Of all the countries which border the Mediterranean Sea, which has the largest area?

While one might picture European nations like France or Spain, the title for the largest Mediterranean country by area belongs to a North African giant. The key to this answer lies not on the coast, but deep inland. Algeria's immense size is primarily due to its massive portion of the Sahara Desert, which makes up more than 80% of its territory. This vast, arid expanse gives it a total area of nearly 2.4 million square kilometers.

This staggering size makes Algeria the largest country in all of Africa, the largest in the Arab world, and the 10th largest country on the planet. While other Mediterranean nations like Egypt and Libya also have significant desert regions, neither matches the sheer scale of Algeria's Saharan territory.

This geography creates a nation of stark contrasts. The overwhelming majority of the Algerian population lives along the fertile northern coastal strip, enjoying a typical Mediterranean climate. This thin, densely populated region stands in sharp opposition to the vast, almost empty interior, making Algeria a country defined as much by the sea at its northern edge as by the immense desert to its south.
