Broadwater Farm, often referred to simply as "The Farm", is an area in Tottenham, North London, straddling the River Moselle. The eastern half of the area is dominated by the Broadwater Farm Estate ("BWFE"), an experiment in high-density social housing, loosely based on Corbusian ideas, dominated by concrete towers connected by walkways (the controversial, so-called "Streets in the sky"), built in the late 1960s using cheap but fire-vulnerable pre-fabricated concrete panels. The western half of the area is taken up by Lordship Recreation Ground, one of north London's largest parks. Broadwater Farm in 2011 had a population of 4,844. The estate is owned by Haringey London Borough Council.

Following the publication of Alice Coleman's Utopia on Trial in 1985, the area acquired a reputation as one of the worst places to live in the United Kingdom. This perception was exacerbated when serious rioting erupted later that year.

After the 1985 riot there was a major redevelopment programme, after which crime rates initially fell. However, it is still associated with gangs with numerous stabbings and other violent crime occurring in and around the area.

Well known for its large Afro-Caribbean heritage, it is one of the most ethnically diverse locations in London; in 2005 its official population of 3,800 included residents of 39 different nationalities.

Broadwater Farm was completed in the early 1970s and built using the same Taylor Woodrow-Anglian system of prefabricated panels as Ronan Point. In June 2018, following tests conducted after the Grenfell Tower fire, Haringey Council announced hundreds of families would have to be evacuated because eleven of the towers are at risk of catastrophic collapse in the event of a fire. At least two may have to be demolished.^{[needs update]}

Broadwater Farm is situated in the valley of the Moselle, approximately six miles (ten kilometres) north of the City of London. It is situated in a deep depression immediately south of Lordship Lane, between the twin junctions of Lordship Lane and The Roundway. It is immediately adjacent to Bruce Castle, approximately 550 yards (500 metres) from the centre of Tottenham, and 1+1⁄4 miles (2 kilometres) from Wood Green.

Until the opening of the nearby Bruce Grove railway station on 22 July 1872 the area was still rural, although close in proximity to London and the growing suburb of Tottenham. Aside from a small group of buildings clustered around neighbouring Bruce Castle, the only buildings in the area were the farmhouse and outbuildings of Broadwater Farm, then still a working farm.

Following construction of the railways to Tottenham and Wood Green, suburban residential development in the surrounding area took place rapidly. However, due to waterlogging and flooding caused by the River Moselle, Broadwater Farm was considered unsuitable for development and remained as farmland. By 1920, Broadwater Farm was the last remaining agricultural land on Lordship Lane, surrounded by housing on all sides.
