Sidi Abdellah is a planned community in Algeria in the southwestern suburbs of Algiers.

It was created as a model of sustainable development by emphasizing an open urban fabric that does not suffer from the stifling overcrowding in the neighborhoods of Algiers inherited from the French occupation of Algeria.

Sidi Abdellah is 20 kilometres (12 mi) southwest of the Wilayah of Algiers.

[1] The Sidi Abdellah city project has a total area of 7,000 hectares (17,297 acres), i.e.,70 square kilometres (27 sq mi), of which 45% — an area of 3,158 hectares (7,804 acres), i.e.,31.6 square kilometres (12.2 sq mi) — is urbanized.

When it was created in 2004, Sidi Abdellah was projected to include 54,000 dwellings and 270,000 inhabitants when completed.
