Altea (Valencian: [aɫˈtea], Spanish: [alˈtea]) is a town and municipality located in the province of Alicante, Spain, north of Alicante on the section of Mediterranean coast called the Costa Blanca.

At present, the economy of Altea is based on tourism, which started to grow in the 1950s because of its good weather, beaches and the labyrinthine streets with whitewashed house-fronts that characterize the town. Altea is protected on the north by the bluffs of the Serra de Bèrnia, creating an especially mild microclimate. Its seafront esplanade is planted with palms.
