{{Short description|Geographical region of Wales}} {{for|the region formerly called West Wales|Dumnonia}} [[File:West Wales.svg|thumb|A common definition of West Wales, covering Carmarthenshire, Ceredigion and Pembrokeshire. Other definitions may exist.]] '''West Wales''' ({{langx|cy|Gorllewin Cymru}}) is a region of Wales.

It has various definitions, either covering Pembrokeshire, Ceredigion and Carmarthenshire, which historically comprised the Welsh principality of ''Deheubarth'', and an alternative definition is to include Swansea and Neath Port Talbot, but exclude Ceredigion (corresponding to South West Wales). The West Wales and the Valleys NUTS area also includes more westerly parts of North Wales as well as the South Wales Valleys.

The preserved county of Dyfed covers what is generally considered to be West Wales; between 1974 and 1996, Dyfed was a county, with a county council and six district councils.

==Historic use== Historically, the term West Wales was applied to the Kingdom of Cornwall during the Anglo-Saxon invasion of Britain and the period of the Heptarchy.<ref>{{Cite web|url=http://www.lib.utexas.edu/maps/historical/shepherd/british_isles_802.jpg|title=The Historical Atlas by William R. Shepherd, 1926}}</ref> The Old English word ''Wealas'', a Germanic term for inhabitants of the Western Roman Empire, which the Anglo-Saxons came to apply especially to the Britons, gave its name to Wales and is also the origin of the second syllable in the name Cornwall.
