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.

A citadel is the most fortified area of a town or city. It may be a castle, fortress, or fortified center. The term is a diminutive of city, meaning "little city", because it is a smaller part of the city of which it is the defensive core.
