Diar el Mahçoul (Arabic: ديار المحصول‎, lit. 'land of plenty') is a residential complex and district of Algiers, Algeria, split between the quarters of Belouizdad and El Madania. Diar el Mahçoul was developed by French modernist architect and urban planner Fernand Pouillon between 1953 and 1955. The Martyrs' Memorial (Arabic: مقام الشهيد‎,‎), which houses the National Museum of El Mujahid, stands at the edge of the development. The structure, constructed in 1982, is one of the city's most recognizable buildings.
