Highgate ( HY-gayt) is a suburban area of north London at the northeastern corner of Hampstead Heath, 4+1⁄2 miles (7 kilometres) north-northwest of Charing Cross.

Highgate is one of the most expensive London suburbs in which to live. It has three active conservation organisations, the Highgate Society, the Highgate Neighbourhood Forum and the Highgate Conservation Area Advisory Committee to protect and enhance its character and amenities.

Until late Victorian times it was a distinct village outside London, sitting astride the main road to the north. The area retains many green expanses including the eastern part of Hampstead Heath, three ancient woods, Waterlow Park and the eastern-facing slopes known as Highgate bowl.

At its centre is Highgate village, largely a collection of Georgian shops, pubs, restaurants and residential streets interspersed with diverse landmarks such as St Michael's Church and steeple, St. Joseph's Church and its green copper dome, Highgate School (1565), Jacksons Lane arts centre housed in a Grade II listed former church, the Gatehouse Inn dating from 1670 which houses the theatre Upstairs at the Gatehouse and Berthold Lubetkin's 1930s Highpoint buildings. Pond Square, behind the High Street, is a registered village green and is the centre of communal activities which take place in the elegant buildings of the Highgate Literary and Scientific Institution and Highgate Society facing the Square.

Highgate is perhaps best known for the Victorian Highgate Cemetery in which the Communist philosopher Karl Marx and the novelist George Eliot are buried, along with many other notable people.

The village is at the top of Highgate Hill, which provides views across central London. Highgate is 136 m (446 ft) above sea level at its highest point.

The area is divided among three London boroughs: Haringey in the north, Camden in the south and west, and Islington in the south and east. The postal district is N6.
