The sieges of Oran and Mers El Kébir of 1563 represented a major Hispano-Algerian episode in the larger Ottoman-Habsburg wars of the Mediterranean. Between April and June 1563 the Regency of Algiers launched a major military campaign to retake the Spanish military-bases of Oran and Mers el Kébir on the North African coast, occupied by Spain since 1505. The Kingdom of Algiers, the Principalities of Kabyle, and other vassal tribes combined forces as one army under Hasan Pasha, son of Hayreddin Barbarossa, and Jafar Catania. The Spanish commander brothers, Alonso de Córdoba Count of Alcaudete and Martín de Córdoba, managed to hold the strongholds of Oran and Mers El Kébir, respectively, until the relief fleet of Francisco de Mendoza arrived to successfully defeat the offensive.

Both Spaniards and Algerines fought poorly, but Barceló, blaming unfavorable weather conditions, gave the order to withdraw. His expedition was judged a failure at the Spanish court, being described as a "festival of fireworks too costly and long for how little it entertained the Moors and how it was used by whomever paid for it".

The European enclaves in North Africa were towns, fortifications and trading posts on the Mediterranean and Atlantic coasts of western North Africa, obtained by various European powers in the period before they had the military capacity to occupy the interior. The earliest medieval enclaves were established in the 11th century CE by the Italian Kingdom of Sicily and Maritime republics; Spain and Portugal were the main European powers involved; both France and, briefly, England also had a presence. Most of these enclaves had been evacuated by the late 18th century, and today only the Spanish possessions of Ceuta, Melilla, and the Plazas de soberanía remain.
