The Costa del Sol (Spanish: [ˈkosta ðel ˈsol]; literally "Coast of the Sun") is a region in the south of Spain in the autonomous community of Andalusia, comprising the coastal towns and communities along the coastline of the Province of Málaga and the eastern part of Campo de Gibraltar in Cádiz. Formerly made up only of a series of small fishing settlements, today the region is a world-renowned tourist destination. The Costa del Sol is situated between two lesser known coastal regions, the Costa de la Luz and the Costa Tropical.
The region has no official limit, but it is generally accepted that the Costa del Sol stretches from the municipality of La Línea de la Concepción in the west to Nerja in the east, spanning around 150 kilometers of coastline. The term Costa del Sol was coined at the beginning of the 20th century by Rodolfo Lussnigg to promote the Almería coastline. Until the late 1960s, it was used in reference to the entire Mediterranean coast of Eastern Andalusia. The name refers to the sunny climate, present in the region most days of the year. The Costa del Sol is one of the most important tourist areas in Spain; around 35% of Andalusia's tourism is concentrated in the region; in 2009 it had 17 million overnight stays.
