The Alcazaba is a palatial fortification in Málaga, Spain, built during the period of Muslim-ruled Al-Andalus. The current complex was begun in the 11th century and was modified or rebuilt multiple times up to the 14th century. It is one of the best-preserved alcazabas in Spain. The Alcazaba is also connected by a walled corridor to the higher Castle of Gibralfaro, and adjacent to the entrance of the Alcazaba are remnants of a Roman theatre dating to the 1st century AD.

A kasbah, also spelled qasba, qasaba, or casbah, is a fortress, most commonly the citadel or fortified quarter of a city. It is also equivalent to the term alcazaba in Spanish, which is derived from the same Arabic word. By extension, the term can also refer to a medina quarter, particularly in Algeria. In various languages, the Arabic word, or local words borrowed from the Arabic word, can also refer to a settlement, a fort, a watchtower, or a blockhouse.
