The Iberian Peninsula (IPA: eye-BEER-ee-ən), also known as Iberia, is a peninsula in southwestern Europe.

Mostly separated from the rest of continental Europe by the Pyrenees, the Iberian Peninsula includes Peninsular Spain and Continental Portugal, which together make up almost all of the region, as well as Andorra, Gibraltar, and a small part of Metropolitan France. With an area of approximately 583,254 square kilometres (225,196 sq mi), and a population of roughly 53 million, it is the second-largest European peninsula by area, after the Scandinavian Peninsula.

Etymology

The Iberian Peninsula has always been associated with the River Ebro (Ibēros in ancient Greek and Ibērus or Hibērus in Latin). The association was so well known it was hardly necessary to state. For example, Ibēria was the country "this side of the Ibērus" in Strabo. Pliny goes so far as to assert that the Greeks had called "the whole of the peninsula" Hiberia because of the Hiberus River.

The river appears in the Ebro Treaty of 226 BCE between Rome and Carthage, setting the limit of Carthaginian interest at the Ebro. The fullest description of the treaty, stated in Appian, uses Ibērus. With reference to this border, Polybius states that the "native name" is Ibēr, apparently the original word, stripped of its Greek or Latin -os or -us termination.

The early range of these natives, which geographers and historians place from the present southern Spain to the present southern France along the Mediterranean coast, is marked by instances of a readable script expressing a yet unknown language, dubbed "Iberian". Whether this was the native name or was given to them by the Greeks for their residence near the Ebro remains unknown. Credence in Polybius imposes certain limitations on etymologizing: if the language remains unknown, the meanings of the words, including Iber, must also remain unknown.

In modern Basque, the word ibar means "valley" or "watered meadow", while ibai means "river", but there is no proof connecting the names with Ebro or Iberia.
