean Europe.
Some examples of early cultural contact are the European Megalithic Culture and the Atlantic Bronze Age, or "carp's tongue sword complex". This refers to an industry mainly based on the west coast of France and Brittany but which clearly had links with societies in Iberia and Britain, as evidenced by products such as the carp's tongue sword and the end winged axe, which were widely bought and sold along the routes of the Atlantic seaways.
Culture at present 
A number of authors have postulated that there still is a cultural continuum in Atlantic Europe, forming a cultural unit which has its roots in prehistoric times but remained until today mostly thanks to sea trade. Geographers also mention the influence of the natural environment in the construction of a similar cultural landscape along the western European coasts. Some of the first geographers to consider this idea of Atlantic Europe were Otero Pedrayo and Orlando Ribeiro. Pedrayo stated in his studies about Galicia that this territory was marked by a strong "Atlantic character", not Mediterranean, despite the fact of being part of a Mediterranean state (Spain). On the other hand, while researching about his native Portugal, Ribeiro deepened the concepts of Atlantic Europe and Mediterranean Europe, linking southern Portugal more towards the Mediterranean culture and central and northern Portugal (together with Galicia and Asturias) to a pan-Atlantic European culture.
This idea would be further developed from the 1950s onwards by authors such as P. Flatrès, Emyr Estyn Evans, A. Bouhier, Meynier, J. García Fernández, Patrick O'Flanagan, Barry Cunliffe, Carlos Ferrás Sexto and Xoán M. Paredes (among others). Patrick O'Flanagan, based on the theories of Pedrayo and Ribeiro, states that Atlantic Europe is a cultural reality that stretches along the coastal fringe of Europe, from Norway to South-Central Portugal (roughly down to the Santarém area), and including Britain and Ireland.
Bob Quinn in his documentary series Atlantean speculates that western European Celtic culture is actually an earlier, pre-Celtic, Atlantic culture that included Atlantic Europe and people of the Maghreb such as Berbers and that it continues today.
Atlantic Europe in politics 
There is a multi-national association of regions, which acts as a co-ordinator of Atlantic European regions and its interests. This is the Atlantic Arc Commission. Operative since 1989, it includes 26 regions from four member States - Great Britain, France, Spain and Portugal. The Atlantic Arc Commission is one of the seven Geographical Commissions in the Conference of Peripheral Maritime Regions of Europe.
