>La Línea de la Concepción (more often referred to as La Línea) is a town in Spain, in the province of Cádiz in Andalucia. It lies on the eastern isthmus of the Bay of Gibraltar on the border with the British overseas territory of Gibraltar, with which it has close economic and social links. It is situated on the sandy isthmus which unites the Rock of Gibraltar with the coast in the eastern flank of the Bay of Gibraltar, between Sierra Carbonera and the Rock of Gibraltar.

The town derives its name firstly from the línea or boundary line separating Spain from Gibraltar and secondly from the Immaculate Conception of Mary, the Mother of Jesus. Its people are called in Spanish linenses.

The first dwellings date back to the 18th century, which were behind the Spanish lines, being part of the municipality of San Roque until 1870, when it became separate.
