A presidio (jail, fortification) was a fortified base established by the Spanish Empire mainly between the 16th and 18th centuries in areas under their control or influence. The term is derived from the Latin word praesidium meaning protection or defense.

In the Mediterranean and the Philippines, the presidios were outposts of defense against raids by Muslims. In the Americas, the fortresses were built to protect against raids by pirates, rival colonial powers, and Native Americans.

Later in western North America, with independence, the Mexicans garrisoned the Spanish presidios on the northern frontier and followed the same pattern in unsettled frontier regions such as the Sonoma Barracks in what is now California and the Presidio de Calabasas in what is now Arizona.

In western North America, a rancho del rey or kings ranch would be established a short distance outside a presidio. This was a tract of land assigned to the presidio to furnish pasturage to the horses and other beasts of burden of the garrison. Mexico called this facility a rancho nacional. Presidios were only accessible to Spanish military and soldiers.

Several fortresses formerly held by the Republic of Siena were acquired by Spain following the latter's demise, by treaty between Philip II of Spain and Cosimo I de' Medici, Grand Duke of Tuscany on 3 July 1557, to form what became known as the Estado de los Presidios. They were held by Spain until the War of the Spanish Succession, when they came under Austrian ownership, and were administered from Naples.

Mexico Few presidios were established in the present-day desert frontier regions in northern Mexico to control and confine the existing rebellious indigenous tribes."Spanish policymakers also decided to set up a line of presidios stretching from the Atlantic to the Pacific. This presidial line was very close to today's international border between Mexico and the United States." Reséndez, Andrés. The Other Slavery: The Uncovered Story of Indian Enslavement in America (p. 198). Houghton Mifflin Harcourt. Kindle Edition. Captured indigenous warriors were confined and enslaved at the presidio."As the eighteenth century unfolded, military garrisons and soldiers superseded the missions as the lynchpins of Spain's efforts to stabilize the frontier. With the new approach came new forms of coercion. The word “presidio” captures the dual purpose of garrison and prison." Reséndez, Andrés. The Other Slavery: The Uncovered Story of Indian Enslavement in America (p. 205). Houghton Mifflin Harcourt. Kindle Edition. Presidios was used to protect the colonial silver ship from rebellious raids from Indians in Camino Real de Tierra Adentro, mainly in Zacatecas and Guanajuato, starting new settlements.

North Africa

After the Granada War and the completion of the Spanish Reconquista, the Catholic Monarchs took their fight across the Strait of Gibraltar, as the Portuguese had done several generations earlier with the conquest of Ceuta in 1415. The establishment of Spanish military outposts on the North African coast echoed earlier endeavors by the Kingdom of Sicily in the 12th century (and again in Djerba under Frederick III of Sicily) and the Kingdom of France in the 13th century (Eighth Crusade of 1270). During the period of Iberian Union between 1580 and 1640, the Spanish Crown gained Ceuta and the Portuguese outposts on the Atlantic Coast, such as Tangier, Mazagão/El Jadida and Casablanca; but of these, it only retained Ceuta by the Treaty of Lisbon (1668).

The Spanish North African presidios are listed here in geographical sequence, from West to East, and including neither Spain's Atlantic settlements in the Moroccan far South (e.g. Santa Cruz de la Mar Pequeña) nor outposts gained after 1830 (e.g. the Chafarinas Islands).
