The Langue de Barbarie (french for "Barbary tongue") is a thin, sandy peninsula, adjacent to the Atlantic Ocean, located in western Senegal, in the neighbourhood of the city of Saint-Louis.. The peninsula separates the ocean from the final section of the Senegal River. It is also the location of a national park, the Parc National de la Langue de Barbarie, which is home to an abundant variety of bird species. A 4 metres (13 ft) breach was cut in the peninsula near the city of Saint-Louis on 3 October 2003 to help counter possible inundations. However, the breach quickly widened to 800 m (2,600 ft) and separated the southern end of the peninsula permanently from the main country, effectively transforming it into an island.
