The Alhucemas Islands is a group of islands and one of the Spanish plazas de soberanía just off the Moroccan coast in the Alboran Sea.

The plazas de soberanía are a series of Spanish overseas minor territories scattered along the Mediterranean coast bordering Morocco in Africa, or that are closer to Africa than Europe. This term is used for those territories that have been a part of Spain since the formation of the modern country (1492–1556), as opposed to African territories acquired by Spain during the 19th and early 20th centuries in the Scramble for Africa.
