Descriptions
Tunisia
Algeria’s northeastern neighbor, Tunisia is known for its Mediterranean beaches, ancient Carthaginian ruins, and shared cultural history. The border runs through the Atlas Mountains and is a key corridor for regional trade and travel between the two Maghreb nations.
Libya
To the east, Algeria shares a vast desert border with Libya. Both are significant North African oil and gas producers. This remote frontier crosses the expansive Sahara Desert, a landscape of sand seas and rocky plateaus historically traversed by nomadic peoples.
Niger
Niger lies to Algeria’s southeast, a landlocked Sahelian nation with a rich history of trans-Saharan trade. The border region is a gateway between North and Sub-Saharan Africa, home to Tuareg communities who have lived in the area for centuries.
Mali
Sharing Algeria’s longest land border to the south, Mali is famed for the legendary city of Timbuktu and its vibrant musical heritage. The border slices deep into the Sahara, an area critical for regional stability and historical caravan routes.
Mauritania
Situated to the southwest, Mauritania acts as a bridge between Arab North Africa and Sub-Saharan Africa. The shared border is located in one of the most remote and sparsely populated parts of the Sahara Desert, recently seeing new trade-focused border crossings.
Morocco
Algeria’s western neighbor is the Kingdom of Morocco, a country with diverse landscapes from Atlantic beaches to the Atlas Mountains. Despite their long border and shared culture, the land frontier between the two nations has been officially closed since 1994.
