Nouadhibou (Arabic: نواذيبو; formerly Port-Étienne) is the second largest city in Mauritania and serves as a major commercial centre. The city itself has about 118,000 inhabitants expanding to over 140,000 in the larger metropolitan area, a total of nearly 95% of the entire regional population and is the country's economic capital. It is situated on a 65-kilometre peninsula or headland called Ras Nouadhibou, Cap Blanc, or Cabo Blanco, of which the western side, with the city of La Güera, is part of Western Sahara. Nouadhibou is consequently located merely a couple of kilometres from the border between Mauritania and Western Sahara. Its current mayor is Mohamed Fadel ould Aboubekrine.
