Which country has the largest area of the Sahara Desert?

Algeria contains the largest area of the Sahara Desert of any country.

The Sahara covers most of Algeria, especially the country’s enormous southern regions. Because Algeria is Africa’s largest country overall, its share of the Sahara is also greater than that of any other nation.

The Algerian Sahara includes sand seas, rocky plateaus, mountain ranges, and oases. The Hoggar Mountains rise in the far south, while settlements such as Tamanrasset connect desert communities with the country’s northern regions. Despite its aridity, the Sahara is not a featureless sea of sand; only some parts are covered by dunes.

Libya, Egypt, Niger, Mali, Mauritania, Chad, Sudan, and Tunisia also contain the Sahara. The desert itself crosses national borders and is defined by climate and landscape rather than by political boundaries.
