Yes — the Iberian Peninsula comprises Spain and Portugal (together ~95% of its land area), plus a small portion of southern France (Pyrénées-Orientales department) and the British Overseas Territory of Gibraltar.
Occupies most of the peninsula — Meseta Central, Cantabrian, Iberian, and Baetic mountain systems.
Western coastal strip — distinct geology (Hercynian basement), Atlantic-facing culture.
Northern foothills of Pyrenees — culturally Catalan (Roussillon).
British since 1713; strategic choke point at Mediterranean entrance.
The peninsula's isolated yet connected position — linked to Europe only by the Pyrenees, open to Atlantic and Med — forged unique histories: Reconquista, Atlantic empires, distinct languages (Castilian, Portuguese, Catalan, Basque, Galician), and a shared Mediterranean climate.
Spain and Portugal are the Iberian Peninsula — but the edges tell stories too.
