The bin Laden family (, bin Ladin), also spelled bin Ladin, is a wealthy family intimately connected with the innermost circles of the Saudi royal family. The family was thrown into the media spotlight through the activities of one of its members, Osama bin Laden, the former head of Al Qaeda, the terrorist group responsible for the September 11, 2001 terror attacks on US government and commercial buildings. The financial interests of the bin Laden family are represented by the Saudi Binladin Group, a global oil and equity management conglomerate grossing US$2 billion annually, and the largest construction firm in the world, with offices in London, Dubai, and Geneva.
