The 1999 London nail bombings were a series of bomb explosions in London, England. Over three successive weekends between 17 and 30 April 1999, homemade nail bombs were detonated in Brixton in South London; at Brick Lane, Spitalfields, in the East End; and at the Admiral Duncan pub in Soho in the West End. Each bomb contained up to 1,500 4-inch (100 mm) nails, in holdalls that were left in public spaces. The bombs killed three people and injured 140 people, four of whom lost limbs.

Brixton is an area of South London, part of the London Borough of Lambeth, England. The area is identified in the London Plan as one of 35 major centres in Greater London. Brixton experienced a rapid rise in population during the 19th century as communications with central London improved.
