What is the name of the peninsula that contains both Spain and Portugal?

The peninsula that contains both Spain and Portugal is the Iberian Peninsula. It occupies southwestern Europe and is named after the ancient Iberian peoples who lived there before Roman rule.

Spain and Portugal make up most of the peninsula, but it also includes Andorra, Gibraltar, a small part of France, and several disputed or geographically marginal areas. The Pyrenees form its northeastern boundary with the rest of Europe, while the Atlantic Ocean borders much of its western and northern coast. The Mediterranean Sea lies to the east and southeast.

The Iberian Peninsula is sometimes confused with the Italian or Balkan peninsulas, which are the other major southern European peninsulas. Its history includes Roman Hispania, centuries of Muslim rule in al-Andalus, the Christian kingdoms of medieval Iberia, and the eventual formation of modern Spain and Portugal. The region also gave Portugal and Spain a base for major overseas exploration from the 15th century onward.
