La Güera (Arabic: الڭويرة al-Gūwayra; also known as La Agüera, Lagouira, El Gouera) is a ghost town on the Atlantic coast at the southern tip of Western Sahara, on the western side of the Ras Nouadhibou peninsula which is split in two by the Mauritania–Western Sahara border, 15 kilometres (9.3 mi) west of Nouadhibou.

La Güera is situated about 65 kilometres (40 mi) south of the Moroccan Wall at Guerguerat and is technically abandoned.

La Güera came into existence in late 1920, when Spanish colonizer Francisco Bens (who had earlier taken possession of the Cape Juby region as a protectorate in 1916), after negotiating with tribal chiefs of the zone, established a fort and an air base on the western side of the Ras Nouadhibou peninsula, just a few kilometers away from the French settlement of Port-Étienne (now Nouadhibou) on the eastern side of the peninsula.

(In the 1912 Convention of Madrid, Spain and France had agreed on a border between Mauritania and Spanish possessions that ran down the middle of the peninsula.)

During the short period (1920–1924) that the town was ruled as a separate part of the colony it released its own postage stamps.
