What Country Is Directly West of Lisbon? None—Atlantic Ocean

Portugal's Western Frontier

Lisbon (and all of mainland Portugal) has no land neighbor to the west. The country's western border is the Atlantic Ocean.

Portugal's Land Borders

• North & East: Spain (only land neighbor).
• West & South: Atlantic Ocean.

Maritime Neighbors (West/Southwest)

• Azores (autonomous region of Portugal) – ~1,360 km W.
• Madeira (autonomous region) – ~970 km SW.
• Morocco – ~800 km S (across Strait of Gibraltar).

So, strictly speaking: No nation lies west of Lisbon—only the Atlantic.
