Dover Heights borders Vaucluse to its north, North Bondi to its south and Rose Bay to its west and has the Pacific Ocean to its east.

Dover Heights is a mainly residential suburb. Many of the suburb's properties have views of Sydney Harbour and the Sydney Harbour Bridge, making its Dudley Page Reserve a popular site for tourist buses. Some properties have both harbour and ocean views.

The suburb is considered to be the most affluent within the Waverley Local Government Area, and amongst the most affluent suburbs in Sydney. This is reflected in property prices - like nearby suburbs Vaucluse and Bellevue Hill, median house prices are above A$2 million.

Dover Heights is believed to have been named for its cliffs along the Pacific Ocean which resembled those found at Dover, in Kent, England. The first mention of Dover Heights appeared in municipal records in 1886. The area was first used for market gardens.

In 1830 land in the area was owned by Daniel Cooper (1785?1853), a partner in the firm Cooper and Levey, who owned the Waterloo Stores. The retailing emporium was located on the corner of George Street and Market Street in the city, on the site that was later occupied by Gowings Brothers retailers until 2006. The Dover Heights area was subdivided in 1913.

During the Second World War, Rodney Reserve, at the Dover Heights clifftop, was used by the Royal Australian Air Force for coastal defence RADAR. The CSIRO further used the site for pioneering experimentation in radio astronomy related to galactic radio emissions, with a team including John Gatenby Bolton first observing solar emissions in 1945.
