Dover Heights is a coastal, eastern suburb 9 kilometres east of the Sydney CBD.

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 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 Dover Heights area was subdivided in 1913.

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 Waverly Local Government Area, and amongst the most affluent suburbs in Sydney.

Dover Heights is a popular suburb for South African immigrants, with many residents also of the Jewish faith.
