The commune of Ghardaïa has a population of 104,645, with 82,500 in the main city according to 2005 estimates. It is located in northern-central Algeria in the Sahara Desert and lies along the left bank of the Wadi Mzab. The M'zab valley in the Ghardaïa Province (Wilaya) was inscribed under the UNESCO World Heritage List in 1982, as a cultural property evaluated under the criteria II ( for its settlement having an impact on urban planning even to the present century), III (for its Ibadi cultural values), and V (a settlement culture which has prevailed to the present century).

Ghardaïa is part of a pentapolis, a hilltop city amongst four others, built almost a thousand years ago, and founded by the Mozabites a Muslim Ibadi sect (non-Arabic Muslims, including the Berbers) in the M’Zab valley. It is a major centre of date production and the manufacture of rugs and cloths. Divided into three walled sectors, it is a fortified town. At the centre is the historical Mʾzabite area, with a pyramid-style mosque and an arcaded square. Distinctive white, pink, and red houses, made of sand, clay and gypsum, rise in terraces and arcades. In her 1963 book, La force des choses the French existentialist philosopher Simone de Beauvoir described Ghardaia as "a Cubist painting beautifully constructed".
