Boumerdès (Arabic: ولاية بومرداس, Kabyle: Tanebḍit n Bumerdas) is a province (wilaya) of northern Algeria, located in the Kabylia region, between Algiers and Tizi-Ouzou, with its capital at the coastal city of Boumerdès (formerly Rocher-Noir) just east of Algiers.

The three towns of Zemmouri El Bahri (Rusubbicari), Djinet (Cissi), and Dellys (Rusucurium), all of Phoenician foundation, were the province's principal ancient sites, although smaller Roman towns existed inland, as at Thenia called Nubel's Citadel [fr], at Taourga; at none do any significant classical ruins remain.

Boumerdès itself, called Rocher-Noir in the colonial period, was expanded substantially following the establishment of the new wilaya in 1984.

Since 2003, the area encompassing this province has been classified as a high seismic risk region to make adequate technical provisions during the construction of houses and buildings.
