The siege of Mazagan of 1562, also known as the Great Siege of Mazagan (Portuguese: Grande Cerco de Mazagão) was an armed engagement that took place in the modern city of El Jadida, then known as Mazagan, between Portuguese forces and those of the Saadi dynasty, which had unified Morocco a few years prior. The Moroccans ultimately failed to breach the defenses of the city, and in the face of continuous Portuguese reinforcements and vigorous defence were forced to withdraw after a two and a half month long siege. It was one of the hardest fought sieges withstood by the Portuguese at Mazagan, of a total of nine.
